iOS 项目常用方法集

1、改变 UITextField 占位文字 颜色和去掉底部白框

[_userName setValue:[UIColor whiteColor] forKeyPath:@"_placeholderLabel.textColor"];

//去掉底部白框[UIView setAnimationDuration:0.0];28[UIView beginAnimations:nil context:NULL];

2、禁止横屏 在Appdelegate 使用和判断程序是否第一次启动

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window

{

return UIInterfaceOrientationMaskPortrait;

}

//判断程序是否第一次启动

if(![[NSUserDefaultsstandardUserDefaults] boolForKey:@"firstLaunch"]){ [[NSUserDefaultsstandardUserDefaults] setBool:YESforKey:@"firstLaunch"];NSLog(@"第一次启动"); [[NSUserDefaultsstandardUserDefaults] setBool:NOforKey:@"isLogin"]; }else{NSLog(@"已经不是第一次启动了"); }

3、修改状态栏颜色 （默认黑色，修改为白色）

//1.在Info.plist中设置UIViewControllerBasedStatusBarAppearance 为NO

//2.在需要改变状态栏颜色的 AppDelegate中在 didFinishLaunchingWithOptions 方法中增加：

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

//3.如果需要在单个ViewController中添加，在ViewDidLoad方法中增加：

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

4、模糊效果

UIBlurEffect *effect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleLight];

UIVisualEffectView *test = [[UIVisualEffectView alloc] initWithEffect:effect];

test.frame = self.view.bounds;

test.alpha = 0.5;

[self.view addSubview:test];

5、强制横屏代码

#pragma mark - 强制横屏代码

- (BOOL)shouldAutorotate

{

//是否支持转屏

return NO;

}

- (UIInterfaceOrientationMask)supportedInterfaceOrientations

{

//支持哪些转屏方向

return UIInterfaceOrientationMaskLandscape;

}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation

{

return UIInterfaceOrientationLandscapeRight;

}

[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;

7、相对路径

$(SRCROOT)/

8、视图是否自动（只是把第一个自动）向下挪64

self.automaticallyAdjustsScrollViewInsets = NO; //不让系统帮咱们把scrollView及其子类的视图向下调整64

9、 隐藏手机的状态栏

-(BOOL)prefersStatusBarHidden {

return YES;

}

10、代理的安全保护【断是否有代理，和代理是否执行了代理方法】

if (self.delegate && [self.delegate respondsToSelector:@selector(passValueWithArray:)]) {

// make you codes

}

11、在ARC工程中导入MRC的类和在MRC工程中导入ARC的类

// 在ARC工程中导入MRC的类  我们选中工程->选中targets中的工程,然后选中Build Phases->在导入的类后边加入标记 -  fno-objc-arc

// 在MRC工程中导入ARC的类 路径与上面一致,在该类后面加上标记 -fobjc-arc

12、通过2D仿射函数实现小的动画效果(变大缩小) --可用于自定义pageControl中

[UIView animateWithDuration:0.3 animations:^{

imageView.transform = CGAffineTransformMakeScale(2, 2);

} completion:^(BOOL finished) {

imageView.transform = CGAffineTransformMakeScale(1.0, 1.0);

}];

13、查看系统所有字体

for (id familyName in [UIFont familyNames]) {

NSLog(@"%@", familyName);

for (id fontName in [UIFont fontNamesForFamilyName:familyName]) NSLog(@"  %@", fontName);

}

14、判断一个字符串是否为数字

NSCharacterSet *notDigits = [[NSCharacterSet decimalDigitCharacterSet] invertedSet];

if ([str rangeOfCharacterFromSet:notDigits].location == NSNotFound) {// 是数字

} else {// 不是数字

}

15、将一个view保存为pdf格式

- (void)createPDFfromUIView:(UIView*)aView saveToDocumentsWithFileName:(NSString*)aFilename

{

NSMutableData *pdfData = [NSMutableData data];

UIGraphicsBeginPDFContextToData(pdfData, aView.bounds, nil);

UIGraphicsBeginPDFPage();

CGContextRef pdfContext = UIGraphicsGetCurrentContext();

[aView.layer renderInContext:pdfContext];

UIGraphicsEndPDFContext();

NSArray* documentDirectories = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask,YES);

NSString* documentDirectory = [documentDirectories objectAtIndex:0];

NSString* documentDirectoryFilename = [documentDirectory stringByAppendingPathComponent:aFilename];

[pdfData writeToFile:documentDirectoryFilename atomically:YES];

NSLog(@"documentDirectoryFileName: %@",documentDirectoryFilename);

}

16、让一个view在父视图中心

child.center = [parent convertPoint:parent.center fromView:parent.superview];

17、获取当前导航控制器下前一个控制器

- (UIViewController *)backViewController

{

NSInteger myIndex = [self.navigationController.viewControllers indexOfObject:self];

if ( myIndex != 0 && myIndex != NSNotFound ) {

return [self.navigationController.viewControllers objectAtIndex:myIndex-1];

} else {

return nil;

}

}

18、保存UIImage到本地

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

NSString *filePath = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"Image.png"];

[UIImagePNGRepresentation(image) writeToFile:filePath atomically:YES];

19、键盘上方增加工具栏

UIToolbar *keyboardDoneButtonView = [[UIToolbar alloc] init];

[keyboardDoneButtonView sizeToFit];

UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithTitle:@"Done"

style:UIBarButtonItemStyleBordered target:self

action:@selector(doneClicked:)];

[keyboardDoneButtonView setItems:[NSArray arrayWithObjects:doneButton, nil]];

txtField.inputAccessoryView = keyboardDoneButtonView;

20、在image上绘制文字并生成新的image

UIFont *font = [UIFont boldSystemFontOfSize:12];

UIGraphicsBeginImageContext(image.size);

[image drawInRect:CGRectMake(0,0,image.size.width,image.size.height)];

CGRect rect = CGRectMake(point.x, point.y, image.size.width, image.size.height);

[[UIColor whiteColor] set];

[text drawInRect:CGRectIntegral(rect) withFont:font];

UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();

21、判断一个view是否为另一个view的子视图

// 如果myView是self.view本身，也会返回yes

BOOL isSubView = [myView isDescendantOfView:self.view];

22、判断一个字符串是否包含另一个字符串

// 方法一、这种方法只适用于iOS8之后，如果是配iOS8之前用方法二

if ([str containsString:otherStr]) NSLog(@"包含");

// 方法二

NSRange range = [str rangeOfString:otherStr];

if (range.location != NSNotFound) NSLog(@"包含");

23、判断某一行的cell是否已经显示

CGRect cellRect = [tableView rectForRowAtIndexPath:indexPath];

BOOL completelyVisible = CGRectContainsRect(tableView.bounds, cellRect);

24、让导航控制器pop回指定的控制器

else if(orientation == UIInterfaceOrientationLandscapeLeft)

// 左横屏

else if(orientation == UIInterfaceOrientationLandscapeRight)

//右横屏

26、UIWebView添加单击手势不响应

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(webViewClick)];

tap.delegate = self;

[_webView addGestureRecognizer:tap];

// 因为webView本身有一个单击手势，所以再添加会造成手势冲突，从而不响应。需要绑定手势代理，并实现下边的代理方法

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{

return YES;

}

27、获取手机RAM容量

// 需要导入#import

mach_port_t host_port;

mach_msg_type_number_t host_size;

vm_size_t pagesize;

host_port = mach_host_self();

host_size = sizeof(vm_statistics_data_t) / sizeof(integer_t);

host_page_size(host_port, &pagesize);

vm_statistics_data_t vm_stat;

if (host_statistics(host_port, HOST_VM_INFO, (host_info_t)&vm_stat, &host_size) != KERN_SUCCESS) {

NSLog(@"Failed to fetch vm statistics");

}

/* Stats in bytes */

natural_t mem_used = (vm_stat.active_count +

vm_stat.inactive_count +

vm_stat.wire_count) * pagesize;

natural_t mem_free = vm_stat.free_count * pagesize;

natural_t mem_total = mem_used + mem_free;

-(void)scrollViewDidScroll: (UIScrollView*)scrollView

{

float scrollViewHeight = scrollView.frame.size.height;

float scrollContentSizeHeight = scrollView.contentSize.height;

float scrollOffset = scrollView.contentOffset.y;

if (scrollOffset == 0)

{

// 滚动到了顶部

}

else if (scrollOffset + scrollViewHeight == scrollContentSizeHeight)

{

// 滚动到了底部

}

}

31、从导航控制器中删除某个控制器

// 方法一、知道这个控制器所处的导航控制器下标

NSMutableArray *navigationArray = [[NSMutableArray alloc] initWithArray: self.navigationController.viewControllers];

[navigationArray removeObjectAtIndex: 2];

self.navigationController.viewControllers = navigationArray;

// 方法二、知道具体是哪个控制器

NSArray* tempVCA = [self.navigationController viewControllers];

for(UIViewController *tempVC in tempVCA)

{

if([tempVC isKindOfClass:[urViewControllerClass class]])

{

[tempVC removeFromParentViewController];

}

}

{

NSData *data1 = UIImagePNGRepresentation(image1);

NSData *data2 = UIImagePNGRepresentation(image2);

return [data1 isEqual:data2];

}

34、代码方式调整屏幕亮度

// brightness属性值在0-1之间，0代表最小亮度，1代表最大亮度

[[UIScreen mainScreen] setBrightness:0.5];

35、根据经纬度获取城市等信息

// 创建经纬度

CLLocation *location = [[CLLocation alloc] initWithLatitude:latitude longitude:longitude];

//创建一个译码器

CLGeocoder *cLGeocoder = [[CLGeocoder alloc] init];

[cLGeocoder reverseGeocodeLocation:userLocation completionHandler:^(NSArray *placemarks, NSError *error) {

CLPlacemark *place = [placemarks objectAtIndex:0];

// 位置名

NSLog(@"name,%@",place.name);

// 街道

NSLog(@"thoroughfare,%@",place.thoroughfare);

// 子街道

NSLog(@"subThoroughfare,%@",place.subThoroughfare);

// 市

NSLog(@"locality,%@",place.locality);

// 区

NSLog(@"subLocality,%@",place.subLocality);

// 国家

NSLog(@"country,%@",place.country);

}

}];

36、如何防止添加多个NSNotification观察者？

// 解决方案就是添加观察者之前先移除下这个观察者

[[NSNotificationCenter defaultCenter] removeObserver:observer name:name object:object];

[[NSNotificationCenter defaultCenter] addObserver:observer selector:selector name:name object:object];

37、处理字符串，使其首字母大写

NSString *str = @"abcdefghijklmn";

NSString *resultStr;

if (str && str.length > 0) {

resultStr = [str stringByReplacingCharactersInRange:NSMakeRange(0,1) withString:[[str substringToIndex:1] capitalizedString]];

}

NSLog(@"%@", resultStr);

38、获取字符串中的数字

- (NSString *)getNumberFromStr:(NSString *)str

{

NSCharacterSet *nonDigitCharacterSet = [[NSCharacterSet decimalDigitCharacterSet] invertedSet];

return [[str componentsSeparatedByCharactersInSet:nonDigitCharacterSet] componentsJoinedByString:@""];

}

39、为UIView的某个方向添加边框

- (void)wzb_addBorder:(WZBBorderDirectionType)direction color:(UIColor *)color width:(CGFloat)width

{

CALayer *border = [CALayer layer];

border.backgroundColor = color.CGColor;

switch (direction) {

case WZBBorderDirectionTop:

{

border.frame = CGRectMake(0.0f, 0.0f, self.bounds.size.width, width);

}

break;

case WZBBorderDirectionLeft:

{

border.frame = CGRectMake(0.0f, 0.0f, width, self.bounds.size.height);

}

break;

case WZBBorderDirectionBottom:

{

border.frame = CGRectMake(0.0f, self.bounds.size.height - width, self.bounds.size.width, width);

}

break;

case WZBBorderDirectionRight:

{

border.frame = CGRectMake(self.bounds.size.width - width, 0, width, self.bounds.size.height);

}

break;

default:

break;

}

[self.layer addSublayer:border];

}

40、自动搜索功能，用户连续输入的时候不搜索，用户停止输入的时候自动搜索(我这里设置的是0.5s，可根据需求更改)

// 输入框文字改变的时候调用

-(void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText{

// 先取消调用搜索方法

[NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(searchNewResult) object:nil];

// 0.5秒后调用搜索方法

[self performSelector:@selector(searchNewResult) withObject:nil afterDelay:0.5];

}

41、修改UISearchBar的占位文字颜色

// 方法一（推荐使用）

UITextField *searchField = [searchBar valueForKey:@"_searchField"];

[searchField setValue:[UIColor blueColor] forKeyPath:@"_placeholderLabel.textColor"];

// 方法二（已过期）

[[UILabel appearanceWhenContainedIn:[UISearchBar class], nil] setTextColor:[UIColor redColor]];

// 方法三（已过期）

NSDictionary *placeholderAttributes = @{NSForegroundColorAttributeName : [UIColor redColor], NSFontAttributeName : [UIFont fontWithName:@"HelveticaNeue" size:15],};

NSAttributedString *attributedPlaceholder = [[NSAttributedString alloc] initWithString:searchBar.placeholder attributes:placeholderAttributes];

[[UITextField appearanceWhenContainedIn:[UISearchBar class], nil] setAttributedPlaceholder:attributedPlaceholder];

42、动画执行removeFromSuperview

animations:^{

view.alpha = 0.0f;

} completion:^(BOOL finished){

[view removeFromSuperview];

}];

43、修改image颜色

UIImage *image = [UIImage imageNamed:@"test"];

imageView.image = [image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];

CGRect rect = CGRectMake(0, 0, image.size.width, image.size.height);

UIGraphicsBeginImageContext(rect.size);

CGContextRef context = UIGraphicsGetCurrentContext();

CGContextClipToMask(context, rect, image.CGImage);

CGContextSetFillColorWithColor(context, [[UIColor redColor] CGColor]);

CGContextFillRect(context, rect);

UIImage *img = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();

UIImage *flippedImage = [UIImage imageWithCGImage:img.CGImage scale:1.0 orientation: UIImageOrientationDownMirrored];

imageView.image = flippedImage;

44、利用runtime获取一个类所有属性

- (NSArray *)allPropertyNames:(Class)aClass

{

unsigned count;

objc_property_t *properties = class_copyPropertyList(aClass, &count);

NSMutableArray *rv = [NSMutableArray array];

unsigned i;

for (i = 0; i < count; i++)

{

objc_property_t property = properties[i];

NSString *name = [NSString stringWithUTF8String:property_getName(property)];

[rv addObject:name];

}

free(properties);

return rv;

}

45、让push跳转动画像modal跳转动画那样效果(从下往上推上来)

- (void)push

{

TestViewController *vc = [[TestViewController alloc] init];

vc.view.backgroundColor = [UIColor redColor];

CATransition* transition = [CATransition animation];

transition.duration = 0.4f;

transition.type = kCATransitionMoveIn;

transition.subtype = kCATransitionFromTop;

[self.navigationController.view.layer addAnimation:transition forKey:kCATransition];

[self.navigationController pushViewController:vc animated:NO];

}

- (void)pop

{

CATransition* transition = [CATransition animation];

transition.duration = 0.4f;

// 创建一个富文本

NSMutableAttributedString * attriStr = [[NSMutableAttributedString alloc] initWithString:contentStr];

//// 修改富文本中的不同文字的样式

//[attriStr addAttribute:NSForegroundColorAttributeName value:[UIColor blackColor] range:NSMakeRange(0, 5)];

}

}

[self.navigationController popToViewController:getmoney animated:YES];

58.APP启动界面的动画

UIImageView *welcome = [[UIImageView alloc]initWithFrame:_window.bounds];

[welcome setImage:[UIImage imageNamed:@"HJLaunchImage"]];

//把背景图放在最上层

[_window addSubview:welcome];

[_window bringSubviewToFront:welcome];

welcome.alpha = 0.99;//这里alpha的值和下面alpha的值不能设置为相同的，否则动画相当于瞬间执行完，启动页之后动画瞬间消失。这里alpha设为0.99，动画就不会有一闪而过的效果，而是一种类似于静态背景的效果。设为0，动画就相当于是淡入的效果了。

[UIView animateWithDuration:1.0f delay:0.0f options:UIViewAnimationOptionTransitionCrossDissolve animations:^{

CGRect frame = welcome.frame;

frame.size.width = _window.size.width*1.3;

frame.size.height = _window.size.height*1.3;

NSString *firstAddress = self.provinceArr[self.index1];

[detailAddress appendString:firstAddress];//拼接字符串

}

61.//计算时间差0年0月1日1小时51分钟55秒

// 1.确定时间

NSString *time1 = @"2015-09-8 10:18:15";

NSString *time2 = @"2015-09-9 12:10:10";

// 2.将时间转换为date

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];

formatter.dateFormat = @"yyyy-MM-dd HH:mm:ss";

NSDate *date1 = [formatter dateFromString:time1];

NSDate *date2 = [formatter dateFromString:time2];

// 3.创建日历

NSCalendar *calendar = [NSCalendar currentCalendar];

NSCalendarUnit type = NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitDay | NSCalendarUnitHour | NSCalendarUnitMinute | NSCalendarUnitSecond;

// 4.利用日历对象比较两个时间的差值

NSDateComponents *cmps = [calendar components:type fromDate:date1 toDate:date2 options:0];

// 5.输出结果

NSIndexPath *indexPath = [NSIndexPath indexPathForItem:i inSection:0];

NSString *resuID =[NSString stringWithFormat:@"inputCell_%ld",(long)indexPath.row];

InputTableViewCell *inpCell = [self.tableView dequeueReusableCellWithIdentifier:resuID];

66.在Appdelegate.m中的didFinishLaunchingWithOptions

方法中添加如下代码，就全局搞定了！

if (@available(ios 11.0,*))

{

UIScrollView.appearance.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentNever;

UITableView.appearance.estimatedRowHeight = 0;

UITableView.appearance.estimatedSectionFooterHeight = 0;

UITableView.appearance.estimatedSectionHeaderHeight = 0;

}

67.数据存储3种方式：

1.writeToFile

//1.1 你需要获取路径

NSString *path = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];

// .XXX 尾椎 只是决定 以哪中方式查看数据, 对存入的数据本身没有影响

NSString *fiflePath = [path stringByAppendingPathComponent:@"data.XXX"];

fileSizeText = [NSString stringWithFormat:@"%.2fKB", fileSize / unit];

} else { // fileSize < 1KB

fileSizeText = [NSString stringWithFormat:@"%zdB", fileSize];

}    return fileSizeText;

}

//清空缓存

+(BOOL)CleanCacheFilePath{

//拿到path路径的下一级目录的子文件夹

continue;

}

}

return YES;

}

//SDWebImage清理缓存

// 清理内存

[[SDImageCache sharedImageCache] clearMemory];

// 清理webview 缓存

NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];

for (NSHTTPCookie *cookie in [storage cookies]) {

[storage deleteCookie:cookie];

}

NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];

[config.URLCache removeAllCachedResponses];

[[NSURLCache sharedURLCache] removeAllCachedResponses];

// 清理硬盘

[[SDImageCache sharedImageCache] clearDiskOnCompletion:^{

//[MBProgressHUD hideAllHUDsForView:self.view animated:YES];

//[self.tableView reloadData];

}];
