NSString扩展
.h中-需要pod 'CocoaSecurity'
@interface NSString(extend)
- (NSString *)md5;/*md5加密*/
- (NSString*)base64_encode;/*base64加密*/
- (NSString*)base64_decode;/*base64解密*/
+ (NSString*)app_version;/*当前app版本*/
+ (NSString *)stringWithDate:(NSDate *)date dateFormat:(NSString *)dateFormat;/*将日期转化成字符串*/
+ (NSString *)className:(Class)_class;/*将类名转换成字符串*/
+ (NSString *)strWithDoubNum:(double)doubleNumber;/*统一项目中小数的位数*/
@end
.m中
@implementation NSString (extend)
- (NSString *)md5
{
CocoaSecurityResult* e = [CocoaSecurity md5:self];
return e.hexLower;
}
- (NSString *)base64_encode
{
NSData* data = [self dataUsingEncoding:NSUTF8StringEncoding];
CocoaSecurityEncoder* e = [[CocoaSecurityEncoder alloc] init];
return [e base64:data];
}
- (NSString *)base64_decode
{
CocoaSecurityDecoder* e = [[CocoaSecurityDecoder alloc] init];
NSString* ret = [[NSString alloc] initWithData:[e base64:self] encoding:NSUTF8StringEncoding];
return ret;
}
+ (NSString *)app_version
{
NSDictionary *info = [[NSBundle mainBundle] infoDictionary];
NSString *version = [info objectForKey:@"CFBundleShortVersionString"];
//NSLog(@"appver:%@",version);
return version;
}
+ (NSString *)stringWithDate:(NSDate *)date dateFormat:(NSString *)dateFormat
{
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:dateFormat];
return [formatter stringFromDate:date];
}
+ (NSString *)className:(Class)_class
{
return [NSString stringWithUTF8String:object_getClassName(_class)];
}
+ (NSString *)strWithDoubNum:(double)doubleNumber
{
return [NSString stringWithFormat:@"%.02lf",doubleNumber];
}
@end
UIImage扩展-改变image填充色
.h中-通过代码改变imag的填充色
@interface UIImage (extend)
- (UIImage *)imageWithTintColor:(UIColor *)tintColor;
- (UIImage *)imageWithGradientTintColor:(UIColor *)tintColor;
@end
.m中
- (UIImage *)imageWithTintColor:(UIColor *)tintColor
{
return [self imageWithTintColor:tintColor blendMode:kCGBlendModeDestinationIn];
}
- (UIImage *)imageWithGradientTintColor:(UIColor *)tintColor
{
return [self imageWithTintColor:tintColor blendMode:kCGBlendModeOverlay];
}
- (UIImage *)imageWithTintColor:(UIColor *)tintColor blendMode:(CGBlendMode)blendMode
{
UIGraphicsBeginImageContextWithOptions(self.size, NO, 0.0f);
[tintColor setFill];
CGRect bounds = CGRectMake(0, 0, self.size.width, self.size.height);
UIRectFill(bounds);
[self drawInRect:bounds blendMode:blendMode alpha:1.0f];
if (blendMode != kCGBlendModeDestinationIn) {
[self drawInRect:bounds blendMode:kCGBlendModeDestinationIn alpha:1.0f];
}
UIImage *tintedImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return tintedImage;
}
NSDate扩展-将字符串变为NSDate
.h中
@interface NSDate (extend)
+ (NSDate *)dateWithString:(NSString *)string dateFormat:(NSString *)dateFormat;
@end
.m中
@implementation NSDate (extend)
+ (NSDate *)dateWithString:(NSString *)string dateFormat:(NSString *)dateFormat
{
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:dateFormat];
return [formatter dateFromString:string];
}
@end
