一些方法：
计算字体高/宽度、获取拼音方法

视图效果：抖动动画、圆角、阴影效果

导航栏颜色、摁扭

网页搜索

状态栏颜色

调用系统摄像头、图库、相册

一些判断：
定位权限、摄像头、系统版本、判断设备

ios10权限

常用宏：颜色、适配、屏幕尺寸

控件：
scrollview:滑动方向、隐藏滑条、某个方向的弹性

cell:cell内数据、分割线起止位置、注册、选中效果

UItableview:策划删除、隐藏空数据cell、滑动到指定行

UItoolbar:弹性撑开效果

UIButton:点击阴影效果、点击效果、选中状态切换

UIlable:富文本、截断类型、居上居下显示

UIview:增加手势

UItextfield:添加点击事件、纯数字判断

UITextView:添加假placeholder、限制文字数量

mac指令

显示隐藏文件:

defaults write com.apple.finder AppleShowAllFiles -bool true

隐藏隐藏文件:

defaults write com.apple.finder AppleShowAllFiles -bool false
开启本机服务器:

sudo apachectl -k start
sudo apachectl -k restart
显示日历：

cal 8 2016

不进入睡眠状态：

caffeinate -t 3600

释放内存：

purge

隐藏指定文件：
如果你想让某个文件或文件夹影藏，那么chflags命令可以实现。你只需将文件路径填对即可，比如我们向隐藏桌面上的macx文件夹。如果你想再次看到文件夹，只需将hidden改为nohidden即可。

chflags hidden ~/Desktop/macx

创建密码保护zip：
-r 包含子文件/文件夹
-e 加密
-m 压缩完删除原文件
-o 设置所有被压缩文件的最后修改时间为当前压缩时间

zip -e protected.zip ~/Desktop/macx.txt
文件夹：
zip -r -e 破解.zip ~/desktop/破解
直接加密：
zip -r -P 690658234 破解.zip 破解

>状态栏颜色

1在Info.plist中设置UIViewControllerBasedStatusBarAppearance 为NO
2 在需要改变状态栏颜色的ViewController中在ViewDidLoad方法中增加：
[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

如果需要在全部View中都变色，可以写在父类的相关方法中，或者写到AppDelegate中。

>判断定位权限

if ([CLLocationManager locationServicesEnabled] && ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusAuthorizedWhenInUse || [CLLocationManager authorizationStatus] == kCLAuthorizationStatusNotDetermined || [CLLocationManager authorizationStatus] == kCLAuthorizationStatusAuthorized)) {

//定位功能可用

}else if ([CLLocationManager authorizationStatus] ==kCLAuthorizationStatusDenied) {

//定位不能用

}

判断是否有摄像头

  if ([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera]){
