Masonry 布局基本操作小结

呐，Masonry 是用来布局的！CocoaPods上下载！

呐，来吧！开始鸟语......下面是从View+MASAdditions.h中抽出来的方法。

 1 /**
 2  *  Creates a MASConstraintMaker with the callee view.
 3  *  Any constraints defined are added to the view or the appropriate superview once the block has finished executing
 4  *
 5  *  @param block scope within which you can build up the constraints which you wish to apply to the view.
 6  *
 7  *  @return Array of created MASConstraints
 8  */
 9 - (NSArray *)mas_makeConstraints:(void(^)(MASConstraintMaker *make))block;
10 
11 /**
12  *  Creates a MASConstraintMaker with the callee view.
13  *  Any constraints defined are added to the view or the appropriate superview once the block has finished executing.
14  *  If an existing constraint exists then it will be updated instead.
15  *
16  *  @param block scope within which you can build up the constraints which you wish to apply to the view.
17  *
18  *  @return Array of created/updated MASConstraints
19  */
20 - (NSArray *)mas_updateConstraints:(void(^)(MASConstraintMaker *make))block;
21 
22 /**
23  *  Creates a MASConstraintMaker with the callee view.
24  *  Any constraints defined are added to the view or the appropriate superview once the block has finished executing.
25  *  All constraints previously installed for the view will be removed.
26  *
27  *  @param block scope within which you can build up the constraints which you wish to apply to the view.
28  *
29  *  @return Array of created/updated MASConstraints
30  */
31 - (NSArray *)mas_remakeConstraints:(void(^)(MASConstraintMaker *make))block;

土鳖式翻译开始... 对比：

mas_makeConstraints 　　 　created

mas_updateConstraints　  　created/updated　　 If an existing constraint exists then it will be updated instead.
　　　　　　　　　　　　　　　　　　　　　　　　　　（如果现有的约束存在,那么它将被更新。）

mas_remakeConstraints　　 　created/updated　　All constraints previously installed for the view will be removed.

　　　　　　　　　　　　　　　　　　　　　　　　　　（视图上之前安装的所有约束将被删除。人家的意思是会保留最新哒）

简单使用方法：

人家想来个全屏的么，除了导航栏。

1  [myView mas_makeConstraints:^(MASConstraintMaker *make) {
2         make.top.equalTo(self.view.mas_top).with.offset(64);//上
3         make.left.equalTo(self.view.mas_left);    //左
4         make.right.equalTo(self.view.mas_right);//右
5         make.bottom.equalTo(self.view.mas_bottom);//下
6     }];

其他方法自行脑补~揍四Autolayout。

下面贴个详细的帖子，I like ~~~ http://adad184.com/2014/09/28/use-masonry-to-quick-solve-autolayout/
