masonry

UIView *myView = nil

[self.window addSubview:myView];

//使用之前要先将试图添加到俯视图上 然后再约束 

[myView mas_makeConstraints:^(MASConstraintMaker *make){

　　make.center.equalTo(self.window);

　　make.size.mas_equalTo(CGSizeMake(300, 300));

}];

mas_makeConstraints 新增约束

mas_updateConstraints 更新

mas_remakeConstraints 移除

mas_equalTo  ：NSNumber CGPoint CGSize UIEdgeInsets

[myView mas_makeConstraints:^(MASConstraintMaker *make){

　　make.top.left.bottom.and.right.equalTo(self.window).with.insets(UIEdgeInsetsMake(10,10,10,10));

}];

[myView mas_makeConstraints:^(MASConstraintMaker *make){

　　make.edges.equalTo(self.window).with.insets(UIEdgeInsetsMake(10,10,10,10));

}];

[myView mas_makeConstraints:^(MASConstraintMaker *make){

　　make.top.equalTo(self.window).with.offset(15);

　　make.left.equalTo(self.window).with.offset(15);

　　make.bottom.equalTo(self.window).with.offset(-15);

　　make.right.equalTo(self.window).with.offset(-15);

 

}];
