第三方自动布局框架--Masonry

这个框架方便简单

框架连接:https://github.com/SnapKit/Masonry
参考于:http://www.th7.cn/Program/IOS/201502/390670.shtml

使用时直接导入头文件即可Masonry.h

- (void)viewDidLoad {
  
    [super viewDidLoad];
    
    [self addMasory];
    
}
-(void)addMasory
{

    UIView *view1=[UIView new];
    [view1 setBackgroundColor:[UIColor redColor]];
    [self.view addSubview:view1];
    UIView *view2=[UIView new];
    [view2 setBackgroundColor:[UIColor blackColor]];
    [self.view addSubview:view2];
    
[view1 mas_makeConstraints:^(MASConstraintMaker *make) {
    make.left.equalTo(self.view.mas_left).offset(30);
    make.bottom.equalTo(self.view.mas_bottom).offset(-30);
    make.right.equalTo(view2.mas_left).offset(-30);
    make.height.mas_equalTo(50);
    
}];
[view2 mas_makeConstraints:^(MASConstraintMaker *make) {
    make.right.equalTo(self.view.mas_right).offset(-30);
    make.bottom.equalTo(view1.mas_bottom);
    make.height.equalTo(view1.mas_height);
    make.width.equalTo(view1.mas_width);
}];
    
}

实现的效果如图:
