Masonry

一般使用equalTo

  1、在block中使用self要用__block修饰
__block typeof(self)weakself = self;
2、
        
        self.pictureImageview = [[UIImageView alloc] init];
        [self.contentView addSubview:self.pictureImageview];
        self.imageView.image = [UIImage imageNamed:@"dingwei"];
        [self.pictureImageview mas_makeConstraints:^(MASConstraintMaker *make) {
            make.top.equalTo(weakself).offset(5);
            make.bottom.equalTo(weakself).offset(5);
            make.width.mas_equalTo(50);
            make.left.equalTo(weakself).offset(5);
        }];
        
        
        
        self.titleLable = [[UILabel alloc] init];
        self.titleLable.backgroundColor = [UIColor redColor];
        [self.contentView addSubview:self.titleLable];
        [self.titleLable mas_makeConstraints:^(MASConstraintMaker *make) {
         3、self.titleLable距self.pictureImageview5个像素
            make.left.equalTo(self.pictureImageview.mas_right).offset(5);
            make.top.equalTo(self.pictureImageview);
            make.width.mas_equalTo(44);
          4、一个控件是另一个控件高度的三分之一
            make.height.equalTo(weakself.mas_height).multipliedBy(0.33);
        }];
