AutoLayout--masonry使用

[label1 mas_makeConstraints:^(MASConstraintMaker *make) {

//使左边间距为

make.left.equalTo(self.view.mas_left).offset(11);

//顶部间距

make.top.equalTo(self.view.mas_top).offset(70);

//高度

make.height.equalTo(30);

}];

[label2 mas_makeConstraints:^(MASConstraintMaker *make) {

//使宽高等于label1

make.width.and.height.equalTo(label1);

//与label1顶部对齐

make.top.equalTo(label1.mas_top);

//与label1的间距为0

make.leading.equalTo(label1.mas_trailing).offset(10);

}];

[label3 mas_makeConstraints:^(MASConstraintMaker *make) {

//使宽高等于label2

make.width.and.height.equalTo(label2);

//与label2顶部对齐

make.top.equalTo(label2.mas_top);

//与label2的间距为0

make.leading.equalTo(label2.mas_trailing).offset(10);

//与父视图右边约束

make.right.equalTo(self.view.mas_right).offset(-11);

}];
