居中显示

make.center.equalTo(self.view);

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

让一个view略小于其superView(边距为10)

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

/* 等价于

make.top.equalTo(sv).with.offset(10);

make.left.equalTo(sv).with.offset(10);

make.bottom.equalTo(sv).with.offset(-10);

make.right.equalTo(sv).with.offset(-10);

*/

/* 也等价于

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

*/

让两个高度为150的view垂直居中且等宽且等间隔排列 间隔为10(自动计算其宽度)

int padding1 = 10;

[sv2 mas_makeConstraints:^(MASConstraintMaker *make) {

make.centerY.mas_equalTo(sv.mas_centerY);

make.left.equalTo(sv.mas_left).with.offset(padding1);

make.right.equalTo(sv3.mas_left).with.offset(-padding1);

make.height.mas_equalTo(@150);

make.width.equalTo(sv3);

}];

[sv3 mas_makeConstraints:^(MASConstraintMaker *make) {

make.centerY.mas_equalTo(sv.mas_centerY);

make.left.equalTo(sv2.mas_right).with.offset(padding1);

make.right.equalTo(sv.mas_right).with.offset(-padding1);

make.height.mas_equalTo(@150);

make.width.equalTo(sv2);

}];
