在使用masnory适配的时候，有些方法记不住，特此笔记记录。
1、居中设置
垂直居中：make.centerY.mas_equalTo(self.window.mas_centerY)
水平居中：make.centerX.mas_equalTo(self.window.mas_centerX)
全屏居中：make.center.equalTo(self.window)
2、边界设置
上边界：make.top.equalTo(self.window).with.offset(15.0)
左边界：make.left.equalTo(self.window).with.offset(15.0)
下边界：make.bottom.equalTo(self.window).with.offset(-15.0)
右边界：make.right.equalTo(self.window).with.offset(-15.0)
或：
上边界：make.top.mas_equalTo(15.0)
左边界：make.left.mas_equalTo(15.0)
下边界：make.bottom.mas_equalTo(-15.0)
右边界：make.right.mas_equalTo(-15.0)
或：
上边界、左边界：make.top.left.mas_equalTo(15.0)
下边界、右边界：make.bottom.right.mas_equalTo(-15.0)
或：make.top.left.bottom.and.right.equalTo(self.window).with.insets(UIEdgeInsetsMake(15.0,15.0,15.0,15.0))
或：make.edges.equalTo(self.window).with.insets(UIEdgeInsetsMake(15.0,15.0,15.0,15.0))
与另一个视图的边界间距设置
与另一个视图右部边界间距：make.right.mas_equalTo(currentView.mas_left).offset(10.0);
与另一个视图底部边界间距：make.top.mas_equalTo(currentView.mas_bottom).offset(10.0);
3、倍数设置
设置宽度为self.view的一半，multipliedBy是倍数的意思，也就是，使宽度等于self.view宽度的0.5倍
make.width.equalTo(self.view.mas_width).multipliedBy(0.5);
设置高度为self.view高度的一半
make.height.equalTo(self.view.mas_height).multipliedBy(0.5);
4、大小设置
宽：
make.width.equalTo(self.view.mas_width).multipliedBy(0.5);
或：make.width. mas_equalTo(320.0).multipliedBy(0.5);
或：make.width. mas_equalTo(160.0);
高：make.height.equalTo(self.view.mas_height).multipliedBy(0.5);
或：make.height. mas_equalTo(320.0).multipliedBy(0.5);
或：make.height. mas_equalTo(160.0);
size：make.size. mas_equalTo(CGSizeMake(300.0,50.0));
或：make.size.equalTo(view);
或：make.size.mas_equalTo(CGSizeMake(150.0,50.0)).multipliedBy(0.5);
4、将若干view等宽布局于容器containerView中
-(void)makeEqualWidthViews:(NSArray *)views inView:(UIView *)containerView LRpadding:(CGFloat)LRpadding viewPadding :(CGFloat)viewPadding
{
UIView *lastView;
for (UIView *view in views) {
[containerView addSubview:view];
if (lastView) {
[view mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.bottom.equalTo(containerView);
make.left.equalTo(lastView.mas_right).offset(viewPadding);
make.width.equalTo(lastView);
}];
}else
{
[view mas_makeConstraints:^(MASConstraintMaker *make) {
make.left.equalTo(containerView).offset(LRpadding);
make.top.bottom.equalTo(containerView);
}];
}
lastView=view;
}
[lastView mas_makeConstraints:^(MASConstraintMaker *make) {
make.right.equalTo(containerView).offset(-LRpadding);
}];
}
5、实现n宫格布局
6、移除约束重新布局
remake会将之前的全部移除，然后重新添加
// remake会将之前的全部移除，然后重新添加
[self.growingButton mas_remakeConstraints:^(MASConstraintMaker *make) {
make.top.mas_equalTo(0);
make.left.right.mas_equalTo(0);
}];
// 告诉self.view约束需要更新
[self.view setNeedsUpdateConstraints];
// 调用此方法告诉self.view检测是否需要更新约束，若需要则更新，下面添加动画效果才起作用
[self.view updateConstraintsIfNeeded];
