Question

自动布局第三方masory如何使用topLayoutGuide？如题

Answer 1

topLayoutGuide 和 bottomLayoutGuide These are attributes added to UIViewController after iOS 7.

topLayoutGuide usually represents the upper part of the current page blocked by StatusBar and NavigationBar. This can be used in Masonry’s API:

[myView mas_makeConstraints:^(MASConstraintMaker *make) {
    // 把 myView 的 top 和 self(UIViewController) 的 topLayoutGuide 的那部分界面的 top 对齐。
    make.top.equalTo(self.mas_topLayoutGuide);
    // ...
}];
