当你打开 View 时，它看起来像下图，
对于 iphone x，我想在当前 View 中以编程方式添加一个安全区域。
源码如下。
UIView *view = self.view;
if (@available(iOS 11.0, *)) {
UILayoutGuide * guide = view.safeAreaLayoutGuide;
[view.topAnchor constraintEqualToAnchor:guide.topAnchor].active = YES;
[view.bottomAnchor constraintEqualToAnchor:guide.bottomAnchor].active = YES;
}
我想应用这个源，但我不知道该怎么做。
请回答我的问题!
最佳答案
这是安全区域布局的示例代码。在 Objective-C 中试试看:
UIView * myView = // initialize view using IBOutlet or programtically
myView.backgroundColor = [UIColor red];
myView.translatesAutoresizingMaskIntoConstraints = NO;
UILayoutGuide * guide = self.view.safeAreaLayoutGuide;
[self.myView.leadingAnchor constraintEqualToAnchor:guide.leadingAnchor].active = YES;
[self.myView.trailingAnchor constraintEqualToAnchor:guide.trailingAnchor].active = YES;
[self.myView.topAnchor constraintEqualToAnchor:guide.topAnchor].active = YES;
[self.myView.bottomAnchor constraintEqualToAnchor:guide.bottomAnchor].active = YES;
// Refresh myView and/or main view
[self.view layoutIfNeeded];
//[self.myView layoutIfNeeded];
