autoresizing mask是否适用于iPhoneX?

去年Apple推出What's New in Auto Layout时,一切正常没有约束

但是,当我在iPhoneX模拟器上尝试自动布局时,它不适用于安全区域

(✓使用安全区域布局指南)

Auto Layout (without constraint)

如果有人发现有任何替代方式,请在此处更新答案可能是我做错了

我尝试了一些东西,并在你需要的地方自定义,在这里我在viewcontroller中使用,代码是

基于你的视图在底部的

有一个按钮,在这里我计算sa

例如

@property (strong, nonatomic) IBOutlet UIButton *btnKarthik;

#pragma mark - Lifecycle
- (void)viewDidLoad
{
[super viewDidLoad];
CGRect modifyframe = self.btnKarthik.frame;
// here i changed the bottom origin Y position of my UIButton
modifyframe.origin.y = modifyframe.origin.y - [self getsafeAreaBottomMargin];
self.btnKarthik.frame = modifyframe;
}

常用方法是

- (CGFloat) getsafeAreaBottomMargin {
if (@available(iOS 11.0, *)) {
    UIWindow *currentwindow = UIApplication.sharedApplication.windows.firstObject;
    return currentwindow.safeAreaLayoutGuide.owningView.frame.size.height - currentwindow.safeAreaLayoutGuide.layoutFrame.size.height - currentwindow.safeAreaLayoutGuide.layoutFrame.origin.y;
} else {
    return 0;
}
}

Swift3及以上

override func viewDidLoad() {
    super.viewDidLoad()

    var modifyframe: CGRect = btnKarthik.frame
    // here i changed the bottom origin Y position of my UIButton
    modifyframe.origin.y = modifyframe.origin.y - getsafeAreaBottomMargin()
    btnKarthik.frame = modifyframe
}

常用方法

 func getsafeAreaBottomMargin() -> CGFloat {
   if #available(iOS 11.0, *) {
        let currentwindow = UIApplication.shared.windows.first
        return (currentwindow?.safeAreaLayoutGuide.owningView?.frame.size.height)! - (currentwindow?.safeAreaLayoutGuide.layoutFrame.size.height)! - (currentwindow?.safeAreaLayoutGuide.layoutFrame.origin.y)!
    }
    else {
        return 0
    }
}

输出iphone-X

将控件移离iPhone X上的边缘。在创建约束时使用安全区域布局指南和布局边距指南(如果手动设置框架,请使用safeAreaIsets或layoutMargins。

let margin = view.layoutMarginsGuide
NSLayoutConstraint.activate([
btnKarthik.leadingAnchor.constraint(equalTo: margin.leadingAnchor),
btnKarthik.bottomAnchor.constraint(equalTo: margin.bottomAnchor)
])
