safearealayoutguide

问题 Without using safeAreaLayoutGuide (I am targeting IOS 9+), is there any way to programmatically get the height of the "safe area" in IOS without having to create a new view (constrained to the safe area) solely for this purpose? I can't set an outlet to the safe area because it's not a UIView... or even a class of any sort. And if I simply use self.view.height in the ViewController, it's going to be too high (wrong). Is there some other way to do it? 回答1: In a UIViewController you can use the

问题 Here's a collection view constrained to top, left, right, and bottom of the superview with safe area layout guide enabled: I want my collection view header to be shown under the status bar. I've achieved this for iPhone 4 - 8+ screen dimensions by unchecking Safe Area Layout Guide in the size inspector for the controller's main view , and adding the following code: collectionView.contentInset = UIEdgeInsets(top: -20, left: 0, bottom: 0, right: 0) This looks great for non iPhone X view sizes:

问题 I have a problem in iOS11 with the iPhoneX simulator. I have a viewcontroller without the statusbar. To do this I add: - (BOOL)prefersStatusBarHidden { return YES; } It is good so far but the navigationbar overlaps the safearea in the iPhoneX. How can I fix this? 回答1: Finally the solution was using safeAreaInsets if (@available(iOS 11.0, *)) { UIEdgeInsets safeInsets = UIApplication.sharedApplication.delegate.window.safeAreaInsets; paddingTop = safeInsets.top; } You can do this

问题 The new Safe Area layout guide introduced in iOS 11 works great to prevent content from displaying below bars, but it excludes the keyboard. That means that when a keyboard is displayed, content is still hidden behind it and this is the problem I am trying to solve. My approach is based on listening to keyboard notifications and then adjusting the safe area through additionalSafeAreaInsets . Here is my code: override func viewDidLoad() { let notificationCenter = NotificationCenter.default

问题 By default the statusbar on an iPhone X looks like this: But I would like to achieve this: I tried setting the preferredStatusBarStyle to lightContent but it only worked after setting the background behind the statusbar to black. To fix the rounded corners I ended up adding another subview with rounded corners. class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() view.backgroundColor = .black let roundedView = UIView( frame: CGRect( x: 0, y: UIApplication
