ios13

问题 On iOS 13, when presenting a second modal view controller over a first one, the padding is incorrect on the button bar items. In particular, the right margin disappears. How should this be fixed? 回答1: This behavior is due to a bug in iOS 13. It can be fixed by calling setNeedsLayout on the Navigation Bar. Swift example: override func viewWillAppear(_ animated: Bool) { super.viewWillAppear(animated) if #available(iOS 13.0, *) { navigationController?.navigationBar.setNeedsLayout() } } Objective

问题 Prior to the release of iOS 13, I had had some CATransform3D code inside a UIView.animate block. In iOS 12, the result of the transformation animation looked like this: https://youtu.be/mfIzjjlKOBM. In iOS 13, the same transformation code now gives this result: https://youtu.be/hQdyGactIfA. As you can see in iOS 13 the animation is no longer a fluid cube movement like it is in iOS 12. Here's my basic code: UIView.animate(withDuration: duration, delay: 0, options: .curveEaseOut, animations: {

问题 We currently have a solution to send the push notification from FCM to APNS and then to iOS.

And we follow this page as reference: https://firebase.google.com/docs/cloud-messaging/http

问题 As per the WWDC video, https://developer.apple.com/videos/play/wwdc2019/705/, when you ask for " AlwaysAuthorization " permission you will see only " When In Use, Once and Don't allow" . Even if you tap on " When In Use ", the delegate call back will come back as kCLAuthorizationStatusAuthorizedAlways . This is working as expected. But is there a way to find out that the request is still provisional or actually-always-allow? There is no enum associated to this permission. The only allowed
