问题 I am trying (...) to add a sound effect to the buttons added to a UIAlertController. I fire a sound effect in the handler, but this actually is a bit too late. The sound fires like 0.5 seconds too late. I want the sound to fire as soon as the alert is about to dismiss, not after it has dismissed. With UIAlertView this was possible to handle using alertWillDismiss... rather than alertDidDismiss. Did I miss something? 回答1: No, you didn't miss anything. The functionality you're looking for is

inputAccessoryView animating down when alertController (actionSheet) presented

由 心已入冬 提交于 2019-12-07 02:29:03
问题 I have an inputAccessoryView for a chat app that always remains visible and docked at the bottom of the screen for text input similar to most messaging apps. When I present an alertController with actionSheet style, the inputAccessoryView animates down off screen as the alert is presented and then back up again when the alert is dismissed. This in turn scrolls my tableView and is undesirable. This is happening because the chat viewController is giving up firstResponder when the alert is

The alert view is trying to display, but getting this error: Warning: Attempt to present <UIAlertController: 0x147d2c6b0> on <LiveDeadApp

However, I'm having real trouble doing this. On the line where I add the action I get the following error: 'UIViewController?' is not a subtype of Void let alertController = UIAlertController(title: "Oops", message: "We
