问题 I want UIAlertController to present an alert with UIImageView in an ActionSheet . But when I run the application it is terminating.

问题 In iOS 8 and lower show a UIActionSheet when keyboard is presented will present the action sheet over the keyboard. With iOS 9 this is no longer the case. In my app we have a chat functionality and want the show a action over the keyboard. We used to use UIActionSheet which worked fine until iOS 8.

问题 My alert looks like this: Is it possible to make inputs bigger and add space between them? Here is a snippet from my code. I tried changing the frame property of the second text field but it didn't help: let alert = UIAlertController(title: title, message: message, preferredStyle: .Alert) // Add the textfields alert.addTextFieldWithConfigurationHandler({ (textField) -> Void in textField.placeholder = "Vaše jméno" }) alert.addTextFieldWithConfigurationHandler({ (textField) -> Void in textField

问题 I used to have a "Please wait" dialog in my app for long time. It was quite simple thing using UIActivityIndicatorView and adding it to UIAlertView . However iOS8 introduced UIAlertController . Is it possible to add anything to it to have similiar effect? Is there another way of doing such thing with iOS8? I have searched a lot of sites and still have no idea how it can be done with the new API. I would appreciate any answers - links to libs, tutorials etc., which could be helpful. Regards,

问题 It appears that UIAlertView is not compatible with iOS8. I've just discovered that all my multiline UIAlertViews become truncated one-liners in iOS8 (for the message). In iOS7 they are displayed correctly with multilines. iOS7: iOS8: [[[UIAlertView alloc] initWithTitle:@"Namn saknas" message:@"Du måste fylla i ditt namn för att kommentera" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil] show]; I'm aware of that UIAlertController should be used in iOS8 and later and that

问题 I have added a UITextField in a UIAlertController . I want to change the height of the text field. I have tried this way: let alertController = UIAlertController(title: "Comments", message: "Write your comments here", preferredStyle: UIAlertControllerStyle.alert) alertController.addTextField { (textField : UITextField) -> Void in var frame: CGRect = textField.frame frame.size.height = 100 textField.frame = frame textField.placeholder = "comment" print(textField.frame.size.height) } let

问题 Previous to iOS8 we used the UIActionSheet for showing alert and now we need to use the UIAlertController. When we used the UIActionSheet we could easily handle situations where the user clicked outside the pop up (which means he want to cancel the operation) by comparing the clickedButtonAtIndex to the cancelButtonIndex - if the user indeed pressed outside the popup we got the cancel button index in this function. How can we handle these situations with the new UIAlertController? I tried to

问题 Showing a UIPickerView with UIActionSheet in iOS8 not working The code works in iOS7 , however it is not working in iOS8 . I'm sure it is because UIActionSheet is deprecated in iOS8 and Apple recommends to use UIAlertController . However, how to do it in iOS8 ? I should use UIAlertController ? iOS7 : iOS8 : EDIT: My GitHub project solving the problem. 回答1: From the reference for UIActionSheet: UIActionSheet is not designed to be subclassed, nor should you add views to its hierarchy. If you

问题 I'm trying to make an alert message with input, and then get the value from the input. I've found many good tutorials how to make the input text field. but I can't get the value from the alert. 回答1: Updated for Swift 3 and above: //1.
