问题 Apple recommends dismissing any UIAlertViews/UIActionSheets when entering background state in iOS 4. This is to avoid any confusion on the user's part when he relaunches the application later. I wonder how I could elegantly dismiss all UIAlertViews at once, without retaining a reference to it everytime I set one up... Any idea ? 回答1: I was intrigued by Dad's answer (funny username :), and curious why it was down-voted. So I tried it. Here is the .m part of a subclass of UIAlertView. Edit:

问题 A UILongPressGestureRecognizer is added to my imageView with action handleLongPressOnPhotos. The most related codes is as following: - (IBAction)handleLongPressOnPhotos:(UILongPressGestureRecognizer *)sender { self.imageWillBeSaved = (UIImageView *)sender.view; //breakPoint1 UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:@"Save the photo" otherButtonTitles: @"Go to the Original photo", nil]; actionSheet

问题 I am using actionsheet, and I have added unicode symbol. But my button title is not centered. I want the unicode symbol to be located at right most. If you think that it is impossible, can I use flag image separately rather than using unicode symbol ? If yes, how could I add image next to the button title? UIActionSheet *actionsheet = [[UIActionSheet alloc] initWithTitle:@"Would you like to see ozone cloud in your area or a trace of your walking/driving/biking activity" delegate:self

问题 I am very new to iOS development and have encountered an error that I just can't seem to find a solution for. I have searched for solutions everywhere, but maybe it is my newness that is preventing me from seeing the problem. The exact warning that is printed in the log is: Attempt to dismiss from view controller <_UIAlertShimPresentingViewController: 0x7aaa4b90> while a presentation or dismiss is in progress! It occurs right after I touch a button on the actionSheet. Here is the code: -

问题 I have an iPhone application that I use the ABPersonViewController and I allow delete. The thing is that the application is a TabBar application and when i use the regular delete method I get this warning: Presenting action sheet clipped by its superview. Some controls might not respond to touches. On iPhone try -[UIActionSheet showFromTabBar:] or -[UIActionSheet showFromToolbar:] instead of -[UIActionSheet showInView:]. the problem is that when I try to press on the "Cancel" of the delete,

问题 I know I have to set the delegate (I did so like this: class ShiftOverview: UITableViewController, UIActionSheetDelegate {... ) but I'm still getting no response when I tap the buttons. It doesn't look like you can set the delegate within the function with UIAlertController either... @IBAction func takeShift(sender: AnyObject) { let myActionSheet = UIAlertController (title: "Confirm", message: "Test message", preferredStyle: UIAlertControllerStyle.ActionSheet) let actionOne = UIAlertAction
