问题 Apple's documentation for the UIActionSheet is causing me confusion. First off, in the iPad Human Interface Guidelines, it says : To learn more about using an action sheet in your code, see “Using Popovers to Display Content” in iPad Programming Guide. But then in the "Using Popovers to Display Content" section, it doesn't mention Action Sheets at all! Am I missing something here? http://developer.apple.com/library/ios/#documentation/General/Conceptual/iPadHIG/UIElements/UIElements.html#/

问题 The alertviews in the iOS: Install App OTA: the cancel button is on the LEFT. Delete an App: the cancel button is on the RIGHT. Where the cancel button should be? 回答1: From Human Interface Guideline: In a two-button alert that proposes a potentially risky action, the button that cancels the action should be on the right (and light-colored).

问题 Is it possibe to put an MPVolumeView in a UIAlertView? I have tried to put it inside of it, but it does not display. It may be the sizeToFit or initWithFrame: part? Is there a way of testing if the MPVolumeView is actually being created? Here's the code I initialize both the UIAlertView and MPVolumeView with: UIAlertView *volumeAlert = [[UIAlertView alloc] initWithTitle:@"Volume" message:@"" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; MPVolumeView *volumeView = [

问题 I'm trying to make a UIAlertView shake. I already made the alertView to stay on button click, but the shake animation is not working. Here is what I have: - (void) alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex { if (buttonIndex == 1) { self.direction = 1; self.shakes = 0; [self shake:aUIView]; } } -(void)shake:(UIAlertView *)theOneYouWannaShake { [UIView animateWithDuration:0.03 animations:^ { theOneYouWannaShake.transform = CGAffineTransformMakeTranslation(5

问题 I need to display multiple lines of text in the message of my UIAlertView. I have tried adding a '\n', but it has no effect. It still displays: "This is an examp....". HOWEVER, if I turn my iPhone to landscape mode it displays the message as I intend it to. And then if I switch BACK to portrait mode it displays correctly there as well. Update: After further consideration, I suspect it has something to do with the fact that I am updating the current message with a new (and much longer) string.
