Question

我真的很喜欢这个。我在我的应用程序中设置了两个UIActionSheets。它们完全正常，直到您使用UIActionSheets中的取消按钮。

当我离开页面时，UIAactionSheet也会返回，它会导致我的应用程序崩溃。

有没有人也有任何想法？

-(IBAction) phoneButtonClicked:(id)sender
{
// open a dialog with just an OK button
phoneActionSheet = [[UIActionSheet alloc] initWithTitle:nil
                                                    delegate:self cancelButtonTitle:@"Cancel" 
                                                    destructiveButtonTitle:nil 
                                                    otherButtonTitles:[NSString stringWithFormat:@"Phone: %@",phone],nil];
phoneActionSheet.actionSheetStyle = UIActionSheetStyleDefault;
[phoneActionSheet showInView:self.view];    // show from our table view (pops up in the middle of the table)
[phoneActionSheet release]; 
}

-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {

if (actionSheet == phoneActionSheet) {

    if(buttonIndex == 0){
            NSString *callPhone = [NSString stringWithFormat:@"tel:%@",phone];
            NSLog(@"Calling: %@", callPhone);
            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:callPhone]];
    }
}

}

我建议不要在phoneButtonClicked中发布phoneActionSheet。我怀疑你可能会尝试用坏指针做某事。另一个好帮助是使用NSZombieEnabled。
