Unable to add UITextField to UIAlertView on iOS7...works in iOS 6

Question

The code below works on iOS6 (and before) but the UITextField does not display in iOS7...any ideas on how to get a UITextField to display in an UIAlterView in iOS7?

UIAlertView* dialog = [[UIAlertView alloc] init]; [dialog setDelegate:self]; [dialog setTitle:@"Enter ESC Score"]; [dialog setMessage:@" "]; [dialog addButtonWithTitle:@"Cancel"]; [dialog addButtonWithTitle:@"OK"]; dialog.tag = 5;  nameField = [[UITextField alloc] initWithFrame:CGRectMake(20.0, 45.0, 245.0, 25.0)]; [nameField setKeyboardType:UIKeyboardTypeNumberPad]; [nameField becomeFirstResponder]; [nameField setBackgroundColor:[UIColor whiteColor]]; [dialog addSubview:nameField]; CGAffineTransform moveUp = CGAffineTransformMakeTranslation(0.0, 0.0); [dialog setTransform: moveUp]; [dialog show]; [dialog release];  [nameField release]; 

Code run for iOS6 displays this:

same code in iOS7 displays this (notice how UITextField is missing and there is no keyboard):

You can't easily alter the view hierarchy of a UIAlertView in iOS 7. (Nor should you; the documentation specifically tells you not to.) Head over to the developer forums to see a long discussion about it.

One alternative in your case is to set alert.alertViewStyle = UIAlertViewStylePlainTextInput; This will add a text field for you. You can access it in the UIAlertView delegate callback by using UITextField *textField = [alertView textFieldAtIndex:0];.
