How to move the buttons in a UIAlertView to make room for an inserted UITextField?

Answer 1

Even if you can get this working it's not going to be very iPhone-y. The UIAlertView really is not designed for user input like this. If you look in all the Apple apps you'll see that they use a new view that displayed using the presentModalViewController: method of UIViewController.

Answer 2

Try putting in some (\n)s after the title in the UIAlertView initialization. That will push down the buttons. And I agree with Stephen here. There are chances that Apple might reject an app if it uses controls in a way they shouldn't be. (there's some clause in the Human Interface Guidelines about that!)

Answer 3

Most probably You would want to look into the addTextFieldWithValue method of the UIAlertView? Add the following code somewhere at the top of Your class:

@interface UIAlertView ()
- (void) addTextFieldWithValue: (NSString*) val label: (NSString*) label;
- (UITextField*) textField;
@end

It’s not official, but IMHO it’s not getting You rejected from the App store and it’s much better solution than hacking the textfield into the dialog Yourself.

Answer 4

This simpler method works for me:

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"UIAlertView"
    message:@"<Alert message>" delegate:self cancelButtonTitle:@"OK"
    otherButtonTitles:nil];
[alert addTextFieldWithValue:@"" label:@"Text Field"];

Hope that helps. Oh if you needed multiple button rows then it's:

[alert setNumberOfRows:3];

Cheers

Zoul proposed the best method, to capture user input just do:

a) Add the UITextFieldDelegate protocol to your class.

b) Do something like

    UIAlertView *insertScore = [UIAlertView new];
 [insertScore setDelegate:self];
 [insertScore setTitle:@"New Title!"];
 [insertScore addButtonWithTitle:@"Cancel"];
 [insertScore addButtonWithTitle:@"Ok"];

 insertScore.message = @"\n";

 [insertScore addTextFieldWithValue:@"Input" label:@"player"];

 [[insertScore textField] setDelegate:self];

 [insertScore show]; 

 [insertScore release];

c) The crucial part was to set the delegate of the textField to self, then to access data you can simply:

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex 
{
  NSLog(@"%@",[[alertView textField] text]);
}

Hope this helps someone, since I had to think a bit to get it right.

Answer 7

Explains how to set the number of columns, have not tested it.

However there is a private method, setNumberOfRows:(int)n that will allow you to set a maximum number of rows to display the buttons in. To use this method we need to add our own additions to the UIAlertView class. We do this by adding an @interface for UIAlertView in our .m file.

// extend the UIAlertView class to remove the warning caused
// by calling setNumberOfRows.
@interface UIAlertView (extended)
- (void) setNumberOfRows:(int)num;
@end

This will allow us to call the method without the compiler throwing us a warning.

[myAlert setNumberOfRows:2];
