Question

I have this code to prompt the UIAlertView, with UITextfield:

UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@"New List Item", @"new_list_dialog")
                                                      message:@"this gets covered" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil];
UITextField *myTextField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 45.0, 260.0, 25.0)];
[myTextField setBackgroundColor:[UIColor whiteColor]];
[myAlertView addSubview:myTextField];
[myAlertView show];
[myAlertView release];

But I would like to add a get the textfield value, after the user click "OK", and after the user click , I want to call a method, how can I assign that to the myAlertView? Thank you.

If you want to add a TextField to an UIAlertView, you can use this property (alertViewStyle) for UIAlertView:

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Title"
                                                message:@"Message"
                                               delegate:self
                                      cancelButtonTitle:@"Done"
                                      otherButtonTitles:nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
[alert show];
[alert release];

and in .h file of it add UIAlertViewDelegate as a protocol and implement the alertView:clickedButtonAtIndex delegate method in the .m file:

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
    NSLog(@"%@", [alertView textFieldAtIndex:0].text);
}

I hope, it works for you!
