Problem:

You want a simple input dialog to have the user enter a text in iOS.

Solution:

You can use an UIAlertView:

UIAlertView * inputAlert = [[UIAlertView alloc] initWithTitle:@"New Event" message:@"Enter a title for the event" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil];
inputAlert.alertViewStyle = UIAlertViewStylePlainTextInput;
[inputAlert show];

You also need to add the UIAlertViewDelegate protocol to the view controller:

@interface ViewController : UIViewController

And the delegate method when the user taps the Cancel (index 0) or OK (index 1) buttons:

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
    if (buttonIndex == 1)
    {
        NSLog(@"Entered: %@",[[alertView textFieldAtIndex:0] text]);
    }
}
