Question

My app has a screen where keyboard is always visible. The main element of the screen is a UITextfield. For easy data entering, keyboard is always made visible. When the user finishes entering data and hits Go, the app performs a 4,5 seconds action which is done in the background thread in order to show UIActivityIndicatorView.

My problem is that the Go button on the keyboard still shows as enabled since the logic is performed in the background. The user could potentially hit the Go again causing it to run again.

I am not able to set editable/userinteraction properties to No because then the keyboard disappears. Is there anyway just to disable the Go button or freeze the keyboard until the background thread returns?

Answer 1

You clearly already have a UITextFieldDelegate set up to handle:

- (BOOL)textFieldShouldReturn:(UITextField *)theTextField;

Otherwise, you would not be able to perform accordingly already. Just return NO from that function if the background process is running and the keyboard should not close. Example:

- (BOOL)textFieldShouldReturn:(UITextField *)theTextField {
  if (alreadyPressedGo)
    return NO;
  ...
}

However, this will not “disable” the Go button, simply disable its functionality.
