Prevent custom keyboard in textfield

Question

I was experimenting with how a custom keyboard affects my app. I installed Swype on my iPhone 6.

I find that in some of my views where I have custom inputView property set on a text field, the Swype keyboard is overriding and presenting instead of my picker. This completely breaks my UI and cannot be allowed.

Is there a way to explicitly tell iOS 8 only to use the inputView I have set?

Is this a bug, perhaps? It is not at all expected behavior to allow a third party to override my input spec?

Answer 1

You can disable custom keyboard for your app with the following code:

include this in your app delegate:

- (BOOL)application:(UIApplication *)application shouldAllowExtensionPointIdentifier:(NSString *)extensionPointIdentifier {
    if ([extensionPointIdentifier isEqualToString: UIApplicationKeyboardExtensionPointIdentifier]) {
        return NO;
    }
    return YES;
}

Answer 2

Swift 4

  func application(_ application: UIApplication, shouldAllowExtensionPointIdentifier extensionPointIdentifier: UIApplicationExtensionPointIdentifier) -> Bool {
        if (extensionPointIdentifier == .keyboard) {
            return false
        }
        return true
    }
