I'm developing a custom keyboard and based on Apple App Store Review guideline I have to provide a keypad for decimal and number pad :

Keyboard extensions must provide Number and Decimal keyboard types as described in the App Extension Programming Guide or they will be rejected

So I have to provide a keyboard for Decimal and Number Textfield, so how can I detect textfield type.

There is nothing about Number or Decimal Keyboard in App Extension Programming Guide so How detect which textfield I should load Decimal Keyboard or Number Keypad ?

  • What are you asking exactly? The sentence you quoted means that if you're developing a custom keyboard, you should provide a Number and Decimal keyboard. If you're developing an app with text fields, it's up to you to decide which keyboard to bring up on specific text fields. – p4sh4 Oct 10 '14 at 07:04

You can get the current keyboard type before your view appears like so (in Swift). 

   override func viewWillAppear(animated: Bool) {
        super.viewWillAppear(animated)

        // Setup keyboard manager to correct type
        if let inputTraits = self.textDocumentProxy as? UITextInputTraits {
           let keyboardType = inputTraits.keyboardType
           let returnKeyType = inputTraits.returnKeyType
        }
    }

This from my project but reformatted for clarity. I also didn't compile it since it's such a simple example.

I've found it's good not to trust any extension API values until the view is visible or about to appear, but you could also try this in viewDidLoad()
