It is possible to show keyboard without using UITextField and UITextView iphone app?

Question

I am working in iPhone messaging based app.

I want to show keyboard with keyboard inputAccessoryView in keyboard without using UITextView and

Answer 1

See the documentation for doing that here:

Simple Text Input

All you need to do is have your view implement UIKeyInput and call [inputView becomeFirstResponder] when the view is touched. Your view also needs to implement canBecomeFirstResponder and return YES.

Sample code from the iOS documentation which does this.

Answer 2

Make a View, Label or what ever to conform to UIKeyInput. In this case a UIView

Sub class a UIView:

import UIKit

class KeyInputView: UIView {
   var _inputView: UIView?

   override var canBecomeFirstResponder: Bool { return true }
   override var canResignFirstResponder: Bool { return true }

   override var inputView: UIView? {
       set { _inputView = newValue }
       get { return _inputView }
   }
}

// MARK: - UIKeyInput
//Modify if need more functionality
extension KeyInputView: UIKeyInput {
    var hasText: Bool { return false }
    func insertText(_ text: String) {}
    func deleteBackward() {}
}

Setup your View, in this case with a picker (in viewDidLoad or where ever)

let languangePicker = UIPickerView()
languangePicker.dataSource = self
languangePicker.delegate = self
keyInputView.inputView = languangePicker

To show:

keyInputView.becomeFirstResponder()

To hide:

keyInputView.resignFirstResponder()

Set picker data, from datasource (compiler force u to do it)

Grab data picker events from delegate

You can try the answers on these other SO posts:

• Use the system keyboard without a UITextView or UITextField

• iphone keyboard without textview

You can also try this:

UIKeyboard *keyboard = [[[UIKeyboard alloc] initWithFrame: CGRectMake(0.0f,          contentRect.size.height - 216.0f, contentRect.size.width, 216.0f)] autorelease];
[keyboard setReturnKeyEnabled:NO];
[keyboard setTapDelegate:editingTextView];
[inputView addSubview:keyboard];

Answer 4

In xcode simulator:

Sometimes the keyboard wont show because the software keyboard is off. Go to hardware -> Keyboard -> toggle keyboard

Answer 5

I have made a small utility file that can call a Keyboard with a textfield on a button touch !

Answer 6

For anyone, who wants to show keyboard without UITextField/UITextView for some reasons, could easily extend some view, which requires text input by implementing UIKeyInput protocol and canBecomeFirstResponder method.
