Want to achieve the Keyboard selection through @IBInspectable

Question

I wanted to create a keyboard selection from @IBInspectabale

How to achieve this

I am creating a view, In which I insert an ImageView and a TextField, Now I am creating this custom view class as @IBDesignable and created the @IBInspectable elements.

I successfully create side image and placeholder elements but now I am trying to create the keyboard type but facing issues.

code snipped : `import UIKit

@IBDesignable class CustomTextField: UIView,UITextFieldDelegate {

//custom view from the XIB file
var view: UIView!

@IBOutlet weak var textField: UITextField!
@IBOutlet weak var imageView: UIImageView!

override init(frame: CGRect) {
    super.init(frame: frame)
    loadViewFromNib ()
}

required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
    loadViewFromNib ()
}

func loadViewFromNib() {
    let bundle = Bundle(for: type(of: self))
    let nib = UINib(nibName: "CustomTextField", bundle: bundle)
    let view = nib.instantiate(withOwner: self, options: nil)[0] as! UIView
    view.frame = bounds
    view.autoresizingMask = [.flexibleWidth, .flexibleHeight]
    self.addSubview(view);



}

@IBInspectable var sideImage: UIImage? {
    get {
        return imageView.image
    }
    set(sideImage) {
        imageView.image = sideImage
    }
}

@IBInspectable var placeHolderText: String? {
    get {
        return textField.placeholder
    }
    set(placeHolderText) {
        textField.placeholder = placeHolderText
    }
}'

all the above working fine, but following is not working for me:

@IBInspectable var keyboard: UIKeyboardType? {
    get{
        return UIKeyboardType(rawValue: textField.keyboardType.rawValue)
    }
    set(keyboard){
        textField.keyboardType = keyboard!
    }
}

}

I tried it by creating enum but it does not give any result for me.

First of all thanks to everyone. My problem is solved without doing any extra effort of creating enum and all. I used the apple predefined UIKeyboardType enum. Just write the following code:

@IBInspectable var keyboard:Int{
    get{
        return self.textField.keyboardType.rawValue
    }
    set(keyboardIndex){
        self.textField.keyboardType = UIKeyboardType.init(rawValue: keyboardIndex)!

    }
}

And it will show the Keyboard in Interface builder, and you can set 0,1,2... value for your keyboard type. where the 0,1,2 represent as follows:

0: default // Default type for the current input method.

1: asciiCapable // Displays a keyboard which can enter ASCII characters

2: numbersAndPunctuation // Numbers and assorted punctuation.

3: URL // A type optimized for URL entry (shows . / .com prominently).

4: numberPad // A number pad with locale-appropriate digits (0-9, ۰-۹, ०-९, etc.). Suitable for PIN entry.

5: phonePad // A phone pad (1-9, *, 0, #, with letters under the numbers).

6: namePhonePad // A type optimized for entering a person's name or phone number.

7: emailAddress // A type optimized for multiple email address entry (shows space @ . prominently).

8: decimalPad // A number pad with a decimal point.

9: twitter // A type optimized for twitter text entry (easy access to @ #)

It is not possible to use enum types for @IBInspectable vars. You have to set your var as a String or Int.

From Apple's docs:

You can attach the IBInspectable attribute to any property in a class declaration, class extension, or category for any type that’s supported by the Interface Builder defined runtime attributes: boolean, integer or floating point number, string, localized string, rectangle, point, size, color, range, and nil.
