How to get all the textfields from a view in swift

Question

I have a view which has more than 15 UITextFields. I have to set bottomBorder(extension) for all the UITextFields. I can set it one by one for all

Answer 1

extension:

extension UIView {
    func viewOfType<T:UIView>(type:T.Type, process: (_ view:T) -> Void)
    {        
        if let view = self as? T
        {
            process(view)
        }
        else {
            for subView in subviews
            {
                subView.viewOfType(type:type, process:process)
            }
        }
    }
}

Usage:

view.viewOfType(type:UITextField.self) {
        view in

        view.text = "123"
}

Answer 2

This worked for me.

var textFieldsArray = [UITextField]()

for view in self.view.subviews {
    if view is UITextField {
        textFieldsArray.append(view as! UITextField)
    }
}

textFieldsArray.forEach { $0.setBottomBorder() }

If you want to get the result of the function applied in a new array, use map() instead.
