Custom TextField change settings at the time of creation

Question

I want all of TextField to have small letters.and if I need to change to a larger one I could write inside the creation.But my code doesn't work, what am I doing wrong?

class ViewController: UIViewController

 private let TextField: CustomTextField = { //LETTERS (no work)
        let textfield = CustomTextField() 
        textfield.autocapitalizationType = .allCharacters 
        return textfield
    }()
private let TextField2: CustomTextField = { //letters (work)
    let textfield = CustomTextField() 
    return textfield
}()


  

class CustomTextField: UITextField

override func layoutSubviews() {
    super.layoutSubviews() 
    self.autocapitalizationType = .none 
}

Answer 1

layoutSubviews() function is called after the initialization of your textFields. If you debug your code, you will see that TextField.autocapitalizationType will be set to .allCharacters . But after initialization of your object, layoutSubviews() will be called and autocapitalizationType will be set to .none . So you need to define the self.autocapitalizationType =.none inside init of your CustomTextField .

Answer 2

First, remove the override of layoutSubviews() - as mentioned by Muhammed's answer, setting the autocapitalizationType here will overwrite your custom value as soon as layoutSubviews() is called.

Then, if you give your CustomTextField a custom initializer with a parameter for the capitalization type like this:

init(autocapitalizationType: UITextAutocapitalizationType = .none) {
    super.init(frame: .zero)
    self.autocapitalizationType = autocapitalizationType
}

required init?(coder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
}

Then you can just initialize it all in one step like this, no closure required:

private let textField = CustomTextField(autocapitalizationType: .allCharacters)

If you don't want to set a type then you can leave the CustomTextField() parentheses empty since the initializer adds .none as a default.
