I am making a registration alertview that has a UITextField in it where the user can enter their registration number. everything is pretty much their, however I would like to remove the copy paste function from the textfield programmatically since their is no InterfaceBuilder version of the textfield I have no idea how to do this..

here Is my UIalertview thus far...

- (void)pleaseRegisterDevice {

    UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:@"Please Register Device!" message:@"this gets covered" delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
    regTextField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 45.0, 260.0, 25.0)];
    [regTextField setBackgroundColor:[UIColor whiteColor]];
    regTextField.textAlignment = UITextAlignmentCenter;
    [myAlertView addSubview:regTextField];
    [myAlertView show];
    [myAlertView release];

}

In Swift, If you want your text field to disable all UIResponderStandardEditActions (cut, copy, paste, look up, share, select), use this in UITextFieldDelegate.

func textFieldShouldBeginEditing(_ textField: UITextField) -> Bool {
    textField.isUserInteractionEnabled = false
    return true
}

func textFieldDidEndEditing(_ textField: UITextField) {
    textField.isUserInteractionEnabled = true
}

Swift 5 solution: 

override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
    if action == #selector(UIResponderStandardEditActions.copy(_:)) || action == #selector(UIResponderStandardEditActions.paste(_:)) {
        return false
    }

    return true
}

Disable all actions by UITextField subclass.

import UIKit

class CustomTextField: UITextField {
    override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
        return false
    }
}
