How to disable copy paste option from UITextField programmatically

This post has many nice solutions: How disable Copy, Cut, Select, Select All in UITextView

My favourite is to override canPerformAction:withSender::

- (BOOL)canPerformAction:(SEL)action withSender:(id)sender{    if (action == @selector(paste:))        return NO;    return [super canPerformAction:action withSender:sender];}

Storyboard users may want to look at this solution, as long as you are ok with subclassing.

I don't think that there is an easy way to achieve this through extensions or protocols.

Swift 3.1

import UIKit@IBDesignableclass CustomTextField: UITextField {    @IBInspectable var isPasteEnabled: Bool = true    @IBInspectable var isSelectEnabled: Bool = true    @IBInspectable var isSelectAllEnabled: Bool = true    @IBInspectable var isCopyEnabled: Bool = true    @IBInspectable var isCutEnabled: Bool = true    @IBInspectable var isDeleteEnabled: Bool = true    override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {        switch action {        case #selector(UIResponderStandardEditActions.paste(_:)) where !isPasteEnabled,             #selector(UIResponderStandardEditActions.select(_:)) where !isSelectEnabled,             #selector(UIResponderStandardEditActions.selectAll(_:)) where !isSelectAllEnabled,             #selector(UIResponderStandardEditActions.copy(_:)) where !isCopyEnabled,             #selector(UIResponderStandardEditActions.cut(_:)) where !isCutEnabled,             #selector(UIResponderStandardEditActions.delete(_:)) where !isDeleteEnabled:            return false        default:            //return true : this is not correct            return super.canPerformAction(action, withSender: sender)        }    }}

Hoping to save a beginner, like myself, some time implementing this...

To implement disabling copy/paste/cut/etc. you must subclass UITextField and override...

- (BOOL)canPerformAction:(SEL)action withSender:(id)sender

To do this...

Create a new class that is a subclass of UITextField (i.e. a new .h and .m files to be included within your app folder). So File->New->"Cocoa Touch Class"->Next->"PasteOnlyUITextField" (for example), subclass of "UITextField"->Next->Create.

Once the .h and .m files are created for our new subclass of UITextField called "PasteOnlyUITextField"...

PasteOnlyUITextField.h

#import <UIKit/UIKit.h>@interface PasteOnlyUITextField : UITextField@end

PasteOnlyUITextField.m

#import "PasteOnlyUITextField.h"@implementation PasteOnlyUITextField/*// Only override drawRect: if you perform custom drawing.// An empty implementation adversely affects performance during animation.- (void)drawRect:(CGRect)rect {    // Drawing code}*/- (BOOL)canPerformAction:(SEL)action withSender:(id)sender{    if (action == @selector(paste:))    {        return true;    }    return false;}@end

Now make sure you import PasteOnlyUITextField.h where you are going to use it, e.g. YourUIViewController.h file...

#import "PasteOnlyUITextField.h"

Now you must use the subclass, either progrommatically or with identity inspector

PasteOnlyUITextField *pasteOnlyUITextField = [[PasteOnlyUITextField alloc] init...];

or...

Select the UITextField and go to the identity inspector, select its class.

You can change the logic associated with the menu options as you see fit...
