How Disable Copy, Cut, Select, Select All in Uitextview

How to disable UITextview selection text, copy/paste UIMenuController but still have hyperlinks working [Not duplicate]

just try to create a subclass of UITextView that overrides the canPerformAction:withSender: method

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

How to disable pasting in a TextField in Swift?

I agree with Leonardo Savio Dabus, if I were you I'd use string checking and just give out a warning, it makes things easier. BUT, if disabling paste option is a fancy feature you really want to put into your app, then you need to do more work. I'll provide the steps below.

Step 1: You need to create another class which extends the UITextField. In this example, I made my CustomUITextField.

import Foundation
import UIKit  //Don't forget this

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

Step 2: Wire the storyboard with your ViewController. You need to declare an IBOutlet as in normal case:

@IBOutlet var textFieldA: CustomUITextField?

Wire the circle next to the @IBOutlet to the TextField in the storyboard. THEN, this is important and easy to be ignored:

• Go to your storyboard
• Click the target TextField
• Select Identity Inspector (the 3rd one)
• Change the class to CustomUITextField

Quick snapshot is provided below.

That's it, hope this works.

If you want to know more about the behavior of canPerformAction method, though it's an Objective-C version, the concepts are shared here.

Disable cursor and copy/paste in UITextView (swift)

I think the easy way is to make it with a button instead UITextField

Sorry - this is not for Swift it's for Obj-C but this is the idea:

To do what you want with UITextField you have to subclass the UITextField and try to use this code to disable/hide caret and input (copy/paste)

- (CGRect) caretRectForPosition:(UITextPosition*) position
{
    return CGRectZero;
}

- (NSArray *)selectionRectsForRange:(UITextRange *)range
{
    return nil;
}

- (BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
    if (action == @selector(copy:) || action == @selector(selectAll:) || action == @selector(paste:))
    {
        returnNO;
    }
    return [super canPerformAction:action withSender:sender];
}

Anyway... this is a "functional" example: https://github.com/hackiftekhar/IQDropDownTextField

How control Copy, Paste, Select All, Define in UITextView iPhone app?

First of all if the code you have above isn't working then you probably forgot to change the class of you UITextView to your custom class that implements the method above.

Once you've done that what you've got should work and you should then return no for select all also

   if (action == @selector(selectAll:))
        {
            return NO;
        }

also you may want to return no for cut: also assuming you don't want the user to remove text from the textView.

Also these don't need to be if else statements as they don't depend on each other

They are actually called in this order

cut:
copy:
select:
selectAll:
paste:
delete:

So remove functionality as appropriate.
