Disable TextFields actions in Swift
Posted By : Akshay Luthra | 08-Jun-2016
Hi, this blog will provide you step by step knowledge on how you can disable the most common actions of a TextField or TextView in Swift iOS apps. The TextFields actions that we will cover in this blog are “select, selectAll, cut, copy, paste, delete”.
First, you need to create a class which extends the UITextField :
import Foundation
import UIKit
class CustomUITextField: UITextField {
override func canPerformAction(action: Selector, withSender sender: AnyObject?) -> Bool {
if action == #selector(NSObject.select(_:)) {
return false
}
if action == #selector(NSObject.selectAll(_:)) {
return false
}
if action == #selector(NSObject.cut(_:)) {
return false
}
if action == #selector(NSObject.copy(_:)) {
return false
}
if action == #selector(NSObject.paste(_:)) {
return false
}
if action == #selector(NSObject.delete(_:)) {
return false
}
return super.canPerformAction(action, withSender: sender)
}
}
Second, wire the storyboard with your ViewController. You need to declare an @IBOutlet :
@IBOutlet var aboutTextField: CustomUITextField?
Third, follow the following steps :
1) Go to your storyboard
2) Click the target TextField
3) Select Identity Inspector
4) Change the class to CustomUITextField
This is all you need to do.
