Deshabilitar copyr, pegar en UITextfield no funciona en iOS 9.x

Creé un campo de text en una class BBCustomUtility.h, files de class .m y luego

+(UITextField*)createTextField: (CGRect)rect image:(NSString*)imageName tag:(int)tag secureText:(BOOL)entry placeh:(NSString*)placeholder { UITextField *transactionField = [ [ UITextField alloc ] initWithFrame: rect ]; transactionField.background = [UIImage imageNamed:imageName]; transactionField.adjustsFontSizeToFitWidth = YES; transactionField.textColor = [UIColor blackColor]; transactionField.font = [UIFont systemFontOfSize:17.0]; transactionField.placeholder = placeholder; transactionField.backgroundColor = [UIColor clearColor]; transactionField.borderStyle = UITextBorderStyleNone; transactionField.autocorrectionType = UITextAutocorrectionTypeNo; transactionField.autocapitalizationType = UITextAutocapitalizationTypeNone; transactionField.textAlignment = UITextAlignmentCenter; transactionField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter; transactionField.keyboardType = UIKeyboardTypeDefault; transactionField.returnKeyType = UIReturnKeyDone; transactionField.tag = tag; transactionField.delegate = self; transactionField.clearButtonMode = UITextFieldViewModeWhileEditing; transactionField.text = @""; [ transactionField setEnabled: YES ]; transactionField.secureTextEntry = entry; return transactionField ; } 

importando de la class común y usado en class1.m

 mPasswordField1 = [BBCustomUtility createTextField:CGRectMake(IS_WIDTH_DEVICE/2-120, 140, 50, 50) image:@"txtField_bg_50.png" tag:1 secureText:YES placeh:[shareObj.mLabelDictionary valueForKey:@""]]; mPasswordField1.keyboardType = UIKeyboardTypeNumberPad; mPasswordField1.clearButtonMode = UITextFieldViewModeNever; mPasswordField1.delegate = self; [self.view addSubview:mPasswordField1]; 

Intenté deshabilitar la opción de pegar copyr en el campo de text en los siguientes methods. Estos no funcionan para mí.

 1) -(BOOL)canPerformAction:(SEL)action withSender:(id)sender { // Returning 'NO' here disables all actions on textfield return NO; } // not working still showing the paste option on textfield 

2)

  -(BOOL)canPerformAction:(SEL)action withSender:(id)sender { if (action == @selector(copy:) || action == @selector(paste:)) { return NO; } return [super canPerformAction:action withSender:sender]; } // this is also not working still showing the paste option 

3)

  -(BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string { if ([mPasswordField1 respondsToSelector:@selector(inputAssistantItem)]) { UITextInputAssistantItem *inputAssistantItem = [mPasswordField1 inputAssistantItem]; inputAssistantItem.leadingBarButtonGroups = @[]; inputAssistantItem.trailingBarButtonGroups = @[]; } } // this also not working 

¿Puede alguien decirme cuál es el error que cometí en mi código?

Agregue el método a continuación en su código y eso es todo,

  - (BOOL)canPerformAction:(SEL)action withSender:(id)sender { [[NSOperationQueue mainQueue] addOperationWithBlock:^{ [[UIMenuController shanetworkingMenuController] setMenuVisible:NO animated:NO]; }]; return [super canPerformAction:action withSender:sender]; } 

Deshabilitará todos los types de edición.

Espero que esto te ayude 🙂

-canPerformAction: withSender: debe estar en una subclass de UITextField. No parece que haya subclasificado porque está asignando un UITextField.
