UITextField 禁用剪切板

新建一个类继承UITextField，然后实现canPerformAction方法： .h #import <UIKit/UIKit.h> @interface NoCopyTextField : UITextField @end .m #import "NoCopyTextField.h"

@implementation NoCopyTextField

• (id)initWithFrame:(CGRect)frame { self = [super initWithFrame:frame]; if (self) { // Initialization code } return self; }

• (BOOL)canPerformAction:(SEL)action withSender:(id)sender { UIMenuController *menuController = [UIMenuController sharedMenuController]; if (menuController) { [UIMenuController sharedMenuController].menuVisible = NO; } return NO; }

用hook机制对canPerformAction 检测就好了, 很简单
