我试过了
@implementation UITextField (DisableCopyPaste)
-(BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
return NO;
return [super canPerformAction:action withSender:sender];
}
@end
但它禁用所有textfield的复制/粘贴选项,如何禁用特定文本字段的菜单选项.
解决方法
我认为这种方法没问题,因为没有制作类别等.对我来说这很好.
[[NSOperationQueue mainQueue] addOperationWithBlock:^{
[[UIMenuController sharedMenuController] setMenuVisible:NO animated:NO];
}];
return [super canPerformAction:action withSender:sender];
