如何在 ios7 的 UITextfield 中禁用复制/粘贴选项
问题描述：
我试过了
@implementation UITextField (DisableCopyPaste)
-(BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
return NO;
return [super canPerformAction:action withSender:sender];
}
@end
但是它禁用了所有文本字段的复制/粘贴选项，如何禁用特定文本字段的菜单选项.
But it disables all textfield's copy/paste option,how to disable the menu options for specific textfield.
答
我觉得这个方法还行，因为没有做category等，对我来说很好用.
I think this method is ok,since no making of category etc.It works fine for me.
[[NSOperationQueue mainQueue] addOperationWithBlock:^{
[[UIMenuController sharedMenuController] setMenuVisible:NO animated:NO];
}];
return [super canPerformAction:action withSender:sender];
