如何让 UILable 响应 IBAction？
我已经自定义了 UITableViewCell （从笔尖加载的静态内容）。该单元格包含一个 UILable，我想在用户点击它时更改其值。 （将显示 PickerView，用户可以从中选择该标签的值）。
所以我创建了以下 IBAction。但是当我尝试将它与 UIlable 连接时，它不允许我这样做。
-(IBAction)selectlanguage:(UILabel *)sender
{
/*
Code to display pickerview and select appropriate language
*/
self.languageLable.text=@"Spanish";
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
appDelegate.userTranslationLanuage = @"en|sp";
}
谁能告诉我我错过了什么？

I have customized UITableViewCell (Static Content Loaded from nib). This cell contains one UILable and I would like to change its value when user taps on it. (PickerView will be displayed and from that user can pick value for that lable).
So I have created following IBAction. But when I tried to connect it with that UIlable it does not allowed me to do so.
-(IBAction)selectlanguage:(UILabel *)sender
{
/*
Code to display pickerview and select appropriate language
*/
self.languageLable.text=@"Spanish";
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
appDelegate.userTranslationLanuage = @"en|sp";
}
Can anyone tell me what I am missing?

只需在连接到此 IBAction 的标签上放置一个不可见的按钮即可。 UILabel 对象并不打算直接响应用户触摸。
Just put an invisible button on the label that's connected to this IBAction. UILabel objects are not intended to respond directly to user touches.
