我单击按钮，没有任何反应.如果我将inputview从按钮更改为UITextField，则效果很好.有什么想法吗? 谢谢 萨罗

I clickon the button and nothing happens. If I change the inputview from the button to UITextField it works great. Any thoughts? Thanks Saro

推荐答案

inputView属性只是UITextField和UITextView的一部分，而不是UIButton.

The inputView property is only the part of UITextField and UITextView not UIButton.

   @property (readwrite, retain) UIView *inputView;

尽管您可以使用UIButton达到相同的目的.

Although you could achieve the same using UIButton.

创建一个UIButton对象，然后设置一个 action 方法，并将选择器视图添加到UIButton的action方法中的按钮的父视图中.

Create an UIButton object then set an action method and add your picker view in parent view of your button in the action method of UIButton.

应该是这样的.

-(void) buttonClicked:(id) sender
{
    [self.view addSubview:myPickerView];
}
