我想在用户点击按钮时显示一个选择器我对 UIButton 进行了子类化并更改了它的 inputview 以便它是可写的.
I want to display a picker when the user clicks on a button I subclassed the UIButton and changed its inputview so that it is writable.

我点击按钮，没有任何反应.如果我将 inputview 从按钮更改为 UITextField 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
inputView属性只是UITextField的一部分，UITextView不是UIButton.
The inputView property is only the part of UITextField and UITextView not UIButton.
@property (readwrite, retain) UIView *inputView;
虽然您可以使用 UIButton 实现相同的效果.
Although you could achieve the same using UIButton.
创建一个 UIButton 对象，然后设置一个 action 方法，并在 UIButton 的 action 方法中将您的选择器视图添加到按钮的父视图中.
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];
}
