I need a UIDatePicker for selecting Month and Year only. I checked the class reference documents. Looks like UIDatePicker is a UIView. I imagined UIPickerView may be a sub view and I can hide the component if I can grab it. But no. That was not possible. Do I have to create my own custom picker then? Any ideas?

推荐答案

是的，您可能只想制作自己的选择器.但是，您不必将其子类化或其他任何东西；只需使用通用 UIPickerView 并从您的 UIPickerViewDelegate/UIPickerViewDataSource 方法返回适当的值.

Yeah, you probably want to just make your own picker. You don't have to subclass it or anything, though; just use a generic UIPickerView and return appropriate values from your UIPickerViewDelegate/UIPickerViewDataSource methods.
