I verified and it behaves the same for storyboards as it does for xib files. After adding the UIPickerViewto a view, right click it to reveal the delegateand datasourceoutlets. Double check that your UIViewControllerfor the view is a UIPickerViewDataSourceand UIPickerViewDelegate, or you will not be able to attach these outlets unless it is.
我验证了它对于故事板的行为与对于 xib 文件的行为相同。添加UIPickerView到视图后，右键单击它以显示delegate和datasource出口。仔细检查您UIViewController的视图是否为UIPickerViewDataSourceand UIPickerViewDelegate，否则您将无法连接这些插座，除非它是。
