iPhone UI：每个项目带页脚的下拉选择器

Question

I've done this on android using custom layouts for menus. How do I create a multiline dropdown Picker where each line item has additional string as footer?

Like this:

Answer 1

- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view

You need to implement this delegate method and in it return your custom view.

Apple docs

Answer 2

您可以使用pickerView:viewForRow:forComponent:reusingView:委托方法来实现。
