我已经标记了PickerViews1和2，但我在functitleForRow上收到“不会被执行”的消息，我该如何解决这个问题？@IBOutletweakvarshoeDetailPic:UIImageView!@IBOutletweakvarshoeDetailName:UILabel!@IBOutletweakvarshoeDetailPrice:UILabel!@IBOutletweakvarshoeColourPickerView:UIPickerView!@IBOutletweakvarshoeSizePickerView:UIPickerView!varpickerColo

我的View中有3个选择器，其中一个仅包含图像。因此，对于这个，我必须使用viewForRow，但对于其他2个，它们是带标签的常见选择器，我需要titleForRow，除非我使用viewForRow，titleForRow永远不会被调用。我怎样才能让两个代表都被叫到我的课上？这是我的:-(UIView*)pickerView:(UIPickerView*)thePickerViewviewForRow:(NSInteger)rowforComponent:(NSInteger)componentreusingView:(UIView*)view{[[[objectPickersubvi
