如何自定义UIDatePicker

我需要自定义UIDatePicker因为我们支持各种日期格式，例如
dd-MM-yyyy ， dd-MM-yyyy HH：mm：ss ， dd-MM 。

I need to customize UIDatePicker as we do support a variety of date formats like
dd-MM-yyyy, dd-MM-yyyy HH:mm:ss, dd-MM.

例如在日期和时间选择器模式下，选择器中的年份部分没有滚轮。因此提供的选择器模式是不够的。

E.g. in "date and time" picker mode, there is no roller for year part in picker.Hence the provided picker modes are not sufficient.

有没有办法自定义datepicker为所需的格式。

Is there any way to customize a datepicker for the desired formats.

推荐答案

绝对！
你不能用 UIDatePicker 这样做，因为它只支持4种日期格式，根据 UIDatePicker类参考;但是你可以使用 UIPickerView 。

Absolutely! You cannot do this with UIDatePicker as it only supports 4 date formats, according to the UIDatePicker Class Reference; however you can with a UIPickerView.

您需要实现 UIPickerViewDelegate 方法并为它们提供数据源，就像您使用a UITableView ：

You will need to need to implement UIPickerViewDelegate methods and provide them with a data source, just like you would with a UITableView:

- (NSInteger)numberOfComponentsInPickerView: (UIPickerView*)thePickerView {
   return /* # of columns you need */;
}

- (NSInteger)pickerView:(UIPickerView *)thePickerView numberOfRowsInComponent:(NSInteger)component
{
   return /* # of rows per component */;
}

- (NSString *)pickerView:(UIPickerView *)thePickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
   return /* date source/string/title for the row */;
}
