UIDatePicker返回值数据类型问题
我想从设置如下的 UIDatePicker 传回数据：
UIDatePicker *pickerView = [[UIDatePicker alloc] init];
pickerView.datePickerMode = UIDatePickerModeCountDownTimer;
选择器模式设置为倒计时器。我需要将什么类型的数据类型传回委托？
我以为它会像 pickerView.value 但我没有看到它。我是否需要获取 pickerView.date 并将其转换为 NSNumber 或其他内容？
我只想根据从 UIDatePicker 返回的值设置一个计时器...
I want to pass back data from a UIDatePicker that is setup like this:
UIDatePicker *pickerView = [[UIDatePicker alloc] init];
pickerView.datePickerMode = UIDatePickerModeCountDownTimer;
The picker mode is set to be the count down timer. What type of data type do I need to pass back to the delegate?
I was thinking it would be something like pickerView.value But I am not seeing it. Do I need to get the pickerView.date and cast it as an NSNumber or something?
I just want to setup a timer based on the value I am getting back from the UIDatePicker...

使用pickerView.countDownDuration，它返回一个NSTimeInterval（双精度）。
Use
pickerView.countDownDuration, which returns an NSTimeInterval (a double).
