ios - 如何为 UIDatePickerView 设置时间间隔？

Question

我将 UIDatePickerView 的时间间隔设置为 30 分钟，并且得到准确的时间间隔。但我的疑问是当我为 UIDatePickerView 设置 minimumDate 时 [NSDate date] 当前时间是 04:25。然后 minimumDate 设置为 04:00。但我想要 04:30。我的代码是

 datePicker.datePickerMode = UIDatePickerModeDateAndTime;
 datePicker.minuteInterval = 30;
datePicker.minimumDate = [NSDate date];
datePicker.maximumDate = [[NSDate date]dateByAddingTimeInterval:32*60*60];

Answer 1

试试这个:

datePicker.datePickerMode = UIDatePickerModeDateAndTime;
datePicker.minuteInterval = 30;
datePicker.minimumDate = [[NSDate date] dateByAddingTimeInterval:30*60];
datePicker.maximumDate = [[NSDate date] dateByAddingTimeInterval:(32*60*60 + 30*60)];
