UIDatePicker hours interval (NSCalendarUnit?)
问题 I'm trying to make a UIDatePicker wich is alowing to select hours only betwen 6.00 and 17.00. The other hours shall be inactive but still visible. I think it can be done with setting up the picker calendar and then use this: - (NSRange)maximumRangeOfUnit:(NSCalendarUnit)unit but i'm nou sure how. Maybe someone can help me. Thank you! 回答1: Sorry, but UIDatePicker doesn't support setting valid time ranges like you describe. The only options are minimum and maximum dates. You'll either need to
