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!

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 build a custom control from scratch or try to subclass UIDatePicker, but that's not a path I'd recommend.
