I think this is a problem with the new San Francisco font (a font larger than Helvetica) and the .xib file. It can be hacked by changing the UIDatePicker mode right before displaying it, and then changing it to the desired one:
[myDatePicker setDatePickerMode:UIDatePickerModeDateAndTime]; [myDatePicker setDatePickerMode:UIDatePickerModeDate];
Also try adding DatePicker programmatically.
I think this is a bug in iOS 9 with a new font.
