I have 2:01:20 PM format in one label; after some calculations, I need to change the hour and/or minute of that label.
That is ,Is it possible to change that label value, by converting it as NSDate object and modifying hour and minute like 3:20:30 PM?
Are there any setter methods for this?
If you need to calculate specific real instances in time e.g. 3:20:30 PM Oct 23, 2010, then you want to use NSCalendar which lets you decompose dates and do date related calculations.
Word of warning. Date and time calculations are surprisingly complex and detailed. Expect to spend a couple of hours learning the API.
