Hello friends I tried the below code to set the start time range and its working fine...

NSDate *todaysDate =[NSDate date];

NSDateComponents *comps = [gregorian components:NSYearCalendarUnit | NSMonthCalendarUnit |  NSDayCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit |NSSecondCalendarUnit fromDate:todaysDate];


[comps setHour:16];
[comps setMinute:00];
[comps setSecond:00];

 NSDate *startDate = [gregorian dateFromComponents:comps];

 NSDateComponents *startcomps = [[NSDateComponents alloc] init];
[startcomps setDay:startDay-weekday];


 self.minDate = [gregorian dateByAddingComponents:startcomps toDate:startDate   options:0];

but when I apply the same code to set the end time range its not working....can any body please help me out in this matter

Ok, I solved your problem (using IB, but I think you could do that programmatically too).

Using IB:

Select your Date picker.
Open Utilities -> Attribute inspector
In block Constraints :
Select Minimum Date and set its value 01/01/1970 16:00:00
Select Maximum Date and set its value 01/01/1970 19:00:00
Set value Date to 01/01/1970 16:00:00
