how to get hour minute from NSDate

Question

Hi in my application i need to get the hour and minute seperately,

NSString *currentHour=[string1 substringWithRange: NSMakeRange(0,2)]; int currentHourInNumber=[currentHour intValue];

consider string1 contains "11:59:13 AM" which is coming from datepicker.

here if i use above code, its okay to get hour if its greaterthan 9. else i need to change NSMakeRange(0,1) to get hour betwee 1 to 9.

is there any methods to get the hour, minutes ..

Thanks in advance.. please provide me sample code

Answer 1

NSDateComponents, All you need can be found here: http://developer.apple.com/mac/library/documentation/cocoa/Conceptual/DatesAndTimes/Articles/dtCalendars.html

Answer 2

Use an NSDateFormatter to convert string1 into an NSDate, then get the required NSDateComponents:

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"<your date format goes here"];
NSDate *date = [dateFormatter dateFromString:string1];
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *components = [calendar components:(kCFCalendarUnitHour | kCFCalendarUnitMinute) fromDate:date];
NSInteger hour = [components hour];
NSInteger minute = [components minute];

I haven't tested it - just typed this into the browser.
