I have created one alarm clock application.
In which, when user clicks on the Set Timer Button, Picker view gets called.
Picker view displays Hours, Mins and Seconds.
When User select them and clicks on Ok, then That Timer Button Value Gets changed.

For Example:
If User Selects 2 Hours , 4 mins and 10 Seconds then

Button Label will be 02:04:10

Now i want to Separate all 3 things like 2 will be stored in one string, 4 will be in other and 10 in some other string.

What should i do here?

Try this think may be helped you ….

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"<your date format goes here"];
NSDate *Yourcurrenttime = [dateFormatter dateFromString:string1];



    NSCalendar *calendar = [NSCalendar currentCalendar];

    NSDateComponents *components = [calendar components:(NSHourCalendarUnit |NSMinuteCalendarUnit | NSSecondCalendarUnit) fromDate: Yourcurrenttime];

    NSInteger hour = [components hour];
    NSInteger minutes = [components minute];
    NSInteger seconds = [components second];

And Store the all value in the string.

NSString *HourSTR =[NSString stringWithFormat:@"%d",hour];
NSString *minutesSTR =[NSString stringWithFormat:@"%d",minutes];
NSString *secondsSTR =[NSString stringWithFormat:@"%d",seconds];
