My suggestion is to look at Apple Documentation for NSTimeZone.

If you do, you became aware that there is a method -secondsFromGMT that returns seconds form the Greenwich time.
Maybe you can also create your own date formatter string to pass as -dateFormat property of an NSDateFormatter and get directly a string representation of time zone. Something like that @"ZZZZZ".

Creating a date formatter that only returns the offset from GMT sounds like the correct solution. (voted.) That way you don't have to worry about fussy formatting issues. The date formatter would do it for you. – Duncan C Jan 20 '16 at 13:53

Try this:

    NSDate *myDate = [NSDate date];
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setDateStyle:NSDateFormatterLongStyle];
    [dateFormatter setTimeStyle:NSDateFormatterLongStyle];
    [dateFormatter setDateFormat:@"ZZZ"];

     NSTimeZone *timeZone = [NSTimeZone timeZoneWithName: @"Asia/Kolkata"];
    [dateFormatter setTimeZone:timeZone];

    NSString *dateString = [dateFormatter stringFromDate: myDate];
    NSLog(@"%@", dateString);

OUTPUT:

+0530

-(void)getCurrentTimeZoneMins
{
    NSTimeZone* destinationTimeZone = [NSTimeZone systemTimeZone];
    float timeZoneOffset = [destinationTimeZone secondsFromGMTForDate:[NSDate date]] / 60;;
    NSLog(@"%f mins",timeZoneOffset);
}

-(void)printTimeZone
{
    NSDateFormatter *localTimeZoneFormatter = [NSDateFormatter new];
    localTimeZoneFormatter.timeZone = [NSTimeZone localTimeZone];
    localTimeZoneFormatter.dateFormat = @"Z";
    NSString *localTimeZoneOffset = [localTimeZoneFormatter stringFromDate:[NSDate date]];
    NSLog(@"%@",localTimeZoneOffset);
}
