Hi Please Check Code :

  NSDate *myDate = [NSDate date];
    NSDateFormatter *f = [[NSDateFormatter alloc] init];
    [f setDateStyle:NSDateFormatterLongStyle];
    [f setTimeStyle:NSDateFormatterLongStyle];
    [f setDateFormat:@"dd MMM YYY HH:mm"];

    NSArray *timeZoneNames = [NSTimeZone knownTimeZoneNames];
    for (NSString *name1 in timeZoneNames)
    {
        NSTimeZone *tz = [NSTimeZone timeZoneWithName:name1];
        [f setTimeZone:tz];

        NSLog(@"%@ = \"%@\" = %@", [tz abbreviation], name1, [f stringFromDate:myDate]);
    }

And Output will show :

But I want only one country time and that should be user country. How can I get that? — Himanth, Jul 19 '16 at 09:43
you can get device time zone by using NSTimeZone *currentTimeZone = [NSTimeZone localTimeZone]; — Sagar Shirbhate, Jul 19 '16 at 09:58
By using NSDateFormatter convert date to currentTimeZone which is deviceLocalTimeZone — Sagar Shirbhate, Jul 19 '16 at 09:59
So I have to do like this? NSTimeZone *tz = [NSTimeZone localTimeZone]; [f setTimeZone:tz]; — Himanth, Jul 19 '16 at 10:00

I tried converting INDIAN time to other countries local time.I got the solution

NSString *strDate = @"19-07-2016";
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"dd-MM-yyyy"];
[dateFormat setTimeZone:[NSTimeZone timeZoneWithAbbreviation:@"UTC"]];
NSDate *dateStr = [dateFormat dateFromString:strDate];
NSLog(@"The UTC format date is - %@",dateStr);

[dateFormat setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
[dateFormat setTimeZone:[NSTimeZone systemTimeZone]];
NSString *strLocalDate = [dateFormat stringFromDate:dateStr];
NSLog(@"The Local date is - %@",strLocalDate);

The Printed Result is

The UTC format date is - 2016-07-19 00:00:00 +0000
The Local date is - 2016-07-19 05:30:00

try this....

-(NSString *)getUTCFormateDate:(NSDate *)serverDate
{
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    NSTimeZone *timeZone = [NSTimeZone timeZoneWithName:@"UTC"];
    [dateFormatter setTimeZone:timeZone];
    [dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
    NSString *dateString = [dateFormatter stringFromDate:serverDate];
    return dateString;
}
-(NSString *)getLocalDateTimeFromUTC:(NSString *)strDate
{
    NSDateFormatter *dtFormat = [[NSDateFormatter alloc] init];
    [dtFormat setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
    [dtFormat setTimeZone:[NSTimeZone timeZoneWithAbbreviation:@"UTC"]];
    NSDate *aDate = [dtFormat dateFromString:strDate];

    [dtFormat setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
    [dtFormat setTimeZone:[NSTimeZone systemTimeZone]];

    return [dtFormat stringFromDate:aDate];
}

// Gives Date in UTC
NSDate *currentDate = [[NSDate alloc] init];
// Timezone For India
NSTimeZone *timeZone = [NSTimeZone timeZoneWithName:@"Asia/Kolkata"];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setTimeZone:timeZone];
[dateFormatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"];
NSString *localDateString = [dateFormatter stringFromDate:currentDate];

Firstly, remember two things:

Dates in IOS are "immutable, representing an invariant time interval relative to an absolute reference date (00:00:00 UTC on 1 January 2001)" (ref). Its internal representation is always relative to that UTC point in time regardless of where on earth the device is.
Date formatters default to the user's locale (ref). That means, as long as the user's device has the correct time and time zone in Settings, you don't need to do anything extra to convert the time to the local format and zone.

So, what you should do is convert India to UTC before assigning the value to an NSDate and IOS will take care of the rest.
