You can Use this Code . might be it helpful for you.

NSDate sourceDate = Yourdate;

NSTimeZone* sourceTimeZone = [NSTimeZone timeZoneWithName:@"Australia/Melbourne"];

NSTimeZone* destinationTimeZone = [NSTimeZone systemTimeZone]; // your device time . you can also change any time zone like above.

NSInteger sourceGMTOffset = [sourceTimeZone secondsFromGMTForDate:sourceDate];
NSInteger destinationGMTOffset = [destinationTimeZone secondsFromGMTForDate:sourceDate];

NSTimeInterval interval = destinationGMTOffset - sourceGMTOffset;

NSDate* destinationDate = [[NSDate alloc] initWithTimeInterval:interval sinceDate:sourceDate];
