  • Try this may be help full ... In this you need to pass name of timezone 

     NSTimeZone* sourceTimeZone = [NSTimeZone timeZoneWithName:@"Europe/London"];
NSTimeZone* destinationTimeZone = [NSTimeZone timeZoneWithName:@"America/Mexico_City"];

NSDate *yourDate = [NSDate date]; // Please add here your date that you want change .
//calc time difference
NSInteger sourceGMTOffset = [sourceTimeZone secondsFromGMTForDate:yourDate];

NSInteger destinationGMTOffset = [destinationTimeZone secondsFromGMTForDate:yourDate];
NSTimeInterval interval = destinationGMTOffset - sourceGMTOffset;

//set current real date
NSDate* date = [[NSDate alloc] initWithTimeInterval:interval sinceDate:yourDate];
