Solution

  • Try this it's returning result like

    "(GMT+00:00)Africa/Abidjan"

NSMutableArray *arrResult = [NSMutableArray new];
NSDateFormatter *dateFormatter = [NSDateFormatter new];
NSDate *myDate = [NSDate date];
[dateFormatter setDateStyle:NSDateFormatterLongStyle];
[dateFormatter setTimeStyle:NSDateFormatterLongStyle];
[dateFormatter setDateFormat:@"ZZZ"];
[[NSTimeZone knownTimeZoneNames] enumerateObjectsUsingBlock:^(NSString * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
    NSTimeZone *timeZone = [NSTimeZone timeZoneWithName:obj];
    [dateFormatter setTimeZone:timeZone];
    NSString *dateString = [dateFormatter stringFromDate: myDate];
    NSMutableString *mu = [NSMutableString stringWithString:dateString];
    [mu insertString:@":" atIndex:3];
    NSString *strResult = [NSString stringWithFormat:@"(GMT%@)%@",mu,obj];
    [arrResult addObject:strResult];
}];
NSLog(@"%@", arrResult);
