ios - 如何在uitableview中获取这种类型的时区列表？

Question

我正在处理一个应用程序，我必须在 tableview 中显示这种类型的 timezone 列表。

我已经试过了:-

 NSMutableArray *timeZoneArray  = [[NSMutableArray alloc] initWithArray:[NSTimeZone knownTimeZoneNames]];
            NSMutableArray *abbreviationArray = [[NSMutableArray alloc] init];

            for (int count = 0; count < [timeZoneArray count] - 1; count = count + 1) {
                NSString *timeZoneStr = [timeZoneArray objectAtIndex:count];
                [abbreviationArray addObject: [timeZoneStr stringByAppendingFormat:@"(%@)",[[NSTimeZone timeZoneWithName: timeZoneStr] abbreviation]]];
            }
            NSLog(@"Abbreviation : %@",abbreviationArray);

我得到了这种类型的列表

但我想要这种类型的列表

请帮帮我

试试这个，返回结果如下

"(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);
