有没有办法让特定国家的大陆？
我正在使用Flurry的API并且它返回一个由国家/地区分隔的JSON，我需要Contintents中的数据，所以我想要一个数组用于其所在国家/地区的每个持续时间，例如：
NSArray * europe = [[NSArray alloc] initWithObjects:@"ES", @"IT", @"FR", ... , nil];
提前致谢！

声明反向查找字典：
NSDictionary *continentForCountries = @{
@"FR": @"Europe",
@"IT": @"Europe",
@"US": @"North America",
@"CA": @"North America",
...
}
然后，您可以使用enumerateObjectsUsingBlock将国家/地区分组到各大洲，在其中您将国家/地区累积到数组字典中，其键是大陆名称：
NSArray *countries = @[...];
NSArray *continentForCountries = @[...];
NSMutableDictionary *countriesByContinents = [NSMutableDictionary new];
[countries enumerateObjectsUsingBlock:^(NSString *country, NSUInteger idx, BOOL *stop) {
NSString *continent = continentForCountries[country];
if (countriesByContinents[continent] == nil)
countriesByContinents[continent] = [NSMutableArray new];
[countriesByContinents[continent] addObject:country];
}];
