AppleLanguages也为我提供了语言环境，如果我只想知道语言的话

Question

示例：输出en_GB，需要en。

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSArray *languages = [defaults objectForKey:@"AppleLanguages"];
NSString *currentLanguage = [languages objectAtIndex:0];
NSLog(@"%@", currentLanguage);

Answer 1

NSArray *arrayOfSeperatedString = [currentLanguage componentsSeparatedByString:@"_"];
NSLog(@"%@", [arrayOfSeperatedString objectAtIndex:0]);

编辑：

更好的方法是：

NSLocale *currentLocale = [[[NSLocale alloc] initWithLocaleIdentifier:currentLanguage] autorelease]; //Sets the what laguage the language name and country name should be written in
NSString *displayNameString = [currentLocale displayNameForKey:NSLocaleIdentifier value:currentLocale]; //Sets what language you want written..

NSLog(@"The current language is: %@", displayNameString);

现在，如果当前语言是法语（fr_FR），则返回：

The current language is: français (France)

如果当前语言是英语（en_US），则返回

The current language is: English (United States)

现在，如果您想省略国家/地区名称，请使用componentsSeperatedByString:@" ("，如上所述..
