ios – NSLocalizedString有时会加载字符串,而不是总是

NSLocalizedString只有一半的时间可以恢复所引用键的预期值.其他时候我回到NSLocalizedString中指定的密钥名称,并且在每次运行时都会一直发生.

目前,我目前只支持英语.

我打电话给：

Nsstring *someText = NSLocalizedString(@"mystring.keyname",nil);

en.lproj / Localizable.strings的内容：

"mystring.keyname" = "Hello there!";

当它无法正常工作时,someText的值为mystring.keyname.

以下是我测试可靠性的方法：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    NSBundle *bundle = [NSBundle bundleForClass:[self class]];
    NSLog(@"Strings file: %@",[bundle pathForResource:@"Localizable" ofType:@".strings"]);
    NSLog(@"Localizations: %@",[bundle localizations]);
    NSLog(@"Local Dict: %@",[bundle localizedInfoDictionary]);
    NSLog(@"localizedStringForKey: %@",[bundle localizedStringForKey:@"mystring.keyname"value:@"Wha happened?" table:nil]);
    NSLog(@"Localized String: %@",NSLocalizedString(@"mystring.keyname",@"Are you sure you want to start a new game?"));
}

这会在每次运行时打印出预期值：

Run #1:
Local Dict: (null)
localizedStringForKey: Hello there!
Localized String: Hello there!

Run #2:
Local Dict: (null)
localizedStringForKey: Wha happened?
Localized String: mystring.keyname

我的文件布局如下：

WORKSPACE_DIR/ 
  my_workspace_name.xcworkspace
  PROJECT_DIR/
    - my_project_name.xcodeproj
    RESOURCES_DIR/
      - en.lproj/
          Localizable.strings

XCode的项目级设置：

1) Build Phases has Localizable.strings listed in the "copy Bundle Resources".

2) Build Settings:
   Convert copied Files => YES
   Property List Output Encoding => binary
   Strings file Output Encoding => UTF-16        

3) Info.plist's: CFBundleDevelopmentRegion => 'en'

Localizable.strings配置为UTF-16虽然我没有在文件检查器中看到选中了字符串文件的文本设置选项.但我已经通过在TextWrangler中打开文件来验证编码类型,该文件使用Unix LF将编码显示为Unicode(UTF-16).

关于如何让这个工作一直有效的任何建议？
