在编译时更新Root.Plist

Question

我有一个应用程序设置文件，显示我们的应用程序的版本号。我们的想法是在编译时更新Root.plist，这样我们就不必更新两个地方而不是一个地方。我们更新theBuild设置版本，并希望这些设置在编译时更新Root.plist。

此代码提取生成设置的信息，如何更新Root.plist文件？

NSString *appBuildNo = [[NSBundle mainBundle]objectForInfoDictionaryKey:@"CFBundleShortVersionString"];
NSString *appBuildVersion = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleVersion"];
NSString *appBuildStr = [NSString stringWithFormat:@"%@ Build %@", appBuildNo, appBuildVersion];

NSURL * settingsURL =  [[NSBundle bundleWithURL:[[NSBundle mainBundle] URLForResource:@"Settings" withExtension:@"bundle"]]
                        URLForResource:@"Root" withExtension:@"plist"];
NSDictionary * settingsDict = [NSDictionary dictionaryWithContentsOfURL:settingsURL];
NSArray * settingsArr = [settingsDict objectForKey:@"PreferenceSpecifiers"];
NSUserDefaults * defaults = [NSUserDefaults standardUserDefaults];
for( NSDictionary * setting in settingsArr ){
    NSString * key = [setting objectForKey:@"DefaultValue"];
    [defaults setValue:appBuildStr forKey:key];
    [defaults synchronize];
    break;
}

其想法是默认更新Root.plist，但它不起作用。如能提供任何帮助，将不胜感激。

卓皮帮我解决这个问题很有帮助。设置好设置包和Root.plist文件后，我将以下代码添加到AppDelegate中，并从didFinishLaunchingWithOptions中调用它。

- (void)updateVersionInfo
{
   //This method updates the Root settings to display current Version and Build No in Settings Bundle
   NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
   NSString *appVersionNumber = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"];
   NSString *appBuildNo = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleShortVersionString"];

   NSString *versionNumberInSettings = [NSString stringWithFormat:@"%@ Build %@", appBuildNo, appVersionNumber];

   [defaults setObject:versionNumberInSettings forKey:@"version"];
}

然后，此代码将info.plist文件中版本的内容添加到“我的设置”包中。
