iOS - 我可以修改 iPhone 中的实时属性列表文件吗？

发布于 2024-10-31 13:58:47 字数 152 浏览 3 评论 0原文

我有一个属性列表文件，当我构建程序时，该文件会进入捆绑包。现在，我想用我的 Mac 修改它，并在我的程序运行时更新它。我想捆绑文件不是正确的方法，因为在构建后我似乎无法访问捆绑包的内容。

我应该如何接近？至少使用 iPhone 模拟器工作会很不错，但使用设备工作也会非常好。

您的应用程序包已签名，因此在创建/签名后无法对其进行修改。
为了修改 plist，您需要首先将其复制到应用程序的 Documents 目录中。然后您可以修改副本。这是我在我的一个应用程序中使用的一种方法，该方法在应用程序启动期间将名为FavoriteUsers.plist 的文件从捆绑包复制到文档目录。

    /* Copies the FavoritesUsers.plist file to the Documents directory
     * if the file hasn't already been copied there
     */
    + (void)moveFavoritesToDocumentsDir
    {
        /* get the path to save the favorites */
        NSString *favoritesPath = [self favoritesPath];

        /* check to see if there is already a file saved at the favoritesPath
         * if not, copy the default FavoriteUsers.plist to the favoritesPath
         */
        NSFileManager *fileManager = [NSFileManager defaultManager];
        if(![fileManager fileExistsAtPath:favoritesPath])
        {
        NSString *path = [[NSBundle mainBundle] pathForResource:@"FavoriteUsers" ofType:@"plist"];
        NSArray *favoriteUsersArray = [NSArray arrayWithContentsOfFile:path];
        [favoriteUsersArray writeToFile:favoritesPath atomically:YES];
        }
    }

    /* Returns the string representation of the path to
     * the FavoriteUsers.plist file
     */
    + (NSString *)favoritesPath
    {
        /* get the path for the Documents directory */
        NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *documentsPath = [paths objectAtIndex:0];

        /* append the path component for the FavoriteUsers.plist */
        NSString *favoritesPath = [documentsPath stringByAppendingPathComponent:@"FavoriteUsers.plist"];
        return favoritesPath;
    }

Your application bundle is signed, so it can not be modified after it is created/signed.
In order to modify the plist, you need to copy it to the Documents directory for your application first. You can then modify the copy. Here is a method that I have in one of my apps that copies a file called FavoriteUsers.plist from the bundle to the documents directory during app start up.

    /* Copies the FavoritesUsers.plist file to the Documents directory
     * if the file hasn't already been copied there
     */
    + (void)moveFavoritesToDocumentsDir
    {
        /* get the path to save the favorites */
        NSString *favoritesPath = [self favoritesPath];

        /* check to see if there is already a file saved at the favoritesPath
         * if not, copy the default FavoriteUsers.plist to the favoritesPath
         */
        NSFileManager *fileManager = [NSFileManager defaultManager];
        if(![fileManager fileExistsAtPath:favoritesPath])
        {
        NSString *path = [[NSBundle mainBundle] pathForResource:@"FavoriteUsers" ofType:@"plist"];
        NSArray *favoriteUsersArray = [NSArray arrayWithContentsOfFile:path];
        [favoriteUsersArray writeToFile:favoritesPath atomically:YES];
        }
    }

    /* Returns the string representation of the path to
     * the FavoriteUsers.plist file
     */
    + (NSString *)favoritesPath
    {
        /* get the path for the Documents directory */
        NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *documentsPath = [paths objectAtIndex:0];

        /* append the path component for the FavoriteUsers.plist */
        NSString *favoritesPath = [documentsPath stringByAppendingPathComponent:@"FavoriteUsers.plist"];
        return favoritesPath;
    }
