iOS8 无法在应用程序组共享容器位置下创建文件夹/文件

Question

我正在使用以下代码在共享目录下创建一个文件夹/文件容器路径。这将有助于应用扩展和包含应用的扩展都可以访问数据。

获取共享容器url位置的代码:

+(NSURL*)getSharedContainerURLPath
{
    NSFileManager *fm = [NSFileManager defaultManager];

    NSString *appGroupName = APP_EXTENSION_GROUP_NAME; /* For example */

    NSURL *groupContainerURL = [fm containerURLForSecurityApplicationGroupIdentifier:appGroupName];

    return groupContainerURL;
}

创建目录的代码

+(void)createDirAtSharedContainerPath
{
    NSString *sharedContainerPathLocation = [[self getSharedContainerURLPath] absoluteString];    
    NSString *directoryToCreate = @"user_abc";
    //basically this is <shared_container_file_path>/user_abc
    NSString *dirPath = [sharedContainerPathLocation stringByAppendingPathComponent:directoryToCreate];

    BOOL isdir;
    NSError *error = nil;

    NSFileManager *mgr = [[NSFileManager alloc]init];

    if (![mgr fileExistsAtPath:dirPath isDirectory:&isdir]) { //create a dir only that does not exists
        if (![mgr createDirectoryAtPath:dirPath withIntermediateDirectories:YES attributes:nil error:&error]) {
                NSLog(@"error while creating dir: %@", error.localizedDescription);                
        } else {
                NSLog(@"dir was created....");
        }
    }
}

上面的代码没有引发任何错误，它表示成功，但我无法在共享容器路径下找到该文件夹​​。任何可能会受到赞赏的想法

我只是通过更改以下代码使我的代码工作

NSString *sharedContainerPathLocation = [[self getSharedContainerURLPath] absoluteString];

到

NSString *sharedContainerPathLocation = [[self getSharedContainerURLPath] path];
