我知道以前有人问过这个问题，但到目前为止，我发现的帖子都没有解决我的问题。

这是我的代码

NSURL *ubiquitousPackage = [[ubiq URLByAppendingPathComponent:
                                     @"Documents"] URLByAppendingPathComponent: kCloudStorageFileName];

CloudDocument *doc = [[[CloudDocument alloc] initWithFileURL:ubiquitousPackage] autorelease];

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^
{
       NSError* error = [[[NSError alloc] init] autorelease];
       if ([[NSFileManager defaultManager] setUbiquitous: true itemAtURL: [doc fileURL] destinationURL: ubiquitousPackage error: &error])
       {
          NSLog(@"Moved Cloud successfully");
       }
       else
       {
          NSLog(@"Error: %@", error);
       }
});

我收到错误，我不知道如何解决它。希望有人可以帮助我:(

If the file already exists you shouldn't be calling setUbiquitous on it. Use [NSFileManager isUbiquitousItemAtURL:] to determine if it's already in iCloud.
