我正在将图像处理到 iCloud 存储。使用 我正在实施的这个链接示例代码。但在这里我使用网格视图来显示图像。对于网格视图，我正在使用AQGridView示例。现在我在实现这个时遇到了一些问题。

我的项目在本地存储中运行良好，但在iCloud存储中无法运行。虽然将图像添加到网格视图中只添加了一个视图，但完成了它从视图中删除的过程，我也没有得到CloudURL。

这里有一些主要代码

    - (void)processiCloudFiles:(NSNotification *)notification {

// Always disable updates while processing results
[_query disableUpdates];

[_iCloudURLs removeAllObjects];

// The query reports all files found, every time.

NSArray * queryResults = [_query results];

for (NSMetadataItem * result in queryResults) {

    NSURL * fileURL = [result valueForAttribute:NSMetadataItemURLKey];

    NSNumber * aBool = nil;

    // Don't include hidden files
    [fileURL getResourceValue:&aBool forKey:NSURLIsHiddenKey error:nil];

    if (aBool && ![aBool boolValue]) {

        [_iCloudURLs addObject:fileURL];

        NSLog(@"%@",_iCloudURLs);



    }

}

NSLog(@"Found %d iCloud files.", _iCloudURLs.count);

_iCloudURLsReady = YES;

if ([self iCloudOn]) {

    NSLog(@"%d",_objects.count);

    // Remove deleted files
    // Iterate backwards because we need to remove items form the array

    for (int i = _objects.count -1; i >= 0; --i) {

        PTKEntry * entry = [_objects objectAtIndex:i];

        if (![_iCloudURLs containsObject:entry.fileURL]) {

            [self removeEntryWithURL:entry.fileURL];
        }
    }

    NSLog(@"%@",_iCloudURLs);

    // Add new files
    for (NSURL * fileURL in _iCloudURLs) {

        [self loadDocAtURL:fileURL];
    }

    self.navigationItem.rightBarButtonItem.enabled = YES;

}

if (_moveLocalToiCloud) {

    _moveLocalToiCloud = NO;
    [self localToiCloudImpl];

}
else if (_copyiCloudToLocal) {

    _copyiCloudToLocal = NO;
    [self iCloudToLocalImpl];

}

[_query enableUpdates];

 }

我还展示了我的应用程序的控制台流程，请帮助我

我对此没有权威的答案，但我肯定会怀疑这是一个时间问题。我希望看到一些委托操作继续了解 iCloud 项目何时上传。

我也会改进你的日志记录。线

NSLog(@"%@",_iCloudURLs);

应该有更好的格式。没有这个，我不能确定，但​​看起来这条线永远都达不到。
