Question

我的应用程序第二次被拒绝，我失去了3周:(

第一次提交，我排除了只有DIRECTORIES在iCloud中备份。苹果拒绝了......

第二次提交，我排除了DIRECTORIES＆amp;从iCloud备份下载的PICTURES。苹果公司再次拒绝了......苹果公司还抱怨我没有“恢复”＃34;我的应用内购买的功能，而事实上，我确实有一个＆＃34;恢复＆＃34;按钮，它在我测试时起作用了。

我已经完成了Apple的建议，将文件排除在使用NSURLIsExcludedFromBackupKey进行备份。 Macmade在stackoverflow here上发表了一篇有趣的评论：

有时Apple审核人员认为您的数据可以在何时重新生成不是。然后，您必须解释为什么必须备份数据

审稿人多久误解一次，我们必须向他们解释内容是否需要离线和＆amp;不能重新生成？

以下是我用来排除文件和代码的代码。来自iCloud的目录。你发现任何问题吗？

- (BOOL)addSkipBackupAttributeToItemAtURL:(NSURL *)URL

    // There's a chance the download failed, but don't assert here
    //assert([[NSFileManager defaultManager] fileExistsAtPath: [URL path]]);

    NSError *error = nil;
    BOOL success = [URL setResourceValue:[NSNumber numberWithBool:YES]
                                  forKey:NSURLIsExcludedFromBackupKey
                                   error: &error];
    if(!success){
        NSLog(@"Error excluding %@ from backup %@", [URL lastPathComponent], error);

    return success;

我认为诀窍是添加NSURLIsExcludedFromBackupKey或确保目录在文档目录之外。我通过将文档移动到Library / Application Support文件夹（因为它在/ tmp或/ Caches文件夹中没有意义）来完成此操作：

- (void)createNewRefFolder
{
    NSError *error;

    // store in /Library/Application Support/BUNDLE_IDENTIFIER/Reference
    // make sure Application Support folder exists
    NSURL *applicationSupportDirectory = [[NSFileManager defaultManager] URLForDirectory:NSApplicationSupportDirectory
                                                                                inDomain:NSUserDomainMask
                                                                       appropriateForURL:nil
                                                                                  create:YES
                                                                                   error:&error];

    if (error) {
        NSLog(@"KCDM: Could not create application support directory. %@", error);
    }

    NSURL *referenceFolder = [applicationSupportDirectory URLByAppendingPathComponent:@"Reference" isDirectory:YES];
    if (![[NSFileManager defaultManager] createDirectoryAtPath:[referenceFolder path]
                                   withIntermediateDirectories:YES
                                                    attributes:nil
                                                         error:&error]) {
        NSLog(@"KCDM: Error creating Reference folder: %@ ...", error);
    }

    BOOL success = [referenceFolder setResourceValue:@YES forKey: NSURLIsExcludedFromBackupKey error: &error];
    if(!success){
        NSLog(@"KCDM: Error excluding %@ from backup %@", referenceFolder, error);
    }
}

以前的答案很少更新。

您必须检查文件是否存在。否则，您将收到此错误，

Error excluding [FileName] from backup: 
Error Domain=NSCocoaErrorDomain Code=4 "The file “[FileName]” doesn’t exist." 
 ...

我不确定是否应检查值是否已更新。例如如果API重置已经设置了值。如果它试图再次更新文件系统以获得更耗时的设置值，我猜。

更新方法......

+ (BOOL)addSkipBackupAttributeToURLAtPath:(NSURL *)url
{
    if (!url) return NO;
    if (![[NSFileManager defaultManager] fileExistsAtPath:url.path]) return NO;

    NSError *error = nil;
    NSNumber *value = nil;
    BOOL success = [url getResourceValue:&value forKey:NSURLIsExcludedFromBackupKey error:&error];
    if (value.boolValue == YES) return YES;

    success = [url setResourceValue:[NSNumber numberWithBool:YES]
                                  forKey:NSURLIsExcludedFromBackupKey error:&error];
    if(!success){
        NSLog(@"Error excluding %@ from backup: %@", [url lastPathComponent], error);
    }
    return success;
}

+ (BOOL)addSkipBackupAttributeToFileAtPath:(NSString *)path
{
    if (!path) return NO;
    return [self addSkipBackupAttributeToURLAtPath:[NSURL fileURLWithPath:path]];
}

从iCloud备份中排除：NSURLIsExcludedFromBackupKey
