蘋果第二次拒絕了我的應用

Question

我創建了一個應用程序，但蘋果兩次拒絕接受不遵循ios數據存儲准則的信息，我感到驚訝，因為我已經提交了應用程序而沒有任何問題，我正在使用sqlite來存儲我的數據，並且正在將圖像存儲到文檔目錄及其路徑中進入數據庫，我已經做了

- (BOOL)addSkipBackupAttributeToItemAtURL:(NSURL *)URL
{
    const char* filePath = [[URL path] fileSystemRepresentation];

    const char* attrName = "com.apple.MobileBackup";
    u_int8_t attrValue = 1;

    int result = setxattr(filePath, attrName, &attrValue, sizeof(attrValue), 0, 0);
    return result == 0;
}

-(void) copyDatabaseIfNeeded {

    //Using NSFileManager we can perform many file system operations.
    NSFileManager *fileManager = [NSFileManager defaultManager];
    NSError *error;
    NSString *dbPath = [self getDBPath];
    BOOL success = [fileManager fileExistsAtPath:dbPath];

    if(!success) {
        NSString *defaultDBPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:databaseName];
        success = [fileManager copyItemAtPath:defaultDBPath toPath:dbPath error:&error];

        [self addSkipBackupAttributeToItemAtURL:[NSURL URLWithString:dbPath]];

        if (!success)
            NSAssert1(0, @"Failed to create writable database file with message '%@'.", [error localizedDescription]);
    }
}

-(void)connectWithDB
{
    [self copyDatabaseIfNeeded];
    [self generateDB];
}

在我的booldidfinishWithLaunchingOption函數中

[self connectWithDB];

我不知道為什么會有問題

We found that your app does not follow the iOS Data Storage Guidelines, which is required per the App Store Review Guidelines.

In particular, we found that on launch and/or content download, your app stores 2.5 MB. To check how much data your app is storing:

Install and launch your app
Go to Settings > iCloud > Storage & Backup > Manage Storage
If necessary, tap "Show all apps"
Check your app's storage

您使用的是舊方法。 使用本文檔中描述的更新方法

- (BOOL)addSkipBackupAttributeToItemAtURL:(NSURL *)URL
{
    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;
}
