iOS应用已被拒绝：应用必须遵循iOS数据存储指南，否则将被拒绝

Question

My application got rejected for the 2nd time .

When my app got rejected for the 1st time, I first checked all these links and more:

• iOS App Rejection due to 2.23 - iOS Data Storage Guidelines
• Rejection: "2.23: Apps must follow the iOS Data Storage Guidelines", We do not have any data saved in documents folder
• 2.23: Apps must follow the iOS Data Storage Guidelines or they will be rejected
• http://samwize.com/2013/06/28/ios-data-storage-guidelines-and-how-to-resolve-itunes-connect-reject/
• iOS: Do not back up attribute?

Then, I added a function that marks all my /Documents files with "do not back up" attribute NSURLIsExcludedFromBackupKey . But my application got rejected again. Here is my code:

func excludeUrls(path: String) {
    let urlToExclude = NSURL.fileURLWithPath(path)
    do {
        try urlToExclude.setResourceValue(NSNumber(bool: true), forKey: NSURLIsExcludedFromBackupKey)
        print("\(path) excluded.")
    } catch {
        print("failed to set resource value")
    }
}

More informations:

• I have about 320 static photo embedded in Supporting Files , these images are not backed up.
• I use Google/SignIn , Google/CloudMessaging , Alamofire and SQLite.swift pods
• I have 1 sqlite database that I save in /Library/Cache folder, which is not backed up of course.
• When I check iCloud storage space for my application:

  Go to Settings > iCloud > Storage & Backup > Manage Storage

I found that my app stores ONLY 578 KB

Answer 1

According to the comment you posted, Apple asserts that your app is actually backing up about 6 megabytes of data on launch.

That's the key. Try to reproduce and isolate that behavior. You may be able to use instruments to and a careful eye to figure this out at a lower level, if everything seems to add up otherwise.

The only other thing you can do is ask them to contact you and talk it through with them.

Answer 2

Hopefuly, Apple Review Team finished by accepting my application. Here is what I did:

1 - I moved the generated database to the /Library/Caches

2 - I added an ImageLoader class to optimise the way i'm loading and using images inside the app, specially, there is a lot of images to handle. So, best way is to use cache: check this class

3 - The most important thing that I did, after seeing that my app does not store a lot of KB in iCloud, is that I appealed the rejection and I gave a lot of description and details and even some screenshots.
