iphone - Why was my application still rejected after excluding files from iCloud backup using this code?

Question

I have added the following code to exclude files from iCloud backup, but my application was still rejected:

   - (BOOL)addSkipBackupAttributeToItemAtURL:(NSURL *)URL
{
    if (&NSURLIsExcludedFromBackupKey == nil) { // iOS <= 5.0.1
        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;
    } else { // iOS >= 5.1


        NSLog(@"%d",[URL setResourceValue:[NSNumber numberWithBool:YES] forKey:NSURLIsExcludedFromBackupKey error:nil]);
        return [URL setResourceValue:[NSNumber numberWithBool:YES] forKey:NSURLIsExcludedFromBackupKey error:nil];
    }
}

and I passed the below url in as an NSURL, in the case of the Simulator:

file:///Users/TEST/Library/Application%20Support/iPhone%20Simulator/5.1/Applications/62854BAB-AB51-4771-895F-28C61983A7AC/Documents/MyFolder"

Can any one suggest where my mistake is in this?

Answer 1

Code looks fine to me.

Are you sure that all the files/folders are getting the flags set properly.

You can do that by this terminal command -> ls -al -@
