App got rejected not following the iOS Data Storage Guidelines

Question

My app has downloadable content which I am keeping in Documents Directory. Which gets backed up on iCloud. So instead of setting "Do not backup" of all individual files can I put them under one directory in side Documents and set the "Do not backup" on that directory will that work? or do I have to set the flag on all individual files.

Answer 1

Use below code in your application before saving database to your document directory..

-(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);

//  NSLog(@"Attributs : %d and Path : %@",result,URL);
    if (result != 0) { 

        NSLog(@"File Backup Attribute setting error");

    }

    return result == 0;
}
