> In 1.6.0, PhoneGap/Cordova implemented a workaround for an iOS 5.1 bug dealing with local
storage persistence by copying the local storage cache file to a persistent folder. This workaround
results in the local storage file to automatically be backed up to iCloud. Developers may
not want this file backed up to iCloud is certain scenarios (such as device uniqueness), and
there should be an option to not back up to iCloud but yet still maintain persistent integrity
on that device.
> In code, this can be accomplished by the following:
>             // Mark Documents folder with special attribute to tell iOS not to back up
to iCloud.
>             const char* cstr = [documentsDirectory UTF8String] ;
>             const char* attrName = "com.apple.MobileBackup";
>             u_int8_t attrValue = 1;
>             int result = setxattr(cstr, attrName, &attrValue, sizeof(attrValue),
0, 0); // 0 is success, -1 is failure
>             
>             if(result != 0){
>                 NSLog(@"Error: Documents folder could not be set to not backup to iCloud");
>             }
