so

Answer 1

... And finally my application has been approved . just follow this instruction :

put this code on appDelegate.m (didFinishLunching)

NSString *docsDir;
NSArray *dirPaths;
NSURL * finalURL;
dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
docsDir = [dirPaths objectAtIndex:0];


finalURL = [NSURL fileURLWithPath:docsDir];


[self addSkipBackupAttributeToItemAtURL:finalURL];

and skip backup :

- (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;
}
