... 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;
}
