ios如何让自己的应用程序支持系统自带的分享

- (BOOL) application:(UIApplication *)application handleOpenURL:(NSURL *)url {
    NSData *jsonDataImported = [NSData dataWithContentsOfURL:url];
    NSError *error;
    //我这里分享的json文件,打开后就是个Dictionary
    NSDictionary *jsonDictionary = [NSJSONSerialization JSONObjectWithData:jsonDataImported options:NSJSONReadingMutableLeaves error:&error];
    return YES;
}
