iOS 极光推送在接到消息后跳到，想要的某一页实现办法

#pragma mark  
极光推送在收到消息后，执行的方法

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary
*)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {

    // Required, iOS 7 Support  
获取到的数据

    [JPUSHService
handleRemoteNotification:userInfo];

    _pushDic  = [[NSMutableDictionary
alloc]init];

    NSDictionary *dic= userInfo [@"aps"];

    [_pushDic
setValue:[userInfo
objectForKey:@"_j_msgid"]
forKey:@"_j_msgid"];

    [_pushDic
setValue:userInfo [@"order_number"]
forKey:@"order_number"];

    [_pushDic
setValue:dic[@"alert"]
forKey:@"alert"];

    [_pushDic
setValue:dic[@"badge"]
forKey:@"badge"];

    [_pushDic
setValue:dic[@"sound"]
forKey:@"sound"];

    completionHandler(UIBackgroundFetchResultNewData);

    if ([UIApplication
sharedApplication].applicationState ==
UIApplicationStateActive) {//这是在前台

        [self
creatOrderAlertView];

    }else{//这是在后台

        [self
goToMssageViewControllerWith:_pushDic];

    }

}

#pragma mark  
在前台接到消息后执行的办法

-(void)creatOrderAlertView{

    UIAlertView * alert = [[UIAlertView

                                                     message:@"您有一条新的推送消息!"

                                                    delegate:self

                                           cancelButtonTitle:@"取消"

                                           otherButtonTitles:@"查看",nil];

    [alert show];

}

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{

    [JPUSHService
resetBadge];

    if (buttonIndex==1) {

        [self
goToMssageViewControllerWith:_pushDic];

#pragma mark   通过我下面的函数可以获取当前的controller

- (UIViewController*)topViewController{

    return [self
topViewControllerWithRootViewController:self.window.rootViewController];

}

- (UIViewController*)topViewControllerWithRootViewController:(UIViewController*)rootViewController{

    if ([rootViewController
isKindOfClass:[UITabBarController
class]]) {

        UITabBarController *tabBarController = (UITabBarController *)rootViewController;

        return [self
topViewControllerWithRootViewController:tabBarController.selectedViewController];

    } else
if ([rootViewController
isKindOfClass:[UINavigationController
class]]) {

        UINavigationController* navigationController = (UINavigationController*)rootViewController;

        return [self
topViewControllerWithRootViewController:navigationController.visibleViewController];

    } else
if (rootViewController.presentedViewController) {

        UIViewController* presentedViewController = rootViewController.presentedViewController;

        return [self
topViewControllerWithRootViewController:presentedViewController];

    } else {

        return rootViewController;

    }

}
