刚进入后台的时候消息处理时候我用了本地推送！可以看我前边写的博客，怎么处理刚进入后台接收推送的案例，链接

/**

 注释：打开推送的三种方式：-peter

 1、apns的时候，结束进程退出后台：启动的时候可在 didFinishLaunchingWithOptions的launchOptions中处理；

获取字典 launchOptions 中的 UIApplicationLaunchOptionsRemoteNotificationKey的key

   NSDictionary *optionsRemoteNotificationKey = [launchOptions dictionaryValueForKey:@"UIApplicationLaunchOptionsRemoteNotificationKey"];

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

    /**二次启动获得推送点击信息，本地储存二次启动的内容 仿qq点击推送栏启动 by peter***/

   NSDictionary *optionsRemoteNotificationKey = [launchOptions dictionaryValueForKey:@"UIApplicationLaunchOptionsRemoteNotificationKey"];

    [[NSUserDefaults standardUserDefaults] setObject:optionsRemoteNotificationKey forKey:kSavePushMessage];

    /**为了验证第一次启动的时候不能截获启动信息，加啊alert**/

    /**

    NSString * str = [NSString stringWithFormat:@"%@",launchOptions];

 

    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(5 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{

        UIAlertView *art = [[UIAlertView alloc]initWithTitle:nil message:str delegate:self cancelButtonTitle:@"取消" otherButtonTitles: nil];

        [art show];

 

    });

    **/

    return YES;

}

 2、apns的时候，结束进程未退出后台：启动的时候可在 didReceiveRemoteNotification的userInfo中处理；

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo

{

    NSString *  appData = [userInfo stringValueForKey:@"appData"];

    

    NSData *jsonData = [appData dataUsingEncoding:NSUTF8StringEncoding];

    NSError *err;

    NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:jsonData

                                                        options:NSJSONReadingMutableContainers

                                                          error:&err];

    

    if(err)

    {

        NSLog(@"json解析失败：%@",err);

    }else{

        NSString * positionIdString = [NSString stringWithFormat:@"%@",[dic numberValueForKey:@"positionId"]] ;

        if ([dic numberValueForKey:@"positionId"] !=0) {

            [[NSNotificationCenter defaultCenter] postNotificationName:kString_DispantData object:positionIdString];

        }

    }

}

 3、本地推送，未结束进程未退出后台（此方达为了解决消息刚进入后台时候没有通知的情况）：启动的时候可在 didReceiveLocalNotification的notification中处理；

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification{

    NSDictionary *dic = notification.userInfo;

    NSString * positionIdString = [dic stringValueForKey:@"positionId"];

    if (![positionIdString isEqualToString:@""]) {

        [[NSNotificationCenter defaultCenter] postNotificationName:kString_DispantData object:positionIdString];

    }

 

}

 **/

 

二、处理页面跳转功能

说明：由于情况1都代表app已经结束需要重新启动，只能做本地存储，然后到tabbar页面的时候取出该存储值的对应id然后进行跳转。情况2、3  ，App的tabbar页面已经存在可以注册一个通知在2、3的情况时候发送通知！

1、存储调转

在tabbar的viewDidAppear方法

- (void)viewDidAppear:(BOOL)animated

{

    [super viewDidAppear:animated];

    

    NSDictionary *optionsRemoteNotificationKey = [[NSUserDefaults standardUserDefaults] objectForKey:kSavePushMessage];

    NSString *appDataString = [optionsRemoteNotificationKey stringValueForKey:@"appData"];

    if (appDataString&&![appDataString isEqualToString:@""]) {

        [[NSUserDefaults standardUserDefaults] setObject:nil forKey:kSavePushMessage];

    }

}

2、通知跳转

注册监听tabbar的viewDidLoad方法里边

- (void)viewDidLoad

{

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(pushDispanchPositionDetail:) name:kString_DispantData object:nil];

}

 方法接收

#pragma mark observer Notification

-(void)pushDispanchPositionDetail:(NSNotification *)notify

{

    if (notify.object&&![notify.object isEqualToString:@""]) {

        [self pushData:notify.object];

    }

}

 

- (void)pushData:(NSString *)positionId{

    [self setSelectedIndex:MainTabBarIndex_User];

    RootNavigationController* selNavi = [self.viewControllers objectAtIndex:MainTabBarIndex_User];

    HHPositionDetailC *vc = [[HHPositionDetailC alloc] init];

    vc.positionId = [positionId longLongValue];

    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.25 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{

        selNavi.toolbar.hidden = YES;

        [selNavi pushViewController:vc animated:YES];

        HDMyPositionViewController *myPositionVC = [[HDMyPositionViewController alloc]init];

        NSMutableArray *mutArray = [NSMutableArray arrayWithArray:selNavi.viewControllers];

        [mutArray insertObject:myPositionVC atIndex:1];

        selNavi.viewControllers = [mutArray copy];

    });

}

详细解释跳转代码

    [self setSelectedIndex:MainTabBarIndex_User];

    RootNavigationController* selNavi = [self.viewControllers objectAtIndex:MainTabBarIndex_User];

    HHPositionDetailC *vc = [[HHPositionDetailC alloc] init];

    vc.positionId = [positionId longLongValue];

    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.25 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{

        selNavi.toolbar.hidden = YES;

        [selNavi pushViewController:vc animated:YES];

        HDMyPositionViewController *myPositionVC = [[HDMyPositionViewController alloc]init];

        NSMutableArray *mutArray = [NSMutableArray arrayWithArray:selNavi.viewControllers];

        [mutArray insertObject:myPositionVC atIndex:1];

        selNavi.viewControllers = [mutArray copy];

    });

1、找到所进入的viewController的根导航Navigation；然后进行选中（self代表tabbar）  [self setSelectedIndex:MainTabBarIndex_User];

2、然后延迟调转，由于初始化tababr的原因不延迟跳转会出现调转不进去的情况；所以做延迟跳转处理。

   [selNavi pushViewController:vc animated:YES];

3、找到当前的viewControllers数组，创建需要返回的二级页面加入栈中！

 

这样就能点推送进入C,返回B,在返回所需要的tabbar的某个界面。
