iOS推送详解(二)收到通知跳到指定页面的处理办法

接着上一篇继续，当接到通知需要的操作

一、APP在前台

实现效果，在前台无论在那个页面都在顶部展示一个横条，显示推送信息，点击时跳到自己处理的页面(10秒不点击自动移除这个横条view)

直接上代码吧，讲解一下思路，有问题留言

当接到通知，创建一个view放在window上并携带通知的信息，在加一个同样大小的control添加点击事件，点击执行我们需要操作的事项和跳转相应页面，方法如下

       //应用在前台或者后台开启。
    if (application.applicationState == UIApplicationStateActive ||application.applicationState == UIApplicationStateBackground){

        self.notifyView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 64, KscreenWidth, 44)];

        self.notifyView.tag = 10001;

        _notifyView.image = [UIImage imageNamed:@"返回条.jpg"];
        _notifyView.userInteractionEnabled = YES;
        UIImageView *goImView = [[UIImageView alloc] initWithFrame:CGRectMake(KscreenWidth-26, 13, 11, 18)];
        goImView.image = [UIImage imageNamed:@"箭头"];
        [_notifyView addSubview:goImView];

        UILabel *lable = [[UILabel alloc] initWithFrame:CGRectMake(8, 12, KscreenWidth, 21)];
        lable.textAlignment = NSTextAlignmentLeft;
        NSString *alertStr = userInfo[@"aps"][@"alert"];
        if (alertStr.length > 20) {
            NSString *subString = [alertStr substringToIndex:19];
            alertStr = [subString stringByAppendingString:@"..."];
        }
        lable.text = alertStr;
        lable.font = [UIFont systemFontOfSize:14.0f];
        [_notifyView addSubview:lable];

        UIControl *control = [[UIControl alloc] initWithFrame:CGRectMake(0, 0, KscreenWidth, 44)];
        [control addTarget:self action:@selector(skipViewC) forControlEvents:UIControlEventTouchUpInside];
        [_notifyView addSubview:control];

         [[UIApplication sharedApplication] windows][0].hidden = NO;
        UIViewController *viewVC = [UIApplication sharedApplication].keyWindow.rootViewController;
        [[UIApplication sharedApplication].keyWindow addSubview:_notifyView];

        [NSTimer scheduledTimerWithTimeInterval:10.0 target:self selector:@selector(removeALarmView) userInfo:nil repeats:NO];

二、APP在后台

上面直接else一下调用 [self skipViewC]上面control点击事件即可。看实现方法

这里if里的是，直接返回了需要的数据或者不需要返回数据只需要跳转页面的实现方式，将APP启动方法里的启动页声明为全局，在这里直接使用跳转到相应页面

else里的是，由于展示详情页需要展示好多内容所以返回一个id 在通过id 查询信息展示跳转

       - (void)skipViewC{

    _launcher.selectedIndex = 0;

    [self removeALarmView];

    NSString *msgId = _userInfoDic[@"formid"];

    if ([msgId isEqualToString:@"todo"]) {

        TaskListViewController *taskListView = [[TaskListViewController alloc] init];
        taskListView.title = @"待办事项";
        taskListView.isPush = @"yes";

        if ([_isLogin isEqualToString:@"no"]) {
            _launcher = [self.navigationController.viewControllers objectAtIndex:1];
        }else{
            _launcher = [self.navigationController.viewControllers objectAtIndex:0];
        }
        _launcher.selectedIndex = 1;
        XNavigationController *currentVC = (XNavigationController *) _launcher.selectedViewController;

        [currentVC pushViewController:taskListView animated:YES];
//        taskListView doQuery:@"" and:0];
//        [self.navigationController pushViewController:taskListView animated:YES];

//        [taskListView doQuery:@"" and:0];
    }else{


        //请求获取到msgAcceptPush 对象在跳转
        NSString *svcUrl = [[AppConfig sharedInstance] urlStringOfAction:@"Msg_detailmsg"];

        NSString *urlString = [svcUrl stringByAppendingString:[NSString stringWithFormat:@"?userId=%@&sendId=%@",[AppConfig sharedInstance].userId,msgId]];
        GTMHTTPFetcher *fetcher = [GTMHTTPFetcher fetcherWithURLString:urlString];

        [fetcher beginFetchWithCompletionHandler:^(NSData *data, NSError *error) {
            if (!error) {
                NSDictionary *dict = [NSDictionary dictionaryWithXMLData:data];
                id msgPushs = [dict valueForKey:@"msg"];

                MsgAcceptPush *msgAcceptPush = [[MsgAcceptPush alloc] initWithDict:msgPushs];

                MsgDetailTableViewController *msgDetailView = [[MsgDetailTableViewController alloc] init];
                msgDetailView.title = @"通知详情";
                msgDetailView.msgId = msgAcceptPush.mid;
                msgDetailView.msgType = @"accept";
                msgDetailView.msgAcceptPush = msgAcceptPush;

                if ([_isLogin isEqualToString:@"no"]) {
                    _launcher = [self.navigationController.viewControllers objectAtIndex:1];
                }else{
                    _launcher = [self.navigationController.viewControllers objectAtIndex:0];
                }
                _launcher.selectedIndex = 0;

// 这里如果程序是通过后台进来的，那么获取到得这个currentVC里是没有子VC的需要手动创建放进去否则在详情页中navigationController的返回按钮会使程序挂掉

                if ([self.isbackGround isEqualToString:@"yes"]) {
                    XNavigationController *currentVC = (XNavigationController *) _launcher.selectedViewController;
                    MsgPushTableViewController *pushTableVC = [[MsgPushTableViewController alloc] init];
                    NSLog(@"%@",pushTableVC);
                    currentVC.viewControllers = @[pushTableVC];
                    [pushTableVC.navigationController pushViewController:msgDetailView animated:YES];

                }else{
                    XNavigationController *currentVC = (XNavigationController *) _launcher.selectedViewController;

                    [currentVC pushViewController:msgDetailView animated:YES];
                }
            }

        }];
    }
}

OK，至此推送的基本事项完成，写的仓促没有准备效果图，有什么疑问直接留言就好会及时回复的欢迎交流进步
