接著上一篇繼續，當接到通知需要的操作

一、APP在前臺

       實現效果，在前臺無論在那個頁面都在頂部展示一個橫條，顯示推送資訊，點選時跳到自己處理的頁面(10秒不點選自動移除這個橫條view)

       直接上程式碼吧，講解一下思路，有問題留言

       當接到通知，建立一個view放在window上並攜帶通知的資訊，在加一個同樣大小的control新增點選事件，點選執行我們需要操作的事項和跳轉相應頁面，方法如下

       //應用在前臺 或者後臺開啟。
    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:@"返回條.jpg"];
        _notifyView.userInteractionEnabled = YES;
        UIImageView *goImView = [[UIImageView alloc] initWithFrame:CGRectMake(KscreenWidth-26, 13, 11, 18)];
        goImView.image = [UIImage imageNamed:@"箭頭"];
        [_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在後臺

       上面直接else一下 呼叫 [self skipViewC]上面control點選事件即可。看實現方法

       這裡if裡的是，直接返回了需要的資料 或者不需要返回資料只需要跳轉頁面的實現方式，將APP啟動方法裡的啟動頁宣告為全域性，在這裡直接使用跳轉到相應頁面

       else裡的是，由於展示詳情頁需要展示好多內容所以返回一個id 在通過id 查詢資訊展示跳轉

       - (void)skipViewC{
   
    _launcher.selectedIndex = 0;
    
    [self removeALarmView];
    
    NSString *msgId = _userInfoDic[@"formid"];
    
    if ([msgId isEqualToString:@"todo"]) {
        
        TaskListViewController *taskListView = [[TaskListViewController alloc] init];
        taskListView.title = @"待辦事項";
        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{
    
    
        //請求獲取到msgAcceptPush 物件 在跳轉
        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 = @"通知詳情";
                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;

                // 這裡如果程式是通過後臺進來的，那麼獲取到得這個currentVC裡是沒有子VC的需要手動建立放進去否則在詳情頁中navigationController的返回按鈕會使程式掛掉

                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，至此推送的基本事項完成，寫的倉促沒有準備效果圖，有什麼疑問直接留言就好會及時回覆的 歡迎交流進步
