一、問題描述

在應(yīng)用中經(jīng)常會添加推送，在我們的項(xiàng)目中也用到了推送，推送添加的是友盟的第三方推送方案，接入友盟的SDK只要按照步驟，接進(jìn)來也十分簡單，完全可以收到推送數(shù)據(jù)，但問題是在收到推送數(shù)據(jù)時如何去處理收到的信息以及如何跳轉(zhuǎn)相應(yīng)的界面？這是我這篇文章主要介紹的。

二、解決思路

iOS提供收到推送時的處理方法，但是收到推送應(yīng)該從幾個方面來考慮這才是關(guān)鍵的點(diǎn)，對于一個剛接觸的人來說也是不知所措，之后再網(wǎng)上查找零零碎碎的找到了一些突破點(diǎn)，才完成了對于收到推送的處理方式，主要從以下兩個方面來考慮。

1>當(dāng)程序沒有死掉即在在前臺或者后臺時

/**
 *  收到推送時會在AppDelegate的didReceiveRemoteNotification中響應(yīng)事件
 */
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
       // 這里做收到推送時的處理userInfo為收到的數(shù)據(jù)
}

1)程序在運(yùn)行在前臺即處于UIApplicationStateActive狀態(tài)

在UIApplicationStateActive時只需要定義一個alertView來處理，在代理方法里跳轉(zhuǎn)相應(yīng)的詳情，當(dāng)然這個跳轉(zhuǎn)必須要有navigationController來跳轉(zhuǎn)并且navigationController要作為一個屬性。

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
    // 保存推送數(shù)據(jù)
     self.userInfos = userInfo;
      // 定制自定義的彈框
        if([UIApplication sharedApplication].applicationState == UIApplicationStateActive)
        {
            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"有新的要聞推薦哦~"
            message:userInfo[@"aps"][@"alert"]
            delegate:self
            cancelButtonTitle:@"取消"
            otherButtonTitles:@"立即前往", nil];
            [alertView show];
        }
}

alerView的代理方法里執(zhí)行跳轉(zhuǎn)詳情

#pragma mark -跳轉(zhuǎn)到推送詳情頁
- (void)notificationDetailVc {
    INHelpProtrolViewController *help = [[INHelpProtrolViewController alloc]init];
    help.urlString = self.userInfos[@"src_link"];
    [self.mainNavigationController pushViewController:help animated:YES];
}

2)程序在運(yùn)行在后臺但沒死掉即處于UIApplicationStateInactive狀態(tài)時

當(dāng)你點(diǎn)擊通知欄上的通知時程序程序會觸發(fā)didReceiveRemoteNotification方法

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

     if ([UIApplication sharedApplication].applicationState == UIApplicationStateInactive){
            // 跳轉(zhuǎn)詳情頁面
                INHelpProtrolViewController *help = [[INHelpProtrolViewController alloc]init];
    help.urlString = self.userInfos[@"src_link"];
    [self.mainNavigationController pushViewController:help animated:YES];
        }
}

2>當(dāng)程序完全死掉時

當(dāng)程序完全死掉時.jpg

// 程序啟動時
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
/// 上面創(chuàng)建window，navgationController等操作，創(chuàng)建完成后判斷是否是由推送打開之后跳轉(zhuǎn)
#pragma mark -判斷是否由推送打開
    // 判斷是否是通過推送打開app
    NSDictionary *userInfos = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
    if (userInfos) {
        // 保存數(shù)據(jù)
        self.userInfos = userInfos;
        // 跳轉(zhuǎn)詳情
           INHelpProtrolViewController *help = [[INHelpProtrolViewController alloc]init];
    help.urlString = self.userInfos[@"src_link"];
    [self.mainNavigationController pushViewController:help animated:YES];
    }
    return YES;
}
