一、配置APNs

蘋果APNs(英文全稱：Apple Push Notification Service)

1.配置開發證書

2.配置生產證書

和配置開發證書的流程相同。

3.將配置好的證書導出為 .p12 文件

一、注冊極光推送帳號

可登錄 極光推送官網 注冊帳號。

注冊成功後進入控制台

二、集成極光推送SDK

sdk地址

我使用的是JPush-iOS-SDK-2.1.0。下載的文件裡有個pdf文件iOS+SDK+Integration+Guide.pdf，介紹了集成極光推送的詳細代碼。

在工程文件中，做如下設置：

下面是我寫的代碼：

AppDelegate.m文件

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    //設置appKey
    [JPushConfig registerJPush:launchOptions];
    return YES;
}


#pragma mark 修改通知處理函數
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(nonnull void (^)(UIBackgroundFetchResult))completionHandler {
    //推送消息攜帶 content-available: 1 是Background 運行的必須參數，如果不攜帶此字段則與iOS7 之前版本的普通推送一樣。
    //清空角標
    [JPUSHService resetBadge];
    if (!userInfo) {
        completionHandler(UIBackgroundFetchResultNoData);
        return ;
    }
    completionHandler(UIBackgroundFetchResultNewData);
    //根據服務器設置的 userInfo 的格式，進行解析
}

// Required
-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    [JPUSHService registerDeviceToken:deviceToken];
}

// Required
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
    [JPUSHService handleRemoteNotification:userInfo];
    application.applicationIconBadgeNumber = 0;
}

- (void)application:(UIApplication *)application
didReceiveLocalNotification:(UILocalNotification *)notification {
    [JPUSHService showLocalNotificationAtFront:notification identifierKey:nil];
}

-(void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
}

- (void)applicationDidBecomeActive:(UIApplication *)application {
    [application setApplicationIconBadgeNumber:0];
}

JPushConfig.m文件

/** 注冊 JPush */
+(void)registerJPush:(NSDictionary *)launchOptions {
    // Required
    if ([[UIDevice currentDevice].systemVersion floatValue] >= 8.0) {
        //可以添加自定義categories
        [JPUSHService registerForRemoteNotificationTypes:(UIUserNotificationTypeBadge |
                                                          UIUserNotificationTypeSound |
                                                          UIUserNotificationTypeAlert)
                                              categories:nil];
    } else {
        //categories 必須為nil
        [JPUSHService registerForRemoteNotificationTypes:(UIUserNotificationTypeBadge |
                                                          UIUserNotificationTypeBadge |
                                                          UIUserNotificationTypeBadge)
                                              categories:nil];
    }
    NSString *appKey = @"極光推送生成的KEY";
    NSString *channel = @"App Store";//發布渠道,可以隨便定義
    BOOL isProduction = false;//這個要根據極光推送控制台裡設置的是開發環境還是生產環境
    //Required
    [JPUSHService setupWithOption:launchOptions
                           appKey:appKey
                          channel:channel
                 apsForProduction:isProduction];
}

收到通知消息後，在AppDelegate.m跳轉到指定界面的方法：

    UIViewController *vc = [[UIViewController alloc] init];
    [self.window.rootViewController presentViewController:vc animated:YES completion:nil];
