iOS开发-集成个推远程推送

证书配置+个推应用配置略过

Xcode集成

在项目中添加 Notification Service Extension

Notification Service Extension

填写Target信息时需要注意以下两点:

Extension 的 Bundle Identifier 不能和 Main Target(也就是你自己的 App Target)的 Bundle Identifier 相同,否则会报 BundeID 重复的错误。

Extension 的 Bundle Identifier 需要在 Main Target 的命名空间下,比如说 Main Target 的 BundleID 为 ent.getui.xxx,那么Extension的BundleID应该类似与ent.getui.xxx.yyy这样的格式。如果不这么做,会引起命名错误。

因此我们建议使用<Main Target Bundle ID>.NotificationService 格式作为Extension的BundleID.

CocoaPods集成

  #个推
  pod 'GTSDK', '2.0.0.0-noidfa'
  
  target 'NotificationService' do
      platform :ios, "10.0"
      pod 'GTExtensionSDK'
  end

开启推送功能

Xcode 8.x 以上,必须开启Push Notification能力。找到应用Target设置中的Capabilities -> Push Notifications,确认开关已经设为ON状态。如果没有开启该开关,在 Xcode 8.x 上编译后的应用将获取不到DeviceToken

后台运行权限设置

为了更好支持消息推送,提供更多的推送样式,提高消息到达率,需要配置后台运行权限:

在项目设置中添加以下系统库支持:

libc++.tbd
libz.tbd
libsqlite3.tbd
Security.framework
MobileCoreServices.framework
SystemConfiguration.framework
CoreTelephony.framework
AVFoundation.framework
CoreLocation.framework
UserNotifications.framework (iOS 10 及以上需添加,使用 Optional 方式接入)
AdSupport.framework   (如果使用无IDFA版本SDK,则需删除该 AdSupport 库)

添加 GtExtensionSdk 依赖库

libz.tbd
libsqlite3.tbd
GTExtensionSDK.framework
UserNotifications.framework

NotificationService.m

#import <GTExtensionSDK/GeTuiExtSdk.h>


- (void)didReceiveNotificationRequest:(UNNotificationRequest *)request withContentHandler:(void (^)(UNNotificationContent * _Nonnull))contentHandler {
    self.contentHandler = contentHandler;
    self.bestAttemptContent = [request.content mutableCopy];
    
    [GeTuiExtSdk handelNotificationServiceRequest:request
                          withAttachmentsComplete:^(NSArray *attachments, NSArray *errors) {
                              //TODO:用户可以在这里处理通知样式的修改,eg:修改标题
                              //self.bestAttemptContent.title = [NSString stringWithFormat:@"%@ [Success]", self.bestAttemptContent.title];

    // Called just before the extension will be terminated by the system.
    // Use this as an opportunity to deliver your "best attempt" at modified content, otherwise the original push payload will be used.

iOS 10 以前,为处理 APNs 通知点击事件,统计有效用户点击数,需在AppDelegate.m里的didReceiveRemoteNotification回调方法中调用个推SDK统计接口:

/** APP已经接收到“远程”通知(推送) - 透传推送消息 {app 在后台没杀死或者杀死 点击通知 首先进入的方法} */
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler {
    // 处理APNs代码,通过userInfo可以取到推送的信息(包括内容,角标,自定义参数等)。如果需要弹窗等其他操作,则需要自行编码。
    DLog(@"\n>>>[Receive RemoteNotification - Background Fetch]:%@\n\n",userInfo);
    
    self.isLaunchedByNotification = YES;
    //静默推送收到消息后也需要将APNs信息传给个推统计
    [GeTuiSdk handleRemoteNotification:userInfo];
    completionHandler(UIBackgroundFetchResultNewData);
    
    
}
#if __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_10_0
//  iOS 10: App在前台获取到通知
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler  API_AVAILABLE(ios(10.0)){
    
    DLog(@"willPresentNotification:%@", notification.request.content.userInfo);
    
    // 根据APP需要,判断是否要提示用户Badge、Sound、Alert
    completionHandler(UNNotificationPresentationOptionBadge | UNNotificationPresentationOptionSound | UNNotificationPresentationOptionAlert);
}

//  iOS 10: 点击通知进入App时触发,在该方法内统计有效用户点击数
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)(void))completionHandler  API_AVAILABLE(ios(10.0)){
    DLog(@"didReceiveNotification:%@", response.notification.request.content.userInfo);
    
    self.isLaunchedByNotification = YES;
    // [ GTSdk ]:将收到的APNs信息传给个推统计
    [GeTuiSdk handleRemoteNotification:response.notification.request.content.userInfo];
    completionHandler();
}

#endif
/** SDK启动成功返回cid */
- (void)GeTuiSdkDidRegisterClient:(NSString *)clientId {
    //个推SDK已注册,返回clientId
    
    DLog(@"-=-=-=----\n>>>[GeTuiSdk RegisterClient]:%@\n\n", clientId);
    
    // 通过接口上传的APP服务器
}

SDK 在线时(即 App 在前台运行时)进行消息推送,该消息将直接通过个推通道发送给 App ,通常这种方式比通过APNs发送来得更及时更稳定;当 SDK 离线时(即停止 SDKApp 后台运行 或 App 停止状态时)进行消息推送,个推平台会给苹果 APNs 推送消息,同时保存个推通道的离线消息,当 SDK 重新上线后,个推平台会重新推送所有离线的消息

APP 可以通过[GeTuiSdkDelegate GeTuiSdkDidReceivePayloadData]回调方法获取透传消息,其中payloadData参数为透传消息数据,offLine参数则表明该条消息是否为离线消息。示例代码如下:

/** SDK收到透传消息回调 {app在前台 只走这一个方法}{app在后台,进来前台第二个走的方法} */
- (void)GeTuiSdkDidReceivePayloadData:(NSData *)payloadData andTaskId:(NSString *)taskId andMsgId:(NSString *)msgId andOffLine:(BOOL)offLine fromGtAppId:(NSString *)appId {
    
    [UIApplication sharedApplication].applicationIconBadgeNumber = 0;
    //收到个推消息
    NSString *payloadMsg = nil;
    if (payloadData) {
        payloadMsg = [[NSString alloc] initWithBytes:payloadData.bytes length:payloadData.length encoding:NSUTF8StringEncoding];
    }
    
    NSDictionary *payLoadMegDic = [NSJSONSerialization JSONObjectWithData:payloadData options:NSJSONReadingMutableLeaves error:nil];
    DLog(@"%@",payLoadMegDic);
    if (offLine) {
            if (payLoadMegDic) {
            if (self.isLaunchedByNotification) { // app是通过点击通知栏进入前台
            UITabBarController *_tab = (UITabBarController *)(self.window.rootViewController);
            UINavigationController *nva = (UINavigationController *)_tab.viewControllers[_tab.selectedIndex];
            // 根据payLoadMegDic判断跳转类型
                self.isLaunchedByNotification = NO;
            }else{
                // app是通过点击icon进入前台,在这里不做操作
            }
        }

        NSString *msg = [NSString stringWithFormat:@"taskId=%@,messageId:%@,payloadMsg:%@%@",taskId,msgId, payloadMsg,offLine ? @"<离线消息>" : @""];
        DLog(@"\n>>>[GexinSdk ReceivePayload]:%@\n\n", msg);
        
    }else if(!self.isLaunchedByNotification){
        // app已经处于前台,提示框提示
        // 在这里拿不到apns 里的title body! 如果想要处理的话可以让服务端把aps 的内容传到transmissionContent 透传内容里 ,应用在线的时候可以拿到这个透传
        self.isLaunchedByNotification = NO;
        // 转换成一个本地通知,显示到通知栏,你也可以直接显示出一个alertView,只是那样稍显aggressive
    }
    
    
    
}
