Java 当应用程序处于后台时，当我单击通知项（在通知栏中）时，应用程序调用了哪个方法？

java ios notifications

Java 当应用程序处于后台时，当我单击通知项（在通知栏中）时，应用程序调用了哪个方法？,java,ios,notifications,Java,Ios,Notifications,我在互联网上搜索发现：在iOS7之后，即使某个应用程序被杀死，如果用户单击与该应用程序关联的通知，该应用程序也会调用此方法： - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler

我在互联网上搜索发现：在iOS7之后，即使某个应用程序被杀死，如果用户单击与该应用程序关联的通知，该应用程序也会调用此方法：

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler
我使用的是一个临时配置文件，应用程序在后台，并没有被杀死

我的代码如下：

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler {

// JPush
// IOS 7 Support Required
[JPUSHService handleRemoteNotification:userInfo];  // handle the notification 
completionHandler(UIBackgroundFetchResultNewData);

NSLog(@"%@--userinfo", userInfo);
NSLog(@"%ld--applicationState", (long)[UIApplication sharedApplication].applicationState);

public static void pushIos(List<String> registrationIds,Map<String,String> map){
    PushPayload payload = PushPayload.newBuilder()
            .setPlatform(Platform.ios())
            .setAudience(Audience.registrationId(registrationIds))
            .setNotification(Notification.newBuilder()
                    .addPlatformNotification(IosNotification.newBuilder()
                            .setAlert(map.get("title"))
                            .incrBadge(1)
                            .setSound("happy.caf")
                            .addExtra("pushId", map.get("pushId"))
                            .addExtra("pushType",map.get("pushType"))
                            .addExtra("title", map.get("title"))
                            .build())
                    .build())
            .setMessage(Message.content("123"))
            .setOptions(Options.newBuilder()
                     .setApnsProduction(true)
                    .build())
            .build();
    try {
        PushResult result = jPushClient.sendPush(payload);
        System.out.println(result);
    }catch(APIConnectionException e){
        e.printStackTrace();
    } catch (APIRequestException e) {
        e.printStackTrace();
    }
}
当我测试时，我在设备日志中什么也没有得到

在
应用程序中注册APN的我的代码：didFinishLaunchingWithOptions
： 我的iphone操作系统版本是
10.2

// 7.push  regist
if (IOS10) {
    UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
    center.delegate = self;
    [center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert) completionHandler:^(BOOL granted, NSError * _Nullable error) {
        if (!error) {
            NSLog(@"succeeded!");
        }else {
            NSLog(@"error:%@", error);
        }
    }];
} else if (IOS8_10){//iOS8-iOS10

参考Chandan的评论，如果将
content available=1
添加到
aps
字典中，我们可以唤醒应用程序，但是如何将值添加到
aps
使用
java
：

代码如下：

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler {

// JPush
// IOS 7 Support Required
[JPUSHService handleRemoteNotification:userInfo];  // handle the notification 
completionHandler(UIBackgroundFetchResultNewData);

NSLog(@"%@--userinfo", userInfo);
NSLog(@"%ld--applicationState", (long)[UIApplication sharedApplication].applicationState);

public static void pushIos(List<String> registrationIds,Map<String,String> map){
    PushPayload payload = PushPayload.newBuilder()
            .setPlatform(Platform.ios())
            .setAudience(Audience.registrationId(registrationIds))
            .setNotification(Notification.newBuilder()
                    .addPlatformNotification(IosNotification.newBuilder()
                            .setAlert(map.get("title"))
                            .incrBadge(1)

看起来您正在尝试接收远程推送通知。您是否记得注册远程推送通知？此外，还需要启用推送通知功能

基本上，有三个步骤

  • 为应用程序启用推送通知功能
  • 在应用程序的启动时间代码中向APNs注册
  • 实现对处理传入远程通知的支持
    • 您显示的代码仅用于步骤3

    请参见

    试试这些代码行，我想它们会解决您的问题

    这是注册远程通知并处理它们的代码 UnuseNotificationCenterDelegate添加此委托

    Application:didReceiveMemotentification:
    仅当您将值为

当应用程序位于前台时，您可以检查可用的内容
    

    NSString* contentAvailable = [NSString stringWithFormat:@"%@", [[userInfo valueForKey:@"aps"] valueForKey:@"content-available"]];

    

    仅供参考：-
    这是Xcode8+iOS10的一个bug，NSLog根本不显示。你可以查看这个链接@Chandan，抱歉，兄弟，这不是由你说的错误引起的，我也可以找到其他NSLog信息。如果我没有错，我们在使用临时配置文件时无法调试。那么它将如何显示NSLog。@Chandan，请看我的这篇文章：application:DidReceiveMemotentification:只有当您将值为1的内容可用键添加到通知负载中时，才会在后台调用。当然，我是这样做的，这样我可以接收远程通知，然后我可以单击推送通知栏的项，是吗？你能显示步骤2的代码吗？如果出现错误，可能会导致您的应用程序未正确接收推送通知。谢谢您的回答，我的意思是单击通知项重新进入我的应用程序，我的应用程序未通过
    -（void）application:（UIApplication*）application didReceiveMemotentification:（NSDictionary*）userInfo fetchCompletionHandler:（void（^）（UIBackgroundFetchResult）completionHandler方法，我还测试了您的anser。我的应用程序没有调用我发布的此方法。请尝试实现上述代码，我相信您不会遇到任何问题。我已经测试了此代码
