问题描述
我正在尝试使用 Firebase
进行推送通知。我已成功安装 Firebase
和 Firebase消息
通过 Cocoapods
。
I am trying to use Firebase
for push notification. i have successfully installed the Firebase
And Firebase messaging
via Cocoapods
.
我使用以下代码
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[FIRApp configure];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(tokenRefreshCallback:) name:kFIRInstanceIDTokenRefreshNotification object:nil];
UIUserNotificationType allNotificationsType = (UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge);
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:allNotificationsType categories:nil];
[application registerUserNotificationSettings:settings];
[application isRegisteredForRemoteNotifications];
return YES;
}
-(void)applicationDidEnterBackground:(UIApplication *)application {
[[FIRMessaging messaging] disconnect];
NSLog(@"Disconnect from FCM");
}
- (void)applicationDidBecomeActive:(UIApplication *)application {
[self connectToFirebase];
}
- (void) application:(UIApplication *) application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:( void (^)(UIBackgroundFetchResult))completionHandler{
// Pring The Message Id
NSLog(@"Mesage Id : %@",userInfo[@"gcm.message_id"]);
// Print Full Message
NSLog(@"%@",userInfo);
}
#pragma mark -- Custom Firebase code
- (void)tokenRefreshCallback:(NSNotification *) notification{
NSString *refreshedToken = [[FIRInstanceID instanceID] token];
NSLog(@"IstanceID token: %@", refreshedToken);
// Connect To FCM since connection may have failed when attempt before having a token
[self connectToFirebase];
}
-(void) connectToFirebase{
[[FIRMessaging messaging] connectWithCompletion:^(NSError * _Nullable error)
{
if ( error != nil)
{
NSLog(@"Unable to Connect To FCM. %@",error);
}
else
{
NSLog((@"Connected To FCM"));
}
}];
}
当我使用连接 Xcode 当我从Firebase控制台发送消息时,我面临以下问题
When i run the above code using my iPhone connected with Xcode
i am facing the following issues when i send a message from Firebase Console
1)。当应用程序处于前台(活动)时,Log显示以下消息
1). when the app is in foreground (active), Log shows the below message
Mesage Id : (null){
CustommData = "First Message";
"collapse_key" = "abcd.iospush.FireBasePush";
from = 555551391562;
notification = {
badge = 4;
body = "Test Message";
e = 1;
sound = default;
sound2 = default;
};
}
通知消息ID
是 null
。
2)。我的手机未在通知中心中显示任何通知,无论应用是在前台,背景还是已关闭
2). My phone doesn't show any notification in Notification Centre whether App is in Foreground , Background or Closed
我希望用户在收到推送通知时应用程序位于后台,前台或已关闭
I want user to receive push notifications when App is in Background , Foreground or Closed
推荐答案
您必须调用 [[UIApplication sharedApplication] registerForRemoteNotifications];
正确注册远程通知。
You must call [[UIApplication sharedApplication] registerForRemoteNotifications];
to properly register for remote notifications.
配置远程通知以供后台使用
您是否配置了应用的后台模式以接受远程通知?
您可以点击:项目名称 - > 功能 - > 后台模式
Have you configured your app's background modes to accept remote notifications?You can do this by clicking: Project Name -> Capabilities -> Background Modes
启用此功能,然后勾选远程通知旁边的框,如下面的屏幕截图所示。
Turn this on and then tick the box beside Remote Notifications as seen in the screenshot below.
