我一直试图在我的ios应用程序中获取firebase推送通知很长一段时间。我已经尝试了我能找到的互联网上的一切。但遗憾的是没有运气。 任何帮助将不胜感激。
我正在通过firebase控制台发送通知。
这是我的代码：
#import "AppDelegate.h"
#if defined(__IPHONE_10_0) && __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_10_0
@import UserNotifications;
#endif
@import Firebase;
@import FirebaseInstanceID;
@import FirebaseMessaging;
#if defined(__IPHONE_10_0) && __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_10_0
@interface AppDelegate () <UNUserNotificationCenterDelegate, FIRMessagingDelegate>
@end
#endif
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
// [START configure_firebase]
[FIRApp configure];
// [END configure_firebase]
if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_9_x_Max) {
UIUserNotificationType allNotificationTypes =
(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge);
UIUserNotificationSettings *settings =
[UIUserNotificationSettings settingsForTypes:allNotificationTypes categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
} else {
// iOS 10 or later
#if defined(__IPHONE_10_0) && __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_10_0
UNAuthorizationOptions authOptions =
UNAuthorizationOptionAlert
| UNAuthorizationOptionSound
| UNAuthorizationOptionBadge;
[[UNUserNotificationCenter currentNotificationCenter]
requestAuthorizationWithOptions:authOptions
completionHandler:^(BOOL granted, NSError * _Nullable error) {
}
];
// For iOS 10 display notification (sent via APNS)
[[UNUserNotificationCenter currentNotificationCenter] setDelegate:self];
// For iOS 10 data message (sent via FCM)
[[FIRMessaging messaging] setRemoteMessageDelegate:self];
#endif
}
[[UIApplication sharedApplication] registerForRemoteNotifications];
// Add observer for InstanceID token refresh callback.
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(tokenRefreshNotification:)
name:kFIRInstanceIDTokenRefreshNotification object:nil];
return YES;
}
// [START refresh_token]
- (void)tokenRefreshNotification:(NSNotification *)notification {
// Note that this callback will be fired everytime a new token is generated, including the first
// time. So if you need to retrieve the token as soon as it is available this is where that
// should be done.
NSString *refreshedToken = [[FIRInstanceID instanceID] token];
NSLog(@"InstanceID token: %@", refreshedToken);
NSLog(@"id = ---------- %@",[[[UIDevice currentDevice] identifierForVendor] UUIDString]);
[[NSNotificationCenter defaultCenter] postNotificationName:@"fcmtoken" object:refreshedToken];
// Connect to FCM since connection may have failed when attempted before having a token.
[self connectToFcm];
// TODO: If necessary send token to application server.
}
// [END refresh_token]
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
// If you are receiving a notification message while your app is in the background,
// this callback will not be fired till the user taps on the notification launching the application.
// TODO: Handle data of notification
// Print message ID.
NSLog(@"Message ID: %@", userInfo[@"gcm.message_id"]);
// Print full message.
NSLog(@"didReceiveRemoteNotification= %@", userInfo);
}
// [START ios_10_message_handling]
// Receive displayed notifications for iOS 10 devices.
#if defined(__IPHONE_10_0) && __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_10_0
- (void)userNotificationCenter:(UNUserNotificationCenter *)center

}
- (void)applicationWillResignActive:(UIApplication *)application {
// Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
// Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game.
}
- (void)applicationDidEnterBackground:(UIApplication *)application {
// Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
// If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
//[[FIRMessaging messaging] disconnect];
// NSLog(@"Disconnected from FCM");
}
- (void)applicationWillEnterForeground:(UIApplication *)application {
// Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
}

// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.

在日志中，我能够看到为我的设备生成的令牌，当我向令牌应用发送通知时，它也不会在后台接收通知。
但是当我启动我的应用程序时，它会调用applicationReceivedRemoteMessage:，我可以看到已发出警告。
可能有什么问题请提前帮助和谢谢！

我的项目发生这种情况的原因是因为我使用与我的开发数据库生成的相同设备令牌 ...结果我需要删除并重新安装我的应用程序电话并注册获取新设备令牌的通知并生成新的FCM注册ID ..有效且我已成功收到我的通知。
希望这有帮助。

当您的APP进入后台时，Apple APNS服务会发送通知消息，因此我认为您的 .cer 是错误的; Apple有两个.cer来推送编码/ AppStore中的通知，如果您的APP没有进入AppStore，请尝试使用开发人员.cer进行此操作。
我的英语不好但可能对你有帮助！
====编辑==== 试试这个？
NSString *pushToken = [[[[deviceToken description]
stringByReplacingOccurrencesOfString:@"<" withString:@""]
stringByReplacingOccurrencesOfString:@">" withString:@""]
stringByReplacingOccurrencesOfString:@" " withString:@""];

我通过在XCODE 8.1中启用推送通知功能来解决此问题
点击：
.xcodeproj - ＆gt;能力 - ＆gt;启用推送通知
我已经重新创建了配置文件。
