Question

我的应用尝试使用Firebase远程通知，我遵循了Firebase指南。现在，我的应用程序在AppDelegate崩溃，我试图在其中设置Firebase消息传递的委托。

这是代码

[FIRApp configure];
[FIRMessaging messaging].delegate = self;

在第二行中，它崩溃并显示以下崩溃消息：

Answer 1

调用委托时，必须确保已编写该委托的所有必需方法。

检查在您的Appdelegate中调用了以下方法。

index household carID   waypoint            absent
497   201248    2       from home       15   
498   201248    2                       18
499   201248    2       to home         19   4
500   201248    1       from home       10
501   201248    1       to home         10
502   201248    1                       19
503   201248    1       to home         0    14
504   201248    2       from home       8
505   201248    2                       9
506   201248    2       to home         9    11 (because the final end time is 19:00 see upper table)

或确保在您的Appdelegate中编写 FIRMessagingDelegate

-(void)messaging:(FIRMessaging *)messaging didReceiveRegistrationToken:(NSString *)fcmToken 
{
}

Answer 2

您需要更改Firebase配置方法。

命名为

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 42.0), dispatch_get_main_queue(), ^{
       [FIRApp configure];
 });

它将解决您的问题。

Answer 3

import FirebaseMessaging
FirebaseApp.configure()
Messaging.messaging().delegate = self

// MARK：-消息代理方法..............................

func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
            let token = Messaging.messaging().fcmToken
            print("FCM token: \(token ?? "")")
}

Answer 4

如果您不使用Pod，则必须为目标添加objC链接器标志。

从文档中：

”不使用CocoaPods进行集成如果您不想使用Cocoapods，您仍然可以通过直接导入框架来利用Firebase SDK。

下载框架SDK zip。这是一个大约1GB的文件，可能需要一些时间才能下载。

解压缩文件，然后查看要包含在应用程序中的框架的自述文件。

在目标的构建设置的“其他链接器设置”中添加ObjC链接器标志。”
