ios - 应用程序设置 FirebaseMessaging 委托(delegate)时应用程序崩溃

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 中崩溃，我在其中尝试设置 Firebase 消息传递的委托(delegate)。

这是代码

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

在第二行中，它崩溃并显示崩溃消息，如下所示:

Answer 1

如果您不使用 pod，则必须为您的目标添加 objC 链接器标志。

来自文档:

“无需 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。这是一个约 1GB 的文件，下载可能需要一些时间。

解压缩文件，然后查看您要包含在应用中的框架的自述文件。

在目标的build设置中的“其他链接器设置”中添加 ObjC 链接器标志。”
