我什么也得不到。我的应用无论是在前台还是在后台都不会收到推送消息。
请多多帮助我。
你在图中添加的token就是设备token值。令牌值在日志中可见。
编辑
我看到了答案并跟着它，但它不起作用。

【参考方案1】：你能把 GoogleService-Info.plist 文件放到你的项目中吗？
在我的代码中尝试这个 100% 工作

【讨论】：
请看我编辑的问题。该文件已添加。 我应该将它添加到函数的顶部吗？【参考方案2】：我看到了答案并按照它，但它不起作用。但是，当你在Fire Base上添加了一个新项目，再次添加了iOS应用，试了试，就成功了。我不确定出了什么问题。那是我的代码有问题吗？我想，但是当我在问题中使用代码时，它也起作用了。我只是为我的解决方案创建并添加了一个新项目。
