在我的项目中，我必须得到GCM推送通知，我完成了一切，并且服务器发送给我注册令牌和GCM服务器连接完美，但通知没有进入我的设备。

但是通知没有收到我的设备，我是否需要在这里做额外的事情？我忘了添加任何东西吗？我上传了.p12证书，我已经完全创建了APNs证书，为什么我没有得到GCM通知，而且“didReceiveRemoteNotification”方法没有调用我是否必须附上服务器API密钥或SenderId以及上面写的代码。
答案 0 :(得分：30)
如果你看到你的控制台第一行：
2015-07-17 11:20:41.701 GCMSwift[1134:421304] You've implemented -[<UIApplicationDelegate> application:didReceiveRemoteNotification:fetchCompletionHandler:], but you still need to add "remote-notification" to the list of your supported UIBackgroundModes in your Info.plist
您需要启用必需的背景模式。请按照以下步骤操作：
这将在Info.plist中添加后台模式支持。
