在使用iOS推送時，出現下面錯誤：

**[1412:60b] You've implemented -[<UIApplicationDelegate> application:performFetchWithCompletionHandler:], but you still need to  
add "fetch" to the list of your supported UIBackgroundModes in your Info.plist. 
  
 
**[1412:60b] 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. 

 解決方法：PORJECT --> Capabilities --> Background Modes --> Background fetch & Remote notifications -->選中為on 狀態

我還遇到一種情況   

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. 

破解方法還 和上面是一樣的，如圖
