1.提示“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.”
解决：在项目配置的Capabilities菜单的Background Modes菜单中选中“Remote notification”。如果没有看到选项菜单，需要将Background Modes菜单打到ON状态。
2.提示“Not get deviceToken yet. Maybe: your certificate not configured APNs? or current network is not so good so APNs registration failed? or there is no APNs register code? Please refer to JPush docs.”
原因：我的CodeSigning中的Provision Profile没有选择正确，原因是我在apple的dev中心修改了配置，但没有更新到xcode。更新可以在账户管理中找到，xcode菜单在Xcode->Preferences->account选项卡，在Apple IDs中找到你得账号，点击右下角的view detail按钮，在弹出的窗口中点击左下角的刷新按钮即可刷新最新的Provision Profile。最后在CodeSigning中的Provision Profile中选择最新的值即可。
