IP Address ranges for APNS servers? [closed]

阅读更多关于 IP Address ranges for APNS servers? [closed]

问题 Does anyone have a complete list of all IP addresses used by the Apple Push Notification Service? I know that Apple uses a content delivery network to spread out these requests, and DNS lookups will return servers close to the requestor's location - the problem I have is in locating all of these servers that handle content for the United States. For example: $ nslookup gateway.push.apple.com Non-authoritative answer: canonical name = gateway.push-apple.com.akadns.net. Address: 17.172.238.216

问题 In official documentation you can find the info: Each push notification includes a payload.

Alternative to UserNotificationCenterDelegate's willPresent when app is in background

阅读更多关于 Alternative to UserNotificationCenterDelegate's willPresent when app is in background

问题 I am trying to figure out whether I can accomplish my goal through Local Notifications, or whether I need to switch to Remote Notifications. I'm practicing iOS 10 / Swift 3 by building an alarm program that plays the latest episode of a RSS-updated radio show at a set time of day. When the app is in the foreground, this is easy to execute through UNUserNotificationCenterDelegate's willPresent function. I just use willPresent to fetch the latest episode, and play it through an AVAudio Player.

I am attempting to run the Ray Wenderlich tutorial found at Apple Push Notification Services in iOS 6 Tutorial: Part 1/2 . I created an AppID and SSL certificate and keys and PEM files in a local directory. Afterwards, I got to the step to test whether the certificate works, and I invoked the following command from this local directory: $ openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert PushChatCert.pem -key PushChatKey.pem This produced a lot of output. In the middle of the output was the following: verify error:num=20:unable to get local issuer certificate verify return:0

阅读更多关于 application:didReceiveRemoteNotification:fetchCompletionHandler Not Called

问题 It appears the function application:didReceiveRemoteNotification:fetchCompletionHandler is not called when the app has been forcefully quit. It was my impression that the function would be invoked no matter what state the app was in, but it appears that it is only called if the app is already running in the background. Is there a way to wake up an app in the background if it is not already running using the new iOS 7 remote notification background mode? 回答1: application
