First App installation-Problems with authorized network access, first app Installation
App installation for the first time-pitfalls for authorizing network access 1. What is this pop-up box?

.. Picture

2. How to trigger

1. First, you have to have an iPhone of the China line version.
2. The system version is later than iOS10.
3. When an App is installed for the first time, network switching is triggered as long as the App performs network requests.

3. Does it play every time? How can I reinstall the App after uninstalling it?

This dialog box is triggered only when the App is installed for the first time and a network request is triggered. in addition, the user will be given a clear network permission status (wifi/wifi + 4g3g2g/notNetwork) for the App, otherwise the pop-up box will not disappear.

Problems encountered in the project and solutions 1. the project encountered a special problem. AFN was not used first, but it does not matter. data Loading and startup of the Project App must be performed before login. at first, these network switches were placed in In didfinishlaunchingwitexceptions.
This will lead to a pitfall. At this time, the Window does not have rootcontroller, so even if the system pop-up box is triggered, sometimes the pop-up box may appear after the App is closed. the second pitfall: because Apple does not have an API for requesting network permissions. therefore, we cannot obtain the user's clicking result. Are users allowed or not allowed. generally, the user's authorization can only be determined by constantly checking the network. 2. solution (how to avoid embarrassment elegantly)

Knock on the blackboard
First, before real data loading/network switching. use the timer to continuously initiate network detection. data interaction is performed only when the user is authorized and the network connection is detected again.
If the network is not connected (There are pitfalls,AFN/Reachability for network detection,However, the problem is that before the user decides to authorize, The results returned by the detection do not have a network. Unlike the enumeration of camera/album permissions, there is a pending status.), So that the timer continues to initiate network detection.

The problem arises:
After the user does not allow network behavior, AFN/Reachability still returns the result of no network connection.

Solution:

Here, before the timer, You need to customize a prompt box, which will inevitably pop up. the pop-up box is used to prompt the user and guide the user to redirect settings to solve the network problem on their own.
After the user selects the authorization or denied authorization option, the system checks the network connection status. If the connection is established, the system interacts with the data and removes the custom pop-up box. If the user refuses to grant permissions, the pop-up box is displayed.

Note: The pop-up box of the China Mobile Phone System will inevitably cover all the pop-up boxes.
