IOS Baidu map development series-Baidu map cannot be displayed normally

Sometimes this problem occurs when we use Baidu map (for example)

The key to the problem is that the security code of the Baidu map key we applied for does not match the value of bundle identifier in our project.

So there will be a map that only shows a gray grid without a map.

Solution: Set the values of the two to the same

In the project, set the info. plist File

Baidu map key settings page

As a result, Baidu map is displayed normally.

If it still cannot be properly displayed at this time, try running the project in 3G if you are using WiFi kids shoes.

Here, I would like to remind you that you have applied for a key before and that the keys and Baidu map sdks for using it have changed, I just keep the previous key without looking at the API instructions, and the map cannot be displayed normally.
