"iOS development"-canopenurl:failed for URL: "XX"-Error: "This app is not allowed to query for scheme XX"

is the output of the console after I launch a Xcode 7 + IOS 9 App.

This is not the case in Xcode 6.4 + IOS 8 o'clock, because "in order to enforce enhanced data access security, iOS9 defaults to changing all HTTP requests from, and from, to NSURLConnection CFURL NSURLSession HTTPS requests: IOS9.X-SDK compile, default NSURLConnection CFURL NSURLSession The TLS 1.2 (SSL 3.1) protocol is used uniformly for all HTTP requests from, and to be issued. 】

Here's the solution:

① If your output message is a-canopenurl:failed for URL: "Kindle://home"-Error: "The This app was not allowed to query for scheme Kindle"

Go to the Enable Bitcode under the Build Settings in your target and set it to NO, which will not necessarily prevent your console from continuing to output this message, but it will ensure that your App works.

② If your output message is Xxxx-error: "The This app was not allowed to the query for scheme xxxx"
(here because my App integrates the functions of sharing to QQ, Weibo, xxxx Part I saw Mqq, WeChat, Sinaweibosso and many other information)

Go to info.plist inside to create a called Lsapplicationqueriesschemes Array, the XXXX part of the words you see in one fill in, until the console does not have any relevant output.

③ about other console error messages raised through WebView access to HTTP URLs

As we said earlier, Apple wants us to access a relatively secure HTTPS, so when you need to access HTTP,
Although Apple does not recommend it, it is possible to reverse an unsecured network request by declaring the content shown in Info.plist, which still allows the APP to access the specified HTTP, or even arbitrary http.
