    In your case, it's not as complicated as the link you found.

    Change the file extension of your cpp class implementation to .mm and in the function you want to make the check call, something like:

    NSURL *url = myUrl.toNSUrl();
     bool canOpen = [[NSApplication shared] canOpenUrl: url];

      How we can access to UIApplication? and how can call canopenurl?

      Target is iOS using Qt.

        It's written on the page you are linking as well as the URL: use the UIKit framework.

          @SGaist said in UIApplication.shared.canOpenURL implements in Qt:

          UIKit

          I don't know how to use UIKit, UIApplication in my Qt project.
          I cannot find any solution and sample code for this.
          Can you help me?

            The exact same as you did with NSApplication, just use UIApplication in place.

              Thank you so much for your message.

              Also how we can access to shared object when we are in another file?

              It's a globally object in OBJECT C (.mm) files?

                The same way you did there. The function returns the singleton app instance.

                    The code you pasted does not match the code you are showing in the image.

                    One uses shared and the other sharedApplication.

                      Sorry,

                      shared have error: Class method 'shared' not found.

                      So we did used sharedApplication in images.

                      Please check old my message, i did update it.

                        You know that Objective-C/C++ like C/C++ is case sensitive ?

                        It's canOpenURL.
