UIApplication.shared.canOpenURL implements in Qt

SGaist

Are you building for macOS or iOS ?

I built successfully for macOS but you seem to target the simulator.

Max Base

We want this for iOS (iphone). @SGaist

SGaist

From the documentation, NSUserNotification is a macOS API that is not deprecated.

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

Target is iOS using Qt.

https://developer.apple.com/documentation/uikit/uiapplication/1622952-canopenurl

SGaist

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

Max Base

@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?

SGaist

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

Max Base

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

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

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?

SGaist

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.

AppKit is a macOS only framework. Don't link to it when building for iOS.
