  1. Goal: I have configured my app to be opened by some links in iOS, like myapp://lala (using custom scheme), or https://myapp.com/c/lala using universal links, and is already opening my app, but i need to know which url that opened my app. (There is even a tutorial in FMX Express) Problem: I'm trying to handle incoming url from my ios app unsuccessfully. On iOS this should be done by capturing event TApplicationEvent.OpenURL like: procedure TipUrlHandler.ApplicationEventMessageHandler(const ASender: TObject; const AMessage: TMessage); begin case TApplicationEventData(TApplicationEventMessage(AMessage).Value).Event of TApplicationEvent.OpenUrl: HandleUrl(TiOSOpenApplicationContext(TApplicationEventData(TApplicationEventMessage(AMessage).Value).Context).URL); else end; end; Mas o TApplicationEvent.OpenUrl nunca é chamado. So I checked the class TApplicationDelegate in the unit FMX.Platform.iOS.pas in which the TApplicationDelegate.applicationOpenURLWithOptions function should be called every time the app is opened by a url as Apple documents: https://developer.apple.com/documentation/uikit/uiapplicationdelegate/1623112-application?language=objc class function TApplicationDelegate.applicationOpenURLWithOptions(self: id; _cmd: SEL; application: PUIApplication; url: Pointer; options: PNSDictionary): Boolean; So I went to check if the applicationOpenURLWithOptions method is being added correctly in TApplicationDelegate.CreateDelegateMetaClass: class procedure TApplicationDelegate.CreateDelegateMetaClass; begin ... // Opening a URL-Specified Resource if TOSVersion.Major >= 9 then class_addMethod(DelegateClass, sel_getUid('application:openURL:options:'), @applicationOpenURLWithOptions, 'B@:@@@@') else ... end; And then I was able to prove it wrong! The number of arguments declared is wrong, as the correct one should be B@:@@@ Then I made the modification to FMX.Platform.iOS.pas, being as follows: class procedure TApplicationDelegate.CreateDelegateMetaClass; begin ... // Opening a URL-Specified Resource if TOSVersion.Major >= 9 then class_addMethod(DelegateClass, sel_getUid('application:openURL:options:'), @applicationOpenURLWithOptions, 'B@:@@@') else ... end; But the TApplicationDelegate.applicationOpenURLWithOptions function is not yet called. What is wrong? @EDIT Sorry! It is working for custom schemes like "myapp://lala" (with or without the correction in FMX.Platform.iOS.pas) but it is not working for universal links like https://myapp.com/c/lalala. Although I have already configured the universal link correctly and when I click on this universal link, the iOS open my app, but the url can't be handle with TApplicationEvent.OpenUrl, but I discovered that the handling of incoming url of a universal link is different: Handling Universal Links
  2. Hi, I need to rotate the screen at runtime when I open a form. Until the release of IOS 13 this code worked perfectly: procedure ChangeOrientation(toOrientation: UIInterfaceOrientation; possibleOrientations: TScreenOrientations); var win : UIWindow; App : UIApplication; viewController : UIViewController; oucon: UIViewController; begin Application.FormFactor.Orientations := []; //Change supported orientations App := TUIApplication.Wrap(TUIApplication.OCClass.sharedApplication); win := TUIWindow.Wrap(App.windows.objectAtIndex(0)); //The first Windows is always the main Window App.setStatusBarOrientation(toOrientation); {After you have changed your statusbar orientation set the Supported orientation/orientations to whatever you need} Application.FormFactor.Orientations := possibleOrientations; viewController := TUIViewController.Wrap(TUIViewController.alloc.init);//dummy ViewController oucon := TUIViewController.Wrap(TUIViewController.alloc.init); {Now we are creating a new Viewcontroller now when it is created it will have to check what is the supported orientations} oucon := win.rootViewController;//we store all our current content to the new ViewController Win.setRootViewController(viewController); Win.makeKeyAndVisible;// We display the Dummy viewcontroller win.setRootViewController(oucon); win.makeKeyAndVisible; {And now we Display our original Content in a new Viewcontroller with our new Supported orientations} end; However, since the release of IOS 13 the screen locks on the set orientation but does not rotate. So if I set Landscape orientation the screen remains in Portrait orientation until I physically turn the phone around, at which point it rightly remains locked on that orientation. This is a real disaster because then, until the phone is turned, all the controls ( finger position, object position,..) are wrong.
