[Interest] [ iOS ] How implement didFinishLaunchingWithOptions to open file associated with MyWidgetApp from another app?

[Edward Sutton]

Thank you Ben,

Categories works!

I do not understand how.  No header file and it somehow works without having to initialize it to the instance of UIApplication.

I put a breakpoint in openURL.  When I open an email attachment, my app is launched, and the breakpoint is hit.  Magic.


#include <UIKit/UIKit.h>

#include "qiosapplicationdelegate.h"
#import "cmsapplicationdelegate.h"

@implementation QIOSApplicationDelegate (CmsApplicationDelegate)

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url
                                       sourceApplication:(NSString *)sourceApplication
                                              annotation:(id)annotation
{
    Q_UNUSED(application);
    Q_UNUSED(annotation);

    NSLog(@"sourceApplication: %@",sourceApplication);
    NSLog(@"url: %@",url);
    return YES;
}
@end

I added an INCLUDEPATH to my project file.

ios {
    QTBASE=$$clean_path($$QMAKE_QMAKE/../../..)/Src/qtbase
    INCLUDEPATH += $$QTBASE/src/plugins/platforms/ios

Thank you Ben!

Objective-C provides a feature called category which could override any class even you don't have the header file. So you just need to override the openUrl of QIOSApplicationDelegate.

Thank you for the links Robert.


How would you hook into the application openURL from a Qt widget app?



- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
    // handle the URL here
}

“Open in MyApp” now shows when email attachment.  My app launches.  I think I just need to figure out how to implement  application openURL for a Qt widget app.

Thank you very much for your time,

For example, the user receives a "report.myapp" file in Apple Mail app as a
file attachment.

When user opens the file attachment, how do you offer "Open in MyWIdgetApp”
as one of the choices?  Has anyone figured out how to do this or found an
example?

Hi Ed,

Not sure if I fully understand your question but as an attempt:
