[SOLVED] How to extend QIOSApplicationDelegate with category on ios?

vkjr

Hi!

I have qt application for iOS and trying to add functions to application delegate. Guys on "this link":http://www.cutehacks.com/blog/2014/06/06/using-qt-to-build-an-omi-app-for-ios-and-android suggest to use categories to extend QIOSApplicationDelegate with own functionality.
Like this:

@#import "QIOSApplicationDelegate+OmiAppDelegate.h"
#import <FacebookSDK/FacebookSDK.h>

@implementation QIOSApplicationDelegate (OmiAppDelegate)

(BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
return [FBAppCall handleOpenURL:url sourceApplication:sourceApplication];
}

@end@

But when I write own category I'm getting error that QIOSApplicationDelegate is unknown.
What header or plugin should I include to make it known? (I searched for "qiosapplicationdelegate.h" on hard drive but didn't find it).

Thanks!

Hi,

QIOSApplicationDelegate is in qtbase/src/plugins/platforms/ios

Thank you, I just copied this and one more header to the project and it works :)

Beware that's pretty dangerous, next iteration of Qt might have this header changed so you might end up with an "invalid" delegate

Sure, I understand, thank you!

You're welcome !

Since you have your delegate working now, please update the thread title prepending [solved] so other forum users may know a solution has been found :)

If somehow has the same problem. It sufficies to add this code instead of copying/including the private header:

@interface QIOSApplicationDelegate
@end

Complete Code:

In the .pro:

    ios {
        OBJECTIVE_SOURCES = ios/ios_app_delegate.mm
    }

In ios/ios_app_delegate.mm:

#import "UIKit/UIKit.h"

@interface QIOSApplicationDelegate
@end

@interface QIOSApplicationDelegate (WoboqApplicationDelegate)
@end

@implementation QIOSApplicationDelegate (WoboqApplicationDelegate)

- (BOOL)application:(UIApplication *)application
    didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    NSLog(@"launch!");
    return YES;
}


@end
