Obtaining data sent through custom URL scheme

Unity Engine
,

It is common to register a custom url for an iOS app and then launch the app using that url scheme. For example:
myapp://?data1=blue&data2=green
would launch the app bound to “myapp” and provide the data string “?data1=blue&data2=green” when the app is launched.

What is the best way to obtain that data string in Unity? Is there built in functionality for something like this? I see that AppController and iPhone_target2AppDelegate in the iPhone project both implement AppDelegate, but neither implements handleOpenURL.

Is it best to override these as a post process in my build? Has anyone else come up with a good way to handle this?

@Warren, the easiest way is to make a category on AppController that handles the method.

Thanks, Prime31. I’m using a post build process script to add a method to the AppController and that seems to be working. I think I can store the data in global variables and then read them back out through a plugin.

I need to accomplish the very same thing. Could you provide a little more detail on how you did this?

edit: the bellow code indeed works, as long as you don’t have another plugin conflicting with it (for me, it was social networking plugin). then just check “url” in playerprefs.

I’d love a working example, too. I thought I’d gotten it working a couple weeks ago, but now I can’t get it to do anything when it launches via url

In AppController.mm after didFinishLaunchingWithOptions’s stuff I put this in

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url
{
	
    if (!url) {  return NO; }
 	
    NSString *URLString = [url absoluteString];
    [[NSUserDefaults standardUserDefaults] setObject:URLString forKey:@"url"];
    [[NSUserDefaults standardUserDefaults] synchronize];
    return YES;
}

Should this work?

Well, it appears that my code SHOULD work. Got it working easily in a fresh project, but something must be conflicting now.

edit: I can stop pulling my hair out now – found that social network plugin was nullifying my code. found where it handles it in FacebookManager.mm and added what I needed there.

I know its been a while, but can you remember what you did exactly?

I’m having the exact same problem and can’t find the offending code (Obj.C newbie).

If i remember correctly, facebookmanager.mm has a handleOpenURL() that you can use

Hi,

I can not get this to work.
I revived an old thread - http://forum.unity3d.com/threads/99323-Start-iOS-App-with-arguments-and-access-them-within-Unity

Any advice is appreciated.
