Actually that did work (I just forgot to link them inside the .xib)! I created a method inside the view controller that displays the actionSheet instead of doing it inside the app delegate.

Thanks for your reply, but I’m still confused…

Let me clarify what I want to accomplish…

I have these files inside a “SampleApp”:
- SampleAppDelegate
- SampleAppViewController

I have a NSString, a button and a label in the “SampleAppViewController”. when you click the button, the application exit and open another application (type URL, or do anything inside that other application). After that, the “SampleApp” relaunch with the URL handled inside the “- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url” method. Then, I want to check the URL string and do different actions inside the “SampleAppViewController” based on the url received. For example, show it on the screen, change the view background color, add it to NSString, show an actionSheet that will be handled inside the “SampleAppViewController”…etc.

I tried to create an instance of the ViewController class in the delegate (and tried to create an instance of the delegate class in the viewController too <– not a smart move, but I tried) and set the NSString inside the ViewController to hold the "message", but the NSString still "nil". Also, the label on the screen still empty.

One more thing, how can I run the debugger again after my application relaunch?

You can create an IBOutlet in the application delegate class, and link that to a view controller in interface builder. Then in the delegate function you can pass the data to that view controller.

This does require that the view controller and application delegate are in the same .xib file.

Is there an easy way to pass these parameters to a view controller that will print them on the screen (not using alert message)! I’m not sure if I should create my own protocol to pass these parameters. I cannot read the values from a different view or update labels views from within this method! (labels are in a view controller, while this method is in the app delegate)

please advice!

I don’t know of such an example. The key is in the receiving application that needs to be able to handle this. If so, any application or web app can start that applications.

Thanks for this info. Do you know of an example where a iPhone web app links to an iPhone native app (of course, not including mail, maps, etc.)? Your post indicates this is possible.

Thanks so much for posting this. I’ve been searching how to take the launchme example to the next level, but until now never found how to parse the parameters properly.
