Alright, I found that project, but as far as I can tell it doesn’t have a way to get the URL.

Everyone agrees on this except Geoff it seems. I had a feedback case for adding the missing Application events that got closed recently.
I think the most recent version of ImprovedIOSApplication is here:
Just copy that class out, the modules folder present wont be up to date. It uses some framework hacks that Xojo says are dangerous but work fine, which is why its not in iOSKit.
I dont have access to Xojo right now. But if you post the event signatures I can probably point you in the right direction.
Jason, that’s the problem. I really have no idea what event signatures I’m looking for.
Initially I thought that there would be an additional event like in a desktop app.
I’ve been looking through Apple documentation all morning, but I get lost in that stuff (I’m a Xojo programmer, not an apple programmer).
Havent tested this, but I believe the following should be approximately what you need. Basically when the app opens you register for a notification that fires if you received a URL. You have to add a handler that receives the callback, and then cleanup code as well so you don’t get a memory leak.
[code]
// in open event
declare function addObserver selector “AddObserverForName:object:queue:usingBlock:” lib FoundationLib (obj_id as ptr, name as CFStringRef, obj as ptr, queue as ptr, block as ptr) as ptr
declare function defaultCenter selector “defaultCenter” lib FoundationLib (clsRef as ptr) as ptr
//declare blk as an iOSBlock instance property
//declare obsRef as Ptr instance property
blk = new iOSBlock(AddressOf NotificationCallback)
obsRef = addObserver(defaultCenter(NSClassFromString(“NSNotificationCenter”)), “UIApplicationDidFinishLaunchingNotification”, nil, nil, blk.Handle)
//in close/deactivate event
declare sub removeObserver selector “removeObserver” lib FoundationLib (obj_id as ptr, obs as ptr)
declare function defaultCenter selector “defaultCenter” lib FoundationLib (clsRef as ptr) as ptr
removeObserver(defaultCenter(NSClassFromString(“NSNotificationCenter”)), obsRef)
obsRef = nil
// new method
sub NotficationCallback(notification as ptr)
declare function getUserInfo selector “getUserInfo” lib FoundationLib (obj_id as ptr) as ptr
dim userInfo as new NSDictionary(getUserInfo(notification))
//access userInfo like the user Info dict from before to initialize the URL/document :)
end sub[/code]
Thanks Jason,
I’m struggling with this. I fixed the declares (lib I he wrong place).
this line won’t compile because the call back ptr is not an object blk = new iOSBlock(AddressOf NotificationCallback)
I assume I should dadd this as a property on the app class? obsRef
Finally, there is no close or deactivate event on an iOSApplicaiton, so I cannot add the code recommended.
Xojo staff? This should be easier 
Yes need to add blk as iosblock and obsRef as Ptr to the app as properties. The close event is from the improved iOS application class
I am so sorry to labor this, but there are two issues.
This raises an exception blk = iOSBlock( AddressOf NotficationCallback)
“Delegate cannot be cast to iOSBlock”
And The version of ImprovedIOSApplication that I have does not implement the closed event. Perhaps there is a newer version out there? I downloaded the one you referenced.
You need to have a NEW before iOSBlock. And the event is WillResignActive for close 
Ahhhhhhhhhhh…
So I have “new” in there, but now it crashes hard on the following line.
I added the bulk and obsRef to the app class. I assume that’s ok?
obsRef = addObserver(defaultCenter(NSClassFromString("NSNotificationCenter")), "UIApplicationDidFinishLaunchingNotification", Nil, Nil, blk.Handle)
Open the console app and send the crash log please
I think this Is the relevant part.

It does help
In the declare for addObserver, remove the capitol A: “addObserverForName:object:queue:usingBlock:” instead
Not quite there yet.

Whoops I switched things in my head. You need to also change this declare to
declare function getUserInfo lib FoundationLib selector "userInfo" (obj_id as ptr) as ptrClose, but no cigar (yet)
I had this working in the open event. Should I be doing it the same here (the part where I get the URL from the incoming ptr?
I’m wondering if we need to check if the key exists before trying to get it. It bombs on the line:
Var k As New Foundation.NSString( "UIApplicationLaunchOptionsURLKey" )The code looks like this (Mostly yours)
[code]Public Sub NotificationCallback(notification as ptr)
Declare Function getUserInfo Lib FoundationLib selector “userInfo” (obj_id As ptr) As ptr
Dim userInfo As New NSDictionary(getUserInfo(notification))
//access userInfo like the user Info dict from before to initialize the URL/document
Dim d As New Foundation.NSDictionary(notification)
Var k As New Foundation.NSString( “UIApplicationLaunchOptionsURLKey” )
Dim fileURL As New Foundation.NSURL(d.Value(k))
Var t As Text = fileURL.path
// get the file…
End Sub
[/code]
Crash looks ike this:

Yes, kinda
The Value function returns “nil” if the key is not present. Probably good to check for that. The quick examples I type up don’t have error checking 
The issue with your code is:
Dim d As New Foundation.NSDictionary(notification)The userInfo dictionary is “d” from before. Just remove this line and change where you read the key from “d” on the next line.
That was just a mistake on my part. Thanks.
Crashing here on the removeObserver line.

Another declare typo. Should be “removeObserver:” <- note the colon
