Download and run stacks on iOS

[ctceismc]

Can you download a remote stack and run it on iOS?

[Jellicle]

Yes.

Jellicle... How ?

Hi,

AFAIK you can't open another stack in iOS. This means that it is impossible to download and open a stack in iOS.

Kind regards,

Mark

Mark, I currently have an app on the app store that copies a stack from the app bundle to the iOS documents directory, and, having copied it there, navigates to that stack. I can't see why the app couldn't download a stack and then go to it. All that's different is the means of copying the file.

Or am I missing something obvious?

I think it would work. Mobile apps can only have one stack open at a time, but you can go to any stack. I haven't tried it on mobile, but typically you do it this way:

go stack "http://www.mydomain.com/mystack.livecode"

Hi Jacque,

I tried making a stack with a substack and tested the go stack command on the substack. This didn't work for me.

Kind regards,

Hi all,

doesn't this fall into the category "downloading CODE" which was explicitely fobidden by his Steveness?

[Mark]

Hi Klaus,

Yes, you're right, but it is still an interesting idea to think about (and try)

Kind regards,

Mark

Hi Mark,

Good luck!

Hi...

I can't get it to work either... I can download a stack to the 'documents' folder without a problem, but can't 'go stack' from the one that is already displaying on screen to the one that has just been downloaded... and go stack "http://www.mydomain.com/mystack.livecode" doesn't work for me..

Jellicle, please tell us the secret...

be well,

Dixie

Interesting. The docs specifically say that "go stack" will work. When I get some time I'll test it. You can't use "go stack in window" but a plain "go" is documented to not only be supported, but recommended.

Edited: I got curious so I tried it with a mainstack and a substack. It works fine. The scripts were very simple. A button on the mainstack:

on mouseUp
go stack "mainSub" -- this is the name of the substack
end mouseUp

And a button on the substack:

on mouseUp
go stack "main"
end mouseUp

No problems.

I don't have a stack on my server ready to test with, so that part will have to wait.

Hi,

Since Jacque says it is working, I decided to do some tests in the simulator. Apparently, leaving out "in the window of" does the trick. I was able to go to a different substack and to load a stack from a server. Still, Apple won't like downloading code.

Kind regards,

Mark

Yeah, it's confusing. You can only use "in the window of" in a revlet to go to another stack, and you can't use it at all on mobile. So there are different rules. I'm glad to hear you can download a stack remotely, now I don't have to test it. But you're right the Apple will reject an app for downloading code.

Jellicle, please tell us the secret...

No secret...i just go to the stack
