This avoids the issue of having a different string in a different module and
relying on details of your compiler and its optimizer. However, it can still

I just noticed that the most recent build of my app was scrolling the image

A web application has a bunch of urls, each connected to a different function.
Define an url to set a parameter and connect it to the function that sets this
parameter. Use this url only in the iOS application. You may want to use some
authentication protocol to authorize the parameter setting,
Thanks for your reply. I'm not sure I'm following, though. Do you mean to
send it query strings? I could make the HTML page of the app a PHP page. If

Just write some http app on the laptop, and hit it with requests (urls) from
the iOS app; this would be the Q&D way to do it easily and with some level of
security (https).
Since you already have a web app, you can just add some admin requests to it.

Basically then, I must not use address pointed to, but instead, the address of
the pointer itself.
I liked the readability of using a string, but I think there is too much room

Thats a neat trick. It’s not an initialisation that I have seen before and on
first glance I thought it was a typo but it works.
