iOS Control Instantiation problem

[Chris Sheffield]

Console is located in /Applications/Utilities.  You can also debug this way when running your app on a device. Simply open Xcode, and under your connected device, click the Console icon. Note that the Console application is used when you're running in the simulator, and the Console in Xcode is used when running your app on a physical device. Sometimes I get confused and wonder why I'm not seeing output in one or the other. :-)

In one case I had a badly formed statement that compiled without problems - I had put 'to' instead of 'into' - so the rest of the handler was skipped; in another case I had called iPhoneControlSet with a bad parameter, which again caused the script to stop executing.

I seem to have fallen at the first fence. Within a preOpenCard handler for the first and only card in the stack, I use this bit of script which I got from an LC example ('Mobile Scroller Example') which works fine in the 5.1 iPhone simulator on my setup:

Both examples appear to have the same iOS standalone parameters, both compile apparently error-free and the Simulator launches each one quite happily. Nevertheless, I can show that in my case the ID is empty and that there's no sign of the native control appearing on the card. I tried it with a native text control too (iPhoneControlCreate "input") - same result. The control never appears and the ID is empty.
