That’s not what I see. I made a quick experiment, with the stock Cocoa/AppKit
template. I dropped a text field into the window, and a button to trigger an
alert. doAlert: harvests the informative-text string from the field, which
means the string can vary.
Everything else is the same as your code (stripped of the accessory view, which
you describe as being merely an attempt to work around the failure of the
informative text to appear). Note that you should set the informative-text
format to the string you want to display; use %@ and then the string.
What this suggests to me is that your “informativeText” variable is not what
you assume it is. Have you set a breakpoint before you create the alert, and
inspected it?
