Hello,
I am having an issue with the status bar and iAd.
Take the sample iAds code in the sdk and remove the line
display.setStatusBar (display.HiddenStatusBar)
in the main.lua file
On ios 7 devices the status bar is displayed on top of the ad (see screen capture).
For devices prior to ios7 this works fine (the status bar is displayed, and below we have the ad. They do not overlap).
I am building with Version 2013.1256 (2013.11.6)
