Yesterday, Passie voor Horeca 1.1 and Passie voor Horeca Lite 1.2 got accepted as update by apple. Two weeks ago, KookJij 1.4 also got accepted which in all cases fixed several bugs when running with iOS4.
With the KookJij app the main issue was a buggy imageloader class which loads thumbnails in a threaded way when scrolling through lists. This same class was used in the Passie voor Horeca apps. They all resulted in UIImages being loaded very slowly.
In the end I decided to rewrite the class from scratch.
Another issue with the Passie voor Horeca apps, was the major change in the MPMoviePlayerController, in iOS4 this class has been deprecated and was replaced by the MPMoviePlayerViewController class in iOS4. Hence some detection on the running OS version on iPhones is now in place, < 3.2 gets the old videoplayer, 3.2 (iPad) and higher gets the video player.
