Problem with running ios sample

[matrix]

Hello all,

First of all I' m new to the Irrlicht-Engine but a beginner on the Mac/ios plattform.

This is my problem:

I´m trying to get the simple HelloWorld example running on the ios-emulator.
I' m using the newest XCode 4.x with the ios sdk 5.2.

I' m adding HelloWorld as a project to the ios-solution where the Irrlicht-lib as a
project exists.
Then I make the settings in the HelloWorld project like the linker settings
the path for the header files and so on.

I can compile the HelloWorld program and link it against the Irrlicht-lib without problems.
The emulator starts (I also get no errors on the Xcode Debug-Window, only status-messages
like "Running on: EGL 1.1 Device and a list of device properties)
but I get no display on the emulator, the screen is black.

What is my problem? Must I write a AppDelegate for the HelloWorld app?

Tanks in advance

Regards
