I've just finished porting my application - we're starting beta test
right now. On the way, I've checked for SDK compatibility. It seems
that the whole xmlvm framework is compatible with iPhone SDK >=
2.2.1. Below this the AVFramework is missing which may be a lot
of work to replace - I don't know. A few functions need to be commented
out, e.g. functions for translucency, but these are minor changes.
However for 2.2.1 some internal iPhone math functions seem to be
buggy - a test of the audio analysis kernel gives the expected
result in the emulator, but wrong numbers on the device. So the
version where everything works fine is iPhone OS >= 3.0 .
It is necessary to use the Release build with GCC 4.2 optimization
set to the highest level (= 9) to get about the same execution speed
as on an Android device. With default optimization (= s) it is about
twice as slow on the device. The emulator runs much too fast.
Best,
Alex
