Hi there. I have to rotate an image continuously and I'm using now CALayers as the image containers and I'm rotating thous CALayers by setting its Transform property. Now I have two approaches to keep rotating these layers. 1) Use a displayLink of 30 fps. Use CATransaction, setting setDisableActi

You can fix this by adding the -ObjC linker flag. See related issue: http://developer.apple.com/library/mac/#qa/qa2006/qa1490.html This will force the linker to load classes from the static library Another way is to reference the class directly somewhere in the code such that it has no effect,
