Re: Releasing a Layer and It's Context

The following code crashes in CGLayerRelease when provided a basic window context (i.e., inContext). Can anybody tell me what's wrong here? According to the documentation, the caller is responsible for releasing the context returned by CGLayerGetContext(). FWIW, it doesn't make any difference if I draw into the layer or not.
.
CGSize layerSize = {100.0, 100.0};
CGLayerRef layer = CGLayerCreateWithContext(inContext, layerSize, nil);
CGContextRef layerContext = CGLayerGetContext(layer);
CGContextRelease(layerContext);
CGLayerRelease(layer);

The routine CGLayerGetContext is a "Get" routine. You are not responsible for releasing something that comes from a "Get" method (only "Copy" or "Create").


Remove the call to CGContextRelease.
