fmax use in MBCoverFlow
There is a subtle bug in this line:
[_scroller setNumberOfIncrements:fmax([self.content count]-1, 0)];
Namely, the count method returns an unsigned long (NSUInteger), and therefore when count is 0, and you subtract 1, you get an overflow. This can be fixed easily enough by casting to a signed integer:
[_scroller setNumberOfIncrements:fmax(((NSInteger)[self.content count])-1, 0)];
And yes, nine years on I am still using this code in Keyboard Maestro.
Layer intersection error on fast scroll
Hi,
first of all thanks for making MBCoverFlowView open source!
Unfortunately I'm fairly new to CoreAnimation and drawing in 2.5D.
So I'd just like to file a bug report for a bug that happens whenever you rapidly scroll thru the cover flow. (Apple's cover flow does not show this behaviour)
What happens is that neighboring layers (those around the currently selected cover) happen to intersect ("or move/rotate thru") the cover in the very middle, when it rotates to either side.
This is only seen when rapidly scrolling the view!
CGContextClearRect needed after CGBitmapContextCreate
There needs to be a CGContextClearRect( context, gradientRect ) after the CGBitmapContextCreate to clear the context data before drawing the gradients, otherwise the initial state of the memory is incorporated into the fading.
Not working in osx >= 10.9
Does not seems to be work for latest osx versions.
