Fatal Error in Upcoming Update #2

Closed peoplecallmefrancois closed 10 years ago

peoplecallmefrancois commented 11 years ago

I received the following error. Thought I should warn you. Great library by the way. :)

CGContextTranslateCTM: invalid context 0x0. This is a serious error. This application, or a library it uses, is using an invalid context and is thereby contributing to an overall degradation of system stability and reliability. This notice is a courtesy: please fix this problem. It will become a fatal error in an upcoming update.

I'm receiving this warning too. Any ideas how to fix it?

The error occurs when the visibleRect is empty. I'm not exactly sure when it happens, but I believe it's as the blur view is going on or off. I added: if(CGRectIsEmpty(visibleRect)) return; near the top of renderLayerWithView and it was all better. Sorry, I'm not very versed in github stuff.

Hello, I come here just confirm that the solution by pizzafilms is working.

Added:

if(CGRectIsEmpty(visibleRect)) return;

After create visibleRect from superview frame.

Thank you very much for saving my time, and Thank to great library.
