So I am doing some PDF rendering and in a spot where I draw some text in a rect (NSString's drawInRect:withAttributes), I get an exception breakpoint triggered, but if I hit continue it moves on and everything works fine. I can't figure out why this is happening. The exception seems like it hits multiple times (I have to hit continue three times) but it is only executing that line once (it's not in a loop). How can I figure out what is causing this? Thanks!
