Objective-c ComboBox customized component - ios

Question

hi i'm creating my own customized ComboBox, i copy on here my code so that anyone can use it. ( i don't know where else to put it lol )
I'd like also to know if you have better idea to improve it.
I get a small error, when i init the instance with the initWithBlurredImage, everything works fine but the blurred image doesn't cover the whole screen, it misses a small frame of about 5px. can you understand why?
