Crash when process pixel after crop an image

CGImageRef imageRef = CGImageCreateWithImageInRect([self.imageInput CGImage], rect);
UIImage *result = [UIImage imag         


        

Answer 1

after a long time find solution for this crash. I got an experience: - When process bitmap on iOS: if we don't notice orientation of image, maybe we got some strange crash.

With my crash above: I have fixed it very simple: change

UIImage *result = [UIImage imageWithCGImage:imageRef];

by

UIImage *result = [UIImage imageWithCGImage:imageRef scale:self.imageInput.scale orientation:self.imageInput.imageOrientation];
