iOS get physical screen size programmatically?

Question

Is this possible? I want the number of inches, not the number of pixels. I know it is approximately 160 ppi. But not exactly.

Answer 1

CGFloat scale = [UIScreen mainScreen].scale; CGRect screenRect = [[UIScreen mainScreen] bounds]; CGFloat screenWidth = screenRect.size.width * (scale/100.0f); CGFloat screenHeight = screenRect.size.height * (scale/100.0f);

• scale is persent!
