I don't know exactly what you mean "I can see the black Area". However, the "center image" problem is quite a common one. As far as I know, there is no out of the box way to solve this. Fortunately, there is some great code on github which handels image scrolling in a UIScrollView nicely. See this question and this github project for further information.
