Variation between iOS 6 & 7 in displaying?


I’m learning with this great book, but somehow I couldn’t solve an issue in this chapter.

In the detail view, I could display the all text fields and labels nicely in iOS 6. However, not in iOS7. It seems like the detail view can’t be placed nicely under the navigation bar.

Might I know what goes wrong here? How can I fix it? Thanks.
