iOS app iPhone 5s iOS 7 app display height

Question

I have developed an app for iOS 8 on iPhone 5s using storyboard layout.

But I found that when the system is changed to iOS 7 Display Height Is changed into Does not fit the screen size. iPhone 4s screen size show app interface.

Answer 1

Do you mean ran the app using iPhone5S? By saying "use storyboard layout" did you mean using Autolayout? Probably you are not using Autolayout, or you didn't set the constraints working quiet well.

Here is the reference you may find useful. Copyright reserved by apple. Section “Adaptivity and Layout” in 《IOS Human Interface Guideline》(You can download from iBook).

Also Autolayout Reference. Auto layout Reference provide by Apple

you will find the edit selection at the button of Storyboard editing page.(I don't have the authority to publish picture)

Hope that this may help.
