Have encountered a problem before.
Is the use of storyboard dragged out of the control, iOS7 on the run is always inexplicable move down.
For example (the red area is redundant)
The workaround:
IOS7 has added this attribute in Conttoller:
Automaticallyadjustsscrollviewinsets, when set to Yes (default Yes), assume that there is only one uiscrollview or its subclass view inside the view. Then it will set the corresponding padding on its own initiative. This allows scroll to occupy the entire view without obscuring the navigation bar.
We can fix the problem by setting the Automaticallyadjustsscrollviewinsets property to No.
For example, the following:
Of course, you can also do this by changing the Uiviewcontroller Edgesforextendedlayout property.
Self.edgesforextendedlayout = Uiextendededgenone;
