Extra top white space since IOS 8 using autolayout and scrollview

Since the new update to IOS8, i have an extra white space over my contentview in my scrollview.
My content view should be centered in my scrollview and it’s work fine on IOS7.

Here is the result :

  • dataWithContentsOfURL returns NSCocoaErrorDomain Code=256 over cellular, but not wifi
  • Multiplying ints in swift
  • Issue with setting and retrieving the value of AVMetadataCommonKeyCreator
  • Java string encrypt
  • What's wrong here: Instance member cannot be used on type
  • Realm crashes with RLMException: object has been deleted or invalidated
  • enter image description here

    Here is the storyboard version which doesn’t have white space :

    I’m wondering what could cause this extra space, is there anything new in ios8 that will cause my content view to have extra space ?

    Maybe i need to change how i layout my view ?

    Thanks!

    EDIT: My solution was to only uncheck adjust scroll bar inset in my views which had the problem.
    However the solution below that i accepted works too.

    I had this exact same problem, and I came up with two possible solutions, both of which are awful and make me ashamed to be a programmer:

    1. Constrain the scrollable view’s top to the top of the scroll view, but with a constant of -64, which is the height of the extra space. I don’t know why.
    2. Add an empty UIImageView as a sibling of the UIScrollView, and constrain it to be flush with all four sides of the root view.

    I’m hoping that it’s just an iOS 8 bug so that I can take out my hack and step down off the ledge.

    I faced the same issue in iOS 8, following is solution I found:
    – Select View Contoller (in storybord) in which you have added the scroll view
    – In “Property Inspector” in “Layout” section un-check “Adjust Scroll View Insets”

    Try this at your viewDidLoad for that scrollview:

    self.automaticallyAdjustsScrollViewInsets = NO;
    

    untick the Extend Edges: under top bars of the main view and make the top distance of the subview 0 instead of negative value. this works for me.
