Answer 1

if you have added constraints properly . then add this

make property or your scrolview and container view as

@property (weak, nonatomic) IBOutlet UIScrollView *scrollview;
@property (weak, nonatomic) IBOutlet UIView *containerview;

then in .m file

@synthesize scrollview,containerview,

then add this

-(void)viewDidAppear:(BOOL)animated
{
    [scrollview setContentSize:CGSizeMake(scrollview.frame.size.width, containerview.frame.size.height)];
}

I hope the will solve your issue.

There is no problem with autolayout in x-code 6.4 just try to check that you have properly bind the outlets of scrollview as well as give contentsize to scrollview that how much you would like to scroll your scrollview.

scrollview.ContentSize = CGContentSize(0, height);

--> Give height as float or integer as how much you want to scroll your scrollview.

Answer 3

For the ScrollView to work, reference it to your .h file by CTRL + Dragging the scroll view, and on your .m file add a

scrollView.contentSize(0,doubleTheSizeOfTheViewHeight);

if you want the scroll to be scrollable horizontally do the same with the width.

Hope this helps

Update Or you can always use this for the storyboard way of doing it: Storyboard UIScrollView contentSize?

要使UIScrollview滚动，您必须取消选中XIB中的“使用自动布局”复选框。
