可能是您的内容少于ScrollView ，这就是禁用滚动的原因

Answer 3

Put view with labels in scrollview. Scrollview should be less in height than view. View should have height considering all ui cvontrols in it. should work like this

Answer 4

Make sure your scroll view height is not greater than view its content size has to be greater as all people says. You get confused between content size and scroll view height. Meas using nib suppose your scroll view height is 300 and when you use the code content size should be greater than 480 so it will be scroll-able on iPhone 4 size device who's height is 480

Answer 5

To make sure your constraints are well defined, first check these steps:

• Make sure your base view is a UIView
• Put into a UIScrollView and add constraints to the edges of UIView
• Put into the scrollview a UIView and add constraints to the edges of the scrollview. I call this "content view".
• You should assign a width to the content view. I usually set the width of the content view equal to the width of the scrollview.
• Put your labels/views/images/whatever into the content view and use autolayout constraints to resize them automatically to fit the target screen.

Please consider that:

• Your scrollview must always have a height, fixed or dynamic. In order to avoid errors with autolayout, consider that:
  • the last element on the bottom of the content view must always have a constraint to the bottom edge of the scrollview, or
  • the content view must have a fixed height
• If the height of your content view is less than the height of the scrollview, the view will not scroll. You should add more views or more margin to the bottom constraint of the content view.
