UIScrollView not scrolling

by

It’s always good to show a complete working code snippet:

// in viewDidLoad (if using Autolayout check note below):

UIScrollView *myScrollView;
UIView *contentView;
// scrollview won't scroll unless content size explicitly set

[myScrollView addSubview:contentView];//if the contentView is not already inside your scrollview in your xib/StoryBoard doc

myScrollView.contentSize = contentView.frame.size; //sets ScrollView content size

Swift 4.0

let myScrollView
let contentView

// scrollview won't scroll unless content size explicitly set

myScrollView.addSubview(contentView)//if the contentView is not already inside your scrollview in your xib/StoryBoard doc

myScrollView.contentSize = contentView.frame.size //sets ScrollView content size

I have not found a way to set contentSize in IB (as of Xcode 5.0).

Note:
If you are using Autolayout the best place to put this code is inside the -(void)viewDidLayoutSubviews method .
