Question

I have a vertically scrolling uiscrollview – imagine an ‘about this app’ page of a tab bar app which goes on a bit and requires a scrollview. It only contains a few images, a video and some text (only the video has been coded in – the rest have been placed in the GUI). In storyboard (Interface Builder?) Xcode 4.2, everything is set up as it should be and works fine, but the view is only as large as what you see on the screen, is it not possible to manually arrange in storyboard the items that are initially offscreen – that you need to scroll up to? The only way I’ve found so far is to design them on the visible view then navigate them down with the arrow keys..

Answer 1

I feel your pain. The only way I found is to manually pan the scroll view in the size inspector to reveal the portion of the view that you wish to visually edit.

Use a UIView to contain elements so they are positioned relatively to this view. Add the view as a subview to the scrollview at 0,0.

1. pan: use the Y coordinate say to -200, then edit the contents.
2. to place more contents in the hidden part, pan again to reveal new real-estate
3. when finished, restore the values of the ScrollView’s height and X,Y position.

Make sure the scroll view frame rectangle is smaller than the contained view.
