UIScrollView Issues - Pulling my hair out

[materialised]

Hi all,

I have an issue and I am really pulling my hair out with it.

I have a UIView containing UIScrollView and 2 buttons, which when my application is first ran, occupies a space at the bottom of the UIViewController,
One of these buttons expands the view, and the other collapses it again.

My issue is, that even though I am hard coding 100 items, when I expand the custom view the UIScrollView does not render all of the items.


The above image shows the custom view in the collapsed state


The above image shows the view in the expanded state.


The above image shows the issue I described in which all items are not being rendered to the UI scroll view.

I have created a simple example project that illustrates my problems, it is available to download from http://dl.dropbox.com/u/9930498/ScrollViewTest.zip

If anyone can help me I would be most grateful.

Many Thanks

I'm not completely clear on what you're describing but have you thought of setting the content size of the scrollview once it's expanded?

[<UIScrollView> setContentSize:<CGSize>];

This sets the rectangle you scroll around, not the size of the scroll view. The scroll view is like a window showing you a section of the bigger rectangle.

In case you don't know. You can create a CGSize the same way you create a point:

CGSize *size = CGSizeMake(<CGFloat width>, <CGFloat height>);
