Displaying aggregate values in section headers
posted

Is there a standard way to display aggregate cell values in section headers, aligned with the cell in question, which supports horizontal scrolling, and supports expandable/collapsible sections?

Right now I can almost make it happen by overriding gridView:viewForSectionHeader, and returning a built-up view of UILabels positioned based on the IGCellPath of the first row of cells. However, it doesn't work when there is horizontal grid scrolling; the section header doesn't scroll along with the grid, which kind of makes sense because then how would the section title show.

I could alternatively just change the section title text to something like: "Section A:  AggValue1:123.45   AggValue2:678.90", but that doesn't align up with the cells, which seems to be the limiting issue in all this.

Any other ideas that could work to simulate a section header that shows aggregate cells values aligned with the cell in question, horizontally scrolls well, and supports expandable/collapsible sections?

Thanks.
