Question

Using MonoTouch to develop my very first iPhone application for a customer, I’ve overridden the UITableViewDataSource.SectionIndexTitles function to provide a string[] array with what I thought would make the letters in the vertical band.

Currently I’m facing a working index band but without any characters displayed:

(I do think the UITableViewDataSource.SectionIndexTitles has the native counterpart sectionIndexTitlesForTableView).

My question:

Can someone give me a hint on what I might be doing wrong here?

I do not have all A-Z characters but some characters missing, maybe this could be an issue?

This is a bug in MonoTouch. A workaround is to create a new method in your table source class and decorate it with the Export attribute, passing the native ObjC method to override (sectionIndexTitlesForTableView:):

string[] sectionIndexArray;
//..
[Export ("sectionIndexTitlesForTableView:")]
public NSArray SectionTitles (UITableView tableview)
{                   
    return NSArray.FromStrings(sectionIndexArray);
}
