public class SubtitleTableViewCell : UITableViewCell {
public SubtitleTableViewCell () : this ( typeof ( SubtitleTableViewCell ).
FullName ) {
}
public SubtitleTableViewCell ( string reuseIdentifier ) : base (
UITableViewCellStyle.Subtitle, reuseIdentifier ) {
}
protected SubtitleTableViewCell ( IntPtr handle ) : base ( handle ) {
}
}
If I use a class like this then I get a cell of the default style. If I
don't pass the pointer to base ( handle ) then it uses the subtitle style.
