let overCount: Int=// character limit
var navigationTitle: String?{
    DidSet{
        if var title = navigationTitle {
            if title.count<=overCount{
                navigationItem?.title=title
            } else{
                title=String(title.prefix(overCount))
                title+="…"
                navigationItem?.title=title
            }
        }
