Swift4 tableView如何优雅的注册cell,获取循环

注册cell示例

tableView.ts_registerCellNib(HomeCell.self)

获取循环利用的cell示例

let cell = tableView.ts_dequeueReusableCell(HomeCell.self)

public extension UITableView {
    // MARK: - Cell register and reuse
    /**
     Register cell nib
     
     - parameter aClass: class
     */
    func ts_registerCellNib<T: UITableViewCell>(_ aClass: T.Type) {
        let name = String(describing: aClass)
        let nib = UINib(nibName: name, bundle: nil)
        self.register(nib, forCellReuseIdentifier: name)
    }
    
    /**
     Register cell class
     
     - parameter aClass: class
     */
    func ts_registerCellClass<T: UITableViewCell>(_ aClass: T.Type) {
        let name = String(describing: aClass)
        self.register(aClass, forCellReuseIdentifier: name)
    }
    
    /**
     Reusable Cell
     
     - parameter aClass:    class
     
     - returns: cell
     */
    func ts_dequeueReusableCell<T: UITableViewCell>(_ aClass: T.Type) -> T! {
        let name = String(describing: aClass)
        guard let cell = dequeueReusableCell(withIdentifier: name) as? T else {
            fatalError("\(name) is not registed")
        }
        return cell
    }
    
    // MARK: - HeaderFooter register and reuse
    /**
     Register cell nib
     
     - parameter aClass: class
     */
    func ts_registerHeaderFooterNib<T: UIView>(_ aClass: T.Type) {
        let name = String(describing: aClass)
        let nib = UINib(nibName: name, bundle: nil)
        self.register(nib, forHeaderFooterViewReuseIdentifier: name)
    }
    
    /**
     Register cell class
     
     - parameter aClass: class
     */
    func ts_registerHeaderFooterClass<T: UIView>(_ aClass: T.Type) {
        let name = String(describing: aClass)
        self.register(aClass, forHeaderFooterViewReuseIdentifier: name)
    }
    
    /**
     Reusable Cell
     
     - parameter aClass:    class
     
     - returns: cell
     */
    func ts_dequeueReusableHeaderFooter<T: UIView>(_ aClass: T.Type) -> T! {
        let name = String(describing: aClass)
        guard let cell = dequeueReusableHeaderFooterView(withIdentifier: name) as? T else {
            fatalError("\(name) is not registed")
        }
        return cell
    }
}
