ios - 如何在带有部分的 TableView 上创建搜索栏？

Question

我的表格 View 需要一个搜索栏，但我是初学者，我正在绞尽脑汁去做这件事。

在我的表格 View 中，我有几个部分。每个部分都填充了包含名称和日期的项目。我希望用户能够通过名称进行研究。

还有一件事:为了让它更容易和更有条理，我创建了一个枚举并想用它来命名这些部分。

我已经举了一个例子来展示我已经达到了多远:

class Cinema: UITableViewController {

// MARK: - Properties

var movie:[(type: Genre, data:[Movies])] = []

//MARK: - Super Methods
override func viewDidLoad() {
    super.viewDidLoad()

    movie = [

        (Genre.Action, [

            Movies (name: "Matrix", year: "1999", description: "A computer hacker learns from mysterious rebels about the true nature of his reality and his role in the war against its controllers."),

            Movies (name: "Gladiator", year: "2000", description: "When a Roman general is betrayed and his family murdered by an emperor's corrupt son, he comes to Rome as a gladiator to seek revenge."),

            Movies (name: "Saving Private Ryan", year: "1998", description: "Following the Normandy Landings, a group of U.S. soldiers go behind enemy lines to retrieve a paratrooper whose brothers have been killed in action.")
            ]),

        (Genre.Drama, [

            Movies (name: "Good Will Hunting", year: "1997", description: "Will Hunting, a janitor at M.I.T., has a gift for mathematics, but needs help from a psychologist to find direction in his life."),

            Movies (name: "Schindler's List", year: "1993", description: "In Poland during World War II, Oskar Schindler gradually becomes concerned for his Jewish workforce after witnessing their persecution by the Nazis.")
            ]),

        (Genre.Comedy, [

            Movies (name: "Monty Python and the Holy Grail", year: "1975", description: "King Arthur and his knights embark on a low-budget search for the Grail, encountering many, very silly obstacles."),

            Movies (name: "Hangover", year: "2009", description: "Three buddies wake up from a bachelor party in Las Vegas, with no memory of the previous night and the bachelor missing. They make their way around the city in order to find their friend before his wedding.")

            ])
    ]


}

// MARK: - Table view data source

override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    // #warning Incomplete implementation, return the number of sections
    return movie.count
}

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    // #warning Incomplete implementation, return the number of rows
    return movie[section].data.count
}


override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! ADTableViewCell

    cell.title.text = movie[indexPath.section].data[indexPath.row].name
    cell.year.text = movie[indexPath.section].data[indexPath.row].year

    return cell
}

override func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
    if section == 0 {
        return "Action"
    } else if section == 1 {
        return "Drama"
    } else {
        return "Comedy"
    }
}

P.S:当用户单击他选择的行时，他将被发送到一个 UIViewController，该 UIViewController 将显示名称、年份和描述。在此示例中，我没有在此处创建 prepareForSegue。

提前致谢。

我已经在我的项目中使用过它，并且非常容易实现和维护。您将必须管理两个数组结果:

1. Matched with search text

2. Without any search text

Reload the table section and rows overtime you type a text.

如果您在实现它时遇到任何问题，请告诉我。
