Question

我需要一个搜索栏来查看我的桌面视图，但我是一个初学者，而且我很开心。

在我的表格视图中，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：为了使它更容易和更有条理，我创建了一个枚举，并希望用它来命名这些部分。

我已经举了一个例子来说明我已经达到了多远：

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：当用户点击他选择的行时，他将被发送到一个UIViewController，它将显示名称，年份和描述。在这个例子中，我没有在这里创建一个prepareForSegue。

提前致谢。

Answer 1

我会考虑您遵循此Link

我在我的项目中使用它并且非常容易实现和维护。您必须管理两个数组结果：

<强> 1。与搜索文本匹配

<强> 2。没有任何搜索文本

重新加载表格部分，然后超时输入您输入的文字。

如果你在实施它时遇到任何问题，请告诉我。

Answer 2

我建议使用一系列电影和过滤电影。数据源应该是过滤后的电影，默认情况下是电影。使用搜索字段搜索字段时，应根据搜索字段上的文本过滤符合条件的电影数组。然后，您应该重新加载tableview的数据，并且只应显示您的搜索项。根据您希望如何实现它，可以在每次更改文本字段或停止编辑或返回时完成。

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

func yourTextfieldDelegate(textField: Textfield) {
    if textField.text.characters.count == 0{
        self.filteredMovie = self.movie
    }
    else{
        // for example, filter by name
        self.filteredMovie = movie.filter($0.data.name.lowercase.contains(textfield.text.lowercase))
        self.tableViewRef.reloadData()
    }

}

ps：你错过了tableView的插座。我称之为tableViewRef。
