数组索引超出范围

Question

我已经成功构建了一个搜索功能，它在detailviewcontroller中搜索并显示TableView标题和副标题。在detailviewcontroller中有两个文本标签，一个用于标题，一个用于字幕。

在单元格中显示标题和字幕效果很好，包括点击并在detailviewcontroller中看到它们。但在搜索功能的应用程序崩溃打字因时：

fatal error: Array index out of range (lldb)

EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)

这里是我的所有代码：

let quotes = [ 
    "Saying1", 
    "Saying2",]//End 

let persons = [ 
    "Name1", 
    "Name2", 

]//End 

var filteredQuotes = [String]() 
var filteredPersons = [String]() 
var resultSearchController = UISearchController() 

    override func viewDidLoad() { 
     super.viewDidLoad() 

     self.resultSearchController = UISearchController(searchResultsController: nil) 
     self.resultSearchController.searchResultsUpdater = self 

     self.resultSearchController.dimsBackgroundDuringPresentation = false 
     self.resultSearchController.searchBar.sizeToFit() 

     self.tableView.tableHeaderView = self.resultSearchController.searchBar 

     self.tableView.reloadData() 


override func numberOfSectionsInTableView(tableView: UITableView) -> Int { 
    // #warning Incomplete implementation, return the number of sections 
    return 1 } 

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
    // #warning Incomplete implementation, return the number of rows 

    if self.resultSearchController.active 
    { 
     return self.filteredQuotes.count 
    } 
    else 
    { 
     return self.quotes.count 
     } 

} 

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 

    let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as UITableViewCell? 

    if self.resultSearchController.active 
    { 
     cell!.textLabel?.text = self.filteredQuotes[indexPath.row] 
     cell!.detailTextLabel?.text = self.filteredPersons[indexPath.row] //THE ERROR OCCURS HERE 
    } 
    else 
    { 
     cell!.textLabel?.text = self.quotes[indexPath.row] 
     cell!.detailTextLabel?.text = self.persons[indexPath.row] 
    } 

    return cell! 
} 

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 
    if segue.identifier == "SendDataSegue" { 
     if let destination = segue.destinationViewController as? SearchDetailViewController { 

      let path = tableView.indexPathForSelectedRow 
      let cell = tableView.cellForRowAtIndexPath(path!) 
      destination.viaSegue = (cell?.textLabel?.text!)! 
      destination.viaSeguePerson =(cell?.detailTextLabel?.text!)! 
     } 
    } 
} 

override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { 
    _ = tableView.indexPathForSelectedRow! 
    if let _ = tableView.cellForRowAtIndexPath(indexPath) { 
     self.performSegueWithIdentifier("SendDataSegue", sender: self) 
    } 

} 


func updateSearchResultsForSearchController(searchController: UISearchController) { 

    self.filteredQuotes.removeAll(keepCapacity: false) 
    self.filteredPersons.removeAll(keepCapacity: false) 

    let searchPredicate = NSPredicate(format: "SELF CONTAINS [c] %@", searchController.searchBar.text!) 

    let Quotesarray = (self.quotes as NSArray).filteredArrayUsingPredicate(searchPredicate) 

    self.filteredQuotes = Quotesarray as! [String] 

    let Personsarray = (self.persons as NSArray).filteredArrayUsingPredicate(searchPredicate) 

    self.filteredPersons = Personsarray as! [String] 

    self.tableView.reloadData() 
}

由于@Larme和@Fogmeister建议，你可以用一个结构数组改善这一点 - 这里的一个你如何做这个部分的例子。

定义一个结构持有这样

struct Quotes 
{ 
    var person : String 
    var quote : String 
} 

和INITIALISE像这样

let quotes = [Quotes(person: "name 1", quote: "saying 1"), 
       Quotes(person: "name 2", quote: "saying 2") ] 

您的数据或者，当然，你可以初始化一个空数组，然后追加数据你可以从某个地方检索它 - 数据库或用户输入

var quotes : [Quotes] = [] 

let quote1 = Quotes(person: "name 3", quote: "saying 3")   
quotes.append(quote1) 

或

quotes.append(Quotes(person: "name 4", quote: "saying 4"))
