Question

我正在尝试在PFQueryTableViewController上实现UISearchBar。我就是这样做的：

var filteredTableData = NSMutableArray()
var resultSearchController = UISearchController()

required init(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)

    // Configure the PFQueryTableView
    //self.parseClassName = "Collections"
    self.textKey = "username"
    self.imageKey = "profileImage"
    self.pullToRefreshEnabled = false
    self.paginationEnabled = true
    self.objectsPerPage = 20

        self.resultSearchController = UISearchController(searchResultsController: nil)
        self.resultSearchController.searchResultsUpdater = self
        self.resultSearchController.dimsBackgroundDuringPresentation = false
        self.resultSearchController.searchBar.sizeToFit()
    self.navigationItem.titleView = self.resultSearchController.searchBar
}

如果我将控制器添加到self.navigationItem.titleView，当我开始编辑时，搜索栏会向上滑动，导航栏会消失。如果我改为：

self.tableView.tableHeaderView = self.resultSearchController.searchBar

应用程序崩溃了：

- (void)loadView {
    [super loadView];

的PFQueryTableViewController.m

访问标题视图时PFQueryTableViewController崩溃
