当从Xib加载UIVied时，loadNibNamed（）崩溃

我想通过使用代码从一个笔尖加载包括UITableView的视图：

class HintTable:UIView, UITableViewDataSource, UITableViewDelegate{ var searchResults = Array<String>() let delegate:MovableAnnotationDelegate @IBOutlet var myTableView:UITableView! init(frame: CGRect, delegate:MovableAnnotationDelegate) { self.delegate=delegate super.init(frame: frame) loadViewFromNib () } required init?(coder aDecoder: NSCoder) { self.delegate=InArrivoHDViewController.sharedDetailController() super.init(coder: aDecoder) loadViewFromNib () } func loadViewFromNib() { NSBundle.mainBundle().loadNibNamed("HintTableView", owner: self, options: nil) self.myTableView.backgroundColor=UIColor(red:0.2890625, green:0.75390625, blue:0.3046875, alpha:0.5) self.backgroundColor=UIColor(red:0.2890625, green:0.75390625, blue:0.3046875, alpha:0.5) print("myTableView %@", self.myTableView); self.myTableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "cell") } } 

然而它却没有任何暗示，

 NSBundle.mainBundle().loadNibNamed("HintTableView", owner: self, options: nil) 

在Xib中，我将该类设置为文件的所有者，而不是在身份检查器中获取它。 我也很不清楚如何访问tableView，因为IBOutlet似乎没有连线。

这是一个crashlog：

Answer 1

我最终将视图插入到Storyboard的主ViewController中，并将委托和源代码适当地分配给View。
