Question

我正在尝试使用代码加载包含来自笔尖的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")

}
}

然而它在命令中没有任何暗示而崩溃：

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

在Xib中，我将类设置为File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。

这是一个崩溃日志：

Answer 1

我最终在Storyboard的主ViewController中插入视图，并将委托和源适当地分配给View。

从Xib加载UIVied时，loadNibNamed（）崩溃
