不能"addSubView"

Question

错误 - >'UIVIew'没有名为'addSubView'的成员

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    var testView = UIView(frame: CGRectMake(0, 0, 320, 568))
    testView.backgroundColor = UIColor.redColor()
    self.view.addSubView(testView)
}

Answer 1

我猜,这是由于大写字母'V'.尝试

 self.view.addSubview(testView)
