我正在尝试使用第三方库TTFortuneWheel来构建应用。以下代码是我添加到此新项目中的代码。
当我运行该应用程序时，它显示以下错误：EXC_BAD_accESS（code = 2，address = 0x10e5c8dd8）

class ViewController: UIViewController {


    @IBOutlet weak var spinningWheel: TTFortuneWheel!

    override func viewDidLoad() {
        super.viewDidLoad()

        let slices = [ FortuneWheelSlice(title: "Slice 1"),FortuneWheelSlice(title: "Slice 2"),FortuneWheelSlice(title: "Slice 3")]

        let frame = spinningWheel.frame
        let fortuneWheel = TTFortuneWheel(frame: frame,slices: slices)
        spinningWheel.equalSlices = true
        self.view.addSubview(fortuneWheel)

我还尝试了以下代码，该代码是从TTFortuneWheel的示例修改而来的，并在示例项目上成功运行，但是在我的项目中运行时显示了另一个错误：EXC_BAD_accESS（code = EXC_I386_GPFLT）

 let slices = [ FortuneWheelSlice.init(title: "Roller Coaster"),FortuneWheelSlice.init(title: "Try again"),FortuneWheelSlice.init(title: "Free\nticket"),FortuneWheelSlice.init(title: "Teddy\nbear"),FortuneWheelSlice.init(title: "Large popcorn"),FortuneWheelSlice.init(title: "Balloon figures"),FortuneWheelSlice.init(title: "Ferris Wheel"),FortuneWheelSlice.init(title: "Pony\nRide")]
        spinningWheel.slices = slices
        spinningWheel.equalSlices = true
        spinningWheel.frameStroke.width = 0
        spinningWheel.slices.enumerated().forEach { (pair) in
            let slice = pair.element as! FortuneWheelSlice
            let offset = pair.offset
            switch offset % 4 {
            case 0: slice.style = .dark
            case 1: slice.style = .light
            case 2: slice.style = .dark
            case 3: slice.style = .light
            default: slice.style = .dark
            }
        }

我已经尝试解决这些问题一周了，并通读了TTFortuneWheel的所有文件。如果有人能帮助我解决这些错误或帮助我正确使用TTFortuneWheel，我将不胜感激！
