Question

通过cocoapods安装库https://github.com/AAChartModel/AAChartKit-Swift之后，我尝试运行存储库中提供的示例。

我遇到以下错误

Thread 1: Fatal error: Unexpectedly found nil while unwrapping an Optional value

..在这些行上（在库中，我没有写过它们）

let path = Bundle.main.path(forResource: "AAChartView", ofType: "html", inDirectory: "AAJSFiles.bundle")
let urlStr = NSURL.fileURL(withPath: path!)

我不知道该如何解决...似乎在构建时资源文件夹没有复制到捆绑软件中。

这是我正在执行的代码：

    let chart = AAChartView()
    chart.frame = CGRect(x: 0, y: 0, width: self.view.frame.size.width, height: self.view.frame.size.height)
    self.view.addSubview(chart)

    let model = AAChartModel.init()
        .chartType(AAChartType.Column)//Can be any of the chart types listed under `AAChartType`.
        .animationType(AAChartAnimationType.Bounce)
        .title("TITLE")//The chart title
        .subtitle("subtitle")//The chart subtitle
        .dataLabelEnabled(false) //Enable or disable the data labels. Defaults to false
        .tooltipValueSuffix("USD")//the value suffix of the chart tooltip
        .categories(["Jan", "Feb", "Mar", "Apr", "May", "Jun",
                     "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"])
        .colorsTheme(["#fe117c","#ffc069","#06caf4","#7dffc0"])
        .series([
            AASeriesElement()
                .name("Tokyo")
                .data([7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6])
                .toDic()!,
            AASeriesElement()
                .name("New York")
                .data([0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5])
                .toDic()!,
            AASeriesElement()
                .name("Berlin")
                .data([0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0])
                .toDic()!,
            AASeriesElement()
                .name("London")
                .data([3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8])
                .toDic()!,])
    chart.aa_drawChartWithChartModel(model)

Answer 1

我通过以下方式解决了该问题：

“构建阶段”>“复制捆绑包资源”菜单，单击+
点击“添加其他...”
导航到您的Pods文件夹，然后选择捆绑文件，在我的情况下为AAJSFile.bundle

这会将项目中的引用添加到包中，以便下次在您的命名空间中正确找到它。

Answer 2

此行

let path = Bundle.main.path(forResource: "AAChartView", ofType: "html", inDirectory: "AAJSFiles.bundle"

从主捆绑包加载的扩展而不是您所需的Pod捆绑包

let podBundle = Bundle(identifier:"hereSet")!
let path = podBundle.path(forResource: "AAChartView", ofType: "html", inDirectory: "AAJSFiles.bundle")

//

无法从Pod库加载资源
