javascript - 尝试使用 highcharts 将数据点注入(inject) iOS webView

Question

在将 Android 应用程序移植到 iOS 时，我们遇到了障碍:我们有一个 UIwebView 设置来运行 HighCharts(它与他们提供的示例一起工作)，但我们无法弄清楚如何将变量传递给 Javascript 以显示实时变化。我们正在尝试做的 android-equivalent 是:

webView.loadUrl("javascript:" + "point = " + "[Date.UTC("
                    + mYear + "," + mMonth + "," + mDay + "," + hr
                    + "," + min + "," + sec + "),"
                    + value+ "];");

或者另一个例子:

webView.loadUrl("javascript:" + "var curve_name = " + "'Illuminance';" +
                    "var unit_of_meas = " + "'lx';" +
                    "var x_axis_title = " + "'Date';" +
                    "var y_axis_title = " + "'Illuminance (lx)';" +
                    "var plot_title = " + "'Illuminance data';" +
                    "var plot_subtitle = " + "'';")

Answer 1

UIWebView 有一个名为 stringByEvaluatingJavaScriptFromString 的方法，您可以使用它来运行脚本。我认为您也可以使用它来传递和初始化您喜欢的任何变量。
