在范围内找不到类型“IAxisValueFormatter”

Question

我正在尝试使用库https://github.com/danielgindi/Charts但最近它在这部分给我带来了问题：

final class CustomDateFormatter: NSObject, IAxisValueFormatter {

private let dateFormatter = DateFormatter()

override init() {
super.init()
dateFormatter.dateFormat = "MMM-yy"
}

func stringForValue(_ value: Double, axis: AxisBase?) -> String {
let newDate = Calendar.current.date(byAdding: .month, value: Int(value), to: Date())
return dateFormatter.string(from: newDate ?? Date()).lowercased()
}

}

错误是：

Cannot find type 'IAxisValueFormatter' in scope

Answer 1

貌似IAxisValueFormatter改名了AxisValueFormatter。更多信息请参见https://github.com/danielgindi/Charts/issues/4775
