[英]How to make CareKitUI Bar Charts compatible with SwiftUI
Currently, there is limited support for CareKit using SwiftUI.目前,有限的支持CareKit使用SwiftUI。
I understand, generally, the idea of making an object conforming to UIViewRepresentable
, but am struggling to get going with how this would work in practice.一般来说,我理解使对象符合
UIViewRepresentable
,但我正在努力了解这在实践中的工作方式。
The following is example code from the readme :以下是自述文件中的示例代码:
let chartView = OCKCartesianChartView(type: .bar)
chartView.headerView.titleLabel.text = "Doxylamine"
chartView.graphView.dataSeries = [
OCKDataSeries(values: [0, 1, 1, 2, 3, 3, 2], title: "Doxylamine")
]
So the init(type)
, headerView.titleLabel
and graphView.dataSeries
would need to be set as @Binding
variables in a struct conforming to UIViewRepresentable
, but I'm struggling to figure out how I have to use the following two functions:因此
init(type)
、 headerView.titleLabel
和graphView.dataSeries
需要在符合UIViewRepresentable
的结构中设置为@Binding
变量,但我正在努力弄清楚我必须如何使用以下两个函数:
func makeUIView() {}
func updateUIView() {}
Any help would be much appreciated.任何帮助将非常感激。
Actually only data requires binding, because type is part of initialization and title is hardly possible to be changed, so here is possible variant实际上只有数据需要绑定,因为类型是初始化的一部分,标题几乎不可能改变,所以这里有可能的变体
struct CartesianChartView: UIViewRepresentable {
var title: String
var type: OCKCartesianGraphView.PlotType = .bar
@Binding var data: [OCKDataSeries]
func makeUIView(context: Context) -> OCKCartesianChartView {
let chartView = OCKCartesianChartView(type: type)
chartView.headerView.titleLabel.text = title
chartView.graphView.dataSeries = data
return chartView
}
func updateUIView(_ uiView: OCKCartesianChartView, context: Context) {
// will be called when bound data changed, so update internal
// graph here when external dataset changed
uiView.graphView.dataSeries = data
}
}
