Question

I am currently using SwiftUI s Picker API, and would like to increase the Picker row s height. The reason for this is when text has a bigger font, the items overlap.
I am trying to avoid using UIPickerView + UIViewRepresentable if possible & would like to achieve this using purely SwiftUI if possible.

我尝试使用<条码>航天器、<条码> pa>/条码>和<条码>(>>>>>,但截至目前为止未加列。

我知道这一特征已经在监控系统上提供,但是在进入现场时是否有任何替代办法?

我附上了上述问题的基本皮条。提前感谢。

struct ContentView: View {
    @State private var selectedNum = 0

    var body: some View {
        Picker("", selection: self.$selectedNum) {
            Text("1").font(.system(size: 80))
            Text("2").font(.system(size: 80))
            Text("3").font(.system(size: 80))
            Text("4").font(.system(size: 80))
            Text("5").font(.system(size: 80))
            Text("6").font(.system(size: 80))
        }
        .pickerStyle(.wheel)
    }
}

这是法典的结果。

您应使用该守则:

func pickerView(_ pickerView: UIPickerView, rowHeightForComponent component: Int) -> CGFloat {
    return 80
}
