Question

是否在采集器中有任何“pa”内容? 例如文本(......)。

Picker(selection: $picked) {
    ForEach(0...10, id: .self) { num in
        Text("(num)").tag("(num)")
            .font(.system(size: 30))
            .foregroundColor(pickedMinute == "(num)" ? .blue : .black)
            .padding(20) //  ***It does not work***
    }
} label: {
    Text("picker")
}

Answer 1

does work is the .font modifier. 并且还有<代码>。结合使用,你可以有更大的体,有更大的间隔:

Picker(selection: $picked) {
    ForEach(0...10, id: .self) { num in
        Text("(num)").tag("(num)")
            .font(.system(size: 15))
            .foregroundColor(pickedMinute == "(num)" ? .blue : .black)
    }
} label: {
    Text("picker")
}
.pickerStyle(.wheel)
.scaleEffect(2)

Picker in SwiftUI does not support padding, you can create a custom Picker with padding like the following:

ScrollView(.horizontal, showsIndicators: false) {
    HStack {
        ForEach(numbers, id: .self) { number in
            Text("(number)")
                .font(.system(size: 30))
                .foregroundColor(self.pickedNumber == number ? .blue : .black)
                .padding(20)
                .onTapGesture {
                    self.pickedNumber = number
                }
        }
    }
}
