ios - 如何通过在SwiftUI中触摸屏幕的任何位置来更改文本

Question

大家好，我想通过触摸任意位置来随机更改文本，但是我只能通过触摸文本来更改文本。

var myArray = ["1", "2", "3"]

@State private var selectedSuggestion = Int.random(in: 0...2)

var body: some View {
    
    Text(myArray[selectedSuggestion])
        .frame(width: UIScreen.main.bounds.width * 1, height: UIScreen.main.bounds.height * 1)
        .font(.largeTitle)
        .multilineTextAlignment(.center)
        .onTapGesture {
            self.selectedSuggestion = Int.random(in: 0...2)
            
    }
}

解决方法是添加内容形状

Text(myArray[selectedSuggestion])
    .frame(width: UIScreen.main.bounds.width * 1, height: UIScreen.main.bounds.height * 1)
    .font(.largeTitle)
    .multilineTextAlignment(.center)
    .contentShape(Rectangle())              // << here !!
    .onTapGesture {
        self.selectedSuggestion = Int.random(in: 0...2)

}
