SwiftUI 文本在 HStack 中超出屏幕

Question

除了 .lineLimit(nil), .fixedSize(horizontal: true, vertical: false), .fixedSize(horizontal: false, vertical: true) 我什么都试过了，我不知道怎么办如果文本超出屏幕范围，则将文本放在下一行。文本是按钮，按钮在列表中。

func showTime(hm: HourAndMinute) -> some View{
    
    return HStack {
        Text(String(hm.hour)).bold()
        ForEach(hm.minute, id: \.self) { minute in
            
            Button(action: {
                
                print(hm.minute)
                
            }) {
                Text(String(minute)).frame(width: 30, height: 25).background(Color("hour")).cornerRadius(5)
                
            }.buttonStyle(BorderlessButtonStyle())
            
        }
    }.fixedSize(horizontal: true, vertical: false)
}

Answer 1

如果你不想错过任何一个框，你可以尝试使用 ScrollView。

ScrollView(.horizontal) {
    HStack {
        Text(String(hm.hour)).bold()
        ForEach(hm.minute, id: \.self) { minute in                    
            Button(action: {
                print(hm.minute)                
            }) {
                Text(String(perc))
                   .frame(width: 30, height: 25)
                   .background(Color("ora")).cornerRadius(5)
            
            }.buttonStyle(BorderlessButtonStyle())            
        }
    }
}

另一方面，如果您想剪裁容器视图，您可以使用：

.clipShape(Rectangle())

我找到了答案：LazyVGrid

获取屏幕宽度：

let singleWidth:CGFloat = UIScreen.main.bounds.width

GridItemLayout:

var gridItemLayout = Array(repeating: GridItem(.fixed(30), spacing: 10), count: Int(singleWidth/50))

和return LazyVGrid (columns: gridItemLayout, spacing: 10) {

最终解：

let singleWidth:CGFloat = UIScreen.main.bounds.width

func showTime(hm: HourAndMinute) -> some View{
var gridItemLayout = Array(repeating: GridItem(.fixed(30), spacing: 10), count: Int(singleWidth/50))
        
        return  LazyVGrid (columns: gridItemLayout, spacing: 10) {
        Text(String(hm.hour)).bold()
        ForEach(hm.minute, id: \.self) { minute in
            
            Button(action: {
                
                print(hm.minute)
                
            }) {
                Text(String(minute)).frame(width: 30, height: 25).background(Color("hour")).cornerRadius(5)
                
            }.buttonStyle(BorderlessButtonStyle())
            
        }
    }
}
