SwiftUI 不使用自动布局,如何为所有设备创建唯一尺寸的界面?

SwiftUI doesn't use auto layout, how to create a unique size interface for all devices?

我以前不使用 SwiftUI 并尝试创建中型小部件,但我无法从另一个程序(YouTube 音乐中型小部件)重新创建此小部件的副本,我在不同屏幕上的第四个单元格具有不同的边缘边距,我不知道如何解决这个边距,因为 SwiftUI 没有自动布局。我把我的小部件代码贴在下面,如果有人知道我做错了什么,请指正。

我的Widget截图和我想要的widget:

我的插件代码:

struct Provider: IntentTimelineProvider {
    func placeholder(in context: Context) -> SimpleEntry {...}

    func getSnapshot(for configuration: ConfigurationIntent, in context: Context, completion: @escaping (SimpleEntry) -> ()) {...}

    func getTimeline(for configuration: ConfigurationIntent, in context: Context, completion: @escaping (Timeline<Entry>) -> ()) {...}
}

struct SimpleEntry: TimelineEntry {...}

SwiftUI 为您自动布局,它与 UIKit 不同,您应该同时支持所有屏幕,这就是为什么间距会改变但您可以设置“规则”

//Prevents the repeating of code
struct ImageView: View {
    var deeplinkURLFirst: URL
    let mainColor: Color
    //Add another parameter for the image info I counldn't reprodice that
    var body: some View {
        Link(destination: deeplinkURLFirst) {
            ZStack {
                RoundedRectangle(cornerRadius: 10)
                    .foregroundColor(mainColor)
                    .overlay(
                    //Keep image within rectangle bounds
                    //The systemName stuff is just to replicate an actual image fill in with your image code
                    Image(systemName: "square")
                    .resizable())
            }
        }
        //Rule
        //Keep the images squares or you can set frame using your iconSize 
        //for all but the size of an iPhone 7 or SE is not the same 
        //as a ProMax it is best to set a ratio
        //If you fix the size padding will have to give way to adjust for larger/smaller screens.
        .aspectRatio(1, contentMode: .fit)
