SwiftUI无法调整图像大小

Question

我正在尝试在SwiftUI中创建图像，并且面临的问题是，即使设置了内容模式填充，图像也无法调整自身大小

struct LoginView: View {
    var body: some View {
        Image("app-icon")
                .frame(width: percent(80, ofSize: "width"), height: percent(40, ofSize: "width"), alignment: Alignment.center)
                .aspectRatio(contentMode: ContentMode.fill)
                .scaledToFill()
                .clipped()

    }
}

然后我尝试了

struct LoginView: View {
    var body: some View {
        Image("app-icon")
                .frame(width: percent(80, ofSize: "width"), height: percent(40, ofSize: "width"), alignment: Alignment.center)
                .aspectRatio(contentMode: ContentMode.fit)
                .scaledToFit()
                .clipped()

    }
}

两个代码都具有相同的效果，图像大小不变

Answer 1

• 在代码中添加.resizable()修饰符

  Image("app-icon")
     .resizable()
     .scaledToFill()
     .frame(width: percent(80, ofSize: "width"), height: percent(40, ofSize: "width"), alignment: Alignment.center)
     .clipped()
  

Answer 2

必须添加.resizable()作为Image之后的第一个修改器，其他修改器才能生效。
