添加帧中断 .clipShape() SwiftUI

Question

所以我将图像加载到名为 'RemoteImage' 的自定义结构中，该结构接收 URL 并将其加载到 SwiftUI Image() 中。出于某种原因，当我在 RemoteImage() 上使用 .clipShape() 时，它会将形状剪裁成圆形（虽然这是错误的 width/height，但是当我将 .frame() 设置为所需的 width/height，图像显示正确 width/height 但不再是圆形。不知道如何解决：

RemoteImage(url: image)
    .clipShape(Circle())
    .frame(width: 82, height: 82)

struct RemoteImage: View {
    private enum LoadState {
        case loading, success, failure
    }
    
    private class Loader: ObservableObject {
        var data = Data()
        var state = LoadState.loading
        
        init(url: String) {
            guard let parsedURL = URL(string: url) else {
                fatalError("Invalid URL: \(url)")
            }
            
            URLSession.shared.dataTask(with: parsedURL) { data, response, error in
                if let data = data, data.count > 0 {
                    self.data = data
                    self.state = .success
                } else {
                    self.state = .failure
                }
                
                DispatchQueue.main.async {
                    self.objectWillChange.send()
                }
            }.resume()
        }
    }
    
    @StateObject private var loader: Loader
    var loading: Image
    var failure: Image
    
    var body: some View {
        selectImage()
            .resizable()
    }
    
    init(url: String, loading: Image = Image(""), failure: Image = Image(systemName: "multiply.circle")) {
        _loader = StateObject(wrappedValue: Loader(url: url))
        self.loading = loading
        self.failure = failure
    }
    
    private func selectImage() -> Image {
        switch loader.state {
        case .loading:
            return loading
        case .failure:
            return failure
        default:
            if let image = UIImage(data: loader.data) {
                return Image(uiImage: image)
            } else {
                return failure
            }
        }
    }
}

工作正常，Xcode 13.3 / iOS 15.4，但是 clipShape 更适合在帧之后应用。

假设您只想要纵横比

var body: some View {
    selectImage()
        .resizable()
        .aspectRatio(contentMode: .fit)    // << here !!
}

添加帧中断 .clipShape() SwiftUI

Adding a frame breaks .clipShape() SwiftUI
