在UIScrollView中获取CATiledLayer支持的视图的图像快照

// 获取 CATiledLayer 列表
let tiledLayers = scrollView.subviews.compactMap { $0 as? CATiledLayer }

// 遍历 CATiledLayer 实例
tiledLayers.forEach { tiledLayer in
    // 获取当前 CATiledLayer 支持的视图快照
    let snapshot = CGRect(x: 0, y: 0, width: tiledLayer.bounds.width, height: tiledLayer.bounds.height)
    let image = UIGraphicsImageRenderer(size: snapshot.size).image { _ in
        tiledLayer.render(in: snapshot)
    }
    
    // 保存图像快照到本地或云端
    saveImage(image: image, url: URL(fileURLWithPath: "/Users/user/Library/Developer/Xcode/DerivedData/Build/Intermediates.noindex/XCBuildData/project.build/Debug-iphonesimulator/project.build/image_snapshots.png"))
