我有一个奇怪的问题,如果我制作的可调整大小的图像(自定义视图)不在 NavigationButton 中,那么它可以正常工作,但如果它在其中,那么图像的大小仍然很好,但它变成了全蓝色。有谁知道出了什么问题?
struct DynamicallyResizableImage: View {
let imageName: String
let height: CGFloat
let width: CGFloat
init(imageName: String, height: CGFloat? = nil, width: CGFloat? = nil) {
self.imageName = imageName
let imageSize = UIImage(named: imageName)!.size
guard let height = height else {
if let width = width {
self.width = width
self.height = imageSize.height * (width/imageSize.width)
return
}
self.height = 0
self.width = 0
return
}
if let width = width {
self.height = height
self.width = width
return
}
self.height = height
self.width = imageSize.width * (height/imageSize.height)
}
var body: some View {
Image(imageName)
.resizable()
.frame(width: width, height: height)
}
}
NavigationButton(destination: PicturePreviewView(imageName: "IMG_4955")) {
DynamicallyResizableImage(imageName: "IMG_4955", height: 200)
}
当未嵌入 NavigationButton 时,一切正常。当嵌入 NavigationButton 时,图像会被蓝色填充。
任何人都知道如何解决它?谢谢!!!
