我正在尝试保存使用视觉套件扫描的多张图像,但似乎只有第一张图像使用共享表保存。我该如何纠正这个问题。
扫描后保存图像
for i in 0...scan.pageCount-1 {
let originalImage = scan.imageOfPage(at: i)
let fixedImage = originalImage.jpegData(compressionQuality: 0.7)
let reloadedImage = UIImage(data: fixedImage!)
let imagetoshare = [reloadedImage!]
let activityViewController = UIActivityViewController(activityItems: imagetoshare, applicationActivities: nil)
if let popoverController = activityViewController.popoverPresentationController {
popoverController.sourceView = self.view
popoverController.sourceRect = CGRect(x: self.view.bounds.midX, y: self.view.bounds.midY, width: 0, height: 0)
popoverController.permittedArrowDirections = []
}
// exclude some activity types from the list (optional)
// present the view controller
self.present(activityViewController, animated: true, completion: nil)
}
由于 iPad 在调出共享表时出现问题,因此添加了 popover 控制器代码...

如果您想知道 reloadedImage 函数是什么:
func reloadedImage(_ originalImage: UIImage) -> UIImage {
guard let imageData = originalImage.jpegData(compressionQuality: 1),
let reloadedImage = UIImage(data: imageData) else {
return originalImage
}
return reloadedImage
}
编辑:我已经从 pageCount 中删除了“-1”,我收到了这个错误:
-[VNDocumentCameraScan imageOfPageAtIndex:]: index (2) beyond bounds (2).'
编辑2:
var imagetoShare = [UIImage]()
for i in 0...scan.pageCount-1 {
let originalImage = scan.imageOfPage(at: i)
let fixedImage = originalImage.jpegData(compressionQuality: 0.7)
let reloadedImage = UIImage(data: fixedImage!)
imagetoShare.append(reloadedImage!)
let activityViewController = UIActivityViewController(activityItems: imagetoShare, applicationActivities: nil)
if let popoverController = activityViewController.popoverPresentationController {
popoverController.sourceView = self.view
popoverController.sourceRect = CGRect(x: self.view.bounds.midX, y: self.view.bounds.midY, width: 0, height: 0)
popoverController.permittedArrowDirections = []
}
// exclude some activity types from the list (optional)
// present the view controller
self.present(activityViewController, animated: true, completion: nil)
我什至尝试过:
imagetoShare: [UIImage] = [UIImage]()
但仍然没有运气
在这些更改之后,我的调试器日志显示,
