我面临一个非常奇怪的问题。我试图选择一个图像,并在裁剪后将其上传到服务器。我无法在ios 11.0.3上运行的iphone 5上执行此操作。但在运行ios 10.3.3的iphone 5上运行正常。
我使用以下代码从图库中选择图片:
func showImgPicker()
{
self.imagePicker.allowsEditing = false
self.imagePicker.sourceType = .photoLibrary
self.present(self.imagePicker, animated: true, completion: nil)
}
@IBAction func getImgs(_ sender: UIButton) {
let photos = PHPhotoLibrary.authorizationStatus()
if photos == .notDetermined {
PHPhotoLibrary.requestAuthorization({status in
if status == .authorized{
self.showImgPicker()
} else {
}
})
}
else
{
showImgPicker()
}
}
@objc func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
let imageURL = info[UIImagePickerControllerReferenceURL] as! NSURL
picker.dismiss(animated: true, completion: nil)
dismiss(animated: true) {
self.delegate?.presentEditor(img: (info[UIImagePickerControllerOriginalImage] as? UIImage)!, id: self.id!, type: self.commentType)
}
}
一旦图像被挑选出来,我就会发送它进行封送,发布图片保存在应用的本地文档目录中:
static func SaveImgLocal(img: UIImage, tsStr: String) -> String
{
let fileManager = FileManager.default
do {
let documentDirectory = try fileManager.url(for: .documentDirectory, in: .userDomainMask, appropriateFor:nil, create:false)
let fileURL = documentDirectory.appendingPathComponent("\(tsStr).jpeg")
if let imageData = UIImageJPEGRepresentation(img, 1) {
try imageData.write(to: fileURL)
return "\(tsStr).jpeg"
}
else
{
return Constants.MESSAGE_ERROR
}
} catch {
return Constants.MESSAGE_ERROR + " " + error.localizedDescription
}
}
最后我将图像上传到服务器:
let url2 = URL(string: "file:///private\((url?.absoluteString)!)")
print(url2)
print(url)
let salesObj = try SalesFactory.getSalesService()
try uploadDoc(url: Urls.uploadImgUrl, docUrl: url2!, parseResponse: { (result) in
print(result)
}
public static func uploadDoc(url: String, docurl: URL, httpResponse: @escaping (DataResponse<Any>) -> Void) throws
{
let hdr: HTTPHeaders = ["Accept": "application/json"]
Alamofire.upload(docurl, to: url, method: .post, headers: hdr).responseJSON { (response) in
print(response)
httpResponse(response)
}
}
相同的代码适用于ios 10.3.3,但不适用于ios 11.0.3。没有错误。服务器发送提示上传失败的消息。
答案 0 :(得分:0)
在info.plist中添加了NSPhotoLibraryAddUsageDescription并压缩了图像。它开始工作了。
如果遇到此问题,请在info.plist中添加NSPhotoLibraryUsageDescription和NSPhotoLibraryAddUsageDescription。
