ios - 无法在 ios 11.0.3 中上传图片
<p><p>我正面临一个非常奇怪的问题。我正在尝试选择图像并在裁剪后将其上传到服务器。我无法在运行 ios 11.0.3 的 iphone 5s 上执行此操作。但同样适用于运行 ios 10.3.3 的 iphone 5。 </p>
<p>我正在使用以下代码从图库中选择图片:</p>
<pre><code> 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: ) {
let imageURL = info as! NSURL
picker.dismiss(animated: true, completion: nil)
dismiss(animated: true) {
self.delegate?.presentEditor(img: (info as? UIImage)!, id: self.id!, type: self.commentType)
}
}
</code></pre>
<p>一旦图像被选中，我将其发送以进行复制，并发布图像正在保存在应用程序的本地文档目录中:</p>
<pre><code> 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
}
}
</code></pre>
<p>最后我将图像上传到服务器:</p>
<pre><code>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)
}
}
</code></pre>
<p>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。服务器发送一条消息，提到上传失败。</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>在 info.plist 中添加 NSPhotoLibraryAddUsageDescription 并压缩图像。它开始工作了。 </p>
<p>任何遇到此问题的人，请在 info.plist 中添加 NSPhotoLibraryUsageDescription 和 NSPhotoLibraryAddUsageDescription。</p></p>
