问题描述
我有一个选择器,在成功选择视频后,我无法获得资产的路径.所以我有这个:
I am having a picker, and after successfully picking of video, I can't get a path to the asset. So I have this:
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
if let videoURL = info[UIImagePickerController.InfoKey.mediaURL] as? URL {
MediaManager.shared.sourceType = picker.sourceType
self.metadata.videoURL = videoURL
}
}
一般在用手机保存的视频,甚至很多通过 iTunes 或不同工具上传的视频中,我总能找到路径.
Generally in videos saved with the phone, or even many videos uploaded through iTunes or with different tools, I always get a path.
在这种情况下,我使用 AirDrop 传输了 400mb 的高分辨率视频 (720p),当我选择它时,它的路径为零......我在这里遗漏了什么吗?
In this case, I transferred a hiRes video (720p) of 400mb, using AirDrop, and when I pick it, I get nil for its path...Am I missing something here?
我猜不是因为它的传输方式,因为我收到了相同问题的报告,使用另一个应用程序将其传输到手机.
I guess it is not because of the way it is transferred, cause I got a report for the same issue, using another app to transfer it to the phone.
推荐答案
对于所有可能的情况,您都需要这样处理
You need to handle it like this for all possible cases
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any] {
picker.dismiss(animated: true)
print("info[UIImagePickerController.InfoKey.mediaURL] referenceURL " , info[.referenceURL] )
print("info[UIImagePickerController.InfoKey.mediaURL] phAsset " , info[.phAsset])
print("info[UIImagePickerController.InfoKey.mediaURL] mediaURL " , info[.mediaURL])
if let asset = info[UIImagePickerController.InfoKey.phAsset] as? PHAsset {
asset.getURL { (tempPath) in
DispatchQueue.main.async {
}
}
}
else if let media = info[UIImagePickerController.InfoKey.mediaURL] as? URL {
}
else
if let ref = info[UIImagePickerController.InfoKey.referenceURL] as? URL {
let res = PHAsset.fetchAssets(withALAssetURLs: [ref], options: nil)
res.firstObject!.getURL { (tempPath) in
DispatchQueue.main.async {
}
}
}
}
