因此，由于人们对此有麻烦，因此开始了其他一些线程。像这个:Obtain NSURL from UIImagePickerController和这个:
Firebase storage upload works in Simulator but not on iPhone
我正在尝试遵循本教程:
https://firebase.google.com/docs/storage/ios/upload-files#upload_from_a_local_file
我的视频可以上传，但不能上传图像。
我的视频代码很简单:
if mediaType.isEqualToString(kUTTypeMovie as String) {
let videoURL = info[UIImagePickerControllerMediaURL] as? NSURL
fileToUploadURL = videoURL!
}
但是我的图片代码不起作用。这就是我最终得到的:
let imageUrl = info["UIImagePickerControllerReferenceURL"] as? NSURL
let assets = PHAsset.fetchAssetsWithALAssetURLs([imageUrl!], options: nil)
let asset = assets.firstObject
asset?.requestContentEditingInputWithOptions(nil, completionHandler: { (contentEditingInput, info) in
let imageFile = contentEditingInput?.fullSizeImageURL
// now call putFile with imageFile instead of imageUrl
self.fileToUploadURL = imageFile
})
似乎无论我做什么我都会出错。
这是我目前的错误

编辑:这是我的didFinishPickingMedia:
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
let mediaType = info[UIImagePickerControllerMediaType] as! NSString
print ("info: \(info)")
if mediaType.isEqualToString(kUTTypeImage as String) {
var newImage: UIImage
if let possibleImage = info["UIImagePickerControllerEditedImage"] as? UIImage {
newImage = possibleImage
}
else if let possibleImage = info["UIImagePickerControllerOriginalImage"] as? UIImage {
newImage = possibleImage
}
else {
return
}
/// CAN NOT GET NSURL working, NEED TO USE NSDATA
if let jpegData:NSData = UIImageJPEGRepresentation(newImage, 80) {
currentMediaTypeToUpload = "img"
fileToUploadDATA = jpegData
}
}
else if mediaType.isEqualToString(kUTTypeMovie as String) {
let videoURL = info[UIImagePickerControllerMediaURL] as? NSURL
fileToUploadURL = videoURL!
currentMediaTypeToUpload = "vid"
}
最佳答案
解决方案在这里:how do I get NSURL for an image froom UIImagePickerController? for upload to Firebase
应用于我们的问题:
if let referenceUrl = info[UIImagePickerControllerReferenceURL] {
////
let assetURL = NSURL(string: String(referenceUrl))
let assets = PHAsset.fetchAssetsWithALAssetURLs([assetURL!], options: nil)
let asset: PHAsset = assets.firstObject as! PHAsset
let manager = PHImageManager.defaultManager()
let requestSize = PHImageManagerMaximumSize
manager.requestImageForAsset(asset, targetSize: requestSize, contentMode: .AspectFit, options: nil, resultHandler: {(result, info)->Void in
// Result is a UIImage
// Either upload the UIImage directly or write it to a file
let imageData = UIImageJPEGRepresentation(result!, 0.8)
let imagePath = FIRAuth.auth()!.currentUser!.uid + "/\(Int(NSDate.timeIntervalSinceReferenceDate() * 1000)).jpg"
print ("filePath: ", imagePath)
let metadata = FIRStorageMetadata()
metadata.contentType = "image/jpeg"
self.storageRef.child(imagePath)
.putData(imageData!, metadata: metadata) { (metadata, error) in
if let error = error {
print("Error uploading: \(error.description)")
return
}
self.sendMessage([Constants.MessageFields.imageUrl: self.storageRef.child((metadata?.path)!).description])
print("Succeded")
}
})
}
使用此解决方案，我可以将文件上传到Firebase。
