打印在控制檯。去的目標網址給你下載的文件的位置,打開你的終端,其拖放到終端刪除下載的圖像和終端會給你的實際path.Now比較兩者的路徑終端給你的那個和控制檯給你的那個,匹配那些。最喜歡他們是不同的,相應地改變他們。
示例代碼: -
上傳代碼: -
func profilePictureUploading(infoOnThePicture : [String : AnyObject],completionBlock : (()->Void)) {
if let referenceUrl = infoOnThePicture[UIImagePickerControllerReferenceURL] {
print(referenceUrl)
let assets = PHAsset.fetchAssetsWithALAssetURLs([referenceUrl as! NSURL], options: nil)
print(assets)
let asset = assets.firstObject
print(asset)
asset?.requestContentEditingInputWithOptions(nil, completionHandler: { (ContentEditingInput, infoOfThePicture) in
let imageFile = ContentEditingInput?.fullSizeImageURL
print("imagefile : \(imageFile)")
let filePath = FIRAuth.auth()!.currentUser!.uid + "/\(Int(NSDate.timeIntervalSinceReferenceDate() * 1000))/\(imageFile!.lastPathComponent!)"
print("filePath : \(filePath)")
FIRControllerClass.storageRef.child("ProfilePictures").child(filePath).putFile(imageFile!, metadata: nil, completion: { (metadata, error) in
if error != nil{
print("error in uploading image : \(error)")
}
else{
print("metadata in : \(metadata!)")
print(metadata?.downloadURL())
print("The pic has been uploaded")
print("download url : \(metadata?.downloadURL())")
self.uploadSuccess(metadata!, storagePath: filePath)
completionBlock()
}
})
})
}else{
print("No reference URL found!")
}
}
下載代碼: -
let paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
print("paths in user home page : \(paths)")
let documentDirectory = paths[0]
print("documents directory in homePage : \(documentDirectory)")
let filePath = "file:\(documentDirectory)/\(user!.uid).jpg"
var filePath2 : String = filePath
print(filePath)
let storagePath = NSUserDefaults.standardUserDefaults().objectForKey("storagePath") as! String
print("storagePath is : \(storagePath)")
storageRef.child("ProfilePictures").child(storagePath).writeToFile(NSURL.init(string: filePath)! , completion :
{ (url, err) -> Void in
if let error = err{
print("error while downloading your image :\(error)")
}else{
print("Download successful !")
print("the file filePath of the downloaded file : \(filePath)")
filePath2 = "\(documentDirectory)/\(self.user!.uid).jpg"
if let downloadedImage = UIImage(contentsOfFile: filePath2){
self.profilePictureImageView.image = downloadedImage
print("displayed")
}else{
print("unable to display")
}
}
})
其中storagePath是您存儲在NSUserDefaults的供以後參考的東西,如這一點,同時上傳您的圖片到您的Firebase存儲
我給你的codeBlocks只是衆多解決方案之一,有很多方法可以做到這一點,去https://firebase.google.com/docs/storage/ios/download-files
如果它解決了你的問題,請接受它作爲答案:) – Dravidian
