I have coded a UIViewController that handles the upload (Only) for files to iCloud. So far it works well but I was trying to make it better with Network Changes using Reachability.
The way I handle the changes is:
lazy var searchQuery:NSMetadataQuery = {
let searchQueryTemp = NSMetadataQuery()
searchQueryTemp.searchScopes = [NSMetadataQueryUbiquitousDocumentsScope]
let searchPredicate = NSPredicate.init(format: "%K BEGINSWITH %@ && NOT %K.pathExtension = ''", argumentArray: [NSMetadataItemPathKey,trackFileManager.appICloudExportedMusic!.path,NSMetadataItemFSNameKey])
searchQueryTemp.predicate = searchPredicate
return searchQueryTemp
}()
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
print("\(logClassName): viewWillAppear")
appDelegate.appReachabilityDelegate = self
NotificationCenter.default.addObserver(self, selector: #selector(updateDataWithNotification), name: NSNotification.Name.NSMetadataQueryDidFinishGathering, object: searchQuery)
NotificationCenter.default.addObserver(self, selector: #selector(updateDataWithNotification), name: NSNotification.Name.NSMetadataQueryDidUpdate, object: searchQuery)
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
updateSearch()
}
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
print("\(logClassName): viewWillDisappear")
NotificationCenter.default.removeObserver(self)
}
@objc func updateDataWithNotification(notification: NSNotification){
print("\(logClassName): updateDataWithNotification \(searchQuery.results.count)")
if let queryObject = notification.object as? NSMetadataQuery{
if searchQuery == queryObject{
print("\(logClassName): Query count = \(queryObject.results.count)")
var iCloudAlbumArrayTemp = [FileIcloudAlbumHeader]()
/* Get the query results [URL] only files */
for result in queryObject.results{
/* Get Metadata for file */
if let metadataItem = result as? NSMetadataItem{
if let urlItem:URL = metadataItem.value(forKey: NSMetadataUbiquitousItemURLInLocalContainerKey) as? URL{
if var urlItemPath = urlItem.path.components(separatedBy: "Exported Music").last{
urlItemPath = String(urlItemPath.dropFirst())
let urlItemArray = urlItemPath.components(separatedBy: "/")
if urlItemArray.count == 3{
var albumICloudTrack = AlbumICloudTrack(url: urlItem)
let isUpdated:Bool = metadataItem.value(forKey: NSMetadataUbiquitousItemIsUploadedKey) as! Bool
let isUpdating: Bool = metadataItem.value(forKey: NSMetadataUbiquitousItemIsUploadingKey) as! Bool
let isDownloading:Bool = metadataItem.value(forKey: NSMetadataUbiquitousItemIsDownloadingKey) as! Bool
if isUpdated{
albumICloudTrack.status = .available
}
else{
if isUpdating{
let perInt = Int(metadataItem.value(forKey: NSMetadataUbiquitousItemPercentUploadedKey) as! Double)
print("\(logClassName): isUpdating: PerInt = \(perInt)")
let perDouble = metadataItem.value(forKey: NSMetadataUbiquitousItemPercentUploadedKey) as! Double
print("\(logClassName): isUpdating: PerInt = \(perDouble)")
albumICloudTrack.percentatge = Int(metadataItem.value(forKey: NSMetadataUbiquitousItemPercentUploadedKey) as! Double)
albumICloudTrack.status = .updating
}
else if isDownloading{
albumICloudTrack.status = .downloading
}
else{
albumICloudTrack.status = .notAvailable
}
}
/* Find Album */
var tempUrl = urlItem.deletingLastPathComponent()
let albumName = tempUrl.lastPathComponent
tempUrl = tempUrl.deletingLastPathComponent()
let artistName = tempUrl.lastPathComponent
//print("\(logClassName): Artist Name = \(artistName) && Album Name = \(albumName)")
let albumHeaderInex = findAlbumHeader(withArtistName: artistName, andAlbum: albumName, in: iCloudAlbumArrayTemp)
if albumHeaderInex != -1{
//print("\(logClassName): Appending Already exists")
iCloudAlbumArrayTemp[albumHeaderInex].urlTrackArray.append(albumICloudTrack)
}
else{
//print("\(logClassName): Creating New Header Album")
var albumHeader = FileIcloudAlbumHeader(artistName: artistName, albumName: albumName, url: urlItem.deletingLastPathComponent())
albumHeader.urlTrackArray.append(albumICloudTrack)
iCloudAlbumArrayTemp.append(albumHeader)
}
}
else{
print("\(logClassName): Discarting Item = \(urlItemPath)")
}
}
}
}
}
/* Copy content for updating Expanded status */
for iCloudAlbumIndex in iCloudAlbumArray.indices{
for iCloudAlbumTempIndex in iCloudAlbumArrayTemp.indices{
if iCloudAlbumArray[iCloudAlbumIndex].artistName == iCloudAlbumArrayTemp[iCloudAlbumTempIndex].artistName && iCloudAlbumArray[iCloudAlbumIndex].albumName == iCloudAlbumArrayTemp[iCloudAlbumTempIndex].albumName{
iCloudAlbumArrayTemp[iCloudAlbumTempIndex].isSelected = iCloudAlbumArray[iCloudAlbumIndex].isSelected
}
}
}
iCloudAlbumArray.removeAll()
for iCloudAlbumTempIndex in iCloudAlbumArrayTemp.indices{
iCloudAlbumArray.append(iCloudAlbumArrayTemp[iCloudAlbumTempIndex])
iCloudAlbumArray[iCloudAlbumTempIndex].urlTrackArray.sort {
return $0.trackName < $1.trackName
}
}
/* Reload table */
iCloudExportsTableView.reloadData()
}
}
}
The main problem here is that I see the file is updating in "Files" but
let isUpdating: Bool = metadataItem.value(forKey: NSMetadataUbiquitousItemIsUploadingKey) as! Bool
returns false
What am I not taking in consideration?
Thank you in advance
I have realised that despite NSMetadataUbiquitousItemIsUploadingKey returns false, NSMetadataUbiquitousItemPercentUploadedKey stills returns a number so:
let perDouble = metadataItem.value(forKey: NSMetadataUbiquitousItemPercentUploadedKey) as? Double ?? 100.00
if isUpdated{
albumICloudTrack.status = .available
}
else{
if isUpdating || perDouble < 100.00{
print("\(logClassName): isUpdating: perDouble = \(perDouble)")
albumICloudTrack.percentatge = Int(metadataItem.value(forKey: NSMetadataUbiquitousItemPercentUploadedKey) as! Double)
albumICloudTrack.status = .updating
}
Any other thoughts?
