Save PDF file to iBooks was working fine until upgrade to xCode7. Now getting an error:
Downcast from String? to String only unwraps optionals... for this line:
let documentsDirPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true).first as? String
Not sure how to fix that. Tried:
let documentsDirPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as String
But got new error. Any help would be appreciated.
Try this:
let documentsDirPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true).first as String!

I am uploading image and video to QuickBlox. My upload is successful but when i download the following scenarios occour:
1) In case of image i am able to download image and show (No issues in this)
2) My question is about video with below points
a) I am able upload video successfully
b) How would i be able to recognize the extension of video from server? I need sample code for uploading and downloading video from the QuickBlox. As if i upload .mov file then what should be the filetype and what should be in case of .mp4 and so on. And when i download the file how would i know the correct extension for the file and then how to get the correct file from the server and save it.
When uploading a video, set the type to "video" in the attachment and the corresponding content type, for example "video/mp4":
QBRequest.uploadFile(with: localVideoUrl, fileName: nameVideo, contentType: "video/mp4", isPublic: true,
successBlock: { (response: QBResponse, uploadedBlob: QBCBlob) -> Void in
let attachment = QBChatAttachment()
attachment.id = uploadedBlob.uid
attachment.name = uploadedBlob.name
attachment.type = "video"
attachment["size"] = "\(uploadedBlob.size)"
// send message with attachment
}, statusBlock: { (request : QBRequest?, status : QBRequestStatus?) -> Void in
let progress = CGFloat(Float(status.percentOfCompletion))
// show progress
}
}) { (response : QBResponse) -> Void in
//error handler
}
When you receive a message with attachment and attachment type is "video”, refer to this example:
let attachment = message.attachments?.first
if attachment.type == "video" {
QBRequest.downloadFile(withUID: attachment.id, successBlock: { (response: QBResponse, fileData: Data) in
let fileData = fileData as NSData
let fileName = ID + "_" + attachment.name
let filePath = NSTemporaryDirectory() + fileName
let fileURL = URL(fileURLWithPath: filePath)
if fileData.write(to: fileURL, atomically: true) == true {
//do what you need with the video - cache, save, play, etc.
} else {
print("failure write")
}
}, statusBlock: { (request: QBRequest, status: QBRequestStatus?) in
let progress = CGFloat(status.percentOfCompletion)
//show progress
}, errorBlock: { (response: QBResponse) in
//error handler
})
}
I'm currently developing an application in swift 3 for a school project that requires uploading files to google drive .
The upload is currently working , but i need to inform users with an upload bar.
Here the current code
let folderId: String = folders[indexPath.row].folderId
let metadata = GTLRDrive_File.init()
metadata.name = "Ruin.mp3"
// metadata.mimeType = "application/vnd.google-apps.photo"
metadata.parents = [folderId]
guard let filePath = Bundle.main.path(forResource: "Ruin", ofType: "mp3") else {
return
}
guard let fileData = FileManager.default.contents(atPath: filePath) else {
return
}
let uploadParameters = GTLRUploadParameters(data: fileData , mimeType: "audio/mpeg")
uploadParameters.shouldUploadWithSingleRequest = true
let query = GTLRDriveQuery_FilesCreate.query(withObject: metadata, uploadParameters: uploadParameters)
query.fields = "id"
self.service.executeQuery(query, completionHandler: {(ticket:GTLRServiceTicket, object:Any?, error:Error?) in
if error == nil {
// print("File ID \(files.identifier)")
}
else {
print("An error occurred: \(error)")
}
})
Thanx in advance
I am getting some issues related to APNG file, APNG file animation working perfect if i put APNG files in resource bundle , But when i have download same APNG file from assets server and saving APNG file into resource directory and then load using MSSticker like this way. after loading it showing only first frame.if anyone wanna try to check APNG file please have a look to this.
let imagePath = Bundle.main.path(forResource: imgName, ofType: ".png")
let pathurl = URL(fileURLWithPath: imagePath!)
do {
try cell.stickerview.sticker = MSSticker(contentsOfFileURL: pathurl, localizedDescription: "anything that you want")
}
catch {
fatalError("Failed to create sticker: \(error)")
}
Here i am saving image & getting saved image url from resource directory:
static func saveImage(image: UIImage , name:String) -> Bool? {
guard let data = UIImagePNGRepresentation(image) else {
return false
}
guard let directory = try? FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: false) as NSURL else {
return false
}
do {
try data.write(to: directory.appendingPathComponent(name)!)
return true
} catch {
print(error.localizedDescription)
return false
}
}
static func getSavedImageUrl(named: String) -> URL? {
if let dir = try? FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: false) {
return URL(fileURLWithPath: dir.absoluteString).appendingPathComponent(named)
}
return nil
}
I have written the extension in custom MSSticker class
extension MSStickerView {
func downloadedFrom(url: URL , name: String) {
URLSession.shared.dataTask(with: url) { (data, response, error) in
guard let httpURLResponse = response as? HTTPURLResponse, httpURLResponse.statusCode == 200,
let mimeType = response?.mimeType, mimeType.hasPrefix("image"),
let data = data, error == nil,
let image = UIImage(data: data)
else { return }
DispatchQueue.main.async() { () -> Void in
// self.sticker = image
_ = GameUtil.saveImage(image: image, name: name)
if let pathurl = GameUtil.getSavedImageUrl(named: name) {
do {
try self.sticker = MSSticker(contentsOfFileURL: pathurl, localizedDescription: "Raid")
}
catch {
fatalError("Failed to create sticker: \(error)")
}
}
self.startAnimating()
}
}.resume()
}
func downloadedFrom(link: String , name: String) {
guard let url = URL(string: link) else { return }
downloadedFrom(url: url ,name: name)
}
I think problem is this UIImagePNGRepresentation. Why convert Data to UIImage and then use UIImagePNGRepresentation.
Try saving data directly.
static func saveData(data: Data , name:String) -> Bool? {
guard let directory = try? FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: false) as NSURL else {
return false
}
do {
try data.write(to: directory.appendingPathComponent(name)!)
return true
} catch {
print(error.localizedDescription)
return false
}
}
And ignore image just pass data.
_ = GameUtil.saveImage(data: data, name: name)
I have to display a title of the song which I was selected I get the title(No need to play the song in the music library).What my question is I want to send song I was selected(Encoded) to PHP server..To display the song in a table view from the server and play the song...I want to find the correct path for iTunes music library so that I can encode easily.

Due to copyright protection you can only play songs from music library. You can't access row audio file!.I guess
Sorry for my English I'll do my best.
I have an issue trying to upload photos from the user's library.
First, I get user's photo with this method
func grabPhotos(){
let imgManager = PHImageManager.defaultManager()
let requestOptions = PHImageRequestOptions()
requestOptions.synchronous = false
requestOptions.deliveryMode = .FastFormat
let fetchOptions = PHFetchOptions()
fetchOptions.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: false)]
if let fetchResult : PHFetchResult = PHAsset.fetchAssetsWithMediaType(.Image, options: fetchOptions){
if fetchResult.count > 0{
for i in 0..<fetchResult.count{
let asset = fetchResult.objectAtIndex(i) as! PHAsset
if NSComparisonResult.OrderedSame == asset.creationDate!.compare(self.appDelegate.dateLastUpload!){
print("meme date")
}
else if NSComparisonResult.OrderedAscending == asset.creationDate!.compare(self.appDelegate.dateLastUpload!){
}
else {
imgManager.requestImageDataForAsset(asset, options: requestOptions, resultHandler: { (data, string, orientation, objects) in
self.Upload((UIImage(data: data!)?.CGImage)! , nomImage: "\(asset.creationDate)" )
})
}
}
}
else{
print("you got no photos")
}
}
}
as you can see, each time I get a photo I want to upload it to my server.
the upload part works well.
Here is the upload method
func clickUpload(image:CGImage,nomImage : String){
let url = NSURL(string: "http://192.168.1.20:1993/upload")
let image_photo = UIImage(CGImage: image)
let request = NSMutableURLRequest(URL: url!)
request.HTTPMethod = "POST"
let boundary = generateBoundaryString()
//define the multipart request type
request.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type")
if var image_data = UIImageJPEGRepresentation(image_photo,0.8){
let body = NSMutableData()
let fname = nomImage
let mimetype = "image/jpg"
//define the data post parameter
body.appendData("--\(boundary)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData("Content-Disposition:multipart/form-data; name=\"test\"\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData("enctype=\"multipart/form-data".dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData("hi\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData("--\(boundary)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData("Content-Disposition:form-data; name=\"file\"; filename=\"\(fname)\"\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData("Content-Type: \(mimetype)\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData(image_data)
body.appendData("\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData("--\(boundary)--\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
//request.setValue("multipart/form-data", forHTTPHeaderField: "content-Type")
request.HTTPBody = body
let session = NSURLSession.sharedSession()
let task = session.dataTaskWithRequest(request) {
(
let data, let response, let error) in
guard let _:NSData = data, let _:NSURLResponse = response where error == nil else {
print("error")
return
}
let dataString = NSString(data: data!, encoding: NSUTF8StringEncoding)
print(dataString)
}
task.resume()
}
else {
print(« data nil")
}
}
Now problems come... It works well if I upload photos with reduced size, but I want to upload them in HighQualityFormat.
I got 170 photos on my device, and it uploads approximatively 80 photos before crashing with this message
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'NSAllocateMemoryPages(1504802) failed'
Could you guys help me to solve it or give me another way to achieve this?
Thank you all.
