I have this code here, that is incomplete. The First part downloads a file from a URL:
NSString *stringURL = #"http://www.example.com/pdf/035.pdf";
NSURL *url = [NSURL URLWithString:stringURL];
NSData *urlData = [NSData dataWithContentsOfURL:url];
if ( urlData )
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [NSString stringWithFormat:#"%#/%#", documentsDirectory,#"035.pdf"];
[urlData writeToFile:filePath atomically:YES];
}
and puts it in: var/mobile/Containers/Data/Application/
Now I want to use this download file with Document Interaction Controller like so:
NSURL *URL = [[NSBundle mainBundle] URLForResource:#"035" withExtension:#"pdf"];
if (URL) {
// Initialize Document Interaction Controller
self.documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:URL];
// Configure Document Interaction Controller
[self.documentInteractionController setDelegate:self];
// Preview PDF
[self.documentInteractionController presentPreviewAnimated:YES];
}
How would I get the file from var/mobile/Containers/Data/Application/ and display it using Document Interaction Controller ?

But Want the pdf file do not store in documentsDirectory.Need to add one button click user click the button, then Binary to pdf convert will happened and display in web view. here my code. How is possible help me. thanks advance.
NSString *binaryString =#"Binary code to change";
myData = [NSData dataFromBase64String: binaryString];
[self savePDF:myData];
- (void)savePDF:(NSData *)pdfContent
{
NSArray *paths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory, NSUserDomainMask ,YES );
NSString *documentsDirectory = [paths objectAtIndex:0];
finalPath = [documentsDirectory stringByAppendingPathComponent:#"myPdf.pdf"];
NSLog(#"%#",finalPath);

If you don't want to store pdf file to DocumentsDirectory then
try following, hope it will work for you
NSString *binaryString =#"Binary code to change";
myData = [NSData dataFromBase64String: binaryString];
[self savePDF:myData];
- (void)savePDF:(NSData *)pdfContent
{
NSArray *paths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory, NSUserDomainMask ,YES );
NSString *documentsDirectory = [paths objectAtIndex:0];
finalPath = [documentsDirectory stringByAppendingPathComponent:#"myPdf.pdf"];
NSLog(#"%#",finalPath);
NSURL *url = [NSURL fileURLWithPath:finalPath];
//[pdfContent writeToURL:url atomically:YES];
[aWebView loadRequest:[NSURLRequest requestWithURL:url]];
}
Comment //[pdfContent writeToURL:url atomically:YES]; line
and check
How can I check if a file is download and save on device? Help me please.
- (void) song{
if (_index1 == 0) {
NSString *stringURL = #"https://drive.google.com/uc?export=download&id=0B0EJbcHq3ZALWUo0a05LMWNzeDg";
NSURL *url = [NSURL URLWithString:stringURL];
NSData *urlData = [NSData dataWithContentsOfURL:url];
if ( urlData )
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [NSString stringWithFormat:#"%#/%#", documentsDirectory,#"music.mp3"];
[urlData writeToFile:filePath atomically:YES];
self.audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL URLWithString:filePath] error:nil];
}
}
}
If you want to see if the file music.mp3 is in your Documents folder:
NSString *filePath = [documentsDirectory stringByAppendingPathComponent#"music.mp3"];
BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:filePath];
This only makes sense if that file is always the same file. If it can be different files then you need to associate the URL you use to download with the file you stored it in.
I tried till downloading but downloaded video is showing not supported plz help thanks for help.

You do realize that your URL doesn't actually point to a "video" file?
.m3u8 Files are not actual Asset files, rather, they are more akin to a playlist. They are used in HTTP Live Streaming and provide a location for "Segments" based on available bandwidth

Here is my code.I have more 10 pdf and want to store them locally on device and display next time without download.
It saves the pdf again and i cannot check whether it is downloaded or not ?
Please help me
I am not sure what you mean but, to download a file , you need to use NSData:
NSString *stringURL = #"your file URL";
NSURL *url = [NSURL URLWithString:stringURL];
NSData *urlData = [NSData dataWithContentsOfURL:url];
if ( urlData )
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [NSString stringWithFormat:#"%#/%#", documentsDirectory,#"filename.extension"];
[urlData writeToFile:filePath atomically:YES];
}
Now the downloaded file exists at filePath and you can get it by using:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:#"filename with extension"];
NSString *content = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:NULL];
you can try this to check if file exists at file path:
NSString* documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString* file = [documentsPath stringByAppendingPathComponent:#"filename"];
BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:file];
if(fileExists){
//dont download, just grab it and display it
}
else{
//download and display it
}
