I want to download one xml file that share in GitHub. This is my code but my result is site's xml. Where am I going wrong?
This is my code:
NSString *urlToDownload = #"https://github.com/qazaleh/xml-file/blob/master/result.xml";
NSURL *url = [NSURL URLWithString:urlToDownload];
NSData *urlData = [NSData dataWithContentsOfURL:url];
if ( urlData )
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [NSString stringWithFormat:#"%#/%#", documentsDirectory,#"result"];
NSLog(#"Downloading Started %#",filePath);
//saving is done on main thread
[urlData writeToFile:filePath atomically:YES];
}
}

I am getting responseObject like this
responseObject =
{
"img": "images/ProfileImage/defaultImg.jpg",
}
I have to store this image in app folder. Is there any way to do this.
The path is incomplete
You need to append base URL before "images/ProfileImage/defaultImg.jpg"
Then
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
NSString *urlToDownload = BaseURL + "images/ProfileImage/defaultImg.jpg";
NSURL *url = [NSURL URLWithString:urlToDownload];
NSData *urlData = [NSData dataWithContentsOfURL:url];
if (urlData)
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [NSString stringWithFormat:#"%#/%#", documentsDirectory,#"defaultImg.png"];
//saving is done on main thread
dispatch_async(dispatch_get_main_queue(), ^{
[urlData writeToFile:filePath atomically:YES];
NSLog(#"File Saved !");
});
}
});
Here is the code for downloading image and store into a local i.e "Document" directory in iOS app folder
In below code urlString is the url of image.
dispatch_queue_t downloadThumbNail = dispatch_queue_create("com.download.thumbnail", NULL);
dispatch_async(downloadThumbNail, ^
{
NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:urlString]];
UIImage *imageThumb = [UIImage imageWithData:imageData];
dispatch_async(dispatch_get_main_queue(),
^{
NSString *str = #“filename.png”;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsPath = [paths objectAtIndex:0];
NSString *filePath = [documentsPath stringByAppendingPathComponent:str];
NSData *pngData = UIImagePNGRepresentation(imageThumb);
[pngData writeToFile:filePath atomically:YES];
});
});
Enjoy codeing.
In this code, the audio is downloaded every time when I click on a button. I want to do check audio stored locally. If stored as run it without loading. How can I do this?
- (void) song{
NSString *stringURL = #"https://drive.google.com/uc?export=download&id=0B6zMam2kAK39VHZ1cUZsM3BhQXM";
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];
}
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [NSString stringWithFormat:#"%#/%#", documentsDirectory,#"music.mp3"];
self.audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL URLWithString:filePath] error:nil];
}
NSFileManager has the following methods:
- (BOOL)fileExistsAtPath:(NSString *)path;
- (BOOL)fileExistsAtPath:(NSString *)path isDirectory:(nullable BOOL *)isDirectory;
- (BOOL)isReadableFileAtPath:(NSString *)path;
- (BOOL)isWritableFileAtPath:(NSString *)path;
- (BOOL)isExecutableFileAtPath:(NSString *)path;
- (BOOL)isDeletableFileAtPath:(NSString *)path;
So we check like this:
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:#"music.mp3"];
BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:filePath isDirectory:NO];
if (!fileExists) {
// start the download process here then save
[urlData writeToFile:filePath atomically:YES];
}
How can I check if a file is download and save on device? Help me please.

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.
Here is my code:
Downloading video from url code
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
NSLog(#"Downloading Started");
NSString *urlToDownload = #"http://cdn-fms.rbs.com.br/vod/hls_sample1_manifest.m3u8";
NSURL *url = [NSURL URLWithString:urlToDownload];
NSData *urlData = [NSData dataWithContentsOfURL:url];
if ( urlData )
{
NSLog(#"urldata %# ",urlData);
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [NSString stringWithFormat:#"%#/%#", documentsDirectory,#"thefifle2.mov"];
//saving is done on main thread
dispatch_async(dispatch_get_main_queue(), ^{
[urlData writeToFile:filePath atomically:YES];
NSLog(#"File Saved !%#",filePath);
_url = [NSURL URLWithString:filePath];
[self playv];
});
}
});
Play downloaded video using MPMoviepLayercontroller
NSURL *vedioURL;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSArray *filePathsArray = [[NSFileManager defaultManager] subpathsOfDirectoryAtPath:documentsDirectory error:nil];
NSLog(#"files array %#", filePathsArray);
NSString *fullpath;
for (NSString *apath in filePathsArray )
{
fullpath = [documentsDirectory stringByAppendingPathComponent:apath];
vedioURL =[NSURL fileURLWithPath:fullpath];
}
NSData *urlData1 = [NSData dataWithContentsOfURL:vedioURL];
NSLog(#" url data1 %# ",urlData1);
NSLog(#"vurl %#",vedioURL);
MPMoviePlayerViewController *videoPlayerView = [[MPMoviePlayerViewController alloc] initWithContentURL:vedioURL];
[self presentMoviePlayerViewControllerAnimated:videoPlayerView];
[videoPlayerView.moviePlayer play];
I tried with some mp4 Examples worked for me
//download the file in a seperate thread.
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
NSLog(#"Downloading Started");
NSString *urlToDownload = #"http://techslides.com/demos/sample-videos/small.mp4";
NSURL *url = [NSURL URLWithString:urlToDownload];
NSData *urlData = [NSData dataWithContentsOfURL:url];
if ( urlData )
{
NSLog(#"urldata %# ",urlData);
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [NSString stringWithFormat:#"%#/%#", documentsDirectory,#"demo2.mp4"];
//saving is done on main thread
dispatch_async(dispatch_get_main_queue(), ^{
[urlData writeToFile:filePath atomically:YES];
NSLog(#"File Saved !%#",filePath);
_url = [NSURL URLWithString:filePath];
});
}
});
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
I need to save all of audio and video url's into document directory which comes from the server. i have tried a sample code
NSData *urlData = [NSData dataWithContentsOfURL:[NSURL URLWithString: "http://www.ebookfrenzy.com/ios_book/movie/movie.mp4"]];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *dataPath_ = [documentsDirectory stringByAppendingPathComponent:#"/MyFolder"];
NSString *newStr = [#"test" stringByAppendingString:[NSString stringWithFormat:#".mp4"]];
NSString *FilePath = [NSString stringWithFormat:#"%#/%#",dataPath_,newStr];
[urlData writeToFile:FilePath atomically:YES];
The folder is creating in document directory but the video is not saving into the folder.Can anyone help to sort this out.
You should build the path properly and you should do some basic error checking:
NSData *urlData = [NSData dataWithContentsOfURL:[NSURL URLWithString: #"http://www.ebookfrenzy.com/ios_book/movie/movie.mp4"]];
if (urlData) {
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:#"MyFolder"];
// Create folder if needed
[[NSFileManager defaultFileManager] createDirectoryAtPath:dataPath withIntermediateDirectories:YES attributes:nil error:nil];
NSString *filePath = [dataPath stringByAppendingPathComponent:#"test.mp4"];
if ([urlData writeToFile:filePath atomically:YES]) {
// yeah - file written
} else {
// oops - file not written
}
} else {
// oops - couldn't get data
}
