How to download the mp3 file from webserver into my iPhone app?

I have a list of mp3 files on server.

Now I want that when the user clicks the 开发者_如何学运维button the selected mp3 file should get downloaded into his/her iPhone.

How can it be done?

Any references to articles or tutorials related to this would be really appreciated.

One of the Techniques is using:

 NSMutableURLRequest

You can initiailize a URL Request as the following:

NSURL *URL = [NSURL URLWithString:@"your server url"];
NSMutableURLRequest *request =[NSMutableURLRequest requestWithURL:URL cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:15.0];

NSURLConnection *URLConneSync = [NSURLConnection connectionWithRequest:request delegate:self];

And the delegates of the NSURLConnection:

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
- (void)connectionDidFinishLoading:(NSURLConnection *)connection

Update

On RecieveData Delegate you can do as follows:

 NSFileManager *fileManager;
 [fileManager createFileAtPath:@"Your Path" contents:nil attributes:nil];

  NSFileHandle *FileHandle = [NSFileHandle fileHandleForWritingAtPath:@"Your Path Again"];

Note: you can get the iphone/iPad SandBox Path by using:

 NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
 NSString *sDocumentsDir = [documentPaths objectAtIndex:0];
