I am having a URL in which it contains images and audio files. I am downloading the images and audio files to document directory by using the below code:
// urlsArray contains the list of images and audio urls
for(int i= 0 ;i<[urlsArrray count]; i++)
{
NSString *urlString = [urlsArrray objectAtIndex:i];
NSString *escapedUrlString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURL *url = [NSURL URLWithString:escapedUrlString];
NSData *fileData=[NSData dataWithContentsOfURL:url];
NSString *urlstring1 = [url absoluteString];
NSArray *parts = [urlstring1 componentsSeparatedByString:#"/"];
NSString *fileName = [parts objectAtIndex:[parts count]-1];
NSFileManager *fileManager = [NSFileManager defaultManager];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDir = [paths objectAtIndex:0];
NSString *savedImagePath = [documentsDir stringByAppendingPathComponent:fileName];
[fileManager createFileAtPath:savedImagePath contents:fileData attributes:nil];
NSLog(#"files Stored Path is %#",savedImagePath);
Now I want to seperate the images and audio files. I want to download images to document directory and audio files to cache directory.

Answer 1

Just add following code to recognize the file whether it is image or audio file
CFStringRef fileExtension = (CFStringRef) [file pathExtension];
CFStringRef fileUTI = UTTypeCreatePreferredIdentifierForTag(kUTTagClassFilenameExtension, fileExtension, NULL);
if (UTTypeConformsTo(fileUTI, kUTTypeImage)) NSLog(#"It's an image");
else if (UTTypeConformsTo(fileUTI, kUTTypeMovie)) NSLog(#"It's a movie");
else if (UTTypeConformsTo(fileUTI, kUTTypeText)) NSLog(#"It's text");
else NSLog(#"It's audio");

OK if you separate from your array then do as below:
imagelist = [[NSMutableArray alloc]init];
videolist = [[NSMutableArray alloc]init];
for(int i = 0;i<urlsArrray.count;i++)
{
id arrayElement = [fileArray objectAtIndex:i];
if([arrayElement rangeOfString:#".mp3" ].location !=NSNotFound)
{
[videolist addObject:arrayElement];
NSLog(#"videolist..%#",videolist);
}
else([arrayElement rangeOfString:#".png"].location !=NSNotFound)
{
[imagelist addObject:arrayElement];
NSLog(#"imagelist..%#",imagelist);
}
}
