Thanks in Advance
I tried to store like this:

NSArray *ipaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *idocumentsDir = [ipaths objectAtIndex:0];
NSString *idataPath = [idocumentsDir stringByAppendingPathComponent:#"File"];
NSLog(#"idataPath:%#",idataPath);
//Create folder here
if (![[NSFileManager defaultManager] fileExistsAtPath:idataPath])
{
[[NSFileManager defaultManager] createDirectoryAtPath:idataPath withIntermediateDirectories:NO attributes:nil error:&error];
}
// Image Download here
NSString *fileName = [idataPath stringByAppendingFormat:#"/image.jpg"];
NSLog(#"imagePathDOWNLOAD:%#",fileName);
NSData *pdfData1 = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:[URLArray objectAtIndex:a]]];
[pdfData1 writeToFile:fileName atomically:YES];

You can use NSURLConnection class to implement progress bar:
.h:
NSMutableData *responseData;
NSString *originalFileSize;
NSString *downloadedFileSize;
.m:
- (void)load {
NSURL *myURL = [NSURL URLWithString:#""];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:myURL
cachePolicy:NSURLRequestReloadIgnoringLocalCacheData
timeoutInterval:60];
[[NSURLConnection alloc] initWithRequest:request delegate:self];
}
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
responseData = [[NSMutableData alloc] init];
originalFileSize = [response expectedContentLength];
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
[responseData appendData:data];
downloadedFileSize = [responseData length];
progressBar.progress = ([originalFileSize floatValue] / [downloadedFileSize floatValue]);
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
[responseData release];
[connection release];
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
NSLog(#"Succeeded! Received %d bytes of data",[responseData lengtn]);
}
Let me know for any queries.
