Answer 1

use this code to download text file
NSURLRequest *theRequest=[NSURLRequest requestWithURL:theURL
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:10.0];
NSData *returnData = [NSURLConnection sendSynchronousRequest:theRequest returningResponse:nil error:&urlerror];
NSString *file = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];

///do request like this
NSString *strUrl=[NSString stringWithFormat:#"your url"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:strUrl]];
downloadConn = [NSURLConnection connectionWithRequest:request
delegate:self];
[downloadConn start];
-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse * )response
{
responseData=[[NSMutableData alloc]init];
}
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[responseData appendData:data];
}
-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
NSLog(#"%#",[error description]);
}
-(void)connectionDidFinishLoading:(NSURLConnection *)connection

Get your response in NSdata and write it as follows
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *dataPath = [path stringByAppendingPathComponent:#"yourfile.txt"];
dataPath = [dataPath stringByStandardizingPath];
[responseData writeToFile:dataPath atomically:YES];
}
