Answer 1

Use this code instead of your code it gives the string output ,then you have to format that string to get disired output.
NSString *post =#"";
NSURL *url=[NSURL URLWithString:#"http://nyxmyx.com/Kinkey/KinkeyPHP/lastidretrieve.php"];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody:postData];
NSError *error = [[NSError alloc] init];
NSHTTPURLResponse *response = nil;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
if ([response statusCode] >=200 && [response statusCode] <300)
{
//NSData *data = [responseData resourceDataUsingCache:YES];
NSString *string = [[NSString alloc] initWithData:urlData encoding:NSMacOSRomanStringEncoding];
NSLog(#"responseData-%#",string);
}
Output will be like this.
responseData-1995<br />prabu<br />1231231233<br />antab<br />8080808080<br />1360738531881.jpg<br />No
UPDATE
In case you want to add argument in your URL than change post string to this.
NSString *post =[[NSString alloc] initWithFormat:#"yourArg=%#",yourArg];

It would have been sufficient to read the documentation of NSURL. This method is deprecated. You should use [[NSData alloc] initWithContentsOfURL:url] instead.
