There are multiple Errors in your Code, Use my Code as a Reference and compare it to yours and you'll get the Errors done by you. The Below code is working correctly from the Point of View of Objective-C. There are some Errors regarding your URL or Service Side.

Working Code :

NSMutableDictionary *dict = [[NSMutableDictionary alloc] initWithObjectsAndKeys:@"ann",@"uname",@"ann",@"pwd",@"login",@"req", nil];
NSLog(@"dict :: %@",dict);
NSError *error2;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dict options:kNilOptions error:&error2];
NSString *post = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];
NSLog(@"postLength :: %@",postLength);
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:@"http://exemplarr-itsolutions.com/dbook/index.php"]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setHTTPBody:postData];

NSURLResponse *response;
NSError *error3;
NSData *POSTReply = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error3];
NSString *str = [[NSString alloc] initWithData:POSTReply encoding:NSUTF8StringEncoding];
NSLog(@"str :: %@",str);
