You created postLength
but never used it, try this it might solve it:
//create URL for the request
NSString *urlString = [NSString stringWithFormat:@"http://localhost/adi/adnan.php"];
//Post data
NSString *post = [NSString stringWithFormat:@"name=%@",@"adnan"];
NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding]
NSString *postLength = [NSString stringWithFormat:@"%d",[postData length]];
//the request
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
//Bind the request with Post data
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setHTTPBody:postData];
