please see my above code ,just tell me about custom cell ....
Inside your table view method of cellForRowAtIndexPath. You need to replace this code with your custom uitableviewcell class. And then inside this you need to create nib file and load inside the cellForRowAtIndexPath method.
//Comment this code
// UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
//Modify the same above code with below mentioned link code.
