Y did u make and IBOutlet and IBAction for the button? The button is IBAction only. Anyways, nice implementation of the delegate.

@mahmed555 I think it is not ! Our controller use two delegates textfield and alertview delegates. we just use them. that is why in our example we first use a button and then the delegate function instead of it.

I have started ios 3-4 months ago also. Vivian your videos are very informative and clear. Especially i like your doing them in coding part not just drag and drop in IB. So we can do lots of custom things. I am going to put at least 5 applications to App Store nowadays for kids and youngs

@richardlipp21

I think that our controller is the delegate (for the textfield and alert) because we are implementing the delegated functions ourselves in our own code. I may be wrong though (since I am a newbie myself!!!!!!)

Thanks. Your videos are excellent (much better than many book's examples). You get to the point very clearly. The IB vs Code parallels are super!

Somewhere between Tutorial 3, 4 and 5, I expected a little more discussions on the Wndows, Views, and view controller's roles. Perhaps I missed some videos. I did not find any discussions on the role of Interface Builder (in the initial stage).

Thanks again for excellent work!
