How did you learn this stuff? Since this tutorial is so good. Did you read a book on it and if so what was it?

[macheads101]

@ACSspartan You can learn the basics from a book, but getting good at it requires lots of time and practice. Two years ago I released my first app to the app store. Only now do I consider myself good at iPhone programming. There are a few books, but for iphone programming I recommend the iPhone Developer's Cookbook

i tried running the program after you taught me how to make it, there were four errors

WTF

[macheads101]

@Dudeman0911 Can you PM me with the errors that you have? You probably copied something wrong from the video.

[Dudeman0911]

@macheads101 i figured it out, but thanks anyway. BTW i really love this video series, so could you make a video that is about trouble shooting the program if there's errors?

Thanks

[macheads101]

@Dudeman0911 It is among the things i have considered. If i make the video, it will probably be a list of errors or situations, and what the errors mean. mind sharing the error that you had?

A reset button for this would be nice.

@isseswe You should make two IBOutlets (one for each label). Then make two IBActions (one for each buttons). Have each IBAction change a different UILabel. PS: when I say different, I mean with a different name.

[isseswe]

I'm trying to make two buttons changing two different labels. Can I duplicate the codes and just paste them? And if I can, where should I paste them?

[macheads101]

@j1mmyarts one outlet cannot point to multiple labels. you will have to use multiple IBOutlets.
