iOS What be the best way to create an app with a list of editable items

Hi,

What would be the best approach to create the app will describe next. I’m not looking for code; I just need to know what components you would use, especially for the item list shown in the picture.

This application is to practice what I have been reading about Objective-C.

What I want to do is to have two UITextfields, one to enter an amount and the other one to enter a percentage, I will also need a button that when clicked, it will do some calculations based on the numbers entered by the user, than displaying the result on a UILabel which is not a problem I can do this without a problem.

My issue is with the item list since I want to display the values entered by the user every time the add button is clicked, I also want the user to be able to edit and delete items in the lists, and as they are deleted or added the total should reflect these changes as well and I don’t know what would be the best way to accomplish this.

An array of UITextfields maybe? Is this how you would do it?

Any ideas would be greatly appreciated.

FYI,
None of this information will be saved in a database or anything like that, it will only be displayed while the application is in use.

Here is a link to a picture describing what I want:

Thanks a lot.

First of all thank you for your reply.

I know this is something really simple for someone with experience, but as I said this is only to practice not a real application.

Thanks a lot for the good suggestions, that is definitely opening my mind more. So far at looks like a UITableview is what I will need as well as an custom object.

This is exactly the type of information I'm looking for.

Thanks a lot

I have been reading the book called Programming iOS 5 and Programming in Objective-C and I feel that if I don't put in practice what I read creating some functinal programs I will never have a good understanding and I wont force myself to work on projects that require challanging tasks, in this case I feel that if I get this done it will open me doors in the programming world.

Thanks

Some of them, but the only one that has exercises is Programming in Objective-C and I want to start doing more with real iOS programming.

I'm actually waiting for the Sams Teach Yourself iOS 5 Application Development in 24 Hours (4rd Edition), I know this one has exercises as it teaches the Foundation.

You don't think this is a good approach to learn? If not, what do you recommend?

Thanks a lot for your help.

I would cancel that order immediately, if possible. I have never heard any good things about that book. I would recommend Apress' Beginning iOS 5 Development instead. It doesn't have exercises at the end of each chapter but the quality of this book series overall is much higher than the SAMS one, I believe.

That’s good to know but why is this book rated higher at Amazon than the one you are suggesting?

Oh, I think your approach is good. It might just be a bit ambitious at this point of your learning curve to attempt editable tables. Get comfortable with the fundamentals of iOS development first. Then you can begin to try some self-initiated challenges.

So, editable tables can be considered a more advanced topic for a beginners?

Thank you very much for your suggestions, I really appreciate your input, it helps me a lot.

Thank you all for your help, I really apreciate your suggestions.

Aren't the Standford courses a little outdated?

I'm going to answer my own question.

It is not, originally I was looking at the first course from 2009, but it looks like the latest is from 2011 which covers Xcode 4, storyboards and ARC which I believe are the most noticeable changes.

I have watched the first two videos and let me tell you, it is awesome, it makes you feel like your are in class. Very well explained, I have a feeling that I will be learning a lot throughout the course.

Thanks a lot.
