Sams Teach yourself Iphone development in 24 hours

Hello I just purchased the book a few days ago and i was entered the second hour chapter I was able to build the sample app "Hello Xcode" as I went a little further into chapter it was wanting me to open a code from a download file called "Hello Iphone Simulator" I am not able to find that application and when I tried to do the zoom in zoom out and rotate with my app it didn't work because of lack of code. From what I was reading it appears that I should have the application somewhere but not sure how I would have downloaded something from Sams guide. Also the picture .png file was having me select the icon.png file and that was not available either. Can someone please let me know if I am missing something regarding this 2nd chapter. Thank you

I guess Chapter 14 really is a problem. I have been following the chapters in the book pretty faithfully and getting knowledgeable for the most part. It is written for v3 of the SDK. Some of the minor differences with 4.0 make it interesting to convert. I am unable to get the chapter 14 project working. His sample from the download works without issues but, I am unable to get the table to display in my version of the project. No errors. It just does not display the table.

I placed a breakpoint within the numberOfRowsInSection method and it does not seem to be executing this method since it does not pause on the breakpoint. I have verified that all links have been properly set by comparing to John Ray's version. Not sure what else to do. My description of the problem is pretty thin I know but, if anyone has some thoughts, please let me know.

Thanks
Jim

Hello all,

The biggest problem with the book (I authored the first half) was that the writing style that the other author used didn't mesh well with the first half. The iOS 4 revision starts to address that (I'm pretty pleased with my new backgrounding chapter), but I know that there is a distinct difference between the first and second half of the IOS 3 edition.

I'm trying to clean it up as quickly as I can, but production schedules are ... challenging. If you have any questions, please feel free to email me directly at johnray@Mac.com.

Thanks!
John

This is my first forum post and I am new to Apple in general and Iphone development in particular, although I do develop apps in Delphi under windows for the oil industry (professionally).

There is a huge amount of support stuff on the internet and I have run through some examples. However I spent ages trying to find the class folder for one example which was based on the older version of xcode.

I borrowed this book from the library and again it doesn't have the ios 4 formats but a book has the advantage of easily going back 10 pages to check up on something rather than tryign to find the previous document your were looking at. Also a book uses no screen space so you aren't trying to fit it alongside your codes , interface designer etc.

This approach, and I haven't got to chapter 14 yet, does give step by step examples and lots of screen shots. I am looking at buying it since its due back in a few days. Unless someone else has a better suggestion.

I can see there is a steep learning curve in all directions - the language, interface, cocoa library etc. so 24 hours won't do it. But 24 1 hours lessons may get me a good start.
