At the moment I’m making a book for the iBook store as I have photo content I think might sell. I’ll soon learn the Apple upload process separate from the programming aspects. :-) B I will keep in touch. Thanks again.

my real advice is get one of the Apress books – there are others (pragmatic programmers and indeed stand ford do a course on iTunes video) but i used these (i have no commercial links) work through the chapters – the introduction book in particular is written as a course.

Download the source code and then play with it. try and get it to do more than what the book does. so if the book puts a square button on screen and interacts with it – you learn how to put every type of button on screen. I spent about 2 months doing this in my spare time (I’m a doctor by day) and then decided to write a really simple app that i give away free (uploading stuff to apple can be a nightmare in itself with the distribution certificates etc – but thats another story!)

at this stage you are then probably much better prepared to create your app.

you gain so much from looking at others code – actually seeing how programmers deal with things. for example ive never seen anyone use nested if then statements like you have above. look up the Case statement which does what you are trying to do much more elegantly and a lot less confusingly.

also the whole way oop is done is you can often lift whole sections of other peoples code to use as your own saving you time. in deed certain types of code are prebuilt for you if you select the right program type.

hope this helps – interested to hear how you are getting on.
