Newbie here. Want to learn Objective C. Which book would you recommend?

Hi all,

I am new on here.

I Would like to learn how to develop apps for iOS.

I Understand that iOS apps are made using Objectice C, therefore I want to learn it. What book would you recommend ?

I only have experience with HTML/CSS and Visual Basic. So not got much experience with programming although I understand basic concepts...

Any advice about learning how to program in Objective C?

Also, is there a free version of the software where the app can be developed and tested for Windows (without submitting to the app store). The reason I am asking is because I don't own a mac at the moment. I intend to buy one in September though 🙂

I'd appreciate any help.

Thanks in advance
