title: How long did it take you to learn Objective-C probably?
body: <p>I have a question I really want answered. I have been playing around with some Objective-C for a few weeks, and I have been reading in the book <a href="https://rads.stackoverflow.com/amzn/click/com/0321503619" rel="nofollow noreferrer" rel="nofollow noreferrer">Cocoa Programming for Mac OS X</a> until Chapter 7.</p>
  
  <p>In chapter 5 and 6, there is a challenge you should do, especially chapter 5 where he write: </p>
  
  <blockquote>
    <p>This exercise is an important challenge that you should do before moving on. Although it is easy to follow my instructions, you will eventually want to create your own applications. Here is where you can start to develop some independence.</p>
  </blockquote>
  
  <p>But I have not been successful on those challenges: tbh, I have no idea how to do them...
  It does not even help to look back the previous chapters and steal the code, I have no idea how to make it work and what I should be typing.</p>
  
  <p>So my question is: how long did it take you to probably know Objective-C? For those who have read the book: where you able to do the challenges?</p>
  
  <p>I really want to learn Objective-C program for the iPhone, but now that I don't even know how to do the challenges, I doubt it's possible for me to learn it... Is there still hope?</p>
  
  <p>It should also be said that besides the challenges, much of the code he writes makes no sense to me. I am not sure why he writes it and what it does 100%. Please help me on this one!</p>
  
  <p>Thank you in advance</p>
