I think the URL from tutorial 2 is missing. Code still works, but comes up nil. I’m guessing it is because you changed servers. Also, corrections are in the comments for Tutorial 2 (initWithContentsOfURL), but would be nice to have them in the body of the article.

Thanks so much for doing these though. They help tremendously!

Great Tutorial – really helpful for a newbie like me… this site is well and truly bookmarked…

I was wondering why my test was returning (null)… looks like the URL for the text file is offline… Whoops..

Collin, please correct this lovely tutorial so it will be a great
tutorial.

// right
NSString *myString = [NSString stringWithContentsOfURL:myURL];

// right
NSString *myString = [[NSString alloc] initWithContentsOfURL:myURL];

//wrong
NSString *myString = [[NSString alloc] stringWithContentsOfURL:myURL];

initWithContentsofURL should be initWithContentsOfURL

Excellent tutorial! I appreciate you taking the time and effort to produce the examples. I am coming from programming Windows Mobile (C#) and you are making the switch very pleasant. Happy coding!

Well, I think you might just have a new reader, finaly an easy beginning of cocoa and objective C, not that I can’t program (I’m pretty advanced with PHP, (OOP, MVC and other design patterns)) but somehow couldnt seem to get the grasp of Objective-C.

Read lots of documentation from Apple, and looked at some PDF books, but none where really clear, this is

Is nesting broken/deprecated in the latest SDK?

Um, wow. Absolutely perfect. I’m a management consultant and this is an amazingly great educational report. Things were structured, clear, and are set up from the perspective of the reader. You have my vote of confidence and just found yourself a loyal reader/subscriber (your feed has been added!) Thanks a ton.

Hi, this tutorial is exactly what I have been looking for – please get the link to the screencast working again!

Great site BTW.

I was looking for the screencast as well. Would appreciate it you could let me know when it’s back up! Thanks!

The link appears to be broken again, could you post the screencast on Vimeo instead?

Fantastic tutorial and glad I finally found it after stumbling on a lot of halfway tutorials out there. I was feeling pretty dumb with a decent background in C++ and Java and absolutely NO clue what was going on in some of the sample code I was trying to decipher.

This tutorial has been a Rosetta’s stone for me and I look forward to checking out the follow up I saw before.

Thanks Collin!

Perfect timing on this. I started playing around with iPhone development and realized that I didn’t know enough ObjC to get by. So I’ve been out scrounging around the internet looking for good tutorials.

hey collin,
im coming from a vb6! background and trying to immerse myself in objective-c with the hope some of it will stick.
really enjoyed your tutorial, i think you did a good job pitching to newbies (where nearly everyone else falls over at the starting block)
cheers

Great post. BTW, the change to initWithContentsOfURL hasn’t been put into the code for example 2 yet

Keep up the good work!

Awesome tutorial! Thanks for that very informative introduction to Objective-C.

Hey Fernando,

Great question. I use the documentation in xCode. This can be reached by going to Help -> Documentation and then searching. OR you can hold option and Double Click on a Class name such as NSString to bring up that specific class and its related methods and attributes. I will make sure to include this in the next screencast

Thanks for reading!
