user_timeline NSURL

just a heads up, if you use https as the book shows in section 3.3 of the reloadTweets method you’ll get an authentication error response. the book shows

NSURL *url = [NSURL URLWithString:@”https://api.twitter.com/1/statuses/user_timelin…];

change it to:

NSURL *url = [NSURL URLWithString:@”http://api.twitter.com/1/statuses/user_timeline…];

not sure if this is an errata type issue or not but i thought somebody else could find this useful.

I didn’t experience that when writing it, but it’s possible that I authenticated my simulator doing something else and therefore didn’t get hung up on the https:. If http: works for you, that should make things simpler for everyone. Please file this as an errata. Thanks.

using HTTPS works for me. I noticed a couple of things that confused me in this section. When specifying the “twitterParams”, in the book it showed:

"pragprog", “screen_name”

But if I want to see my tweets, then “pragprog” must be my Twitter screen name.

I found the Twitter API documentation, some of the best I have used as it is so amazingly complete (https://dev.twitter.com/docs/api) and it did not take much effort to locate the API being used in your book which I did not know if it should be referenced in your book or not:

https://dev.twitter.com/docs/api/1/get/statuses…

This statement is incorrect as it should be “queue” instead of thread>

To try it out, change the dispatch_get_main_thread to dispatch_get_current_thread.

Rick: yes, I think we mention earlier in the chapter that you need to use your own screen_name… we included “pragprog” in the sample code because that’s what we generated the screenshot from (I think on the first mention, we had “yourtwitterhandle” as a dummy value).

Thanks for the point on dispatch_get_current_queue()... this has already been filed in the errata.
