any idea why? I exactly followed your steps!

Thank you John for your quick response. I looked into Flickr API docs and yes, you could update your query to include your user_id and this will download your own photos as specified. Flickr will provide the method for you. It’s hard-coded and I haven’t played with it too much but it seems pretty easy to use.
thanks again.

Hi Gina, if I recall correctly, the demo app I wrote does a simple search of flickr photos, not specifically photos for your flickr account. I imagine there is a flickr API to do this, so the code for searching would need to be updated to query your account. Hope that helps.

Hi John,

This is a great tutorial. I needed to learn JSON and this really put everything together for me. Everything seems to be working and I have a good understanding of how to use it. Thank you so much.

I am having one slight problem with accessing flickr tho. I’m using my api key but am not getting my images from my flickr account. I’m getting someone else’s (which is kinda funny). Any ideas?
Thanks again and I hope you’re still responding to comments.
I’m off to conquer part 3.

Hi John,

I’ve learnt quite a lot from your tutorial, thank you. One thing that confused me at first was at the very beginning of the tutorial where you add a tableview to JSONFlickrViewController.m I think you mean JSONFLickrViewController.h

Thanks for the great tutorial,

Les.

Hi Roy,

You will need to store the data in some type of internal data structure, appending the content each time more data arrives. For example, you could keep an array of objects, an add a new entry each time more data arrives.

Hi John,
This is indeed a great post, very helpful.
I do have a question regarding the method connection:didRecieve…
As you wrote, this function can be called multiple times (it will grab chuncks of data each time), so, how can i work with the data if it is not completed?
for example, the first chunk will have the data abot 15.5 photos (and not 16…), the next chunk will have the rest of the 16th photo, and it won’t have all the beginning of the JSON string…
Any suggestions on how to keep working with partial data in the meantime?

Thanks,
Roy.

John,.. you are a dev god! Thank-you for this well-structured and generous tutorial. My next is to present those thumbnails in a app-’photo’–like grid structure, and replace the slide-in with a new view etc. etc. But your tut has the merit of being sober and to the point ! (and with a bit of humour!) :-)

Thanks John. I will have to see if I can integrate this getInfo API, with the way I am currently pulling the images.
