Truncated tweets iOS - ios

Question

I am putting a twitter feed in my app and no matter what I have tried to do to get the tweets to display in their entirety, I have not been entirely successful. Most tweets show up fine but it's the really long ones that have given me a headache. I thought it was because I was somehow not getting enough lines in my textLabel, but I noticed that if a user has elongated their tweet by hitting enter multiple times the tweets would show up fine. Which leads me to believe somehow it is truncating after a certain amount of characters. I don't know if I'm doing something wrong or if this is just an issue with twitter. If anyone can see anything in my code that is wrong, or could be changed to fix this, please let me know. Thank you

Answer 1

After a lot of investigation I found an article somewhere that said there is a difference between the text key and the retweeted_status.text key. The tweets being truncated were, in fact, retweets from the user using the text key. However, the retweeted_status.text key is only the tweet that was retweeted, without the user who originally tweeted it. That sucks because the retweeted_status.text key is NOT truncated. Ahhh, the joys of programming. Hopefully the new twitter API will address this. I hope this answer helps somebody.
Here is the link to what I found in case anyone is interested: http://code.google.com/p/twitter-api/issues/detail?id=2261

Answer 2

I haven't gone through your code, but I thought of mentioning this point that Twitter only allows tweet 140 characters long! This is the basic rule of a tweet. So no matter what you do tweet with mode than 140 characters will be truncated.
I hope this is not the issue?
