I am having a small issue in my application. I have it to where when the user presses the facebook button the SLComposeViewController pops up with text in it that I have preset. That is where my problem comes in. I would like it to say I just climbed and then at the end, whatever climb that they pressed into. Example: I just climbed Mount Everest. The I just climbed part I can get to show up, but when I try and use stringWithFormat it gives me an error which I will post below, along with my code. The climb title is set a a label in my DVC with this line self.titleLabel.text = self.climbTitle;
Line with problem:
[mySLComposerSheet setInitialText:NSString stringWithFormat:#"%#Climbed", [_climbTitle];
Error:
DetailViewController.m:79:39: Unexpected interface name 'NSString': expected expression
I hope I have worded this question appropriately and have given enough context for everyone to understand my issue, if I haven't, please inform me and I will correct it.
Thanks
It should be [NSString stringWithFormat:#"%#Climbed", _climbTitle];

Iam getting a number of errors, please help me out. I am budding developer...
You've put a closing brace } after the email IBOutlet which signifies the end of class scope at that line. Remove that.

For some odd reason, following code does not take effect, I changed the size to 20.0, but the size of the text does not increase. I do not know what might be the cause of the problem. Please help.
[cell.textLabel.text sizeWithAttributes:#{NSFontAttributeName:[UIFont fontWithName:#"Helvetica Neue" size:8.0]}];
sizeWithAttributes does not "do" anything. It does not "take effect" or "increase" anything. When you call sizeWithAttributes you are asking a question. And it gives an answer - it returns a size.
It happens that you are throwing that answer away (you never capture it). Thus, your call is pointless, though not formally an error (it is not a compile error or a runtime error to fail to capture a return value - it's just silly).
But the main error you're making is in not reading the docs; you are evidently calling this method with a sheer fantasy idea of what it might do. Don't guess! Read what the docs tell you.

I’m planning on using a UIWebView for my app, and making it more user friendly by having a “reader” version of the webpage. Does anyone have any idea how to do this?
Here’s an example taken from the reddit app that displays a regular webpage, then when you press a button, it transforms the page into a “reader” version. (like how safari does it). Thanks!
I don’t know of any API for UIWebView or a third-party library, but many apps use Readability Mobilizer, Instapaper Mobilizer, or Google Mobilizer. Just pass your URL to one of these services, and load the resulting page.

Edit: I implemented this again and I am getting this error.
I am working with Concerns. I took out some code of my app/models/user.rb and placed it into app/models/concenrs/following.rb. The source codes can be found on Gist, here.
When I go to /dashboards I get this error on timeline.rb (i uploaded this file's code on Gist too).
undefined method `followed_user_ids' for #<User:0x4f6cfc8>
The error is on line 15 of timeline.rb.
The project can be found on Github.
This seems to me that it does not load the module. Any clue?
You wrote ActiveSupport:Concern instead of ActiveSupport::Concern (notice the double colon).

Trying to use \ref{} or \autoref{} to a label in an appendix, but it just shows up as empty with \ref{} and 'Section' with no number/letter for \autoref{}.
I'm not sure if I'm misreading examples out there, or if I have a package conflict...
% MainFile.tex
Details of obfuscation of evil are provided in \autoref{app:One}.
\appendix
\section{Obfuscating Evil via Optimized Confusion Matrix} \label{app:One}
Recall that the ....
Shows up in pdflatex output as "are provided in Section ."
Try recompiling the document. If the label is after the reference, you need to compile twice to get it to work.
If that doesn't work, this page might help. In short, \usepackage{appendix} and possibly \begin{appendix} etc. might fix it. If it's just a matter of the reference showing up, I can't see how this would help actually, but it might. Without a minimum working example it's hard to give much more advice.
You might also have more luck asking your question here.
