I was getting a little confused with typedef/enum until I realised that I did not need to name the emun. Are there any differences / benefits between these two when used with typedef, the 2nd one to me seems a lot easier to understand.

Greetings, I'd like to convert a PointPoint file to PDF using C/Objective-C (bonus points if you suggest a solution that could run on an iPhone directly). There are a number of Java libraries to work with MSFT files (odftoolkit, apache poi), but I'd really like to perform this operation on an iPhone device. Apple has built in libraries...
I'm creating an app in which I do the same thing multiple times. I'm going for as little code as possible and I don't want to repeat myself. I need the PHP equivalant of a reusable function, where I set an input, and the function will return the output. The app is a URL shortener, so the input as you may assume is a URL, and the outpu...
I've read that as of iPhone OS 3.1, GameKit supports wifi connections. But the documentation states: "If your application configures the peer picker to allow Internet connections, your application must also dismiss the peer picker and present its own interface to configure an internet connection." Does this still stand? ...

Using UITableView as an example is there a difference between [self.myTableView visibleCells] and [myTableView visibleCells]? Or say [self.myImage setImage:...] and [myImage setImage:...]? I've seen Apple code tha...

I am using @property(nonatomic, retain) for my IBOutlets for an iPhone application. However, I'm not sure how to make sure I'm managing memory with them properly. The IBOutlets are all set up in Interface Builder, so I'm never calling alloc manually. This means that I'm not sure when and if to deallocate them or when to set them to point...

However, it seems that my cellForRowAtIndexPath method is not called when the tableview is created, so my table never gets populated. What am I missing here? (All labels are init...
This is a snippet of some code that I've been having problems with. I have an iPhone app that works fine for 99% of my users, but for maybe 1%, I have this bug which I can't resolve or reproduce on my end. The app just freezes for them, and doesn't actually crash (so no crash reports). Some ad-hoc distribution testing has revealed the pr...
