Hi, Someone on IRC told me I could create objective c objects directly from plist files in such a way that I don't have to specify strings everywhere for serialization/deserialization of the plist. Does anyone know how to do this? I'd like to simply have a plist like this <array> <object> <id>my unique id</id> <description>...
I'm working through an idea for an iphone app. One of the tech requirements I'm considering is the need to send a short data message to another iphone running the same application within range, but this would need to happen transparently. I don't have 2 devices to test (yet, obviously I'll need them eventually), and haven't been able to...

Imagine a UILabel, which is 200 pixels wide and 50 pixels high. The label has text inside, and the label makes the text smaller so that it fits into the label. But now, how would you get the size of that UIFont how it is visible in the label? Lets imagine the font size was given with huge 100, and the label squeezes it down to 15. And th...
I want to create an object in Objective C but I don't hold a reference to it. Is it allowed to let the object control its own lifetime by calling [self release]?

I need a representation of µ or "micro". That funny small u with the long tail on the left side. Maybe you can see it here: µ Some weeks ago I was reading in the docs, that it's a bad idea to type any special characters into the source code. So to prevent problems, could I encode that special character µ somehow like web folks do with ...
hi, i am building an application that imports JSON results and parses the objects to a table cell. Nothing fancy, but in my results, many of the terms/names are European with characters such as è or ú which come out as \u00E9 or \u00FA. I think these are ASCII ? or unicode? ( i can never keep em staight). Anyway, like all good NSSTring's...

Since KVC is used to set outlets on the iPhone, there are 2 methods (that I know of) to make sure you've properly handled memory management. Specifically, I am referring to this article written by Aaron Hillegass. My question is which method do you use and what is your reasoning? Release all your outlets in dealloc and viewDidUnload ...
