Hi, I have a simple class with an NSMutableDictionary member variable. However, when I call setObject:forKey I get an error ('mutating method sent to immutable object'). The source of the problem is obvious from the debugger -- my NSMutableDictionary is actually of type NSDictionary. I must be missing something incredibly simple but c...
Currently I am working on a production app. One function acts like the settings.app on iPhone. When the user click a cell of a tableView, as shown below http://www.penguintech.net/images/stackoverflow/1.png It will push another view, which includes a textfield to let user input something. However, on both simulator and device, after t...

I know that the Apple community – including Mac and iPhone developers – mainly use Objective-C for their development language. But it seems that not many people use Objective-C outside of the Apple community, such as in the Windows or Linux worlds. What are the possible reasons that Objective-C is not particularly popular outside of the...

I am writing a program in Objective-C (Xcode 3.2, on Snow Leopard) that is capable of either selectively blocking certain sites for a duration or only allow certain sites (and thus block all others) for a duration. The reasoning behind this program is rather simple. I tend to get distracted when I have full internet access, but I do need...

I am looking though some source code from a third party and am repeatedly seeing a syntax that is new to me. Basically they are separating statements with commas instead of semicolons. It compiles and works, but I don't understand what it is doing. It looks like so if(url)[url release], url = nil; and they also use it without the if s...

Several of my view controllers need access to the properties of the dictionaries, so instead of writing duplicate code to retrieve the .plist, convert the values to a dictionary, etc, each time I need the info, I thought a model class to hold the data and sup...
I am using cocos2d to build an iPhone game. It's mostly done, but along the way I came across some things that I would like to handle better. I am fairly new to Objective C, and honestly I do more Perl scripting in my day-to-day job than anything, so my C skills are a little rusty. One of them is the fact that I have modified cocos2d ...
I have a static library (let's call it S) that uses a category (NSData+Base64 from MGTwitterEngine) and a C library (MiniZip wrapped by ZipArchive, a mm file). This static library is used in an iPhone 3.x project (let's call it A). To be able to use the MiniZip library I included its files in project A as well as the static library S. I...
