Hi, I'm working with the iPhone SDK and am trying to gather and store a list of all addresses within a given radius (the radius will range from .25 to 19.75 miles). understandably the larger radius would produce a large amount of results, but for now I'd like to at least be able to do it for a mile or so. The end result would be to have...

Hi, I'm working with NSXMLParser that parses a xml document. You have to set the delegate which we would be called every time the parser finds an element. The examples I've looked at all set the delegate to be the same class that's createing: NSXMLParser *parser = [[NSXMLParser alloc] initWithContentsOfURL:filename]; [parser setDelega...
Hi Guys, Is there a relatively easy was to include a 3D animation into an iPhone app? We have the animations already made up for another project and our client has asked if they can be placed inside an iPhone app. We could perhaps include a low-res looping video of the animation (it's just a 3D component rotating on a single axis), or w...

note: This is an expansion (and clarification) of a question I asked yesterday. I am conducting a research project where I want to record all of the user's touches in the iPhone app. After the experiment, I will be able to download the data and process it in either Excel or (more likely) Matlab and determine how many times they clicked ...
I'm interested to know if I can have access to all the libraries, ide, etc for the iphone/ipad/macos without paying the 90 bucks(for learning purpose). Do I have to pay to have access to everything in order to start developing? I'm not talking about the istore by the way. I know that there is a fee for that. Thanks. ...
When I try to get the bounds of the main screen with [[UIScreen mainScreen] bounds], it returns null. I've tried with [[UIScreen applicationFrame] bounds] as well, still returns null. The strange part is; if I do "NSLog(@"%@", [UIScreen mainScreen]);" it prints out the correct bounds, albeit I have no idea how to parse it, if it's even p...
In Objective-C, is it possible to access instance variables and methods from within the scope of a static c function? I feel like there is probably a simple answer to this that I'm overlooking, but I'm still fairly new to this language. Consider the following stripped down code: @implementation MyObject static int ammoHitSensor(cpArb...

Hi, it is possible and rather easy to create a NSPredicate from a string that uses the contains operator, like this: [NSPredicate predicateWithFormat:@"name contains[cd] \"Hello!\""]; I would like to create this predicate programmatically, as it can be done for comparisons with the NSComparisonPredicate. Any ideas about this? My mot...
