I am trying to figure out how to save the scores and recall them to a high score page. I am trying to figure out if saving to a dictionary is the best way, or using an array, or what. Plus, how does the dictionary handle ...
At the server end (GAE), I've got a java Hashtable. At the client end (iPhone), I'm trying to create an NSDictionary. myHashTable.toString() gets me something that looks darned-close-to-but-not-quite-the-same-as [myDictionary description]. If they were the same, I could write the string to a file and do: NSDictionary *dict = [NSDicti...
I've read in Apples docu that (as I expected) an NSDictionary is not constrained just to strings for keys. There's also a post here confirming that Sets can be used. I want to use protocol objects but it' not happening. I initWithObjectsAndKeys and pass @protocol(MyGreatProtocol) as a key. Compiles but I get a runtime error saying someth...
I have an NSArray containing several NSDictionaries. I have an NSString containing an ID string. What I'm trying to do is iterate through the NSDictionaries until I find the object that matches the NSString. Then I want to return the entire NSDictionary. I'm fairly new to iPhone development, so I'm probably missing something obvious.....

What happens when you try to add to an NSMutableDictionary once it has already reached its capacity limit of objects? Does this bump one out or is this going to throw an exception? Also is there any way to have it bump out the oldest dictionary object when I add a new one? ...
Is there any way to create a mutable dictionary with a capacity limit rather than an initial capacity? Say you want to create a dictionary that will only ever have, at most, 100 entries. The capacity argument for the dictionary is an initial capacity that will be simply increased if you add more elements than you want so it's not suita...
How would I search my dictionary for the closest value to the query? Say I search for 0.000475, I know it's not available but I want to return it's closest value 0.000500. I suppose I would use keysOfEntriesPassingTest to achieve this on a dictionary, clueless on how to go about it though. <key>1/8000</key><real>0.000125</real> <key>1...
Hi, I would like to get all the extensions of files my app can open. And I'd like to get them from my Info.plist. Right now I have this, but is there a better alternative?
