The code throwing the error follows: - (vo...
Is it possible to observe (subscribe to) changes to values stored under different keys in an NSMutableDictionary? In my case the keys would already exist when the subscription is initiated, but the values change and I would like to be notified in this case. I would like the key of the changed value in the notification. I assume that if ...
Is there a more efficient way to add objects to an NSMutable Dictionary than simple iteration?

I have the base for my code all setup, it is a drill down table with navigation controller which loads data into a nsmutabledictionary from a plist with some empty values, on purpose.

When looking at the documentation, I hardly see any big difference. Both "value" and "object" are of type id, so can be any object. Key is once a string, and in the other case an id. One of them seems to retain the object, and the other don't. What else? Which one is for what case? ...

The code errors with "incompatible pointer type" - I assume this is because setObject would be expecting an object.. Here is the code - I am trying to have a Dictionary containing my level data: NSMutableDictionary *level = [[NSMutabl...

The source for this dictionary of arrays is an array containing store names sorted alphabetically: Apple Store Atlanta Bread Company Borders Build-A-Bear Workshop...
I have NSMutableDictionary object say obj. When I write it to the disk using [obj writeToFile:filename atomically:YES] , the file does not get written to the disk. But the same set of statements work for a smaller mutable dictionary. The first obj is (nonatomic, retain) property object of a class. The second smaller obj is a temporary ...
I choose index of an array from a plist. It's a dictionary with 10 different line with string. NSArray* tableau = [NSArray arrayWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"codes" ofType:@"plist"]]; NSDictionary* phrase = [tableau objectAtIndex:nombreChoisi]; I would like to take 6 elements and put them in 6 labels...
Hi everyone, I'm trying to look through a NSMutableDictionary loaded with an NSMutableArray and I'm messing it up, and I don't know how. I'm trying to load a larger plist of game questions, then delete them if they aren't the right level. I don't get an error until I try and delete. Can anyone see the flaw in this code? I'd super ap...
Hey all, So, in my iPhone app I was using integers to keep track of a lot of variables. I declared and initialized them all in my AppDelegate file (it's a multiview app), and then if I declared them in the other views (classes) and the values would stay the same. In this way, I could set Money = 200 in the App Delegate file, and then ...

Could someone please clarify for me the semantic difference between these two: self.foo = [NSMutableDictionary dictionaryWithCapacity:theCapacity]; self.foo = [[[NSMutableDictionary alloc] initWithCapacity:theCapacity] autorelease]; Are the interchangable? If not how exactly do they differ. Thanks in advance. Cheers, Doug ...
