I am trying to create a NSMutableDictionary(dictA) with objectA. When I try to view my dictionary(NSLog), each key is pointing to the same address. I have an objectA_1 which is type objectA and used to setup the dictionary. Also, if I try to getObject, I always get the last key/value that was added to the dictionary. I tried setValue...
Hi. I use an instance of NSXMLParser. I store found chars in NSMutableStrings that are stored in an NSMutableDictionary and these Dicts are then added to an NSMutableArray. When I test this everything seems normal: I count 1 array, x dictionnaries and x strings. In a detailview controller file I want to show my parsed results. I call t...
Okay, coming from a perl background I am used to Arrays holding refs to Hashes (Dictionary in iPhone parlance). What I would like to know is this: If I have a NSArray of NSMutableDictionaries. Say I added the following NSMutableDictionary to an NSArray: [theArray addObject:[[NSMutableDictionary alloc] initWithObjectsAndKeys: timest...

Hello Everyone, I would like to access some values from a CFMutableDictionaryRef and then do some math on them. Using the code below I have managed to print some properties of my battery.

Hey there, my app has a search bar that searches a plist file.

I've been trying to implement NSXMLParser and so far I've had memory issues, performance issues or it doesn't work. I worked originally from a example off the net and it leaked a heap of memory. I released the objects properly but found that there was a performance hit because I would alloc and then release each object for each element....

Regards, B ...
Hi there, I would like to be notified, when an NSMutableDictionary's count reaches 0. Is that possible without extending NSMutableDictionary (which I heard you should not really do)? Could I e.g. have a category that mimicks remove methods by calling the original ones while checking whether count is 0? Or is there maybe a simpler way. ...
I have a series of models for my application. Across all these models there are (will be) some 200 or 300 instance variables. The application stores its persistent data on a web-based server (MySQL - but I guess that part doesn't matter). Whenever a model iVar is updated I need to make a call to the server to update the appropriate value...
