I know this has been discussed ad-nauseum but I just don't get some of the memory management. I understand that retain keeps the object alive and copy gives one a separate copy of an object. What I don't get is when it comes to ivars & properties, retain as a property means that the setter releases the old value & retains the new: prop...

I have a class with a string property... @property(nonatomic,retain) NSString * synopsis; I set the string property from some HTTP response, either from JSON or XML response.

I have what I believe is a fairly simple application at the moment based on a few tutorials cobbled together. I'm using XCode 3.2.3 in OSX 10.6.4. It started as a standard iPhone "Window Based Application". Using interface builder I have added a Tab Bar Controller using the O'Reilly video tutorial here: http://broadcast.oreilly.com/2...
[I might be misunderstanding this entire topic, as I've grown up with languages that allow the dev to almost entirely ignore processor architecture, like Java, except in some particular cases. Please correct me if I have some of the concepts wrong.] Reading here it seems that the advice is to use CGFloat instead of, say, float, because ...

Hi, I'm writing an app in XCode 3.2.3 for iOS 4. In my code, I am creating an NSArray of NSDictionaries, each containing two key/value pairs, a string and an NSArray of NSDictionaries (kind of confusing, I know). Just to give you a visual, here is the structure: <NSArray> <NSDictionary> <NSString/> <NSArray> ...
Currently I have an objective-C program that detects when a Fujitsu scanner is added and removed from the computer. I'm trying to add the ability to ask the scanner information about itself. I know the command for this, however, something is going wrong. I'm doing a bit of cargo-cult programming, from two different cargo cults (How do yo...
I have a method to generate a Deck object (NSObject subclass with an NSMutableArray property) and it populates the array with Card objects (UIView subclass with some integer and one NSString property). When I ask for a Deck I check to see if one already exists (I think) and if so, release it before getting a new one. The code from my v...

What am I doing wrong? labeledPemString do has contents and the specified characterSet is printing 'ranges begin {0, 26}' .

Can somebody show me how or lead me to a tutorial to get a request access token pair and make a request to a URL given username, password, consumer_key, and consumer_secret? I'm really foggy with this, and I don't even know why I get a access token pair (why two toke...
So apple has this pretty cool example about how to make a uitableview which cells resemble appStore cells. Code can be found here. Now, the strange thing... I was playing with it, and in RootViewController.m where it was - (void)viewDidLoad { [super viewDidLoad]; // Configure the table view. self.tableView.rowHeight = 73.0...
