All my audio render callbacks use the C-function-pointer-to-call-named-selector
trick in JambaLaya. (http://audiofreakshow.com)
In fact, the entire app is written in Objective-C. Between SnoizeMIDI,
MTCoreAudio, and my own private TBAudioUnits framework - I deal with C or C++
almost never.
Hello, Lists,
When creating my document-based application, there is a default menu
item, Format->Font->Baseline. select text on the text view, then click the
Raise or Lower menu, I find something that I can not understand.
Click Raise menu first, the space between the lines increase.
Documentation? "NSNull" does not appear in the documentation.
http://developer.apple.com/mac/library/documentation/cocoa/reference/CoreDataFramework/Classes/NSManagedObject_Class/Reference/NSManagedObject.html
NSNull is conceptually the wrapper for nil, like NSNumber is the wrapper for a
number.

What you're essentially suggesting is putting this code in the model and I
don't think it goes there. The various strings that get displayed on the view
are for the purposes of the view only. They don't have any use in the model.

Why do you think Objective-C has too much "latency" for audio? When properly

Because you're passing the address *of* the local variable, not the

Hi!
Let's suppose I would like to know the current preferred language. I'm using
the following code:
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSArray *languages = [defaults objectForKey:@"AppleLanguages"];
NSLog(@"Languages: %@", languages);
Carbon was originally Pascal based, at least as far as the APIs. It does not
essentially matter what it is written in, just what APIs it supports. If it has
been rewritten in C++ (are they mad?), that should make no difference to
whatever developer language is used, and would not be an argument

If B's value is entirely dependent upon A, you don't even need to synthesize it
— you can just implement B's getter to return A.keypath,

Perhaps it's my misunderstanding, but I can't activate window title
