I want to create a constant static array to be used throughout my Objective-C implementation file similar to something like this at the top level of my ".m" file: static const int NUM_TYPES = 4; static int types[NUM_TYPES] = { 1, 2, 3, 4 }; I plan on using NUM_TYPES later on in the file so I wanted to put it in a variable. ...

I was looking at this SO question and got to thinking about const ints versus #defines and realized I don't actually understand why the compiler can't deal with this. Could someone shed some light as to why the following code const int FOO = 10; int main(int argc, char** argv) { switch(argc) { case FOO: { printf("foo\n"...

I'd like (at runtime) to bind a parameter to a function as you can do in boost::bind - a little like the following: -(void)myFuncWithParameter:(NSString*)param { NSLog(param); } -(void)init { UIButton *helloButton = [UIButton buttonWithType:UIButtonTypeCustom]; [helloButton addTarget:self action:@selector(myFuncWithParameter:...
I'm reading pixels from an area of the main screen via NSOpenGLContext. Now I would like to draw a rect around that area to indicate where it actually is. How would I do this? My first thought was the "Cocoa way": create a transparent fullscreen NSWindow and a custom NSView to draw the rectangle path. But that feels a bit too complicated...

I am pretty new to the Objective ...
Hi, I've a string that may or may not include C++ comments on it (multi-lin and single line) and I need to strip those comments out before being able to use that string.
