Okay please excuse my simple questions:

1) In C++ you can initialize member values inside the constructors implementation using a initialization list, like so (taken from "Effective C++" by Scott Meyers):

Code:
NamedData::NamedData(const String& initName, void *dataPtr)
: name(initname), data(dataptr)
{...}

This allows member variables to get init'ed. I think Obj-C doesn't have constructors, but can you do this kind of thing?

AND...

How are timed events done easily? Is there a wait() function I can use or do I have to use NSTimer and create an Invocation using self as the id?

thanks for reading!

It has what's called the "init" function. Often in the init you'll call the init of the super class and then init your stuff for the sub class.

Like Scott_H said, init is the default constructor. All objects support init. If you want to initialize something with some data, however, you would usually called something like:

[[MyObject alloc] initWithString:@"Moo" lifespan:4];

NSTimers don't lock up your app, like sleep(int) would. You can also specify if the timer repeats.

[NSThread sleepUntilDate:[NSDate dateWithTimeIntervalSinceNow:5]];

Will lock up the current thread for 5 seconds, then proceed to the next line.

The syntax for an init function is like this:

- (id)init {
[super init];

<<specific initialisation stuff>>

return self;
}

You must put super init and return self in otherwise it won't work properly, I don't think.
