Okay, I have several classes in my (somewhat large, and growing) project that
implement the singleton pattern via a [<classname> shared<whatever>] class
method (and a file-scope static reference) that uses lazy loading to
instantiate the singleton the first time a reference is asked for. Is it
considered better to put all of these calls in the main() function before any
other code executes, or not worry about it, and just access them through the
above class methods when and where needed?
Also, in C, it's common to throw away the return value from a function (a la
printf(), which returns an int, but coders rarely use the return value), but is
it good practice to throw away the result of the above method calls (messages)
just to silence the compiler?
i.e.
-(void)someMethod
{
...
[MyClass sharedController]; // No warning here.
...
}
as opposed to:
-(void)someMethod
{
MyClass *p = [MyClass sharedController]; // <- Yellow triangle here for unused
variable 'p'
...
}
TIA! :)
