Now the line
- (BOOL)launchApplication:(NSString *)appName
May be technically the declaration of the method, but is that really
useful to anybody? After all, you do not declare this method in your
code; you just invoke it. I can't tell you how many times I have
been led astray by this terminology - took me at least a year to
figure out that the way it is written has nothing to do with how you
use it.
I'm sorry, I've had some sympathy with yours and others complaints
about the documentation up until now - after all, it's been so long
since I was new at this that maybe I just can't see things through new
eyes - but this is just going too far. How you declare a method
versus how you call a method was something that confused you for a
year? Is that really what you are saying here?
Differing syntax between declarations and calls exists in almost every
programming language ever made. (The only exceptions being languages
that don't have function declarations at all.) If you can't
immediately see the difference and easily translate between
declarations (e.g. "(int)fibonacci(int n)") and calls (e.g.
"fibonacci(12)") then you simply do not know even the most basic
syntax of the language and no framework reference documentation,
however it is written, is going to help you.
