问题
I want to run a simple applescript in a cocoa application. I read the apple documentation on the matter but it was too confusing for me (a beginner) to understand.
tell application "iTunes" to play

Per the documentation, you use the NSAppleScript class.
The very short API reference has a section called "Initializing a Script," one method of which is -initWithSource:, which takes an NSString. You'll create your object this way.
Once you have your script object, you can then either -compileAndReturnError: then -executeAndReturnError: as separate steps, or just -executeAndReturnError:, which - according to the documentation for that method - tries to compile the source first if it's not been already, then executes.
So, in theory, you could probably do all this in one line. (alloc, init..., autorelease, executeAndReturnError:) if you ignore errors like a naughty developer.
Note the warning that NSAppleScript can only be executed from the main thread (ie, not from an NSOperation/Queue or other threads).
