Passing variables to an AppleScript

Question

The code to run my AppleScript in Xcode is the following:

NSString *path = [[NSBundle mainBundle] pathForResource:@"Script" ofType:@"scpt"];

NSAppleScript *script = [[NSAppleScript alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:nil];

[script executeAndReturnError:nil];

Before executing it, I was wondering if it was possible to set some variables up for it to use. In other words, I want to pass variables from my app to an AppleScript.

You could use the method:

- (id)initWithSource:(NSString *)source

and use stringWithFormat to build your applescript source and setting the arguments.

NSString* scriptTemplate = ...;
NSString* actualScript = [NSString stringWithFormat:scriptTemplate, arg1, arg2, ... argN];
NSAppleScript *script = [[NSAppleScript alloc] initWithSource:actualScript];

You could also devise a more advanced replacement mechanism, where you tag somehow your parameters in "Script.scpt" and then replace them using stringByReplacingOccurrencesOfString:withString:
