Re: Sending a Javascript Array in Cocoa

If you look at the documentation in the WebScriptObject.h header file, you'll see that an NSArray does turn into a JavaScript array object, but a JavaScript array object does not turn into an NSArray. There are many reasons for this, one being that there are many different kinds of objects in JavaScript that act like arrays, and luckily it's easy to cope with. You can modify your code to be something like this:

- (void)setArrayOfSteps:(id)object
{
id lengthObject = [object valueForKey:@"length"];
unsigned length = [lengthObject isKindOfClass:[NSNumber class]] ? [count unsignedIntValue] : 0;
arrayOfSteps = [[NSArray alloc] initWithCapacity:length];
unsigned i;
for (i = 0; i < length; ++i) {
id element = [object webScriptValueAtIndex:i];
if (element)
[arrayOfSteps addObject:element];
}
NSLog(@"arrayOfSteps filled with %u elements !", [arrayOfSteps count]);
}

Hope that helps.
