Thanks Marco,
It was even slightly more straightforward than your suggestion:
I bound the NSStepper and textField to plugIn.argumentCount
Had:
@property NSUInteger argumentCount;
and a matching ivar
Added your method (I'd like to know what docs/example that was in -
can't find it anywhere. It is much cleaner than my way of doing it!).
I guess that method over-rides the one generated with @synthesize
argumentCount; so no other methods needed - the binding takes care of
the rest. When the bound value changes the accessor seems to be
observing it so, it just works.
Thanks very much.
Regards, Ian

I have subclassed QCPlugInViewController to handle the IBAction I
called amendStrings that adds, removes in increments in response to
NSStepper and when the textfield is manually edited.
The subclass of QCPlugInViewController looks like this:
@interface UITestPlugInViewController : QCPlugInViewController
{
int currentStringCount;
int previousStringCount;
int diff;
BOOL raisedFlag;
BOOL loweredFlag;
BOOL firstCall;
}
- (IBAction) amendStrings:(id)sender;
@end
I am wondering: do I need to subclass QCPlugInViewController at all?
Should the ivars (the ints) be dynamic properties of qcplugin? and
are therefore 'serialised' when the patch is copied?
You should not have to create an QCPluginViewController subclass.
You also don't really need to store all the view controllers in an
array unless you really need them. And you probably won't. Just take
the NIB file provided by the Xcode template (assuming you started
your patch using the right Xcode template) and hook up all the
bindings just the way you did. Then, implement a custom -
setNoOfStrings: method which saves the new count into the ivar and
then calls the following method (I didn't write that one myself, it
probably comes from the docs...):
- (void) setArgumentCount:(NSUInteger)newCount {
NSUInteger i, currentCount = self.argumentCount;
/* Update argument input ports */
if(newCount > currentCount) {
for(i = currentCount; i < newCount; ++i)
[self addInputPortWithType:QCPortTypeString
forKey:[NSString
stringWithFormat:@"argument_%i", i]
withAttributes:[NSDictionary dictionaryWithObject:[NSString
stringWithFormat:@"Argument #%i", i + 1]
forKey:QCPortAttributeNameKey]];
}
else if(newCount < currentCount) {
for(i = newCount; i < currentCount; ++i)
[self removeInputPortForKey:[NSString stringWithFormat:@"argument_
%i", i]];
}
/* Save new argument count */
argumentCount = newCount;
}
This should get you going. Please forgive me if this isn't
everything you need to get going, I didn't read all your code just
now : )
Marco
