For some reason [self performSelector:@selector(myMethod:) withObject:nil afterDelay:5]; Does not work but [self performSelector:@selector(myMethod) withObject:nil afterDelay:5]; Does! EDIT: Declared in the implementation of a class but not the int...

I am currently doing a lot of data wrangling. I ingest a lloonngg NSData byte streams and then parse that data. The parsing is trivial. However, I have to simulate consumption of the data as I parse via not particularly elegant bookkeeping. Here is what a typical method looks like in the category of NData I have implemented: // Grab a l...
Ok, I have an IBAction that syncs with iCal and is also triggered by KVO of the 'name' property in my CD Model, so that when the property changes the Action is triggered. What happens is that once the IBAction reaches the end it skips to the KVO declaration which then triggers the Action again and again and again, this is where the loop ...

Normally I'd do something like this: [window makeKeyAndOrderFront:self]; [[window animator] setAlphaValue:1.0]; and to fade out: [[window an...
