I am relatively new to IPhone coding, although I have reached the point of working on a genuine (hopefully) saleable app.
But one thing that is still mysterious is the responder chain. All the books give passing reference to it, but I have not found one...

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch* touch = [touches anyObject]; NSUInteger numTaps = [touch tapCount]; if (numTaps < 2) { [self.nextResponder touchesBegan...

I would add a quick NSLog in your forwarding code to check what your nextResponder really... .

I have a WPF application that occasionally crashes, and say "not responding". Is there a way to detect if the program is not responding? And if so, restart the WPF application?

Because this is a temporary fix while you debug the app, one possibility is to cheat and use a bootstrapper/startup app whose sole job is to monitor the problematic app .

Let me summarize that shortly: A "First Responder" in a NibFile is an Object, which represents the UI control element that has the user's focus. So if the user klicks on an UI control, the Nib sets that clicked UI control as First Responder. In my app...

Am I right with my understanding, that an UIApplication object, UIWindow object, UIView object or any UIView subclass is an "Responder object"?

Lately I have been trying out Rails, and I came to love the respond_to.
Is it possible to do something like this in PHP?, responding to different types of requests. So it is easy to implement an alternate way even if javascript is disabled.
