I'm creating sibling of UITextField, but with UIDatePicker instead of a keyboard. I want multiple such controls to play nicely with each other and also standard UITextField (i.e. swap keyboard for date picker when my control is activated, and hide date picker when a text field is activated). One thing that confuses me is handling of f...
I have a custom TableView cell that contains a TextField and I want it to become the first responder as soon as the view is shown but [textcell.textfield becomeFirstResponder] does not work. I know it's because it's a custom cell in another class and I even tried it there and it didn't work. Anyone know how to pull this off? Thanks... ...
I have a UIView subclass (CustomView for purposes of this question) that has its own handling of all touches events (Began, Moved, Ended, Cancelled). I also have a UIButton that is a sibling of CustomView that overlaps it. For example, my view hierarchy looks like this: UIView (Controller's view) CustomView with frame (0, 0, 300, 300...

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 yet that describes how to modify that chain. Another curiosity is that, when the F...
Hello, I have an NSArrayController whose content is the "servers" property of my AppDelegate.

I'd like to change the background image of a UITextField when it becomes the firstResponder to show the user that it has focus, similar to the :active or :focus pseudo-classes in CSS. I'm guessing that I may need to do this programmatically; so any help is greatly appreciated. -Giles ...
I'm working on a Cocoa programming exercise, and I need to be able to determine which of two NSTextView objects is currently being edited. I think it's something to do with finding the first responder and checking to see if it's equal to one text field or another, but I can't quite get it to work. Any help would be appreciated. ...

I tried doing it in viewWillAppear like below without any luck: - (void)viewWillAppear:(BOOL)animated { [product...
I've been having some issues with calling -becomeFirstResponder on a UITextField contained with a view controller that is presented modally. I call this method in the modal view controller's -viewDidLoad method so that the keyboard is immediately displayed. What I expected is for both the keyboard and the modal view controller to animate...

I am confused about the iPhone responder chain. Specifically, in the iPhone event handling guide http://developer.apple.com/iPhone/library/documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/EventHandling/EventHandling.html, we have the following: The first responder is the responder object in an application (usually a UIView obje...

When I show the menu I need to wait for the user to select an item before the menu fades away but if the click anywhere on the screen (not on the menu bar) the menu will still fade out.
