In an application that I'm writing I have a UIWebview up top and some UITextFields at the bottom that I want the user to be able to type in depending on what's in the webview. But when they touch the Text Field and the keyboard pops up, the user loses the ability to manipulate the web page to see different parts.
Is there a way to keep the keyboard up and still be able to manipulate the UIWebView?
No I believe the Keyboard is modal so you can't access the form underneath it.
You can respond to the
- (void)keyboardWillShow:(NSNotification*)aNotification;
- (void)keyboardWillHidde:(NSNotification*)aNotification;
notifications and scroll the View up or down when the keyboard is shown...

Instagram has a really cool interaction where you can tap-and-hold, aka longPress, on an image and an interactive pop-up appears. Once it appears you can drag your finger to one of the action buttons and removing your finger applies the action and closes the pop-up.

How can I achieve this.
I am trying to write an app that uses a custom keyboard. How can I write code that prevents the iPhone keyboard from popping up. I have seen a custom keyboard that enters text in other iPhone applications, so I know that it is possible.
You're looking for the inputView property that's present on every view (inherited from UIResponder).
I've seen a couple of apps that show a transparent view on top of the current ui while the keyboard is present and if clicked it hides the keyboard. I looked around the web and couldnt find a solution for this problem.
Simply add a UIButton, custom type, the size of your screen and add it to your view when your text field (or other entry) takes focus. Make sure your edit view is brought to the front of its superview at the point you add the button (to ensure the edit view still responds to touch).
Add a target to the button which dismisses the keyboard ([myTextfield resignFirstResponder]) and removes the button.
Also make sure to remove the button when the textField dismisses normally.
I'm writing an app based around a calculator-like UI. On an iPad, I'd like the number UIButtons on my calculator UI to respond to the numbers on the external keyboard. I have no text input anywhere in the app, and I'd never want an on-screen keyboard to appear. How do I get my UIButtons to respond to specific key presses as if they'd been touched?
I'd say create a hidden UITextField with the delegate set, make it become the first responder upon viewDidLoad. The keyboard won't appear when a bluetooth keyboard is connected as far as I know, then just check what characters are typed in the shouldChangecharactersInRange and activate the right buttons accordingly.
EDIT: a quick example I just made, https://github.com/benjaminq42/buttonTest , if you wish to have a highlight animation of some sorts you need to create a custom UIButton class. You can use 'setHighlighted' but that 'sticks'.
In the iPhone Objective-C app, I want to pop-up a window (which is smaller than the main view, and the app does not stop running) when a button is tapped, with textField for the user to input text, and dismiss it when it is done.
This is widely used but I really cannot google the relevant content out.
What view should I use to connect it with the button? AlertView (which seems you cannot add dialogue in), ModalView?
Are there relevant info somewhere?
Thanks.
Make the popup it's own, full-sized window. Put a UIImageView in behind your popup screen, and duplicate the results of the normal window. That way, it will look like a popup window, but it still has the proper animation speed and everything. If you do it as a real popup, the game itself will slow down and look jumpy.
You can create any view and use UIViewController's presentModalViewController: to display a modal view controller (and even animate it).
