When the user presses the button on the interface, I want the 1 button to be pressed automatically, how can I do that?
How do I create an hidden button? When I press the button, it creates a UIAlert and asks if I want to buy the product. And when I buy the product, the button will be visible?
If a button is hidden, it is not clickable. Instead, you may want to create a "clear" button. When you press the button, popup the UIAlert and make the button not clear.
When you click on a textfield in your iphone application, you will get the keyboard displayed. On that keyboard you will get a GO, DONE and SEARCH buttons. I need to get the On click event of these buttons.
What are they ?
become the delegate of the text field in question and you get sent
-(BOOL)textFieldShouldReturn:(UITextField *)textField
When the user taps the return button, whatever the label on the button is. (GO, SEARCH or DONE)

The alert displayed by a push/local notification has either one (OK) button, or two buttons - the left button is always "Close" and the right button is either "View" or a string (for action-loc-key) you supply in the dictionary for the alert key of your payload.
The functionality you require isn't available using the notification alerts directly. Maybe your app could "snooze" by default (i.e. when the close button is pressed - so unless the app is started the alarm plays again after 5 minutes). If the user presses the View button (maybe re-titled "Cancel Alarm") the app starts and the alarm is cancelled.

I have to import some XML data into my app.
Now I open a UIActionSheet and add as a subview a UIActivityIndicatorView. Initially I show a progress wheel and a button with 'Cancel'.
When the XML has been imported, I want to hide the progress wheel (this it's easy) and change the button into a 'Done' button, all in the same UIActionSheet.
What I'm doing now is closing the UIActionSheet with the option dismissWithClickedButtonIndex, but I don't like this way because it's the same as pressing 'Cancel', and then I show an UIAlertView displaying "All data has been imported".
Is this possible ?
You shouldn't be doing that, when it loads correctly just dismiss the ActionSheet. On the other hand if an error occurs then display an alert.
Think about the user who will use the app multiple times a day, a Done message each time will be a waste of time.
UPDATE
As i understand your goal is to use the ActionSheet just as a popup (with Cancel ability), if so, just call dismissWithClickedButtonIndex:animated: when your XML loading is done.
If its successful then just call the dismiss method, if its unsuccessful then call the dismiss and popup an alert
This is a bit of a hack but should work. Note that there is a good chance that this will result in your app not being accepted into the app store as you're messing around with the action sheet in ways Apple didn't intend.
Initially display the action sheet with both the 'Done' and 'Cancel' buttons. Before displaying the sheet hide the 'Done' button using its hidden property. To see how to access the 'Done' button see this question.
Then when you're hiding the UIActivityIndicatorView, also change the hidden property of both the 'Cancel' and 'Done' buttons, so that the 'Done' button becomes visible. If the 'Done' button appears in the wrong position move it by modifying its centre property.
