Finally, I got the application working with interactions. I credit http://zone12.co.uk/iCode/tut1.html for this information.

Step 1: Create a new Cocoa Touch Application.

Step 2: Pick the directory and name for your application.

Step 3: As per the current template, it doesn’t generate Interface Builder file for you. Create a new one after opening the Interface builder in parallel as shown below: (Choose Cocoa Touch - View)

Step 4: Design the screen as shown below. Use Placeholder text for your input box with the text shown in gray color.

Step 5: You have to save the file to associate with the project. (Save it in the same folder as the other files).

Step 6: It will prompt you to add this to the created project for deployment. Click the checkbox and click “Add”.

Step 7: Now Choose “File’s Owner” object and select “Object Identity” tab of the Inspector (Tools - Inspector).

Step 8: Now change the Class (which is NSObject) to ButtonClickAppDelegate.

Step 9: Create Outlets for Text Box & Label. Also create Actions for button as shown below after clicking this Object. Select UILabel and UITextField as the type for those new outlets.

Step 10: Connect this object to the outlets created. Choose connections tab on the Inspector. Drag each one and connect them as shown below:

Do the same for text box and select textBoxOutlet.

Step 11: Click on the Button. Select Button Connections inspector. Drag “Touch Up Inside” event to the object and Choose “buttonClicked”

Step 12: Click object. Choose File - Write Files… menu item. Overwrite the same Appdelegate file. Choose merge and finish the changes. They should look like the following:

Step 13: Save & Close the Interface Builder.

Step 14: Fix .m file with the following code for the new event handler.

- (IBAction)buttonPressed:(id)sender {

[labelOutlet setText:textBoxOutlet.text];

}
