add an Action Button in the currentView

I'm beginner in objective-c and i don't find a solution on internet about my problem.

I'm trying to add a new action to a Button and it doesn't work. Indeed i have more views in all the Views excepted the first View, i can't add this action to a button. I work with Interface Builder to design my graphical View.

And if i want to add action to a button of the 2,3rd .. View by linking the button to ViewController.h, i can't It's the same if i want to link the button to UIViewController.h, I have an error message which tell: Could not insert new action connection: No @implementation found for the class "UIViewController"

i want to do that for example, if a user click on this button i will change the background color of the current View.

Another Question:

I don't know how to know what the current view is, for example if i want to change the color of the current view what i have to do ?

Thanks for you help.

Answer : Make sure you have your ViewController.m file in the project and that it has block starting with @implementation and ending with @end.

I don't know how to know what the current view is, for example if i want to change the color of the current view what i have to do ?

Answer : [self.view setBackgroundColor:[UIColor redColor]];
