Question

So, I want to create a reusable widget as a xib and subview that can appear on a set amount of specific screens. This widget will have three buttons, each with an Action.

I want to be able to handle these actions on multiple viewcontrollers.

So say ViewControllerA, ViewControllerD, and ViewControllerF can handle the three button events, each in their own way.

I’ve created the nib file. How do I import it into the specific viewcontrollers, and then how do I wire up those events?

EDIT: I know that I could potentially get outlets set up via a viewcontroller, but Apple states that UIViewController is for full-screen views only, and my widget is only taking up a small portion of the screen.

You have done correctly. And one thing is, In iOS it’s not widget.It’s a UIView.

(Sorry there may be any typo in my code.I have written myself in StackOverflow)

Follow Below Steps to finish it..

1) After you have created the xib for the view, then you need to have a UIView subclass files.. For example your xib name likes this CustomView.xib means then create a files like this CustomView.m and CustomView.h

2) In your CustomView.xib , You need to set the fileOwner as your CustomView.h.

3) In your CustomView.m file, there will be a method like initWithFrame: In that method you need to load your xib file like this

NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"CustomView" owner:self options:0];
UIView *currentView = [topLevelObjects objectAtIndex:0];
[self addSubView:currentView];

4) Almost over. In any of your view controller, you can use this xib like

CustomView *newSubView = [[CustomView alloc]initWithFrame:CGRectMake(0,0,55,67)];
[self.view addSubView:newSubView];

That’s it.. Go on..
