Question

I have a custom UIView (MyCustomUIView) which is built using Interface Builder. I’d like to place this custom view in MyViewController‘s view, which is also designed using IB. I’ve placed an UIView as a subview in MyViewController‘s XIB and set it’s class to MyCustomUIView. The problem is, when I run the code, only a blank view appears. (When I instantiate MyCustomUIView in code, it displays well.)

I’m only overriding the initWithFrame: method the following way in MyCustomUIView.m:

- (id)initWithFrame:(CGRect)frame
{
    [[NSBundle mainBundle] loadNibNamed:@"MyCustomUIView" owner:self options:nil];
    self = self.view;
    return self;
}

What should I do to make the view load properly? How should initWithCoder: look like?

Answer 1

You are correct. IB uses initWithCoder. initWithCoder should look very similar to your other init methods:

- (id)initWithCoder:(NSCoder *)aDecoder {
    self = [super initWithCoder:aDecoder];
    if (self) {
        // CUSTOM INITIALIZATION HERE
    }
    return self;
}

Once you assign your class within IB, you won’t need to instantiate it from the bundle unless I’m misunderstanding your intention.
