How to get dimensions of a custom UIView added via storyboard in initWithCoder:?

Question

I have a custom UIView subclass that adds a subview programatically during initialisation. I'm wanting this subview to be the same width as the custom UIView.

My code works fine if I programatically add the custom UIView. However, when the UIView is initialised via the StoryBoard, I cannot obtain the custom UIView's width.

// Init programatically
- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        NSLog (@"view: %f", self.frame.size.width);   //WILL return width
        NSLog (@"view: %f", self.bounds.size.width);  //WILL return width
    }
    return self;
}

// Init from storyboard
- (id)initWithCoder:(NSCoder *)aDecoder {
    self = [super initWithCoder:aDecoder];
    if (self) {

        NSLog (@"view: %f", self.frame.size.width);   //Returns 0
        NSLog (@"view: %f", self.bounds.size.width);  //Returns 0
    }
    return self;
}

When initWithCoder: is run by StoryBoard, the UIView's frame and bounds are all returned as 0. Is there any way of accessing the UIView's dimensions within initWithCoder?? Or, at least access the dimensions before drawRect: is called?

Thanks.

Answer 1

Rather than set the subviews dimensions in the init function, set it relative to the custom view in the layoutSubviews method of the custom view. Doing it here will mean that the width of the subview will also always change to match the width of the custom view even if you change the dimensions of the custom view at any point after initialisation.

You can re-use your standard initWithFrame call.

- (id)initWithCoder:(NSCoder *)aDecoder 
{
    self = [super initWithCoder:aDecoder];
    if (self) {

        [self initWithFrame:[self frame]];

        NSLog (@"view: %f", self.frame.size.width);   
        NSLog (@"view: %f", self.bounds.size.width); 
    }
    return self;
}
