iOS Can't initialize CGPoint and CGFloat inside a UIView

[CMT]

Probably the error is silly, but I can't make this work.

I've subclassed an UIView and added two fields: 1 CGPoint and 1 CGFloat. I know this is not all MVC compliant, but I just don't want to create a model object for this.

The problem is that when I want to use them in drawRect:, both are null.

No errors or messages in the console.

@interface DotView : UIView {

    CGPoint center;
    CGFloat radius;
}

@end


@implementation DotView

- (id)initWithFrame:(CGRect)frame {
    if ((self = [super initWithFrame:frame])) {
        
        center = CGPointMake(50.0, 50.0);
        radius = 10.0;
    }
    return self;
}

@end

Thanks!

Did you add the framework?

Yes, the framework is there.

Is awakeFromNib being called instead?

- (void)awakeFromNib
{
        printf("here I am\n");
}

Edit:

If this works instead, the explanation is here: http://developer.apple.com/mac/libr....html#//apple_ref/doc/uid/TP40002978-CH7-SW21

Start reading at "Initializing View Instances Created in Interface Builder"

Thank you a lot, solved the problem.

In fact I was starting to think that IB could be involved in this, but concluded that inside an init method it should work (until now).

I vaguely remembered beating my head against my desk a year or two ago dealing with the same issue.

I can never remember which init/awake/willshow gets called first. So I just add a Boolean to my instance variables; if I find that it's 0 in any call to drawRect (the first), init my graphic rects/points/colors/whatevers or call my initializer methods there, then set the Boolean to true. Works even if I keep switching view instantiation back and forth between programatic and nib during development/reuse.
