Access properties with self returns always "null"

Question

Hi,

i´ve got a custom-UIScrollView-class. On the "- (id)initWithFrame:(CGRect)frame"-function i set different properties, but when i want to access a property like "self.zoomScale", it´s always "null".

Here´s my definition:

"@interface MyScrollView : UIScrollView <UIScrollViewDelegate> {.."

And here´s the .m-file:

...
- (id)initWithFrame:(CGRect)frame {
    if ((self = [super initWithFrame:frame])) {

   //setup etc.
   [self setMaximumZoomScale:2.0f];
   [self setMinimumZoomScale:1.0f];
   //......

}

Any ideas on that? Would be great to know.. Thanks for your time.
