Question

i am trying to remake (mostly) the same sample example provided by apple which is called tapToZoom.

the difference is that i am using storyboard instead of a classic nib file as the example shows, i set an image inside the scrollView.

the problem is that the zoom don’t work e.g. here:

//set the initial zoom scale
 float minimumScale = [myScroll frame].size.width  / [myImage frame].size.width;

NSLog(@"%f",minimumScale);

[myScroll setMinimumZoomScale:minimumScale];
[myScroll setZoomScale:minimumScale];

NSLog()@"%f",[myScroll zoomScale];

the logs return 0.6 for the first one and 1.0 for the second which is supposed to be 0.6.
anyone got this problem before?

[EDIT]: the previous lines are into my viewDidLoad method.

Answer 1

I think you should implement

- (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView;

Try this delegate method.
