Zooming on UIScrollView with paging enabled and multiple images

I Have a UIScrollview with a UIImageView inside where I scroll from an image to another.

I used the TapToZoom Apple sample code to implement the zoom but whenever I zoom the scrollview starts from the begining rather than the active image.

Here's a piece of my code :

Init and populate the imageview :

table = [[NSMutableArray alloc] initWithCapacity:7];
for(int count = 1; count <= 7; count++)
{
    NSString *fileName = [NSString stringWithFormat:@"image%d.jpg", count];
    UIImage  *image    = [UIImage imageNamed:fileName];
    [table addObject:image];
    if (image == nil) {
        break;
    }
    imageView = [[UIImageView alloc] initWithImage:image];
    imageView.userInteractionEnabled = YES;
    imageView.multipleTouchEnabled = YES;

Implement Tap Gesture :

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];
    UITapGestureRecognizer *doubleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleDoubleTap:)];

The handle开发者_运维问答DoubleTap method zooms to the center of the the imageView and brings the scrollview to the begigining of the paging.

I searched a lot about this, but was unable to find a way to zoom on the actual displayed image.

Thanks in advance :)
