Answer 1

-(void)scrollViewDidScroll:(UIScrollView *)ScrollView 
{ 
int scrollPositionX = callerScrollView.contentOffset.x; 
if (callerScrollView == tbl_ProductView) return; 
for (UITableViewCell *cell in tbl_ProductView.visibleCells) { 
UIScrollView cellScrollView = (UIScrollView)[cell viewWithTag:100]; 
if (callerScrollView == cellScrollView) continue; 
NSInteger indexPath = callerScrollView.tag; 
//NSLog(@"IndexPath Of Cell: %ld",(long)indexPath); 
cellScrollView.contentOffset = CGPointMake(scrollPositionX, 0); 
} 
//ScollPage Position 
static NSInteger previousPage = 0; 
CGFloat pageWidth = callerScrollView.frame.size.width; 
float fractionalPage = callerScrollView.contentOffset.x/pageWidth; 
NSInteger page = lround(fractionalPage); 
    if (previousPage != page) 
{ 
    previousPage = page; 
    NSLog(@"Scrolling Page: %li",(long)page); 
}

Sie jeden subview, indem Sie diese auf UIScrollView bekommen können.

for(UIView * subView in scrollView.subviews) 
{ 
    // Here You can Get all subViews of your myScrollView. 
}
