Question

-(void)layoutScrollImages 
{ 
UIImageView *view = nil; 
NSArray *subviews = [scrollView1 subviews]; 
CGFloat curXLoc = 0; 
for (view in subviews) 
{if ([view isKindOfClass:[UIImageView class]] && view.tag > 0) 
{ 
CGRect frame = view.frame; 
frame.origin = CGPointMake(curXLoc, 0); 
view.frame = frame; 
curXLoc += (kScrollObjWidth); 
} 
} 
    [scrollView1 setContentSize:CGSizeMake((kNumImages * kScrollObjWidth), [scrollView1 bounds].size.height)]; 
} 

-(void)viewDidLoad 
{ 
self.view.backgroundColor = [UIColor clearColor]; 

    [scrollView1 setBackgroundColor:[UIColor whiteColor]]; 
[scrollView1 setCanCancelContentTouches:NO]; 
scrollView1.indicatorStyle = UIScrollViewIndicatorStyleWhite; 

scrollView1.clipsToBounds = YES; 
scrollView1.scrollEnabled = YES; 
scrollView1.pagingEnabled = YES; 
NSUInteger i; 
for (i = 1; i <= kNumImages; i++) 
{ 
NSString *imageName = [NSString stringWithFormat:@"snap%d.jpg", i]; 
UIImage *image = [UIImage imageNamed:imageName]; 

UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; 
CGRect rect = imageView.frame; 
rect.size.height = kScrollObjHeight; 
rect.size.width = kScrollObjWidth; 
    imageView.frame = rect;imageView.tag = i; 
[scrollView1 addSubview:imageView]; 
[imageView release]; 
[self layoutScrollImages]; 
} 
[super viewDidLoad]; 
} 

Answer 1

добавить UIScrollViewDelegate к интерфейсу, а затем сделать вашу задачу в

scrollViewWillBeginDragging or `scrollViewDidEndDragging` 

- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView // called on start of dragging (may require some time and or distance to move) 
{ 
    //add your code here 

} 

теперь этот метод будет вызываться всякий раз, когда вы перетащите Scrollview
