scroll-paging

I have a UICollectionView with 6 pages, and paging enabled, and a UIPageControl. What I want is, when I came to the last page, if I drag to right, UICollectionView reloads from first page seamlessly. - (void)scrollViewDidEndDecelerating:(UIScrollView *)sender { // The key is repositioning without animation if (collectionView.contentOffset.x == 0) { // user is scrolling to the left from image 1 to image 10. // reposition offset to show image 10 that is on the right in the scroll view [collectionView scrollRectToVisible:CGRectMake(collectionView.frame.size.width*(pageControl.currentPage-1),0

OBSERVATIONS I've discovered some "weird" things about how UITableViews / UIScrollViews scroll in Objective-C for iOS after you've lifted your finger: A scroll view's "velocity" (as in scrollViewWillEndDragging:withVelocity:targetContentOffset: ) is not based in time but rather based in "render" or "frame refresh" or the like; i.e., a "velocity" of 3.0 means that the scroll view will scroll 3.0 points before the next refresh, at which point it will scroll yet another 3.0 points if the "velocity" is still 3.0. (in contrast to an absolute time-based velocity) "Refreshes" occur approx. 950 times

I'm wanting to add a UIScrollView with paging to go through different views from my existing view controller which is the root view of my app. I also have tab bar and navigation bar controllers along with it. Can I add a scroll view to this view controller to accomplish what I'm wanting, and if so, can someone point me in the right direction on how to go about it? Here is my view controller. #import "KFBViewController.h" #import "ListViewController.h" #import "ActionAlertsViewController.h" #import "MarketUpdatesViewController.h" #import "AgStoriesViewController.h" #import

I have a scroll view that is the width of the screen but only about 70 pixels high. It contains many 50 x 50 icons (with space around them) that I want the user to be able to choose from. But I always want the scroll view to behave in a paged manner, always stopping with an icon in the exact center. If the icons were the width of the screen this wouldn't be a problem because the UIScrollView's paging would take care of it. But because my little icons are much less than the content size, it doesn't work. I've seen this behavior before in an app call AllRecipes. I just don't know how to do it.

How can I force a UIScrollView in which paging and scrolling are on to only move vertically or horizontally at a given moment? My understanding is that the directionalLockEnabled property should achieve this, but a diagonal swipe still causes the view to scroll diagonally instead of restricting motion to a single axis. Edit: to be clearer, I'd like to allow the user to scroll horizontally OR vertically, but not both simultaneously. Andrey Tarantsov You're in a very tough situation, I must say. Note that you need to use a UIScrollView with pagingEnabled=YES to switch between pages, but you need
