问题 I'm trying to use the new auto layout capability of iOS 6 on a custom UITableViewCell which has been implemented programmatically. I added the addConstraint calls, and it works properly at first-- until I scroll. When I come back to the cell after scrolling the layout is trashed. By trashed I mean the margins between fields are all wrong (too large, well beyond the size of the cell). I'm speculating this has something to do with the dequeueReusableCellWithIdentifier method leaving me with a

问题 I have a view that is shown under a navigation controller. The view contains one subview at the top portion and a table view at the bottom. The table might have rows that extend beyond the visible height based on data. When I have rows that are below the last visible row, if I scroll the view up, it bounces back, it does not stay there. Is there a way to make it stay? I tried making the parent view a scroll view and that did not help. My view is from a XIB. 回答1: Sounds like the size of your

At the top of the page I got So I would like the arrow-up div to visible(show("slow")) when not on top of the page. var tmp = $(window).height(); Tmp is used to get the viewport height...
