页: 1 当用户浏览<编码>可调取的<<>可调用的<>密码>时,一定数额,然后释放他们的inger,而不是把 s发回顶,我想把50个点从顶点上排出来,实际上使屏幕顶和顶层之间的50个点相差。
目前,我已经实施了<条码> 编码>,但我不知道如何确定这些意见将回头去。
我尝试了以下几个方面,但并没有按要求开展工作。
- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate
{
// If scrolled over 100 points
if(-100 > (double)self.tableView.contentOffset.y) {
[self.tableView setContentOffset:CGPointMake(0, -50) animated:YES];
}
}
The code above causes a weird flicker, like the animations are both running concurrently, but I m unsure.
希望得到任何帮助。
UPDATE with more information
I m implementing "Pull down to refresh" functionality based upon this post: https://stackoverflow.com/a/6392145/120615
I ve added an extra UIView to the top of the UITableView and when you scroll the UITableView, the UIView moves down into view. When you release your finger from the screen, the UITableView scrolls back to the top hiding the new UIView I ve added.
我将做些什么? UITableView scrolls re to high but ends 100 points from the Superior (so I can show an activity index to theuser) and then after 2/3 seconds scrolls full to the Superior.
