首先，我建议使用UITableView，这样可以保持较低的内存使用率。我在项目中成功使用的方法如下：

1。列表项

复制单元格的内容，我的意思是如果你有这样的5项：

| 1 | 2 | 3 | 4 | 5 |

你应该在表的末尾添加相同的（在具有可重用引擎的表视图中，这不是什么大不了的事），看起来像这样： / p>

| 1 | 2 | 3 | 4 | 5 | 1 | 2 | 3 | 4 | 5 |

2。使用以下内容修改scrollViewDidScroll：

   - （void）scrollViewDidScroll：（UIScrollView *）scrollView 
 {
 if（scrollView == _yourScrollView）{
 CGFloat currentOffsetX = scrollView.contentOffset.x; 
 CGFloat currentOffSetY = scrollView.contentOffset.y; 
 CGFloat contentHeight = scrollView.contentSize.height; 

 if（currentOffSetY<（contentHeight / 6.0f））{
 scrollView.contentOffset = CGPointMake（currentOffsetX，（currentOffSetY +（contentHeight / 2）））; 
} 
 if（currentOffSetY>（（contentHeight * 4）/ 6.0f））{
 scrollView.contentOffset = CGPointMake（currentOffsetX，（currentOffSetY  - （contentHeight / 2）））; 
} 
} 
} 
 

上面的代码移动滚动如果你几乎达到滚动的最后一个位置在顶部;或者，如果你几乎在顶部，将你移到底部...

3。就是这样。

I have a scrollview with 5 image views of width 88.

I want the scrollview to scroll to each image view (Not Paging)

and

I want to make an infinite scrollview in iPhone which means the when it scroll to last item it will display a first item next to it..

I have been trying by offset but it stops when move it by offset and also I have used apple street scroller which does not allow me to stop each element in center(just like Picker view)..

First of all, I recommend to use a UITableView so you can maintain the memory usage low. An approach that I had used successfully in a project is the following:

1. List item

Duplicate the content of your cells, I mean if you have 5 items in this way:

| 1 | 2 | 3 | 4 | 5 |

You should add the same (In a table view with reusable engine that's not a big deal) at the end of the table in order to look like this:

| 1 | 2 | 3 | 4 | 5 | 1 | 2 | 3 | 4 | 5 |

2. modify the scrollViewDidScroll with the following:

-(void)scrollViewDidScroll:(UIScrollView *)scrollView
{
    if (scrollView == _yourScrollView) {
        CGFloat currentOffsetX = scrollView.contentOffset.x;
        CGFloat currentOffSetY = scrollView.contentOffset.y;
        CGFloat contentHeight = scrollView.contentSize.height;

        if (currentOffSetY < (contentHeight / 6.0f)) {
            scrollView.contentOffset = CGPointMake(currentOffsetX,(currentOffSetY + (contentHeight/2)));
        }
        if (currentOffSetY > ((contentHeight * 4)/ 6.0f)) {
            scrollView.contentOffset = CGPointMake(currentOffsetX,(currentOffSetY - (contentHeight/2)));
        }
    }
}

The code above move the scroll position at top if you almost reach the final of the scrolling; Or if you are almost on the top, moves you to the bottom...

3. That's it.
