使UICollectionView从右向左滚动？ [英] Make UICollectionView scroll right to left?

问题描述

UICollectionView在水平设置时滚动的自然方向是从左到右。有什么办法可以扭转这种情况吗？更简单的越好。

解决方案

我不知道你的意思 - 如果你设置滚动到水平，滚动同样好，左右。如果你想让它从右边开始，你可以使用这个方法：

  [self.collectionView scrollToItemAtIndexPath：[NSIndexPath indexPathForItem：self.theData.count  -  1 inSection：0] atScrollPosition：UICollectionViewScrollPositionRight animated：NO]; 
  

这假设你有1节，填充集合视图的数组称为数据。 p>

The natural direction for a UICollectionView to scroll when set horizontally is from left to right. Is there any way to reverse this? The simpler the better.

解决方案

I'm not sure exactly what you mean -- if you set the scrolling to horizontal, it scrolls equally well, left and right. If you want it to start it from the right side, you can use this method:

[self.collectionView scrollToItemAtIndexPath:[NSIndexPath indexPathForItem:self.theData.count - 1 inSection:0] atScrollPosition:UICollectionViewScrollPositionRight animated:NO];

This assumes that you have 1 section, and the array populating the collection view is called theData.
