如何将手势从 UITextView 传递到 UICollectionViewCell [英] How to pass gestures from UITextView to UICollectionViewCell

问题描述

我有一个带有 UICollectionViewCells 的水平滚动 UICollectionView，其中包含一个 UITextView.有没有办法将 textview 上的手势传递给单元格，以便调用 didSelectItemAtIndexPath?.我尝试将 UITextView 子类化并将 touchesbegin/end 传递给单元格，但这没有用.

I have a horizontal scrolling UICollectionView with UICollectionViewCells that contain a UITextView. Is there any way to pass gestures on the textview to the cells, so that didSelectItemAtIndexPath gets called?. I tried it with subclassing UITextView and passing touchesbegin/end to the cell, but that didn't worked.

推荐答案

您可以使视图非交互式，这将导致触摸通过:

You can make the view non-interactive, which will cause touches to get passed through:

textView.userInteractionEnabled = NO;

如果你需要它是互动的，你可以试试这个:

If you need it to be interactive, you can try this:

textView.editable = NO;
UITapGestureRecognizer* tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapped)];
[textView addGestureRecognizer:tap];

... 然后将此函数添加到您的 UICollectionViewCell 子类:

... and then add this function to your UICollectionViewCell subclass:

-(void) tapped {
    UICollectionView *collectionView = (UICollectionView*)self.superview;
    NSIndexPath *indexPath = [collectionView indexPathForCell:self];
   [collectionView.delegate collectionView:collectionView didSelectItemAtIndexPath:indexPath];
}

我还没有测试过...
