在 UICollectionView 中实现按钮点击 [英] Achieve button click in UICollectionView

问题描述

有没有办法从 UICollectionViewCell 中的按钮获取按钮单击事件?我用笔尖填充集合视图，单元格有按钮，但它的动作没有被调用.我认为问题在于被调用的代表.我该如何解决这个问题?

Is there a way I can get the button click event from a button inside a UICollectionViewCell? I used a nib to populate the collection view, the cell has the button but its action is not getting called. I think the problem is with the delegate being called. How can I fix this?

我是如何创建的:

1. 添加了一个空笔尖，创建了一个集合视图单元格
2. 添加了一个 .h 和 .m 文件，并将单元格 nib 的文件所有者作为创建的类<​​/li>
3. 在课堂上写了一个动作.
4. 将按钮连接到操作

有没有办法让我采取行动?我做错了什么?

Is there a way I can get the action? What am I doing wrong?

推荐答案

像这样添加按钮动作:

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {

    CollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"CellId" forIndexPath:[indexPath row]]; 

    [[cell myButton] addTarget:self action:@selector(myClickEvent:event:) forControlEvents:UIControlEventTouchUpInside];

    return cell;

}


- (IBAction)myClickEvent:(id)sender event:(id)event {

    NSSet *touches = [event allTouches];

    UITouch *touch = [touches anyObject];

    CGPoint currentTouchPosition = [touch locationInView:_myCollectionArray];

    NSIndexPath *indexPath = [_myCollectionArray indexPathForItemAtPoint: currentTouchPosition];

}
