Question

我在UICollectionView中有一系列UICollectionViewCell UICollectionViewFlowLayout。

每个单元格包含一个UIImageView，取决于indexPath大于单元格本身。单元格不会剪切其内容，因此您始终可以看到整个图像。

但我不能在细胞框架外进行触摸，而是在图像内部进行正常触摸并触发细胞选择。

我尝试覆盖hitTest:withEvent的方法pointInside:withEvent和UICollectionViewCell，但它没有任何变化。

- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event {

    if (CGRectContainsPoint(self.imageView.frame, point)) {
        NSLog(@"Contains: %d", cellIndex);
        return self;
    }
    NSLog(@"Doesn't contain: %d", cellIndex);

    return [super hitTest:point withEvent:event];
}


- (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event {

    if (CGRectContainsPoint(self.imageView.frame, point)) {
        NSLog(@"Inside: %d", cellIndex);
        return YES;
    }

    NSLog(@"Outside: %d", cellIndex);
    return NO;
}

当我在屏幕上显示集合视图的前3个元素时，我会点击第三个元素（在它的单元格框架之外，但在UIImageView内部），这就是它的痕迹：

点击UICollectionViewCell外部
