iOS：向容器视图添加UITapGestureRecognizer拦截UICollectionView的didSelectItemAtIndexPath方法

Question

我在我的ViewController中向我的主UITapGestureRecognizer添加了Content View，以便在点按内容视图时关闭我的键盘。

问题是我的内容视图中有UICollectionView，并设置UITapGestureRecognizer拦截了UICollectionView的点按。

如何允许我的UICollectionView点按，以便didSelectItemAtIndexPath方法再次触发？

func setupGestureRecognizer() {
    let dismissKeyboardTap = UITapGestureRecognizer(target: self, action: "dismissKeyboard")
    contentView.addGestureRecognizer(dismissKeyboardTap)
}

func dismissKeyboard() {
    contentView.endEditing(true)
}

Answer 1

解决此问题的方法是在您的.cancelsTouchesInView = false中添加 UITapGestureRecognizer 。

这允许其他视图中的触摸通过，例如UITableViewCell触摸。

func setupGestureRecognizer() {
    let dismissKeyboardTap = UITapGestureRecognizer(target: self, action: "dismissKeyboard")
    dismissKeyboardTap.cancelsTouchesInView = false
    contentView.addGestureRecognizer(dismissKeyboardTap)
}

func dismissKeyboard() {
    contentView.endEditing(true)
}

Answer 2

试试这个

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    [self.view endEditing:YES];
}  

并删除你的tapGesture。
