ios - iPhone, tapGesture 在一个view 改变之后就不工作了？

Question

第一张图中，tap gesture是可以在红框框中点击的。

然后我删除了购物车中的item，改变了白色tablview的frame，这个时候将blur view 多暴露的一块。

第二张图，下面的小红框框，blur view 多暴露的这一块，tap 就失效了。

我尝试过每次改变tableview的frame之后，再次添加gesture，但是无效。

self.blurEffectView.frame = CGRectMake(0, 0, self.view.frame.size.width, rootView.frame.size.height - cartViewHeight);
       // let blur view full of screen.
        self.tapGesture = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tapGestureHandle:)];
        [self.blurEffectView addGestureRecognizer:self.tapGesture];

Answer 1

May be obscured, or provide as many codes as possible

Answer 2

In order to better help you solve the problem, it is recommended that you provide a demo

Answer 3

Is it effective to remove first and then add it?

Answer 4

Does this gesture conflict with tableview’s didselect? You have disabled didselect and try again
