我从相同屏幕上的两个不同按钮执行segue到相同的视图控制器，因此使用相同的segue标识符 . 说按钮是B1和B2 . 因此，当我从B1执行segue的segue时，我希望目标视图控制器禁用用户交互，但是当我从B2中删除时，我希望目标视图控制器可以被点击并且其文本字段是可编辑的 . 请帮我实现它 . 在这里......考虑B2被部分压缩，B1被认为是toplbl，请帮我用这个代码实现它，所以建议我在这里做的改变 .

let i = self.getIndex(sender.tag)

使用prepareForSegue:方法 . iOS会将按钮作为
sender参数传递给您，并且还可以将目标视图控制器作为UIStoryboardSegue参数的一部分提供 .检查
sender以查看它是B1还是B2. 当发件人是B2时，禁用segue目标控制器中的用户交互：您可以使用一个密钥，并在调用segue之前更改该密钥的值 . 并根据该键改变了按钮/文本字段等的交互 . 这是一种解决方法，也许你会得到比这更好的答案 .
我发现了一个简单的方法 . 我们可以为partialpressed按钮声明一个全局或局部布尔变量，我们可以将其设置为true，对于toplbl按钮，我们可以将其设置为false，然后我们有两种方法来禁用用户交互：
如果bool是全局的：转到目标视图控制器并且内部视图加载检查是否bool == false然后设置self.view.userinteraction = false
如果bool是局部变量：在初始视图控制器中转到prpareforsegue并检查是否bool == false然后设置segue.destinationviewcontroller.view.userinteraction = false
