Ios 点击UICRollView按钮重新加载UICRollView

让我先解释一下我的项目。我在我的

SQLIte

DB表中有一些名为“note”的数据。 在“note”表中，我有以下字段：

id

，

noteToken

，

note

我在这里做的是从该表中加载

NSMUtableArray

中的所有

note

。并根据该

数组

内容编号创建

ui按钮

，并将这些按钮作为

子视图

添加到

ui视图中。按钮的数量和滚动视图的宽度根据该数组的内容数量自动生成。现在，当有人点击其中一个按钮时，它会将他带到下一个
viewController
，并向他显示该
viewController
中相应的注释详细信息

我对另一个
NSMUtableArray
做了同样的事情，但这一次它读取了“note”表中的所有
id
。它在相同的
UIScrollView
中同样生成新的删除按钮。但是如果有人点击这些删除按钮，它将从
SQLIte
DB的表“note”中删除特定的注释并重新加载
UIScrollView。除了重新加载
UIScrollView
零件外，所有操作都已完成。这就是我想要的。我尝试了所有存在的解决方案，但不知道为什么它不起作用。

这是我的密码：
