Ios “如何修复”；结构"；单击打开url时是否包含UIButton？

下面是结构中的代码。我已经添加了“url”，但不确定是否在所有（3）个位置正确添加到结构中。目标是将“URL”添加到结构中

下面是我用于您审阅的数组的代码。需要改变吗？或者我添加“url”的方式可以吗？这里的目标是将“URL”添加到数组中

下面是我想添加一个“

UIButton

”的detailVC的代码。在

ui按钮中，我将
main.storyboard
中的按钮添加到
DetailVC
。这里的目标是添加一个按钮以在单击时打开数组中的URL：我不确定在添加
UIButton
后如何正确编码

以下是
UIViewController
的代码。我不确定是否需要向
UIViewController
添加其他代码，因为我向DetailVC添加了一个按钮

我找到了在单击按钮时从数组中打开url的解决方案。我实施了以下措施：

@iAction func WatchButton已映射（uu发送方：SAButton）{
如果让url=url（字符串：self.state！.url）{
UIApplication.shared.open（url，选项：[：]，completionHandler:nil）
我找到了在单击按钮时从数组中打开url的解决方案。我实现了以下功能：

@iAction func WatchButton已映射（uu发送方：SAButton）{
如果让url=url（字符串：self.state！.url）{
UIApplication.shared.open（url，选项：[：]，completionHandler:nil）
请详细说明。哪个数组？哪个按钮？因此您想打开
状态
数组中最后一个对象的URL，对吗？在状态数组中如果您有10个状态，那么您想在视图控制器中创建10个按钮吗？然后当点击一个按钮时，您想在浏览器中打开相应的URL吗？数组中的每个项目都有一个URL作为参考与之关联。数组填充UITableView，其中每个单元格都有来自数组的状态名称。当从TableView中选择单元格时，它将移动到详细信息VC以查看有关状态的更多信息。在详细信息VC上，有2个标签、一个textview和一个按钮。该按钮是用户要单击以查看该单元格的url的按钮状态。请详细说明。哪个数组？哪个按钮？所以你想打开
