我有一个包含多个注释的地图视图。注释的标题是业务的名称，副标题是地址。注释视图上有一个detailDisclosure按钮，用于将用户带到所选注释的详细视图。详细视图的UILabel包含注释标题中的文本，UILabel包含注释副标题中的文本（地址），带有商业网站的按钮，带有商务电话号码的按钮，最后是获取按钮到地址的方向。我想从注释副标题中获取地址，以便当用户点击“获取方向”按钮时，它会打开Apple Maps应用程序中的地址，以便他们获取路线。我的问题是，如何使用注释副标题中的地址打开地图应用程序？

您需要使用MKMapItem -openInMapsWithLaunchOptions:记录的here。您需要先创建MKPlacemark，如果您有所需的坐标，则可以直接创建地标，如果您只有地址，则需要使用CLGeocoder。
