如何通过touch.view和isKindOfClass选择对象？

Question

如果用touchesBegan方法中的情况，我会变得简单：

if ([touch.view isKindOfClass:[Direction class]])
{
    //select tapped object and do something...
}

我已查看了许多Direction个对象，当我点击其中一个时我想选择它，例如：

Direction *d = [touch.view].selectedObject; //something like that.

我可以在obj-C中这样做吗？或者我该如何正确地做到这一点？

Answer 1

if ([touch.view isKindOfClass:[Direction class]])
{
    //do something...
    Direction *d = (Direction*)[touch view];
}
