objective-c - 如何通过 touch.view 和 isKindOfClass 选择对象？

Question

我有简单的 if case intouchesBegan方法：

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

我已经查看了许多Direction对象，当我点击一个我想选择它时，例如：

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

我可以在 obj-C 中做到这一点吗？或者我怎样才能正确地做到这一点？

Answer 1

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