谢谢你，
nonono

How can I get the name of the [touch view] in the touchesbegan event. So if it were UIView *aaaaaview I would get aaaaaview as the return; Thank You, nonono

推荐答案

UIView * aaaaaView只是指内存中的一个地方。所以如果你有

"UIView *aaaaaView" just refers to a place in memory. So if you had

UIView *aView;
UIView *anotherView;
aView = anotherView;

并且用户触摸了一个UIView，视图的名称是aView还是anotherView？特别是，一个UIView不知道你用来存储它的变量的名称。

and the user touched a UIView, would the view's name be "aView" or "anotherView"? In particular, a UIView has no knowledge of the name of the variable you use to store it.

我想你将不得不初始化一个NSDictionary映射名称UIViews。

I think you're going to have to initialise an NSDictionary mapping names to UIViews.

您的-viewDidLoad中可能有以下内容：

Something in your -viewDidLoad like this, perhaps:

yourDictionary = [[NSDictionary alloc] initWithObjectsAndKeys:
                          @"aaaaaView", aaaaaView, @"viewTwo", viewTwo, nil];

，然后在您的活动中可以说

and then in your event you can say

NSString *viewName = (NSString *) [yourDictionary objectForKey: [touch view]];
