UITapGestureRecognizer选择器，sender是手势，而不是ui对象 [英] UITapGestureRecognizer selector, sender is the gesture, not the ui object

问题描述

我有一系列使用标签识别的图像视图。我为图像添加了一个轻击手势。

I have a series of imageviews that I identify using their tag. I have added a single tap gesture to the images.

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(selectImage:)];
[tableGridImage addGestureRecognizer:singleTap];
tableGridImage.userInteractionEnabled = YES;
[singleTap release];

这设法调用selectImage选择器ok，但将手势作为发送者传递。我需要imageview作为发件人，所以我可以得到标签。

This manages to call the selectImage selector ok, but passes the gesture as the sender. I need the imageview as the sender so I can get the tag.

关于如何获取imageview及其标签的任何想法？

Any ideas on how I can get the imageview and it's tag?

推荐答案

我想出了如何获取标签，这对我来说是问题中最重要的部分。由于手势是发件人，我发现它所附带的视图随之发送：

I figured out how to get the tag, which was the most important part of the question for me. Since the gesture is the sender, I figured out the the view it is attached to is sent along with it:

[(UIGestureRecognizer *)sender view].tag

如果有人能告诉我如何发送参数，我仍然很好奇通过UITapGestureRecognizer选择器。

I am still curious if anyone can tell me how to send an argument through a UITapGestureRecognizer selector.
