没有得到图像的索引值

Question

我在来自webservice的七个UITableView部分中有七个图像数组。数组图像数可能是1或2或3，但最大数量是6.在每个部分我有2个每行有3个数组图像的行。 我将三个图像视图命名为LeftImageview，middleImageview和rightImgaeview。

我正在将图像发送到Looksfullimage viewcontroller。但是在使用didSelectRowAtIndexPath:委托方法时，我正在选择部分，但没有获得image.can的索引值。任何人都建议如何获取图像的索引值相对于部分。

我还尝试获取图像的标记值并使用leftImagepressed动作在三个图像上应用按钮。我试图通过将类型为int的imagetagvalue保持为cellforRowAtIndexPath:委托方法中的某些不同来查找tableview的部分但我不是正确获取部分。我在看起来完整的图像视图控制器的图像视图命名照片图像视图。我需要的是当我点击我的视图的一部分中的任何图像，特定的图像应该显示在外观全图像视图控制器的照片图像视图。我是放置我的桌面视图的screeshot。 任何人都可以建议......

提前致谢。

Answer 1

你无法获得图像的索引路径，didSelectRowAtIndexPath会给你的是所选行的索引路径，其中包含3个图像。

您需要做的是扩展imageView类并在图像上实现触摸以找出单击的图像。

Answer 2

我将表格视图更改为滚动视图。并将标记应用于图像的每个按钮。现在工作正常......
