-[UITableViewCellScrollView _tableView]: unrecognized selector sent to instance 0x166a1960
-[UITableViewCellScrollView _tableView]: unrecognized selector sent to instance 0x166a1960

我试图为 - [NSObject（NSObject）doesNotRecognizeSelector：]添加符号断点但是没有显示哪个代码发送了那个选择器

更新：这次我使用了模拟器，并试图让应用程序崩溃，我现在得到了这个：

Answer 1

通过对单元格应用一些着色，我看到当我从附件视图中滑动单元格时崩溃

enter image description here

解决方法是在tableView中将accessoryType设置为UITableViewCellAccessoryNone：cellForRowAtIndexPath：

cell.accessoryType = UITableViewCellAccessoryNone;

Answer 2

嘿〜我刚刚在我的自定义UItableview Cell中删除了以下代码，但我不知道它是否可以帮到你

self.contentView.userInteractionEnabled = NO;

在我的情况下，当我尝试在iOS7中的自定义userinteractionEnabled中向左或向右滑动时，禁用单元格内容视图的UItableView会导致完全相同的崩溃，它应该通过删除来修复

Answer 3

考虑到你所得到的错误以及这些问题：

0x01ac90ee _CF_forwarding_prep_0 + 14
0x00785f7a -[UITableViewCellScrollView gestureRecognizerShouldBegin:] + 203

似乎您以某种方式将UITableViewCellScrollView的实例设置为手势识别器的代理。由于UITableViewCellScrollView可能没有实现UIGestureRecognizerDelegate协议，因此最终会出现无法识别的选择器异常。

仔细检查每个表格单元格中的手势识别器，并检查其代表的身份。

在左侧滑动时，表格视图在ios 7上崩溃
