原来问题是图像没有全部复制到 Target>Copy Bundle Resources 文件夹中，这就是导致它崩溃的原因！？！？太感谢了！

该错误表明该数组有 24 个元素，但您正在尝试访问第 25 个元素。因此，您需要发布尝试访问第 25 个元素的代码。或者弄清楚为什么它试图在 24 元素数组中找到第 25 个元素。

编辑：

您应该在 tableView:didSelectRowAtIndexPath 的第一行左右设置断点：

然后在 gdb> 提示符下键入：

po descArray

要不就：

p(int) [descArray count]

或者查看变量窗格以查看此时 descArray 中实际有多少项。如有必要，对其他两个阵列重复。

再次编辑：

您在我们的 tableView:numberOfRowsInSection 中有另一个问题（可能不相关）：

您一直返回 contentList 计数。将永远不会到达该返回之后的行，包括 NSLogs。一旦你在 C 中第一次返回，你将立即从该方法返回。我不认为这是您的直接问题，但这是当您开始搜索工作时会发生的另一个问题。

检查这些bannerImages descArray contentsList 中的对象数量

这些数组的对象数不等于表视图中的行数。

（您必须检查您准备数组的位置，然后正确地检查 tableview 数据源和委托方法）。或者如果您没有得到解决方案，请将所有代码放在这里。
