iPhone SDK超越界限

Question

由于未知的例外'nsrangeException'，我正在使用一个“终止应用程序”，原因是：'*** - [nsarray objectatiNdex：]：索引24超越界限[0 .. 23]'“我不确定如何放置我的。 m在这里没有很长的时间。请让我知道如何协助解决这个问题。提前致谢！

事实证明，问题在于，图像并非全部复制到目标>复制捆绑包资源文件夹中，这就是使它崩溃的原因！？！？太感谢了！

Answer 1

错误说该数组有24个元素，但是您正在尝试访问第25个元素。因此，您需要发布试图访问25个元素的代码。或找出为什么它试图在24个元素数组中找到25个元素。

编辑：

您应该在tableview左右的第一行中设置一个断点：didSelectRowatIndExpath：

然后在GDB>提示类型上：

po descArray

要不就：

p(int) [descArray count]

或查看变量窗格，以查看当时实际上有多少个项目。如果需要，请重复其他两个阵列。

再次编辑：

您在我们的tableview中有另一个问题（可能是无关的）：numberFrowsInsection：

您始终返回contentList计数。该返回之后的线将永远无法达到包括NSLOGS。一旦您在C中获得第一次返回，您就会立即从该方法返回。我认为这不是您的直接问题，但是当您开始搜索工作时，这是另一个问题。

Answer 2

检查这些横幅中的对象数量descarray contentslist

这些数组的对象数量不等于表视图中的行数。

（您必须检查在哪里准备阵列，然后检查tableView dataSource并正确委派方法）。或者如果您没有获得解决方案，则在此处放置所有代码。
