Question

当Xcode到达最后一个“"EXC_BAD_ACCESS (code=EXC_ARM_DA_ALIGN"”语句以识别NSArray * objs的结束时，我收到此错误nil。

我看到其他评论类似的错误here和here但这些似乎与我遇到的情况无关。我错过了一些明显的事吗？有人遇到过这种情况么？

Answer 1

错误表明，您即将添加incompatible value type to the objects。

检查（确保）对象和放大器的值。 Keys在其之前具有Object（Null Value）值得到补充。

Answer 2

我猜您正在向数组添加原始类型（例如NSUInteger或int），而不是对象。确保将所有数字包装在NSNumber对象中。

使用EXC_BAD_ACCESS的NSArray obis命令的最后一个元素出错（代码= EXC_ARM_DA_ALIGN
