NSMutableArray EXC_BAD_ACCESS (code=1)
提问by ajnet
I have no idea why, but my NSMutableArray 'items' will not take more than 5 elements.
我不知道为什么，但我的 NSMutableArray 'items' 不会超过 5 个元素。
Can someone please help? I'm following the Big Nerd Ranch iOS Programming book.
有人可以帮忙吗？我正在关注 Big Nerd Ranch iOS 编程书。
This code works fine:
这段代码工作正常：
NSMutableArray *items = [[NSMutableArray alloc] init];
for (int i = 5; i < 10; i++) {
BNRItem *p = [BNRItem randomItem];
[items addObject:p];
}
However if I change the initial value of i to 4 or less the program crashes when exiting the for loop:
但是，如果我将 i 的初始值更改为 4 或更少，则程序在退出 for 循环时会崩溃：
NSMutableArray *items = [[NSMutableArray alloc] init];
for (int i = 4; i < 10; i++) {
BNRItem *p = [BNRItem randomItem];
[items addObject:p];
}

In the screenshot you posted in your comments you are adding a C string, "Mac", to your randomNounListarray. You need to make this an NSString with an @ symbol.
在截图中你在你发表的评论要添加一个C字符串，"Mac"以你的randomNounList阵列。您需要将其设为带有 @ 符号的 NSString。
I suspect the crash is occurring when this entry is randomly selected.
我怀疑是随机选择此条目时发生崩溃。
I'm surprised this compiled, I suspect you are ignoring some warnings.
我很惊讶这个编译，我怀疑你忽略了一些警告。
