NSArray.count返回不正确的巨型整数

Question

我有以下代码，用于从数组中选择一个随机字符串。

NSArray *popupMessages = [NSArray arrayWithObjects:
                          @"Shoulda' been bobbin' and weaving! Need anything from the shop?",
                          @"Don't forget you can use old boss's guns! Available in the shop!",
                          @"Hey Chaz, you Bojo! You need more POWER! Come by the shop for some better weapons!",
                          @"Aw… lame. Maybe I got something that can help you out here at my shop!",

                          nil];
int pmCount = popupMessages.count; // Breakpoint Here - pmCount = 971056545

int messageIndex = arc4random() % pmCount; // Breakpoint Here - same as above

我正在使用ARC和cocos2d。关于为什么数组的计数返回如此巨大数字的任何想法？谢谢！

Answer 1

您的问题看起来像是一个调试器工件。例如，它可能与优化相关。有时编译器会生成严重混淆调试器的代码。添加日志语句以确保调试器不只是告诉您谎言。

Answer 2

"count" is not a property, AFAIK

我通常得到数组计数的方式是：

[popupMessages count];

Answer 3

尝试：

NSInteger pmCount = [popupMessages count];
