iOS生成随机消息

你好，这是我正在做的iOS项目。 我只是一个编写iOS应用程序的初学者。

我只需要帮助，以便改进>将您的消息放入NSMutableArray中，我认为以下方法对于您的目的来说已经足够好了：

+ (void) randomOrderedMutableArray:(NSMutableArray *) array
{
    int count = [array count];
    for (int i = 0; i < count; ++i)
    {
        int nElements = count - i;
        int n = (arc4random() % nElements) + i;
        [array exchangeObjectAtIndex:i withObjectAtIndex:n];
    }
}

+（void）randomOrderedMutableArray:（NSMutableArray*）数组
{
int count=[数组计数]；
对于（int i=0；i

你说的是生成对人类读者有意义的随机句子，因为如果你是，这本身就是一个大学博士研究课题，任何人都无法回答。如果你已经有100个句子，你想随机挑选它们，那就不同了。哪一个？@Martin，我的记事本里有100个句子。我有这样做的想法，但我的线程在AppDelegate.M，NSarray上不断断开，进行100次确认，并使用x=arc4random_uniform。我尝试了很多方法，即使是ipsum，但没有运气：（我仍然在尽我最大的努力使之成为可能。如果一个新手或高年级学生攻克了一个博士研究课题，那么他们就不需要一个博士学位来认可他们的技能。@MartinH，我刚刚包括了100个句子的例子。看一看。我是NSmutable数组的新手。我可以这样做吗：NSmutable数组*affirmation=@[@“你好”，“gg”，@“杀死他们”]；？事实上正是这样。让我试着用这个方法。因为我也用谷歌搜索过这样的方法：NSString*a=@“a”；NSMutableArray*array=[NSMutableArray arrayWithObjects:a，nil]；因此，我需要将其附加到AppDelegate.m？或viewtodocontroller.m？这很方便，因为当我围绕viewtodocontroller进行调优时，我不断出现线程中断。与其他人一样，我可能有点不清楚，但看起来您想要的是创建一个随机选取的短语列表。您可以在viewDidLoad或ViewDid出现在您的视图控制器中。而不是在AppDelegate中。我得到的错误是“NSarray没有可见的@interface，但我的接口是Assembly。h是接口Assembly:NSObject{NSarray*Assembly；}”
