NSArrayM insertObject：atIndex：]：object不能为nil' [英] NSArrayM insertObject:atIndex:]: object cannot be nil'

问题描述

经过大量搜索，并尝试使用stackoverflow上的一些解决方案，我没有找到任何可以解决我的错误的答案：
我有一个UIViewcontroller，谁的名字是WorldViewController。在这个UIViewcontroller中，我有一些UIViews。我想从一些UIViews修改一些依赖于WorldViewController的变量。现在，我把这些行：

After a lot of search, and tries with some solutions on stackoverflow, i didn't find any answer which could solve my error : I have a UIViewcontroller, who's name is WorldViewController. In this UIViewcontroller, i had init some UIViews. I want to modificate some variables which depends of WorldViewController from some UIViews. And now that i put those lines :

WorldViewController * World = [[WorldViewController alloc] init];

它给了我：

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSArrayM insertObject:atIndex:]: object cannot be nil'

那么，如何修复它？它可能来自WorldViewController正在运行的事实吗？那么，如何修复呢？

So, how to fix it ? Could it comes from the fact that WorldViewController is running ? And so, how to fix it ?

编辑：我的viewcontroller的init方法

Edit : init method of my viewcontroller

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization

        World1 = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 480.0)];
        [World1 setBackgroundColor:[UIColor blackColor]];
        [self.view addSubview:World1];
        [World1 release];

        [self.view addSubview:ViewPig];
        [self.view addSubview:level1view];
        [self.view addSubview:level2view];
        [self.view addSubview:LoadView];
        [LoadView AnimPigLoadingWith:PigChargement];
        [LoadView AppearLabelLoading];
        [self.view addSubview:FondPauseGrise];
        [self.view addSubview:FondPause];
        [self.view addSubview:BoutonResume];
        [self.view addSubview:BoutonHome];
        [self performSelector:@selector(Chargement) withObject:nil afterDelay:0.5];
        [self performSelector:@selector(ViewAppears) withObject:nil afterDelay:5.5+2.5];
        [self performSelector:@selector(LabelPrevientDepartWithImage:) withObject:Trois afterDelay:9];
        [self performSelector:@selector(LabelPrevientDepartWithImage:) withObject:Deux afterDelay:10];
        [self performSelector:@selector(LabelPrevientDepartWithImage:) withObject:Un afterDelay:11];
        [self performSelector:@selector(LabelPrevientDepartWithImage:) withObject:Go afterDelay:12];
        [self performSelector:@selector(Lancement) withObject:nil afterDelay:(3)];
        [self performSelector:@selector(GestionMaps) withObject:nil afterDelay:(11+2)];
    }
    return self;
}

谢谢！

推荐答案

您的问题中没有列出足够的代码来明确显示您出错的位置。

You haven't listed enough code in your question to definitely show where you're making an error.

查看您的问题任何表示 insertObject：atIndex：的行的代码。您插入的对象显然为零。

Look in your code for any lines that say "insertObject:atIndex:". The object you're inserting is apparently nil.

如果找不到此行，在符号 [NSArray insertObject：atIndex：] 上添加符号断点（单击链接以查看答案中的具体说明）与你的密切相关的问题）并看看你是否可以在崩溃发生之前就打破它。

If you can't find this line, add a symbolic breakpoint on the symbol "[NSArray insertObject:atIndex:]" (click the link to see specific instructions in an answer of a closely related question to yours) and see if you can break on it right before the crash happens.
