Question

我上周一直在研究这个项目，一切都在模拟器中运行良好。就在今天晚上，当我去运行它时，我得到了大量全新的错误，而且自上次平滑构建/模拟以来我添加的唯一代码是从我刚创建的文件中添加字典。

我肯定处于Objective-C和Xcode学习曲线的陡峭部分，这些错误根本不响铃，因为我没有使用过我在项目中引用的任何代码，除非它们以某种方式与故事板中UI设计期间在幕后创建的代码相关。在此先感谢您的帮助！

以下是我用来添加词典的代码：

    - (void)calculate
    {
        // Retrieve the dictionary containing the chart
        NSString *path = [[NSBundle mainBundle] pathForResource:@"chart" ofType:@"plist"];
        NSDictionary *chart = [NSDictionary dictionaryWithContentsOfFile: path];


    }

这是错误日志：

这是iOS7中的一个已知错误......让它像这样......如果我是对的，那么每次都不会出现。目前没有可用的解决方法。尝试升级到7.0.3。有关详情，请查看this question。您可以在StackOverflow上找到大量此类问题。别担心..继续工作..如果您对我的答案仍然不满意，请告诉我。 .. :)我知道它不容易消化，但你必须...... :(
