仪器在 main.m (Xcode 4.3.1) 中显示泄漏 [英] Instruments show leak in main.m (Xcode 4.3.1)

问题描述

我正在使用 ARC 开发应用程序在检测内存泄漏的仪器中分析我的应用程序时，它会在以下函数中显示泄漏:

I am developing an app using ARC When profiling my app in instruments for memory leaks it shows leaks at the following function:

#import <UIKit/UIKit.h>

#import "AppDelegate.h"

int main(int argc, char *argv[])

{
    @autoreleasepool { 
       return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
    }
}

这是否表明我的代码中的其他地方有问题?

Does this indicate a problem somewhere else in my code?
