设备中的EXC_BAD_ACCESS，而不是模拟器中的EXC_BAD_ACCESS [英] EXC_BAD_ACCESS in device, not in simulator

问题描述

我在项目中实现了adwhirl.我以前在我的项目中已经实现了它，所以我只是将它从以前的版本中合并到了我的当前项目中.

I have implemented adwhirl in my project. I have implemented it previously in my projects, so I just incorporated it into my current project from my previous.

- (UIViewController *)viewControllerForPresentingModalView {
{
  return self;
}

我在以前的项目中曾使用过此方法..因为我的window.rootvviewcontroller仅用于自我.但是在我当前的项目中，有很多屏幕用来展示广告，所以我使用了:

I had used this in my previous projects..since my window.rootvviewcontroller was self only. But in my current project there are many screens on which I am showing ads, so I have used:

- (UIViewController *)viewControllerForPresentingModalView {
    {
      return return [[(AppDelegate *)[[UIApplication sharedApplication] delegate] window] rootViewController] ;;
    }

主要问题是程序崩溃了，而且仍然如此.起初一切都还好:iads测试广告已加载，但很少崩溃.我很快了解到，这是因为 Admob .由于admob广告大部分时间未加载，因此崩溃很少.

The main problem is the program was crashing, and still is. At first everything was okay: iads test ads loaded up, but it crashed rarely. I soon understand it was because of Admob. It crashed rarely because admob ads were not loaded most of the time.

现在，在搜索这些崩溃时，我遇到了一个问题，因为我是用Xcode 4.2创建项目的，而不是以前的Xcode 4.0项目，所以在窗口和视图控制器中具有很强的属性.我删除了.

Now searching for these crashes, I came across a point that since I have made the project in Xcode 4.2 rather than my previous projects Xcode 4.0 there were strong attributes in my window and view controller. I removed it.

现在问题出在模拟器上，它没有崩溃，但它在设备上崩溃了.

Now the problem is in simulator it doesn't crash but it crashes in device.

错误是在我将adview添加为子视图之后，并且它-(UIViewController *)viewControllerForPresentingModalView 通过了此功能，但是之前 adWhirlDidReceiveAd 方法.

The error is after I have added adview as a subview and it has - (UIViewController *)viewControllerForPresentingModalView went through this function but before adWhirlDidReceiveAd method.

实际崩溃为 [GADRequestPrivate spamSignals] EXC_BAD_ACCESS.

您需要非常仔细地分析控制台，才能真正了解崩溃的原因.这对几乎所有未启用ARC的代码都有帮助.

You need to analyze your Console very carefully to see actually why the Crash occurs. This helped me in almost all of the Code that are without ARC enabled.
