另外，有没有一本书或一些网站可以让我学习如何阅读崩溃日志？



更新： 这是代码expandWindowForDownload

- (void)expandTheWindowForDownload
{
    // Get the window size
    NSRect frame = [window frame];
    frame.origin.y += frame.size.height - 201;
    frame.size.height = 201;

    // Apply it
    [window setFrame:frame display:YES animate:YES];
}

以下是我通常寻找的东西：

异常类型

这通常可以帮助您了解基本问题是什么。在您的情况下，异常类型是 EXC_BAD_ACCESS：

Exception Type:  EXC_BAD_ACCESS (SIGSEGV)

正如 Google、Stack Overflow 或 Apple 会告诉您的那样，当您在释放对象后尝试访问它时，就会发生此类错误。（造成这种情况的一个常见根本原因是，如果您“过度释放”一个对象 - 即您对一个对象调用 release 方法的次数比它被保留的次数要多。）

当您从产品菜单运行“分析”时，Xcode 经常可以找到此类错误的来源。（如果我没记错的话，在 Xcode 3 中，它是 Build 菜单中的“Build and Analyze”。）所以试一试，它可能会节省一些时间。否则...

崩溃的线程

你会在崩溃日志的顶部找到它，就在异常类型的正上方。在你的情况下，你有：

Crashed Thread:  7

这允许您丢弃崩溃日志的大部分内容，而只专注于导致崩溃的线程。所以你感兴趣的是这个：

Thread 7 Crashed:

15  libsystem_c.dylib               0x00007fff8a611b75 thread_start + 13

现在，您可以从上到下处理此堆栈跟踪，直到您从自己的代码中进行第一次调用。（理论上，崩溃可能是由 Apple 代码中的错误引起的，但实际上它几乎总是我们的代码，而不是他们的。）

所以对你来说，事情开始出错的代码行是：

8   com.BirdiCode.SoundCloud_Downloader 0x0000000100015682 -[SoundCloud_DownloaderAppDelegate expandTheWindowForDownload] + 654

查看该expandTheWindowForDownload方法，看看您是否可以发现您正在访问已发布对象的位置。如果您无法发现，请在此处发布该方法的代码，我们应该能够找到答案并帮助您了解问题所在。

好的，因此对于查看此内容的任何人，我都找到了问题的解决方案。

似乎如果您调整窗口大小并且用户在窗口调整大小时“聚焦”在 NSTextField 上，则可能会导致崩溃。这发生在除 NSForm 之外的所有文本输入上。

此问题发生在 10.7.2 和 10.7.3 上。我还没有在任何其他版本的 mac os x 上尝试过。

为了解决这个问题，我刚刚在窗口调整大小调用[textField setEditable:NO];之前和之后调用。[textField setEditable:YES];

无论如何，感谢您的帮助！
