Main.m 中的 iOS SIGABRT(提供回溯)

Question

在 main.m 中获取 SIGABRT 错误。我已经从控制台列出了回溯跟踪，以查看是否有人可以为我指明正确的方向。

#0  0x94d77c5a in __kill ()
#1  0x94d77c4c in kill$UNIX2003 ()
#2  0x94e0a5a5 in raise ()
#3  0x94e206e4 in abort ()
#4  0x94d9cb1b in _Unwind_Resume ()
#5  0x012abe39 in CFRunLoopRunSpecific ()
#6  0x012abccb in CFRunLoopRunInMode ()
#7  0x002c12a7 in -[UIApplication _run] ()
#8  0x002c2a9b in UIApplicationMain ()
#9  0x000028d9 in main (argc=1, argv=0xbfffec90) at /      Users/user-   
    name/Desktop/ProjectFive/ProjectFive/ProjectFive/main.m:20
#10 0x00002825 in start ()

这是我能够复制的核心转储信息。 SIGABRT 发生在我的 main.m 中的自动释放语句中

NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
int retVal = UIApplicationMain(argc, argv, nil,      
NSStringFromClass([ProjectFiveAppDelegate class]));
    [pool release];
    return retVal;

Answer 1

这可能是未捕获异常的结果。您应该尝试使用以下方法之一来追踪问题:

1. 分析接近失败的源代码
2. 一个源代码调试器(将其设置为在异常抛出时中断)
3. Coverity Static Analysis、Clang Static Analyzer 等静态检查器，或者只是启动编译器警告
4. 动态检查器，如 Electric Fence、Klee 或 valgrind (helgrind/memcheck)
