iOS版.当其他代码已经使用NSSetUncaughtExceptionHandler时,我怎么能捕获异常？

此外,您可以存储SDK的处理程序,并在uncaughtExceptionHandler中调用它以使SDK协同工作.

示例代码：

static NSUncaughtExceptionHandler *exceptionHandler = NULL;

typedef void (*sighandler_t)(int);
static sighandler_t sigHandler = NULL;

static void handleException(NSException *E)
{
    //your code ...

    //call the SDK handler
    if (exceptionHandler) {
        exceptionHandler(E);
    }
}

static void handleSignal(int signal)
{
    //your code ...

    if (sigHandler) {
        sigHandler(signal);
    }
}

void installUncaughtExceptionHandler()
{
    // store the SDK handler
    exceptionHandler = NSGetUncaughtExceptionHandler();

    NSSetUncaughtExceptionHandler(&handleException);

    sigHandler = signal(SIGABRT,handleSignal);
    signal(SIGILL,handleSignal);
    signal(SIGSEGV,handleSignal);
    signal(SIGFPE,handleSignal);
    signal(SIGBUS,handleSignal);
    signal(SIGPIPE,handleSignal);
}
