在 控制台（console）打印 Stack Trace

创建一个方法（处理异常并输出到控制台）：

void uncaughtExceptionHandler(NSException *exception) 
{
    NSLog(@"CRASH: %@", exception);
    NSLog(@"Stack Trace: %@", [exception callStackSymbols]);
    // Internal error reporting
}

在 app delegate 中添加异常处理器（exception handler）：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{   
    NSSetUncaughtExceptionHandler(&uncaughtExceptionHandler);
    // Normal launch stuff
}

效果如下：
