iOS:First throw call stack 不显示具体

iOS:First throw call stack 不显示具体函数的解决方法:

定义一个异常捕获函数

static void uncaughtExceptionHandler(NSException *exception) {
     NSLog(@"%@\n%@", exception, [exception callStackSymbols]);
 }

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { 
    NSSetUncaughtExceptionHandler(&uncaughtExceptionHandler);
    return YES;
}
