在APPDelegate里边添加如下代码:

voiduncaughtExceptionHandler(NSException*exception) {

NSLog(@"CRASH: %@", exception);

NSLog(@"Stack Trace: %@", [exception callStackSymbols]);

// Internal error reporting

}

- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions{

NSSetUncaughtExceptionHandler(&uncaughtExceptionHandler);

// Normal launch stuff

}

如果仍然看不懂打印信息,可能是某些第三方崩溃统计把日志上传至服务器了,这时候就要调用第三方的方法把信息打印到本地.
