在APPDelegate里邊添加如下代碼:

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潰統(tǒng)計(jì)把日志上傳至服務(wù)器了,這時(shí)候就要調(diào)用第三方的方法把信息打印到本地.
