重现方式：

打包到苹果手机，第一次启动闪退，查看日志如上
第二次打开却正常了，不知道是什么原因

出现概率：必先
额外线索：
查了论坛，最接近的是这个

creator2.2.2打包到iOS平台，模拟器正常，真机闪退问题

huanxinyin · 2020年03月20日 03:18

是不是调用了evalString ？ JS 接口函数调用前最好定义下 se::AutoHandleScope hs;

blingame · 2020年03月20日 03:27

恩恩对的
`

(void)sendCocos:(NSMutableDictionary *)dict{

NSString *jsonString = [SDKUtils toJSONString:dict];
NSLog(@“Xcode::sendCocos===========jsonString = %@”,jsonString);

//TODO: 替换特殊符号 {“type”:1} —> {#type#:1}
jsonString = [jsonString stringByReplacingOccurrencesOfString:@""" withString:@"#"];
// OC -> js
std::string strRet = std::string([jsonString UTF8String]) ;
std::string jsCallStr = cocos2d::StringUtils::format(“onSDKAPI(”%s");", strRet.c_str());
se::Value *ret = new se::Value();
se::ScriptEngine::getInstance()->evalString(jsCallStr.c_str() , -1 , ret);

NSLog(@“XCode ,json = %@”,jsonString);

}
`
这个【se::AutoHandleScope】怎么加？

huanxinyin · 2020年03月20日 03:29

定义在函数最前面

blingame · 2020年03月20日 03:45

不知道是不是我写法有问题，
se::Value *ret = new se::Value(); se::AutoHandleScope hs; se::ScriptEngine::getInstance()->evalString(jsCallStr.c_str() , -1 , ret);

报另外一个错
class AutoHandleScope { public: AutoHandleScope() : _handleScope(v8::Isolate::GetCurrent()) // 这里报错了 { } ~AutoHandleScope() { }

blingame · 2020年03月20日 03:54

放到 sendCocos 方法，也是一样的报错
`

(void)sendCocos:(NSMutableDictionary *)dict{
se::AutoHandleScope hs;
…
}
`

huanxinyin · 2020年03月20日 04:41

不行就给个demo吧，我们这边复现不出你说的情况

blingame · 2020年03月20日 08:17

测试了很多遍，终于找到原因了！！！！！
我发现每次闪退的时候，都是卡在了IOS 请求商品信息完成后的回调（也就这里会导致闪退）
所以在调用 evalString 前，增加开启异步dispatch_async
修改代码如下：
`
// 请求商品信息后，通知Cocos
// [IOSInterface sendCocos:Type_RequestProductList:jsonDict];

// 开启异步，否则会闪退
dispatch_async(dispatch_get_main_queue(), ^{
[IOSInterface sendCocos:Type_RequestProductList:jsonDict];
});
`

初步猜测，商品信息request请求，卡主线程了,
..... SKProductsRequest *request = [[SKProductsRequest alloc] initWithProductIdentifiers:productIdSet]; request.delegate = self; [request start];
但很奇怪的是，使用了很久的代码，以前也没出现这个问题 =。=

我这边的解决方案，也是用异步，不知道引擎团队的大佬们，解决了没有

huanxinyin · 2020年03月30日 03:06

本身回调不是在主线程吧？evalString 必须在主线程才能调用，引擎设计就是这样的，所以你们的处理是必须，而且就是只能你们自己处理。
