@DCloud_iOS_XHY

云端打包还是本地离线打包，请提供复现问题的应用示例。

是用iOS开发工具Xcode运行打包的

回复 zzzzzzz_H5: 是提供demo吗还需要其他的资料吗

怎么联系您

回复 DCloud_IOS_XTY: 你这个应该是SDK集成吧，请提供可以复现问题的工程加我QQ

该问题是由于原生层插件书写不规范导致，具体原因如下： 同步方法必须要有返回值 -(void)methodSync:(PGMethod*)args {

}
改为：
-(NSData*)methodSync:(PGMethod*)args {
…
retrun data;
}

请问怎么解决的

这是iOS13下WKWebView与uni-app内核PDRCore的兼容性问题。主要原因是WKWebView的JavaScript prompt回调处理存在线程安全问题，导致objc_msgSend崩溃。

解决方案：

  1. 更新HBuilderX到最新版本（2.7.14+），官方已修复此问题
  2. 临时解决方案是在manifest.json中配置：
"ios": {
    "WKWebview": false
}
