System Information

macOS Version 11.3.1 (Build 20E241)
Xcode 12.5 (18205) (Build 12E262)
Timestamp: 2021-05-22T23:12:23+08:00

网上有资料说打开Xcode，选取”File” > “Project Settings…” 选择 “Legacy Build System” 而不是 “New Build System（Default）” 即可解决，但实际上并不能解决问题。

我突然想起之前Add Frameworks时Embed状态老是默认选中“Embed & Sign”，看了一下DCUniVideoPublic.framework果然是“Embed & Sign”！

于是把它改成“Do Not Embed”然后重新点左上角三角图标运行（Build and then run the current scheme）一下就可以了！

另外，这次更新离线SDK后发现带来很多问题，比如被强制要求提供Bundle Identifier、包名、证书签名等才能使用，另外就算没有使用广告标识（IDFA）也会因包含NSUserTrackingUsageDescription而得修改App Store Connect上的App隐私否则过不了审核！所以建议直接在manifest.json中设置ignoreVersion为true以忽略版本检查提示框！

"app-plus" : {
        "compatible" : {
            "ignoreVersion" : true //true表示忽略版本检查提示框，HBuilderX1.9.0及以上版本支持  
        },
......
