无法在 xib 文件中正确设置 IBOutlet Swift IOS
Unable to set IBOutlet correctly in xib file Swift IOS
我是 Swift 的新手，我正在尝试在我的 Flutter 项目中实施原生 google 广告。我按照文档一步一步地在 swift 中创建原生广告，但现在我无法 link 我工厂的出口。
我试图 link 将视图拖到工厂 class :
但是我收到了这个错误：
*** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<NSObject 0x28140cd90> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key advertiserView.'
terminating with uncaught exception of type NSException
似乎是第一个插座导致崩溃，因为它无法识别它。
根据 documentation 我按照这个实现，代码中没有 IBOutlet，只有 linked inside the .xib file.
如何正确执行此操作？
检查您的 Runner 文件夹中是否有 GADNativeAd 头文件。
要创建头文件，只需右键单击 Runner 文件夹 => 新建文件...，然后选择 Header。
将其命名为GADNativeAd并将下面的代码复制到里面。您现在可以绑定网点了。
