我用这种方式解决了我的问题：
这似乎是Xcode的一个bug…1。请检查视图控制器的目标，脚本文件应该位于同一目标中。 2.选择您的xib并删除映射到该故事板的类，然后将其映射回，并在粘贴类后按enter键。nib名称保持不变，以便测试。 3.如果此按钮正在从自定义视图加载到视图控制器，则需要检查自定义视图是否已添加到正确的目标，并再次使用iAction重新映射内部润色
这就是我可以通过查看您的对话来了解的。您是否检查了iAction是否正确连接到按钮？或者你把photoLibraryButtonTapped方法称为哪里？@teja yeap，仔细检查。一切正常，您在IB中将类设置为您的
UIViewController
