我有一个名为UIView的自定义CustomMarkerInfoWindow类，其中包含.h，.m和xib个文件。
在xib文件中，我有2个名为storeNameLabel和storeAddressLabel的标签，我已将CustomMarkerInfoWindow连接为2 IBOutlet。< / p>
出于某种原因，当我尝试创建这样的对象时：
CustomMarkerInfoWindow *infoWindow=[[[NSBundle mainBundle] loadNibNamed:@"CustomMarkerInfoWindow" owner:self options:nil] firstObject];
应用程序崩溃，我收到此崩溃消息：
Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<AroundersViewController 0x7fed34820400> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key storeAddressLabel.'

libc++abi.dylib: terminating with uncaught exception of type NSException
重要部分：this class is not key value coding-compliant for the key storeAddressLabel（如果我将storeAddressLabel的崩溃移除storeNameLabel的相同错误。
我已经搜索了几个小时的解决方案（我试图通过几种方式重新连接插座，尝试重新创建课程......）。
注意：我已经检查了this question，但它不适合我。
我真的不知道为什么会这样，有人可以帮帮我吗？
谢谢！
