You probably have a circular dependency/include. Use a forward declaration (@class MONClass;) rather than #importing the header. Since there is no physical dependence, you should be using a forward declaration in the first place (i.e. for much faster builds).
您可能有循环依赖/包含。使用前向声明 ( @class MONClass;) 而不是#importing 标头。由于没有物理依赖性，您应该首先使用前向声明（即更快的构建）。
So instead of:
所以而不是：
#import "VistaDereIzq.h"
use:
用：
@class VistaDereIzq;
and then add your #importto an .mfile as needed.
然后根据需要将您的添加#import到.m文件中。
