Error : expected specifier-qualifier-list before ‘class’ | 小黑屋

https://bcuichina.wordpress.com/2011/06/07/error-expected-specifier-qualifier-list-before-‘class

Cocoa CustomView 画图 →. Error : expected specifier-qualifier-list before ‘class’. 如果编译BClass的时候出现下面的错误 expected specifier-qualifier-list before ‘AClass’ 当出现这种错误的时候说明AClass没有被import,如果已经import这个类了，说明AClass和BClass 之间有Circle引用。也就是说AClass import BClass，BClass import了 AClass。解决的办法是在AClass.h中用@Class BClass;，然后在AClass.m中#import "BClass.h"。 By cui415 .
