在我完成应用程序构建的某个时刻，它出现了这个错误。我不记得在构建设置或类似的地方更改任何内容。有什么想法可能会发生这种情况吗？

答案 0 :(得分：4)
您项目中的某些内容可能会被误解为：
cannot find interface declaration for 'JCreateViewController'
您确定自己拥有JCreateViewController的界面和实现吗？
答案 1 :(得分：0)
我遇到了完全相同的问题，这可能有所帮助。
事实证明问题是：
self.sortByandFilterInformation.text = [NSString stringWithFormat:@"Sorted by %@ within %.2f m", self.sortByString,[BNUtilitiesQuick MaxDistanceOnSearch]];
结果是self.sortByString，应该返回一个字符串，返回＆＃34; void＆＃34;代替。我解决了这个问题，程序运行得很好。
是的我同意，这个错误很不清楚。尝试检查最近更改的代码，看看是否有与stringWithFormat一起使用的void函数。
