我的核心数据存在问题，导致我的应用程序崩溃。当我尝试将对象添加到关系中时会发生这种情况。
HOMUser *artist = [HOMUser GetUserWithDictionary:artistDict inContext:context];
[self addMArtistsObject:artist];
*由于未捕获的异常'NSRangeException'而终止应用程序，原因：'* - [__ NSArrayM objectAtIndex：]：索引25超出边界[0 .. 24]'
数字25表示核心数据模型中有多少实体。这是调用堆栈。它进入框架很远，所以我不能调试很多。这从来没有发生过。我检查并重新检查了核心数据模型。有没有人知道可能出现什么问题？
