我的应用程序崩溃的核心数据有问题。当我尝试将对象添加到关系时会发生这种情况。
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:]: index 25 beyond bounds [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。它深入到框架中，所以我不能调试很多。这从来没有发生过。我已经检查并重新检查了核心数据模型。有人知道什么是错的吗？
