--------------------编程问答-------------------- 将方法改为：
- (NSManagedObjectModel *)managedObjectModel
{
    if (__managedObjectModel != nil)
    {
        return __managedObjectModel;

    NSURL *modelURL = [[NSBundle mainBundle] URLForResource:@"iBountyHunter" withExtension:@"momd"];
    __managedObjectModel = [[NSManagedObjectModel alloc] initWithContentsOfURL:modelURL];

就可以了。试试吧。 --------------------编程问答-------------------- 我也遇到过这样的问难 --------------------编程问答-------------------- --------------------编程问答-------------------- --------------------编程问答-------------------- 楼主，问题解决了吗，我也遇到同样的问题了 --------------------编程问答-------------------- 我下载了，运行是可以的，那就多半是你那边设置的问题了。你试试用lldb编译吧，4.6的Scheme在product里面，其他版本你自己找吧。edit scheme里面，info－》里面的debuger改成lldb。 --------------------编程问答-------------------- 这是因为你的coredata模型与数据库已经对不上了，你是不是改过coredata模型？ --------------------编程问答-------------------- 设下断点看看你的模型建立成功了吗很可能是楼上说的情况 --------------------编程问答-------------------- can I say goodbye to CoreData? --------------------编程问答-------------------- 这算挖坟么... --------------------编程问答-------------------- 除 --------------------编程问答--------------------
