从coredata中删除对象时，应用程序崩溃时出错

I am storing some data in data. when i click on button the data in the coredata will be delete. I am using the below code.

我在数据中存储了一些数据。当我点击按钮时，coredata中的数据将被删除。我使用以下代码。

NSManagedObjectContext *context = [[YPOAppDelegate sharedAppDelegate] managedObjectContext];
NSManagedObjectModel *model = [[YPOAppDelegate sharedAppDelegate] managedObjectModel];

for (NSEntityDescription *entity in model) {
     NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
     [fetchRequest setEntity:entity];
     [fetchRequest setIncludesSubentities:NO];
     NSArray *objects = [context executeFetchRequest:fetchRequest error:nil];
     NSLog(@"objects ===%d",objects.count);
     for (NSManagedObject *managedObject in objects)
     {
            [context deleteObject:managedObject];
     }
}

NSError *err;

[context save:&err];

It's getting an error and app is crashed that is Terminating app due to uncaught exception 'NSObjectInaccessibleException', reason: 'CoreData could not fulfill a fault for '0x7e3937f0

由于未捕获的异常'NSObjectInaccessibleException'导致应用程序崩溃，即终止应用程序，原因是：'CoreData无法解决'0x7e3937f0的错误

Before deleting please weather you have that particular object or not ?

在删除之前请天气你有特定的对象吗？

if ([ListObjetcts existingObjectWithID:objects.objectID error:&error])
    {

    }
