我一直在建设这个项目几个月，在模拟器和iPad这两个测试与像我有现在的一个没有任何问题。 突然间，我再也不能在我的iPad上成功的GET请求映射从我的Rails应用程序的核心数据对象。 我有在模拟器上没有问题。
当应用程序启动，我想提出一个大的GET请求，如果没有在核心数据的任何数据。 这里是（在使用模拟器AKA）的成功案例是什么RestKit日志：

当我尝试在我的iPad，RestKit记录进行CompetitionContest线（3日从底部）的一切，但当时它只是坐在和无限期地认为。 iPad上的核心数据库中有0行的所有实体。 这里是启动GET请求的代码：
[self.manager
getObjectsAtPathForRouteNamed:@"get_data"
object:nil
parameters:nil
success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult)
{
RKLogInfo(@"Load complete: Table should refresh...");
[self fetchCompetitions]; //method that makes a fetch request to core data to populate self.competitions
if (self.competitions == nil || self.competitions.count == 0)
{
UIAlertView *noGamesScheduled = [[UIAlertView alloc] initWithTitle:@"Error!" message:@"Insert alert message here." delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
[noGamesScheduled show];
}
else
{
[self.collectionView reloadData];
}
}
failure:^(RKObjectRequestOperation *operation, NSError *error)
{
RKLogError(@"Load failed with error: %@", error);
}];
我的映射和一切都因为它的工作在模拟器上就好了要罚款。 什么是模拟器和我的iPad之间的区别！？！
