Question

我正在使用RestKit并遇到问题。我已经尝试了很多东西来解决这个问题，但没有成功。：）

- (void)objectLoader:(RKObjectLoader*)objectLoader didLoadObjects:(NSArray*)objects {
    NSLog(@"objects count: %d.", [objects count]);
    NSLog(@"editions count: %d.", [editions count]);
    [editions release];
    editions = [objects retain];
    NSLog(@"objects count: %d.", [objects count]);
    NSLog(@"editions count: %d.", [editions count]);
    Edition *edition = [objects objectAtIndex:0];
    NSLog(@"edition title: %@.", [edition title]);
}

以上代码的控制台是：

2012-03-07 18:02:58.477 AppName[2870:207] objects count: 1.
2012-03-07 18:02:58.478 AppName[2870:207] editions count: 0.

但是，它适用于模拟器：

2012-03-07 18:24:20.215 AppName[46315:207] objects count: 4.
2012-03-07 18:24:20.215 AppName[46315:207] editions count: 0.
2012-03-07 18:24:20.216 AppName[46315:207] objects count: 4.
2012-03-07 18:24:20.216 AppName[46315:207] editions count: 4.
2012-03-07 18:24:20.216 AppName[46315:207] edition title: Some String.

请帮助..任何形式的回复将不胜感激。谢谢。

ps：我还运行了RKTwitter示例。结果一样！它在模拟器上很棒，但在设备上产生了同样的错误。

pps：我已经尝试过RKTwitter样本用于master（Xcode4）和0.9-stable（Xcode3）分支。结果是一样的。它在模拟器上没问题，但在设备上失败了。

我在移植10.7以下的应用程序时遇到了同样的问题，似乎发生的事情是它将我的NSArray *对象包装在第二个数组中

(
 (
   <ITEM>
   <ITEM>
   <ITEM>
 )
)

这只发生在我的10.6目标上，所以获取真实对象就像查看数组的第一个索引是否为索引然后使用它一样简单。我猜它是一个错误/怪癖。或者我做错了什么，谁知道。
