我正在使用 RestKit 并遇到了一个问题。我已经尝试了很多方法来解决这个问题,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]);
}
上面代码的控制台是:
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..任何形式的回应将不胜感激。谢谢你。
ps:我也运行了 RKTwitter 示例。结果是一样的!它在模拟器上很棒,但在设备上产生了同样的错误。
pps:我已经为 master (Xcode4) 和 0.9-stable(Xcode3) 分支尝试了 RKTwitter 示例。结果是一样的。在模拟器上没问题,但在设备上失败了。
