与iOS 5.0 - objectAtIndexedSubscript一起发布的Aviary

Question

我已经下载了最新的Aviary代码2.6.0，并将其合并到我的Xcode 4.2中，用于运行iPhone 5.0的iOS 4S。每次我启动“航空行动”时，我都会在下面看到objectAtIndexedSubscript的回溯节目。

我看到了这个帖子“Is objectAtIndexedSubscript available in IOS5?”，在iOS 5.0中没有objectAtIndexedSubscript。在Aviary文档中，它说支持iOS 5.0。我错过了什么？

这是我的问题。是否有人试图将最新版本2.6.0用于iOS 5.0的Aviary代码集成？如果不是，那么Aviary版本适用于iOS 5.0吗？在哪里可以下载更早版本的Aviary。我只是还没有准备好转到iOS 6.0。我正试图把这个bug报告给Aviary支持部门，但是我觉得他们会告诉我升级到iOS 6.0。

来自“航空”网站：

运行时要求SDK支持的最低iOS版本是iOS 5.0。这一选择的主要原因是我们使用了ARC (自动参考计数)，以及我们对许多需要iOS 5的苹果框架和库的依赖。“

- (void) launchPhotoEditorWithImage:(UIImage *)editingResImage highResolutionImage:(UIImage *)highResImage
{    

    NSLog(@"launchPhotoEditorWithImage ...");

    // Initialize the photo editor and set its delegate
    AFPhotoEditorController * photoEditor = [[AFPhotoEditorController alloc] initWithImage:editingResImage];
    [photoEditor setDelegate:self];

    NSLog(@"Present photo editor ...");

    // Present the photo editor.
    [self presentViewController:photoEditor animated:YES completion:nil];
}

添加这个家伙类别(从github链接获得)，它将完美地工作。

只需更新到最新的Xcode。在一些旧版本的Xcode中，objectAtIndexedSubscript:不是在SDK中实现的。
