编辑 - 我最近在 Git 上发布了一个关于如何解决这个问题的教程......下面是一个链接 https://github.com/lukejgeger/ESPN-API-Example.git
我正在使用 ESPN API，并试图用 NBA 中的所有球队填充表格 View 。我正在使用 restkit 并遇到了一些问题。
下面是一些代码
RKURL *baseURL = [RKURL URLWithBaseURLString:@"http://api.espn.com"];
RKObjectManager *objectManager = [RKObjectManager objectManagerWithBaseURL:baseURL];
objectManager.client.baseURL = baseURL;
RKObjectMapping* taskMapping = [RKObjectMapping mappingForClass:[Team class]];
[taskMapping mapKeyPath:@"name" toAttribute:@"teamName"];
[objectManager.mappingProvider setObjectMapping:taskMapping forResourcePathPattern:@"/teams"];
[objectManager loadObjectsAtResourcePath:[NSString stringWithFormat:@"/v1/sports/basketball/nba/teams?apikey=%@",kAPIKey] delegate:self];
[objectManager.mappingProvider setMapping:taskMapping forKeyPath:@"name"];
我收到响应代码 200，但我收到了错误
231 Encountered errors during mapping: Could not find an object mapping for keyPath
下面是我为团队返回的 JSON 的完整响应

最佳答案
你的问题在这里:
[objectManager.mappingProvider setMapping:taskMapping forKeyPath:@"name"];
由于 taskMapping 将“name”映射到“teamName”，为 keyPath“name”分配该映射将导致以下搜索:“name.name”，这显然不是您想要的。其余代码似乎是正确的，我只是删除该行，您应该没问题。

文章目录前言核心逻辑配置iSH安装Python创建Python脚本配置启动文件测试效果快捷指令前言iOS快捷指令所能做的操作极为有限。假如快捷指令能运行Python程序，那么可操作空间就瞬间变大了。iSH是一款免费的iOS软件，它模拟了一个类似Linux的命令行解释器。我们将在iSH中运行Python程序，然后在快捷指令中获取Python程序的输出。核心逻辑我们用一个“获取当前日期”的Python程序作为演示（其实快捷指令中本身存在“获取当前日期”的操作，因而此需求可以不用Python，这里仅仅为了演示方便），核心代码如下。>>>importtime>>>time.strftime('%Y-%
