如何将来自 GitHub API 的 JSON 结果转换为 NSArray，以便填充 UITableView？

这是我得到的回复：

由于您的响应包含字典数组，因此在解析 json 后，您将获得一个NSArry字典。

// handle it
NSError *e = nil; 
NSArray *jsonArray = [NSJSONSerialization JSONObjectWithData: data options: NSJSONReadingMutableContainers error: &e]; 

if (!jsonArray) { 
    NSLog(@"Error parsing JSON: %@", e); 
} else { 
    NSLog(@"parsing done and array contains data");
}

在您的cellForRowAtIndexPathtableview 委托方法中，根据 indexpath 取出字典。

[jsonArray objectAtIndex:indexpath.row];

您返回的 JSON 结果本质上是一个 NSDictionary。在你的

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

拉出您想要的单个字典条目并将单元格文本设置为从字典返回的 NSString。您的特定行的 indexPath 可能会映射到字典的键，以使您的生活更轻松。
