假设
首先，您发布的 json 示例不是有效的 json，而是您在调试器中看到的输出。我假设 json 将类似于以下格式：
{
"appointments": [
{
"numApts": 1,
"title": "Coffee",
"scheduleDate": "2015-11-02"
},
{
"numApts": 2,
"title": "Shower",
"scheduleDate": "2015-11-04"
},
{
"numApts": 3,
"title": "Rollercoaster!!!!",
"scheduleDate": "2015-12-24"
}
]
}
TL;DR
我建议您创建一个Appointment代表单个约会的模型。然后，您应该创建一个包装器，用于存储所有约会，并根据工作日进行过滤。您可以为该包装器命名任何您认为适合您的项目的名称。
代码示例
我尝试为您想要实现的内容整理最简单的案例。希望代码中使用的命名具有足够的描述性以解释其本身。
我认为这对于回答您的问题并让您从这里开始有很大的帮助。我的代码的输出将类似于下图：
现在，我需要强调的是，在开始在生产中使用类似的东西之前，您需要注意这里和那里有一些力量展开。
