Question

我有一个json对象日：

days = {"available_hours":{ 
    "Monday" : [ ["5:30 am","11:00 am"] , [“1:00 pm","4:00 pm”], ["4:00 pm”,  "9:00 pm"] ]
    "Tuesday" : [ [“2:30 pm","7:50 pm"] ]
    "Friday" : [ [“7:30 am","12:50 pm"], [“4:00 pm","11:59 pm”] ]
}

我希望每天都能获得一个列表，并将可用小时数作为字符串。

 ["Monday 5:30 am - 11:00 am, 1:00 pm - 4:00 pm, 4:00 pm - 9:00 pm”, "Tuesday 2:30 pm","7:50 pm",etc ]

我正在使用此函数来处理数据，我每天都会传递JSON对象：

private func hoursList(shifts: [[String]]) -> String{
    var shiftslist: [String] = []
    var shifttext: String = ""
    for shift in shifts {
        shifttext += "\(shifts[0]) - \(shift[1])"
        shiftslist.append(shifttext)
    }  
    return join(", ", shiftslist)
}

问题是我无法通过任何一天，因为它不能转换为[[String]]

这对我有用：

   // Int from JSON
func getIntFromJSON(data: NSDictionary, key: String) -> Int {

    let info : AnyObject? = data[key]

    if let info = data[key] as? Int {
        return info
    }

    else {
        return 0

    }

}

// Array from JSON
func getArrayFromJSON(data: NSDictionary, key: String) -> NSArray {

    let info : AnyObject? = data[key]

    if let info = data[key] as? NSArray {
        return info
    }

    else {
        return []

    }

}
//Object from JSON
func getObjectFromJSON(data: NSDictionary, key: String) -> AnyObject {

    let info : AnyObject? = data[key]

    if let info: AnyObject = data[key] {
        return info
    }

    else {
        return []

    }

}
// String from JSON
func getStringFromJSON(data: NSDictionary, key: String) -> String {

    let info : AnyObject? = data[key]
    println(data[key])
    if let info = data[key] as? String {
        return info
    }

    return ""
}

您必须通过使用密钥传递JSON来调用该函数。

    var available_hours = self.getArrayFromJSON(JSONString as! NSDictionary, key: "available_hours")

    // Passing available_hours to get the values for sub-array
    var Tuesday = self.getStringFromJSON(available_hours as! NSDictionary, key: "Tuesday")
