- SWIFT 如何解析 JSON数组
-
[{"Date(time)":"2015-12-01","DayOfWeek(time)":"3","Time(time)":"11:38:23","Hour(time)":"11"},
{"Date(time)":"2015-12-02","DayOfWeek(time)":"4","Time(time)":"11:38:23","Hour(time)":"11"},
{"Date(time)":"2015-12-03","DayOfWeek(time)":"5","Time(time)":"12:38:23","Hour(time)":"12"},
{"Date(time)":"2015-12-04","DayOfWeek(time)":"6","Time(time)":"11:38:23","Hour(time)":"11"},
{"Date(time)":"2015-12-05","DayOfWeek(time)":"7","Time(time)":"11:38:23","Hour(time)":"11"}]以上JSON数组如何解析？是json数组 ，单个的json已经回解析了，下面是解析单个json的方法
var json : AnyObject = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.AllowFragments, error: nil)!
var name: AnyObject? = json[0].objectForKey("name")
解决方案
楼主理解错了，json没有单个和json数组之分，只有json里是数组还是字典的分别，楼主给出的数据可见该json数据是由一个数组包裹着5个字典组成，解析方法如下：
let resultArray = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.AllowFragments, error: nil) as? Array
resultArray则为包括着5个字典的数组。
还有目前swift2 后 JSONObjectWithData操作需要try catch :
写法1：
var resultDict: NSArray?
do {
resultDict = try NSJSONSerialization.JSONObjectWithData(nonNilData, options: NSJSONReadingOptions.MutableContainers) as? NSArray
} catch {
debugPrint("JSONObjectWithDataError: (error)")
}
写法2：
var resultDict = try? NSJSONSerialization.JSONObjectWithData(nonNilData, options: NSJSONReadingOptions.MutableContainers) as? NSArray
建议json解析完后转换成json的真实类型，不要继续拿着anyObject来使用：
例：如果json为字典 则： let MyDict = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.AllowFragments, error: nil) as? Dictionary
谢谢采纳
解决方案二：
解析 json 数组

可以用swiftjson这个第三方模块 封装很好
