1、JSONString转换为字典
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | funcgetDictionaryFromJSONString(jsonString:String) ->NSDictionary{
letjsonData:Data=jsonString.data(using: .utf8)!
letdict=try?JSONSerialization.jsonObject(with:jsonData,options: .mutableContainers)
ifdict!=nil{
returndictas!NSDictionary
}
returnNSDictionary()
}
|
2、JSONString转换为数组
1 2 3 4 5 6 7 8 9 10 11 | funcgetArrayFromJSONString(jsonString:String) ->NSArray{
letjsonData:Data=jsonString.data(using: .utf8)!
letarray=try?JSONSerialization.jsonObject(with:jsonData,options: .mutableContainers)
ifarray!=nil{
returnarrayas!NSArray
}
returnarrayas!NSArray
}

3、字典转换为JSONString
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | funcgetJSONStringFromDictionary(dictionary:NSDictionary) ->String{
if(!JSONSerialization.isValidJSONObject(dictionary)) {
print("无法解析出JSONString")
return""
}
letdata:NSData! =try?JSONSerialization.data(withJSONObject:dictionary,options: [])asNSData!
letJSONString=NSString(data:dataasData,encoding:String.Encoding.utf8.rawValue)
returnJSONString!asString
}
|
4、数组转换为JSONString
1 2 3 4 5 6 7 8 9 10 11 12 13 | funcgetJSONStringFromArray(array:NSArray) ->String{
if(!JSONSerialization.isValidJSONObject(array)) {
print("无法解析出JSONString")
return""
}
letdata:NSData! =try?JSONSerialization.data(withJSONObject:array,options: [])asNSData!
letJSONString=NSString(data:dataasData,encoding:String.Encoding.utf8.rawValue)
returnJSONString!asString
}
