字典 转成 字符串: 下面有写好的扩展你可以直接使用

var dictionary = [[String:Any]]()        let dict1 = ["age":"22","ddd":"gg"]        let dict2 = ["age":"33","w":""]        dictionary.append(dict1)        dictionary.append(dict2)        let data = try? JsONSerialization.data(withJsONObject: dictionary,options: [])        let str = String(data:data!,enCoding: String.EnCoding.utf8)!        print(str )

字符串 转成 字典:

let Json:String = (CHUser.shareInstance.userInfo?.tag_data)!        //Json = Json.replacingOccurrences(of: "/",with: "") //加上这句直接打印可中文                guard let JsonData = Json.data(using: .utf8) else {            return        }        do {            let dict = try JsONSerialization.JsonObject(with: JsonData,options:JsONSerialization.ReadingOptions.mutableContainers)            print(dict)        } catch  {            print("失败")        }

2016年11月29日 封装了一下

extension String  {        var md5: String! {        let str = self.cString(using: String.EnCoding.utf8)        let strLen = CC_LONG(self.lengthOfBytes(using: String.EnCoding.utf8))        let digestLen = Int(CC_MD5_DIGEST_LENGTH)        let result = UnsafeMutablePointer<CUnsignedChar>.allocate(capacity: digestLen)                CC_MD5(str!,strLen,result)                let hash = NSMutableString()        for i in 0..<digestLen {            hash.appendFormat("%02x",result[i])        }                result.deallocate(capacity: digestLen)                return String(format: hash as String)    }        var toAny:Any! {        guard let JsonData = self.data(using: .utf8) else {            return nil        }                do {            let any = try JsONSerialization.JsonObject(with: JsonData,options:JsONSerialization.ReadingOptions.mutableContainers)            return any        } catch  {            return nil        }    }    }////////////////////////////////////////////////////extension NSArray {        var toString:String! {        do {            let data = try JsONSerialization.data(withJsONObject: self,options: [])            let str = String(data:data,enCoding: String.EnCoding.utf8)!            return str        } catch  {            return ""        }     }}////////////////////////////////////////////////////extension NSDictionary {        var toString:String! {        do {            let data = try JsONSerialization.data(withJsONObject: self,enCoding: String.EnCoding.utf8)!            return str        } catch  {            return ""        }    }    }
