Convert Dictionary to JSON in Swift8个

我遇到了以下问题….
我的NSDictionary是这样的:
var dic : NSDictionary = [ "level" : [ ["column" : 0,"down" : 0,"left" : 0,"right" : 0,"row" : 0,"up" : 0],["column" : 1,["column" : 2,["column" : 0,"row" : 1,"up" : 0] ] ]
但如果我打印这个,
print(dic); or print(“\(dic)”);
输出是这样的:
{ level = ( { column = 0; down = 0; left = 0; right = 0; row = 0; up = 0; },{ column = 1; down = 0; left = 0; right = 0; row = 0; up = 0; },{ column = 2; down = 0; left = 0; right = 0; row = 0; up = 0; },{ column = 0; down = 0; left = 0; right = 0; row = 1; up = 0; },{ column = 1; down = 0; left = 0; right = 0; row = 1; up = 0; },{ column = 2; down = 0; left = 0; right = 0; row = 1; up = 0; } ); }
我怎样才能得到精确的Json字符串?
在swift中,xcode?
无需实现这种复杂的逻辑,
你可以简单地做到这一点
var jsonData: NSData = NSJSONSerialization.dataWithJSONObject(dictionary,options: NSJSONWritingOptions.PrettyPrinted,error: &error)! if error == nil { return NSString(data: jsonData,encoding: NSUTF8StringEncoding)! as String }
如果你想用API发送它到服务器,甚至不需要将它转换为String
