Convert Dictionary to JSON in Swift8个
我遇到了以下问题….
我的NSDictionary是这样的：
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,
原文链接：https://www.f2er.com/swift/319594.html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
