你好，怎么生成的字典怎么转json about mjextension

[yoimhere]

你好。。。用框架。。。看例子

在 2014-09-25 18:10:51，"leevin2014" [email protected] 写道：

使用JSONKit ，NSLog(@"%@", [dict JSONData]); NSLog(@"%@", [dict JSONString]); 结果都未null。

[NSJSONSerialization dataWithJSONObject:[NSDictionary dictionaryWithDictionary:dict] options:NSJSONWritingPrettyPrinted error:nil];
提示Invalid type in JSON write (__NSDate)

我生成字典后， NSDictionary *dict = [story keyValues];
不能转json

[CoderMJLee]

能给我看看你的Dict打印出来的结果么

是不是key带引号的原因转不了json

[CoderMJLee]

估计是NSDate和NSSet这种特殊的类型出问题了,这种类型是转不了JSON的,JSON仅仅支持NSString\NSNumber\NSArray\NSDictionary\基本数据类型等
