Question

我有一个JSON对象，它有一个像这样的键值对

"AttachedDocument": "[{\"DocumentId\":354,\"DocumentName\":\"Screenshot_2016-04-15-00-35-11.png\",\"DocumentType\":\"image/png\"}]"

此值以字符串形式出现。如何将其转换为NSArray

实际上，您获得%>%作为回复，因此您可以将其转换为josn string之类的内容，

josn object

此处NSString *yourString = @"[{\"DocumentId\":354,\"DocumentName\":\"Screenshot_2016-04-15-00-35-11.png\",\"DocumentType\":\"image/png\"}]"; NSError *error; NSData *data = [yourString dataUsingEncoding:NSUTF8StringEncoding]; NSArray *jsonObject = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&error]; NSLog(@"json object : %@",jsonObject);表示yourString键的对象！
