如何使用jsonkit将中的数据数组转换为json

 [hi] [;]

您需要使用以下代码。

NSDictionary *dict = [myJsonString JSONValue];

如果它不起作用，那么使用以下

// 
// we begin with our string in json format
//
NSString *jsonString = [[NSString alloc] initWithString:@"{"1":"1: Rossy Robinson - $25","2":"7: Davey Ambrose - $25","3":"14: Ross Robinson - $25"}"];
//
// convert the json string to an NSMutableDictionary
//
NSError *e;
NSMutableDictionary *JSONdic = [NSJSONSerialization JSONObjectWithData: [jsonString dataUsingEncoding: NSUTF8StringEncoding] options: NSJSONReadingMutableContainers error: &e];
//
// change a value and add a new value in the dict
//
NSLog(@"before: object for key 1 is: %@", [JSONdic objectForKey:@"1"]);
[JSONdic setObject:@"xxx" forKey:@"1"];
[JSONdic setObject:@"Phil McQuitty" forKey:@"2"];
//
//convert dictionary object to json data
//
NSData* jsonData = [NSJSONSerialization dataWithJSONObject:JSONdic options:NSJSONWritingPrettyPrinted error:&e];
//
// convert the json data back to a string
//
NSString *jsonText = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
//
// print out the final results
//
NSLog(@"back to string: %@", jsonText);
