parsing一个Json表到一个NSMutableArray

目前我直接通过本地目标C代码填写我的数组：

Datas *pan1 = [[Datas alloc] initWithTitle:@"My array 1" title:@"Shakespeare's Book" location:@"London"]; Datas *pan2 = [[Datas alloc] initWithTitle:@"My array 2" title:@"Moliere's Book" location:@"London"]; NSMutableArray *datasListe = [NSMutableArray arrayWithObjects:pan1, pan2, nil]; 

但是我想通过这个Json列表来填充这个NSMutableArray：

 { "myIndex" : [ { "name":"My array 1", "title": "Shakespeare's Book", "location": "London" }, { "name":"My Array 2", "title": "Moliere's Book", "location": "Paris" } ] } 

任何人有想法？ 非常感谢！

这json数据可以像这样很容易parsing。

 NSError *e; NSArray *dic= [NSJSONSerialization JSONObjectWithData: jsondata options: NSJSONReadingMutableContainers error: &e]; NSMutableArray *datasListe = [[NSMutableArray alloc] init]; NSMutableArray *data = [dic objectForKey:@"myIndex"]; //Now you have array of dictionaries for(NSDictionary *dataDic in data){ NSString *name = [dataDic objectForkey:@"name"]; NSString *title = [dataDic objectForKey@"title"]; NSString *location = [dataDic objectForKey@"location"]; Datas *pan= [[Datas alloc] initWithTitle:name title:title location:location]; [dataList addObject:pan]; }

 NSDictionary *firstDictionary = [NSDictionary dictionaryWithObjectsAndKeys: @"Raja", @"name", @"Developer", @"title", @"USA", @"location", nil]; NSDictionary *secondDictionary = [NSDictionary dictionaryWithObjectsAndKeys: @"Deepika", @"name", @"Engieer", @"title", @"USA", @"location", nil]; NSMutableArray * arr = [[NSMutableArray alloc] init]; [arr addObject:firstDictionary]; [arr addObject:secondDictionary]; NSData *jsonData = [NSJSONSerialization dataWithJSONObject:arr options:NSJSONWritingPrettyPrinted error:&error]; NSString *jsonString = [[NSString alloc] initWithData:jsonData2 encoding:NSUTF8StringEncoding]; NSLog(@"jsonArray as string:\n%@", jsonString);
