Ios 从数组的数组解析json

我的

json

数据位于第一个数组中，我的主类别数组名为“Response”，其中我的父类别数组名为“0”，其中我的子类别数组名为“0”，下面是我的

json

格式

{"Response":[{"menuname":"Jewellery","menuid":"1","0":[{"catname":"Rings","catid":"1","0":[{"scatname":"Engagement Rings","scatid":"4"},{"scatname":"Wedding Rings","scatid":"5"},{"scatname":"kk","scatid":"35"}]},{"catname":"Pendants","catid":"2","0":[{"scatname":"Office Wear","scatid":"8"}]},{"catname":"Bracelets","catid":"3","0":[{"scatname":"Studded","scatid":"9"}]},{"catname":"Earrings","catid":"6","0":[{"scatname":"Ethnic Jhumkas","scatid":"7"}]},{"catname":"Chain's","catid":"33","0":[]},{"catname":"Jewel","catid":"34","0":[]}]},{"menuname":"Collections","menuid":"2","0":[{"catname":"SOUND OF LOVE","catid":"15","0":[{"scatname":"LOVE BRACELET","scatid":"16"}]},{"catname":"COLORFUL AFFAIR","catid":"17","0":[{"scatname":"Passion ring","scatid":"18"}]},{"catname":"Evermore Collection","catid":"19","0":[]},{"catname":"BOARDROOM GLAM ","catid":"20","0":[]},{"catname":"ETERNAL GOLD","catid":"21","0":[]},{"catname":"FASHIONISTA COLLECTION","catid":"22","0":[]}]},{"menuname":"Gold Coin","menuid":"3","0":[{"catname":"SOUND OF LOVE","catid":"15","0":[{"scatname":"LOVE BRACELET","scatid":"16"}]},{"catname":"COLORFUL AFFAIR","catid":"17","0":[{"scatname":"Passion ring","scatid":"18"}]},{"catname":"Evermore Collection","catid":"19","0":[]},{"catname":"BOARDROOM GLAM ","catid":"20","0":[]},{"catname":"ETERNAL GOLD","catid":"21","0":[]},{"catname":"FASHIONISTA COLLECTION","catid":"22","0":[]}]},{"menuname":"OFF THE SHELF","menuid":"4","0":[{"catname":"testing from pixel","catid":"13","0":[]},{"catname":"New pixel","catid":"23","0":[]},{"catname":"Evermore Collection","catid":"19","0":[]},{"catname":"BOARDROOM GLAM ","catid":"20","0":[]},{"catname":"ETERNAL GOLD","catid":"21","0":[]},{"catname":"FASHIONISTA COLLECTION","catid":"22","0":[]}]}]}

我想在可扩展的tableview中显示，如下所示

Jewellery
  Rings
     Engagement Rings
     Wedding Rings
     kk
  Pendants
     Ofice Wear
Collections
  Sound Of  Love
     Love bracelet
  Colorful Affair
     Passion ring

下面是我在

NSDictionary*pJson；
NSMutableString*postStr=[nsmutablestringwithstring:kURL]；
[postStr appendString:[NSString stringWithFormat:@”？标记=%@&id=%@，kCategoryFilter，kPrecious]]；
[postStr设置字符串：[postStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]；

对于（inti=0；i我为您尝试了一些编码。遵循这些代码并自定义要添加到数组的位置和设置字典的位置

NSDictionary *jsonArray = [NSJSONSerialization JSONObjectWithData:responseData options: NSJSONReadingMutableContainers error: &err];

NSArray *array=[jsonArray objectForKey:@"Response"];

for (int i=0;i<[array count];i++)
{
    NSMutableDictionary *dict = [array objectAtIndex:i];
    NSMutableArray *arrayDictValue = [dict valueForKey:[NSString stringWithFormat:@"%d",0]];
    NSString *strMenuName = [NSString stringWithFormat:@"%@",[arrayDictValue valueForKey:@"menuname"]];
    NSString *strMenuID = [NSString stringWithFormat:@"%@",[arrayDictValue valueForKey:@"menuid"]];
    NSLog(@"The strMenuName is-%@",strMenuName);
    NSLog(@"The strMenuID is-%@",strMenuID);
    for (int j=0; j<[arrayDictValue count]; i++)
    {
        NSMutableDictionary *dictInside = [arrayDictValue objectAtIndex:j];
        NSArray *arrayInsideDict = [dictInside valueForKey:@"0"];
        for (int k =0; k<[arrayInsideDict count]; i++)
        {

            NSString *strCatName = [NSString stringWithFormat:@"%@",[[arrayInsideDict objectAtIndex:k ]valueForKey:@"catname"]];
            NSString *strCatID = [NSString stringWithFormat:@"%@",[[arrayInsideDict objectAtIndex:k ]valueForKey:@"catid"]];
            NSLog(@"The strCateName is-%@",strCatName);
            NSLog(@"The strCatID is-%@",strCatID);
            NSMutableDictionary *dictInArray = [[arrayInsideDict objectAtIndex:0] valueForKey:@"0"];
            NSString *strSCatName = [NSString stringWithFormat:@"%@",[dictInArray valueForKey:@"scatname"]];
            NSString *strSCatID = [NSString stringWithFormat:@"%@",[dictInArray valueForKey:@"scatid"]];
            NSLog(@"the strSCatName is - %@",strSCatName);
            NSLog(@"the strSCatID is - %@",strSCatID);

        }


    }


}

NSArray*数组=[jsonArray objectForKey:@“Response”]；
对于（int i=0；iLop是无限的，strCatName是（null）您检查得很好吗？首先在该dictionside之后打印arrayDictValue，arrayInsideDict.Check清楚。如果它没有任何对象，请快速告诉我。是的，它们有对象。那么您在哪里没有对象？
