從NSDictionary保存NSDictionary中的數據

-3

這裏是我的JSON格式的數據，我已經解析並保存在名爲NSDictionary * dic的字典中。我有一個名爲dic1的NSDicitonary，我只想將數據從// 1存儲到//3我該怎麼做？請幫忙？從NSDictionary保存NSDictionary中的數據

//0 
[{ 
    "about": "Mother, actor, entrepreneur, fitness enthusiast and an eternal positive thinker", 
    "id": "238bb4ca-606d-4817-afad-78bee2898264", 
    "username": "Shilpa shetty kundr" 
} 
//1 
, { 
    "about": "Www.Nargisfakhri.com Instagram- @NargisFakhri Twitter- @NargisFakhri FaceBook- Nargis Fakhri ", 
    "id": "cda99c24-955a-4c58-a6a8-c811938df530", 
    "username": "Nargis Fakhri" 
} 
//2 
, { 
    "description": "Celebrating Black Friday in this lovely black cut out romper and floral accessories. I love black and i think it is the easiest thing to wear when i am in doubt. So a black romper solves my dilemma of what to wear when i am short of time to decide and outfit. When you wear black add some fun accessories to keep the outfit fun and lively.", 
    "id": "fa6d9bdf-eae3-4d6c-a668-9be94cfaf980", 
    "verb": "created this story on 25 October" 
}, 
//3 
{ 
    "description": "Today's outfit! #ootd Sheer shirts are always so sexy. Team it up with a bustier inside and it looks elegant and sexy at the same time. I wore my purple sheer shirt with an embellished maxi skirt and statement necklace. Sheer shirts looks fabulous with statement necklaces or layered chains.", 
    "id": "066f2bac-1fa8-44f8-b2b6-780df3324c71", 
    "verb": "created this story on 21 October" 
}]

這就是我所做的。

NSData* jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding]; 
id allKeys = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:nil]; 

userIDArray=[[NSMutableArray alloc]init]; 
for (int i=0; i<[allKeys count]; i++) { 
    NSDictionary *arrayResult = [allKeys objectAtIndex:i]; 
    if([arrayResult objectForKey:@"id"]!=NULL){ 
     NSString *id=[arrayResult objectForKey:@"id"]; 
     [userIDArray addObject:id]; 

    } 
}

我的觀點是allKeys整個數據被保存，而不是從// 0至3 //我只需要從// 02 //至03存放在一些字典數據保存完整的數據。

這是一個數組，而不是一本字典 – dan

@丹先生是有它的任何solluttion？ –

目前還不清楚你真正想做什麼。你應該用一些相關的代碼更新你的問題。顯示您擁有的字典以及您希望如何從其中獲取數據並將其放入其中。 – rmaddy

假設你意識到這是數組：

NSArray *a = [[NSArray alloc] init]; 
    NSMutableArray *a1 = [[NSMutableArray alloc] init]; 

    for(int i = 1; i < a.count; i++) { 
     [a1 addObject: a[i]]; 
    }

謝謝！終於明白了！ –

或[subarrayWithRange]更整齊 – Gruntcakes
