这里是我的JSON格式的数据,我已经解析并保存在名为NSDictionary * dic的字典中。我有一个名为dic1的NSDicitonary,我只想将数据从// 1存储到//3我该怎么做?请帮忙?从NSDictionary保存NSDictionary中的数据

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.",

这就是我所做的。
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];
}
}
我的观点是allKeys整个数据被保存,而不是从// 0至3 //我只需要从// 02 //至03存放在一些字典数据保存完整的数据。
这是一个数组,而不是一本字典 – dan
@丹先生是有它的任何solluttion? –
目前还不清楚你真正想做什么。你应该用一些相关的代码更新你的问题。显示您拥有的字典以及您希望如何从其中获取数据并将其放入其中。 – rmaddy
