ios - 当某些键动态更改时如何从字典中获取值

Question

我有一个包含 20 个对象的可变数组。每个对象都有给定的格式

{

 "NONE-NONE-ABCD-RECD" =     {
  Count =         
        {
              bird = "10";
              animal = "4";
        };

  Type = "NONE-NONE-ABCD-RECD";
};

} 

键值NONE-NONE-ABCD-RECD对于不同的对象会有所不同。有时会变成NONE-NONE-NONE-NONE或ABCD-PQWE -MNBW-POWE等我需要找到每个对象的鸟和动物。当键改变时我怎样才能得到计数。

试试这个，

NSArray *allKeys = [elementDict allKeys]; //elementDict array object
if ([allKeys count] > 0) {
    NSDictionary *objectDict = [elementDict objectForKey:[allKeys objectAtIndex:0]];
    NSDictionary *countDict = [objectDict objectForKey:@"Count"];
    //from countDict you can access values
    NSString *bird = [countDict valueForKey:@"bird"];
    NSString *animal = [countDict valueForKey:@"animal"];
}
