如何使用多个objectForKey对NSMutableDictionaries的NSMutableArray进行排序(How to sort an NSMutableArray of NSMutableDictionaries using mutiple objectForKey)

 我有一个NSmutableArray中有几十个NSMutableDictionaries。 
 
 每个NSMutableDictionary看起来像这样 
 
insComp = F;
insFlow = "suVE";
inID = "SJF42B";
ID = 10000038;
 
 然后我想知道我是如何对几个NSDictionary键进行分类的。 为每个对象实例。 
 
 insComp> inID> ID 
 
 例如，不使用相同的键或值 
 
-- obj1
var1 = A
var2 = A

-- obj2
var1 = A
var2 = B

-- obj3
var1 = B
var2 = A

-- obj4
var1 = C
var2 = A
 
 所以这将首先通过var1进行排序，然后对每个var1-var2进行排序，依此类推。 我认为它被称为树排序？ 
 
 任何帮助将不胜感激。 

I have a NSmutableArray with dozens of NSMutableDictionaries in it.
 
Each NSMutableDictionary looks something like this
 
insComp = F;
insFlow = "suVE";
inID = "SJF42B";
ID = 10000038;
 
I would then like to know how I sort acending values by several of the NSDictionary keys. for each object instance.
 
insComp > inID > ID
 
for example, not using same keys or values
 
-- obj1
var1 = A
var2 = A

-- obj2
var1 = A
var2 = B

-- obj3
var1 = B
var2 = A

-- obj4
var1 = C
var2 = A
 
So that would be sorting first by var1 then every var1-var2 is sorted and so on. I think its refered to as a tree sort?
 
any help would be greatly appreciated.
