  [connection release];

   NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
   self.responseData = nil;

   dict = [responseString JSONValue];

            NSMutableArray *array = [NSMutableArray array];
           for (NSString *key in [dict allKeys])
          {

               array = [dict objectForKey:key];
           // array return float values but

Your app is crashing because you are adding data to NSArray , this is static array, you can not add value at run time, so just Make NSMutableArray and add your data in NSMutableArray.

Your code is broken in a couple of ways.

This line assigns the array pointer to the object in the dictionary:

array = [dict objectForKey:key];

Then you are trying to add the array to itself, which does not make sense. But worse, since array does no longer point to your NSMutableArray you cannot even call that method.

[array addObject:array ];

You probably wanted to do something like this:

for (NSString *key in [dict allKeys])
{  
     id value = [dict objectForKey:key];              
     [array addObject:value];     
}
