用键和对象枚举NSDictionary，PHP样式
问题描述：
我知道您可以使用 NSEnumerator 枚举 NSMutableDictionary 的键或值。可以一起做吗？我正在寻找类似于PHP foreach 枚举器的东西，例如：
I know you can Enumerate the keys or values of NSMutableDictionary using NSEnumerator. Is it possible to do both together? I'm looking for something similar to the PHP foreach enumerator like:
foreach ($dictionary as $key => $value);
答
也许看看NSDictionary的方法：
Perhaps look into NSDictionary's method:
enumerateKeysAndObjectsUsingBlock:(void (^)(id key, id obj, BOOL *stop))
