ios - 如何查找NSMutableDictionary中是否存在给定的字符串

我有一个NSString =@"KEY3";和NSMutableDictionary *AllValues ;如下所示。我只需要检查字符串是否是AllValues词典的元素之一

KEY1 {
    MLCAvailable = "test";
    MLCColorCode = "test2";
     NotesCount = "test3";
     },
KEY2 {
    MLCAvailable = "test";
    MLCColorCode = "test2";
     NotesCount = "test3";
     },
KEY3 {
    MLCAvailable = "test";
    MLCColorCode = "test2";
     NotesCount = "test3";
     },
KEY4 {
    MLCAvailable = "test";
    MLCColorCode = "test2";
     NotesCount = "test3";
     },

How should i find whether they KEY 3 is present in the given MutableDictionary ?
