比较2个阵列无法正常工作

Question

所以我正在制作游戏，我正在尝试实例化一个组合系统。我随机创建带有移动的数组，然后检查用户是否移动匹配它们。唯一的问题是[array1 isEqualToArray：array2]即使它们相同也不会返回true。这是日志和代码：

比较代码：

if([self.possibleCombo count] == IS_COMBO_LENGTH){
        for (NSArray *checkCombo in self.combos){
            NSLog(@"Check Combo: %@", checkCombo);
            NSLog(@"User Move: %@", self.possibleCombo);
            if([self.possibleCombo isEqualToArray:checkCombo]){
                NSLog(@"match");
                multiplier *= 2;
            } else {
                NSLog(@"no match");
                multiplier = 1;
            }
        }
        [self.possibleCombo removeAllObjects];
    }
