ios - switch case 错误中使用的枚举类型

Question

我在我的应用程序中编写了以下代码:

typedef enum{
    PasswordModeEnter = 1,
    PasswordModeSetNewPassword = 3,
    passwordModeVerify = 5,
    PasswordModeChange = 7,
    PasswordModeDisabled = 9
}PasswordModes;

然后我实例化了一个名为 PasswordMode 的对象。

- (id)initWithPasswordMode:(PasswordModes *)passwordMode nibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        self.PasswordMode = passwordMode;
    }
    return self;
}

我在编写以下代码时遇到了一个奇怪的错误:

switch (self.PasswordMode) {
        case PasswordModeChange:
            //do something
            break;

        case PasswordModeDisabled:
            //do something
            break;
        case PasswordModeEnter:
            //do something
            break;

        case PasswordModeSetNewPassword:
            //do something
            break;
        case passwordModeVerify:
            //do something
            break;

        default:
            break;
    }

出现以下错误:

statement requires expression of integer type.

问题是什么，我该如何解决？
