用于开关盒错误的枚举类型

Question

我在我的应用程序中写了以下代码:

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

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;
    }

我收到以下错误:

语句需要表达整数类型.

问题是什么,我该如何解决？

Answer 1

问题在于此

ProblemModes *

*应该删除.

Answer 2

PasswordModes只是一个枚举,你的init方法错误地指出它是一个指针.init方法签名应如下所示:

- (id)initWithPasswordMode:(PasswordModes)passwordMode nibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil;

您的财产应如下:

@property (nonatomic,assign) PasswordMode passwordMode;
