将字典从 swift 发送到 objective-c class

Question

我在我的 swift 项目中实现了 CRToast。 CRToast 写在Objective-c。现在我想从 swift 文件调用 CRToast 的方法，我需要为此发送字典作为参数。字典中包含不同类型的值。怎样才能发送成功呢

func showToast(){

     let options: [NSObject : AnyObject] = [kCRToastTextKey: "Hello World!",           
        kCRToastTextAlignmentKey: NSTextAlignmet.Center,
        kCRToastBackgroundColorKey: UIColor.redColor(),
        kCRToastAnimationInTypeKey: CRToastAnimationType.Gravity,
        kCRToastAnimationOutTypeKey: CRToastAnimationType.Gravity,
        kCRToastAnimationInDirectionKey: CRToastAnimationDirection.Left,
        kCRToastAnimationOutDirectionKey: CRToastAnimationDirection.Right
]

    CRToastManager.showNotificationWithOptions(options, completionBlock: {() -> Void in
        NSLog("Completed")
    })
}

在 objective-c

中调用相同的函数

NSDictionary *options = @{
                      kCRToastTextKey : @"Hello World!",
                      kCRToastTextAlignmentKey : @(NSTextAlignmentCenter),
                      kCRToastBackgroundColorKey : [UIColor redColor],
                      kCRToastAnimationInTypeKey : @(CRToastAnimationTypeGravity),
                      kCRToastAnimationOutTypeKey : @(CRToastAnimationTypeGravity),
                      kCRToastAnimationInDirectionKey : @(CRToastAnimationDirectionLeft),
                      kCRToastAnimationOutDirectionKey : @(CRToastAnimationDirectionRight)
                      };
[CRToastManager showNotificationWithOptions:options
                        completionBlock:^{
                            NSLog(@"Completed");
                        }];

我需要调用的方法是showNotificationWithOptions

+ (void)showNotificationWithOptions:(NSDictionary*)options completionBlock:(void (^)(void))completion {
[self showNotificationWithOptions:options
                   apperanceBlock:nil
                  completionBlock:completion];

}

错误总是 get is can't cast to expected type [NSObject : AnyObject]!。有人可以指导我如何发送具有不同值的字典

您应该传递枚举原始值：

func showToast(){

        let options: [NSObject : AnyObject] = [kCRToastTextKey: "Hello World!",
            kCRToastTextAlignmentKey: NSTextAlignment.Center.rawValue,
            kCRToastBackgroundColorKey: UIColor.redColor(),
            kCRToastAnimationInTypeKey: CRToastAnimationType.Gravity.rawValue,
            kCRToastAnimationOutTypeKey: CRToastAnimationType.Gravity.rawValue,
            kCRToastAnimationInDirectionKey: CRToastAnimationDirection.Left.rawValue,
            kCRToastAnimationOutDirectionKey: CRToastAnimationDirection.Right.rawValue
        ]

        CRToastManager.showNotificationWithOptions(options, completionBlock: {() -> Void in
            NSLog("Completed")
        })
    }
