Question

我正在尝试在我的swift项目中使用Objective-C框架。 https://github.com/cruffenach/CRToast

以下是示例代码

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

我的代码看起来像这样，它没有处理一些错误

@IBAction func btnClicked(sender: AnyObject) {
    var option:Dictionary <NSObject,AnyObject> = 
       [kCRToastTextKey : "Hello World!",
        kCRToastTextAlignmentKey : NSTextAlignment.Center,
        kCRToastBackgroundColorKey : UIColor.whiteColor(),
        kCRToastAnimationInTypeKey : CRToastAnimationType.Gravity,
        kCRToastAnimationOutTypeKey : CRToastAnimationType.Gravity,
        kCRToastAnimationInDirectionKey : CRToastAnimationDirection.Left,
        kCRToastAnimationOutDirectionKey : CRToastAnimationDirection.Right]

    CRToastManager.showNotificationWithOptions(option, completionBlock: nil)
}

但是当我保留'ColorKey'时，它会很好

CRToastManager.showNotificationWithOptions([kCRToastBackgroundColorKey : UIColor.whiteColor()], completionBlock: nil)

非常感谢你能解决这个问题

Answer 1

在swift中使用Objective-C框架时，需要添加桥接头文件。

请参阅this link有关桥接标题

的信息

我快速尝试了一下，问题在于试图将Swift的枚举值粘贴到词典中。如果你从每个枚举中获取rawValue，它对我有用：

var option: Dictionary<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(option, completionBlock: nil)

我在swift中调用了一个Objective-C框架，但似乎没有用
