Swift Bridge 和 Closure Band SDK

Question

我在尝试编译这段代码时遇到了这个错误。有人可以帮我调试吗？:

Cannot convert value of type '(NSError!) throws -> Void' to expected argument type '((NSError!) -> Void)!'

标题:

@class MSBTile;

@protocol MSBTileManagerProtocol <NSObject>

- (void)addTile:(MSBTile *)tile completionHandler:(void(^)(NSError *error))completionHandler;

@end

View Controller :

client.tileManager.addTile(tile, completionHandler: {
            (error: NSError!) -> Void in
            if error == nil || MSBErrorType(rawValue: error.code) == MSBErrorType.TileAlreadyExist {
                self.output("Creating page...")

                ...
                })
            } else {
                self.output(error.localizedDescription)
            }
        })

我为将来遇到此问题的任何人找到了解决方法。事实证明，其中两个函数调用也是可抛出的，因此我不得不将它们包装在 try catch block 中，如下所示:

 let pageTextBlock: AnyObject
                    do {
                        pageTextBlock = try MSBPageTextBlockData(elementId: 10, text: "TextButton Sample")
                    }catch _ {
                        pageTextBlock = ""
                    }

                    let pageButtonBlock: AnyObject
                    do {
                        pageButtonBlock = try MSBPageTextButtonData(elementId: 11, text: "Press Me")
                    }catch _ {
                        pageButtonBlock = ""
                    }

免责声明:我对 Swift 还是个新手，所以这可能不是最好的解决方案。
