将obj c转换为swift HBVLinkedTextView

Question

我想查找用户点击的文字，我认为HBVLinkedTextView看起来不错，所以我想转换https://github.com/evilBird/HBVLinkedTextView/blob/master/HBVLinkedTextViewExample/HBVLinkedTextViewExample/ViewController.m 它迅速， 我是swift的新手，从未真正尝试过Objective-C，这就是我到目前为止做的事情（现在我只是用Hashtags测试这个＃）

func thedemo() {

        var textstr:NSString = "is @detected in a specified substring of the textview's text. You can set attributes and tap handling #blocks for #linked strings individually, by @passing in an array of strings, or with a @regular #expression."

        self.linkedText.text = textstr

        var error:NSError?
        var regex:NSRegularExpression = NSRegularExpression(pattern: "#(\\w+)", options: nil, error: nil)!
        var atr : NSDictionary = [NSForegroundColorAttributeName: UIColor.redColor()]
        var defaultAttributes : NSDictionary = [NSForegroundColorAttributeName: UIColor.greenColor()]


        self.linkedText.linkStringsWithRegEx(regex, defaultAttributes: defaultAttributes, highlightedAttributes: atr, tapHandler: self.exampleHandlerWithTitle("tag found"))

    }

我目前被困在

- (LinkedStringTapHandler)exampleHandlerWithTitle:(NSString *)title
{
    LinkedStringTapHandler exampleHandler = ^(NSString *linkedString) {

        UIAlertView *alert = [[UIAlertView alloc]initWithTitle:title
                                                       message:[NSString stringWithFormat:@"Handle tap in linked string '%@'",linkedString]
                                                      delegate:nil
                                             cancelButtonTitle:@"Dismiss"
                                             otherButtonTitles:nil, nil];
        [alert show];
    };

    return exampleHandler;
}

如何将此func转换为swift？
