我知道UITextView默认可以检测到URL,但是我怎样才能检测到#tatata(#)？

它不需要在键入时检测主题标签,但随后viewDidLoad文本设置在UITextView,所以我想检测主题标签作为颜色或什么.

我一直在使用ActiveLabel,但这只是用于UILabel,我需要具有的滚动功能UITextView.

在我的应用程序中,我正在使用ActiveLabelfram Github.

在这种情况下,我的标签不会显示UILabel中间的文本.如果我使用普通的UILabel它可以正常工作,但是当它设置为ActiveLabel时,它会像这样.

我认为这是以某种方式使用对齐的代码:

/// add line break mode
private func addLineBreak(attrString: NSAttributedString) -> NSMutableAttributedString {
    let mutAttrString = NSMutableAttributedString(attributedString: attrString)

    var range = NSRange(location: 0, length: 0)
    var attributes = mutAttrString.attributesAtIndex(0, effectiveRange: &range)

    let paragraphStyle = attributes[NSParagraphStyleAttributeName] as? NSMutableParagraphStyle ?? NSMutableParagraphStyle()
    paragraphStyle.lineBreakMode = NSLineBreakMode.ByWordWrapping
    if let lineSpacing = lineSpacing {
        paragraphStyle.lineSpacing = CGFloat(lineSpacing)
    }

    attributes[NSParagraphStyleAttributeName] = paragraphStyle
    mutAttrString.setAttributes(attributes, range: range)

    return mutAttrString
}

ActiveLabel.swift

ActiveType.swift

任何想法如何我可以在中间这样做:

我现在使用此代码在按钮水龙头上旋转瓶子:

@IBAction func spinButton(sender: AnyObject) {
        let rotateView = CABasicAnimation()
        let randonAngle = arc4random_uniform(360) + 720
        rotateView.fromValue = 0
        rotateView.toValue = Float(randonAngle) * Float(M_PI) / 180.0
        rotateView.duration = 3
        rotateView.delegate = self
        rotateView.repeatCount = 0
        rotateView.removedOnCompletion = false
        rotateView.fillMode = kCAFillModeForwards
        rotateView.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseOut)
        bottleImageView.layer.addAnimation(rotateView, forKey: "transform.rotation.z")
    }

但是如何使用手势旋转按钮？因此,我移动手指越硬/越快,瓶子旋转的速度就越快

我试图调整单元格高度调整大小以适应UILabel文本,但它不工作..

var mySize = CGFloat()
    func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
        let cell = collectionView.dequeueReusableCellWithReuseIdentifier("cell", forIndexPath: indexPath) as! cellView

        cell.myLabel.text = self.items[indexPath.item]
        cell.myLabel.bounds.size.height = self.mySize

        cell.backgroundColor = UIColor.yellowColor()

        return cell
    }

    func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
        // handle tap events
        print("You selected cell #\(indexPath.item)!")
    }

    func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize {

        func heightForLabel(text:String, font:UIFont, width:CGFloat) -> CGFloat
        {
            let label:UILabel = UILabel(frame: CGRectMake(0, 0, width, CGFloat.max))
            label.numberOfLines = 0 …

所以,目前我用它来压缩视频:

func compressVideo(inputURL: NSURL, outputURL: NSURL, handler:(session: AVAssetExportSession)-> Void)
    {
        let urlAsset = AVURLAsset(URL: inputURL, options: nil)

        let exportSession = AVAssetExportSession(asset: urlAsset, presetName: AVAssetExportPresetMediumQuality)

        exportSession!.outputURL = outputURL

        exportSession!.outputFileType = AVFileTypeQuickTimeMovie

        exportSession!.shouldOptimizeForNetworkUse = true

        exportSession!.exportAsynchronouslyWithCompletionHandler { () -> Void in

            handler(session: exportSession!)
        }

    }

当我在2秒内录制视频时,大小为4.3 MB,当我在6秒内录制视频时,文件大小为9,3 MB.

任何减小尺寸的提示？

我如何以编程方式调整字体大小,使文本适合UILabel,而不调整大小UILabel？

我已经设定了这个:

imageCell?.imageText.adjustsFontSizeToFitWidth = true

同样在我设置的故事板中Line Breaks: Word Wrap,Autoshrink: Minimum Font Size: 1和Lines: 0.

这就是标签的样子:

这是整个标签文字:

Æ❤️❤️mzbdjdis#Svsuzi.#vdb#%<<,#hs.ClcldbsD.Cmcøclco

但是整个文本仍没有在标签中显示.我没有在我的应用程序中使用AutoLayout.有什么建议？

如何设置残留在人物UILabel的UITextView？

我已经为UITextField，但同样的代码不起作用..

这是我尝试过的：

func textView(textView: UITextView, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool
 {
        if string == ""
        {
            if plainTextView.text!.characters.count == 0
            {
                charCount = 0
                countLabel.text = String(format: "%i Characters Left", maxLength - charCount)
                return false
            }
            charCount = (plainTextView.text!.characters.count - 1)
            countLabel.text = String(format: "%i Characters Left", maxLength - charCount)
            return true
        }
        else
        {
            charCount = (plainTextView.text!.characters.count + 1)
            countLabel.text = String(format: "%i Characters Left", maxLength - charCount)

            if …

尝试归档我的应用程序时出现此错误:

我不明白,因为我没有在我的应用程序中使用LaunchImage.

我的设置如下所示:

关于我在这里可以做什么的任何建议？

所以我正在创建一款纸牌游戏Ring of Fire.我存储了这样的图像:

var picture:[UIImage] = [
        UIImage(named: "Card2")!,
        UIImage(named: "Card3")!,
        UIImage(named: "Card4")!,
        UIImage(named: "Card5")!,
        UIImage(named: "Card6")!,
        UIImage(named: "Card7")!,
        UIImage(named: "Card8")!,
        UIImage(named: "Card9")!,
        UIImage(named: "Card10")!,
        UIImage(named: "CardJack")!,
        UIImage(named: "CardQueen")!,
        UIImage(named: "CardKing")!,
        UIImage(named: "CardAce")!,
        ]

每张卡片都有当前卡片下方显示的文字:

var name:String = ""
