  您应该创建一个包含这两个元素的 UIView 子类 . 创建包含这些实体的相应 .xib 文件或在代码中实现这些实体 . 您还可以实现 touchesBegan ，以便此视图可以像按钮一样操作或添加按钮而不是文本标签，并实现每次按下按钮时触发的协议 . 我必须和他们一起玩才能让他们做得恰到好处 .

  class UICoolButton: UIView {
  
      var labelText: NSString?
      var circledNumber: Int?
      var circleSubview: UIView?
  
      init(frame: CGRect, labelText: NSString, circledNumber: Int) {
          super.init(frame: frame);
          self.labelText = labelText;
          self.circledNumber = circledNumber;
          self.layer.cornerRadius = frame.height/3
          self.clipsToBounds = true
          addCircledNumber()
          addTextLabel(labelText)
      }
  
      func setColors(numberColor:UIColor, backgroundColor: UIColor) {
          self.backgroundColor = backgroundColor
          self.circleSubview?.backgroundColor = numberColor
      }
  
      override init(frame: CGRect) {
          super.init(frame: frame);
      }
  
      required init?(coder aDecoder: NSCoder) {
          super.init(coder: aDecoder);
      }
  
      func addTextLabel(text: NSString) {
          let origin = CGPoint(x:self.frame.width * 0.4, y:self.frame.height/10)
          let size = CGSize(width: self.frame.width/2, height: self.frame.height * 0.8)
          let rect = CGRect(origin: origin, size: size)
          let label = UILabel(frame: rect)
          let attributes: [String : AnyObject] = [NSFontAttributeName : UIFont(name: "Verdana", size: 16.0)!,
          NSForegroundColorAttributeName : UIColor.whiteColor()]
  
          label.attributedText = NSAttributedString(string: text, attributes: attributes)
  
          self.addSubview(label)
      }
  
      override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
  
      }
  
      func addCircledNumber() {
          let height = self.frame.height * 0.4;
          let circleDimensions = CGSize(width: height , height:height)
          let origin = CGPointMake(self.frame.width * 0.15, self.frame.height - self.frame.height/1.5)
          let circleSubview = UIView(frame: CGRect(origin: origin, size: circleDimensions))
          circleSubview.layer.cornerRadius = height/2;
          circleSubview.backgroundColor = UIColor.darkGrayColor()
  
          let labelHeight = height * 0.8;
  
          let xPosition = circleSubview.bounds.origin.x + 3
          let yPosition = circleSubview.bounds.origin.y + 2
  
          let labelOrigin =  CGPoint(x: xPosition, y: yPosition)
          let labelRect = CGRect(origin: labelOrigin, size: CGSize(width: labelHeight, height: labelHeight))
          let numberLabel = UILabel(frame: labelRect);
          numberLabel.textAlignment = NSTextAlignment.Center
  
          let numberAsString = NSString(format: "%i", circledNumber!) as String
          let attributes: [String : AnyObject] = [NSFontAttributeName : UIFont(name: "Verdana", size: 16.0)!,
          NSForegroundColorAttributeName : UIColor.whiteColor()]
          numberLabel.attributedText = NSAttributedString(string: numberAsString, attributes: attributes)
          circleSubview.addSubview(numberLabel);
          self.circleSubview = circleSubview
          self.addSubview(circleSubview)
      }
  

  然后在View Controller中，使用我写的initilizer：

  func addCoolButton() {
      let rect = CGRect() //choose the frame for your button here
      let button = UICoolButton(frame: rect, labelText: "Example", circledNumber: 10);
  
      let backgroundColor = UIColor(red: 243/255.0 , green: 93/255.0, blue: 118/255.0, alpha: 1.0)
      let numberColor = UIColor(red: 252/255.0, green: 118.0/255.0, blue: 135/255.0, alpha: 1.0)
      button.setColors(numberColor, backgroundColor: backgroundColor)
  
      self.view.addSubview(button)
  }

  我用autolayout做了一些类似于你的目的的东西

  

  代码在这里：

  @interface ViewController ()
  
  @property (weak, nonatomic) IBOutlet UIView *content;
  @property (weak, nonatomic) IBOutlet UILabel *label;
  
  @end
  
  @implementation ViewController
  
  - (void)viewDidLoad {
      [super viewDidLoad];
      self.content.layer.cornerRadius = MIN(self.content.bounds.size.width, self.content.bounds.size.height)/2;
      self.content.clipsToBounds = true;
  
  }
  
  @end
  

  数字的结果是1234：

  

  数字为1的结果：
