自定义UIView类 - 斯威夫特

Question

我已经建立了一个视图，从底部出现，并在一段时间后隐藏，它运作良好，但我想使它在UIView类作为模式，我看着互联网，但我不能'不知道该怎么做。

snake = UIView(frame: CGRect(x: 0 , y: self.view.frame.size.height-66, width: self.view.frame.size.width, height: 66)) 
snake.backgroundColor = UIColor(red: 50/255, green: 50/255, blue: 50/255, alpha: 1.0) 


let label = UILabel(frame: CGRect(x: 12, y: 8, width: snake.frame.size.width-90, height: 50)) 
label.text = "Connection error please try again later!!" 
label.textColor = UIColor.whiteColor() 
label.numberOfLines = 0 
label.font = UIFont.systemFontOfSize(14) 
snake.addSubview(label) 

let button = UIButton(frame: CGRect(x: snake.frame.size.width-87, y: 8, width: 86, height: 50)) 
button.setTitle("OK", forState: UIControlState.Normal) 
button.setTitleColor(UIColor(red: 76/255, green: 175/255, blue: 80/255, alpha: 1.0), forState: UIControlState.Normal) 
button.addTarget(self, action: "hideSnackBar:", forControlEvents: UIControlEvents.TouchUpInside) 
snake.addSubview(button) 
self.view.addSubview(snake) 

如何启动这一类，我不知道，我与它的框架创建视图编程，我需要为例子或标签按钮设置属性和创建任何类的观点。

class snake: UIView { 


    override init (frame : CGRect) { 
     super.init(frame : frame) 

    } 

    convenience init() { 
     self.init(frame:CGRect.zero) 
    } 

    required init(coder aDecoder: NSCoder) { 
     fatalError("This class does not support NSCoding") 
    } 

}

代码：

var label:UILabel! 
var button:UIButton! 

override init (frame : CGRect) { 
    super.init(frame : frame) 
    self.backgroundColor = UIColor(red: 50/255, green: 50/255, blue: 50/255, alpha: 1.0) 


    label = UILabel(frame: CGRect(x: 12, y: 8, width: self.frame.size.width-90, height: 50)) 
    label.text = "Connection error please try again later!!" 
    label.textColor = UIColor.whiteColor() 
    label.numberOfLines = 0 
    label.font = UIFont.systemFontOfSize(14) 
    self.addSubview(label) 

    button = UIButton(frame: CGRect(x: self.frame.size.width-87, y: 8, width: 86, height: 50)) 
    button.setTitle("OK", forState: UIControlState.Normal) 
    button.setTitleColor(UIColor(red: 76/255, green: 175/255, blue: 80/255, alpha: 1.0), forState: UIControlState.Normal) 
    button.addTarget(self, action: "hideSnackBar:", forControlEvents: UIControlEvents.TouchUpInside) 
    self.addSubview(button) 
} 

，并使用它：

let snakeView = snake(frame: CGRectMake(0 ,self.view.frame.size.height-66, self.view.frame.size.width, 66))) 

和snakeview组数据：

snakeView.label.text = "hello" 

但通常我将创建一个函数来更新数据查看：

func updateData(title:String){ 
    self.label.text = title 
} 

，并调用它，当需要：

snake.updateData("hello") 

P/S：如果您使用的厦门国际银行，你必须实现awakeFromNib，而不是初始化的。并建立与厦门国际银行蛇（记住厦门国际银行集标识符：“snakeView”）：

let snakeView = NSBundle.mainBundle().loadNibNamed("snakeView", owner: nil, options: nil)[0] as snakeView
