iOS 自定义控件

iOS控件创建有两种：

1。 用frame初始化view，然后用addSubview。init(frame:)

2。 用storyboard，然后载入。init?(coder:)

每一个UIView都有init?(coder:)

 

一、xib的形式

class OneLineTextField: UIView ,UITextFieldDelegate{
    
    //界面变量初始化
    override func awakeFromNib() {
        self.txtContent.delegate = self
    }
    
    @IBOutlet weak var txtContent: UITextField!

    @IBOutlet weak var line: UIView!
    
    
    func textFieldDidEndEditing(_ textField: UITextField) {
        ChangeLine()
    }
    
    func textFieldDidBeginEditing(_ textField: UITextField) {
        
        ChangeLine()
    }
    
    @discardableResult
    func ChangeLine()  {
        if self.txtContent.isFirstResponder
        {
            self.line.backgroundColor = UIHelper.mainColor
        }else
        {
            self.line.backgroundColor = UIColor.colorWithHex(hexValue: 0xE5E5E5)
        }
    }
}

　　

代码应用：主要是应用 addSubview

let nibContents = Bundle.main.loadNibNamed("OneLineTextField", owner: nil, options: nil)
        
        let vMobile:OneLineTextField = nibContents!.last as! OneLineTextField
        vMobile.frame = CGRect(x: 0, y: 0, width: self.viewForMobile.frame.width, height: self.viewForMobile.frame.height)
        
        vMobile.txtContent.placeholder = "输入您的手机号"
        
        self.viewForMobile.addSubview(vMobile)

　　

 

 

二、完全自定义

class YellowGrayButton: UIButton {

    
   @IBInspectable var cornerRadius = 6
    {
        didSet {
            self.layer.cornerRadius = CGFloat(cornerRadius)
        }
    }
    
   @IBInspectable var IsAllowClick:Bool = false
    {
        didSet{
            self.isEnabled = IsAllowClick
            if self.isEnabled
            {
                self.layer.backgroundColor = UIHelper.mainColor.cgColor
                self.backgroundColor = UIHelper.mainColor
            }else
            {
                self.layer.backgroundColor = UIColor.colorWithHex(hexValue: 0xDBDBDB).cgColor
                self.backgroundColor = UIColor.colorWithHex(hexValue: 0xDBDBDB)
            }
        }
    }
    
    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        self.layer.cornerRadius = 6
        self.clipsToBounds = true
        self.IsAllowClick = !self.IsAllowClick
        
        self.setTitleColor(UIColor.white, for: .normal)
        self.layer.backgroundColor = UIColor.colorWithHex(hexValue: 0xDBDBDB).cgColor
        self.backgroundColor = UIColor.colorWithHex(hexValue: 0xDBDBDB)

        
    }

}
