swift delegate 和 block 使用

delegate使用

//自定义cell 代码

import UIKit
//声明代理协议
protocol btnClickDelegate {
    //代理方法
    func btnclickMethod(tag:Int)
}
class JRLoginTableViewCell: UITableViewCell {
    //代理属性
    public var delegate:btnClickDelegate?
    @IBOutlet weak var getCodeBtn: UIButton!
    @IBOutlet weak var codeTF: UITextField!
    @IBOutlet weak var phoneTF: UITextField!
    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
    }
 
    @IBAction func getCodeClick(_ sender: Any) {
//        print("获取验证码")
        if (delegate != nil) {
            delegate?.btnclickMethod(tag: 1)
        }
    }
    @IBAction func commitClick(_ sender: UIButton) {
//        print("马上开启")
        if (delegate != nil) {
            delegate?.btnclickMethod(tag: 2)
        }
    }
    @IBAction func textEidDidEnd(_ sender: UITextField) {
        print(sender.text as Any)
    }
    override func setSelected(_ selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)

        // Configure the view for the selected state
    }
}

viewController调用

//遵守协议
class JRMainViewController: JRRootViewController,btnClickDelegate,UITableViewDelegate,UITableViewDataSource {}

//设置代理
 let loginCell = tableView.dequeueReusableCell(withIdentifier: "JRLoginTableViewCell", for: indexPath)as! JRLoginTableViewCell
loginCell.selectionStyle = .none
loginCell.delegate = self ;
return loginCell

//实现协议方法
  //MARK: - btnClickDelegate
    func btnclickMethod(tag: Int) {
        print(tag)
        if tag == 1 {
            //获取验证码
            getPhoneCode(phoneStr: "123213")
        }else if tag == 2{
            //登录
        }
    }

block使用
//自定义cell 代码

import UIKit

class JRLoginTableViewCell: UITableViewCell {
    //代理属性
    @IBOutlet weak var getCodeBtn: UIButton!
    @IBOutlet weak var codeTF: UITextField!
    @IBOutlet weak var phoneTF: UITextField!
    //定义block
    typealias fucBlock = (String) ->()
    //创建block变量
    var blockproerty:fucBlock!
    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
        
    }

    @IBAction func textEidDidEnd(_ sender: UITextField) {
        print(sender.text as Any)
    }
    
    @IBAction func getCodeClick(_ sender: Any) {
//        print("获取验证码")
        //block调用
        if let _ = blockproerty{
            blockproerty("1212")
        }
    }
    @IBAction func commitClick(_ sender: UIButton) {
//        print("马上开启")
        
        if let _ = blockproerty{
            blockproerty("334344")
        }
    }
    override func setSelected(_ selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)

        // Configure the view for the selected state
    }
}

viewController调用

let loginCell = tableView.dequeueReusableCell(withIdentifier: "JRLoginTableViewCell", for: indexPath)as! JRLoginTableViewCell
loginCell.selectionStyle = .none
//block 回调
loginCell.blockproerty = {(backMsg) in
               print(backMsg);
}
return loginCell
