该项目主要介绍了oc与swift之间、swift内部几种常见的传值方式(属性传值代码块传值、代理传值、通知)

如果oc与swift之间的桥接有疑问请参考:OC与swift桥接互调

项目介绍

  • 1、swift之间的页面跳转与返回
  • 2、oc监听swift推送的通知
  • 3、swift内部推送接收的通知
  • 4、oc调用swift的代理方法
  • 5、swift调用oc代码块
  • 6、oc对swift的属性传值、方法调用、代码块调用
  • 7、swift对oc的属性传值、方法调用、代码块调用
  • 8、swift之间的传值

1、swift之间的页面跳转与返回

1、present方式跳转

@objc func btnAction(_ sender:UIButton){
        let subVC  = SubVC();
        self.present(subVC, animated: true) {
            NSLog("������:%@", subVC);
        };
        NSLog("������:%@____%@",sender,self);
    }

2、返回

self.dismiss(animated: true) {
                NSLog("返回");
            };

2、oc监听swift推送的通知:

  • swift发送通知
func postNotifition(){
        NotificationCenter.default.post(name: NSNotification.Name(rawValue: "XMNotification"), object: "通知方法");
    }
  • oc接收通知
-(void)addNotification{
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(notiAction:) name:@"XMNotification" object:nil];
}

-(void)notiAction:(NSNotification *)sender{
    NSLog(@"oc:%@",sender.object);
}

-(void)removeNotification{
    [[NSNotificationCenter defaultCenter] removeObserver:self name:@"XMNotification" object:nil];
}

3、swift内部推送接收的通知:

func postNotifition(){
        NotificationCenter.default.post(name: NSNotification.Name(rawValue: "XMNotification"), object: "通知方法");
    }

    @objc func addNotification(){
        NotificationCenter.default.addObserver(self, selector: #selector(notificationAction(_:)), name: NSNotification.Name(rawValue: "XMNotification"), object: nil);
    }
    @objc func removeNotifition() {
        NotificationCenter.default.removeObserver(self);
    }

    @objc private func notificationAction(_ noti : Notification){
        let str:String = noti.object as! String;
        print("swift:" + str);
    }

4、oc调用swift的代理方法:

  • 编辑协议方
///1、编辑协议
@objc(FourVCDelegate)
protocol FourVCDelegate {
    func backSuperVC(str:String)
}

///2、定义协议对象
@objc var myDelegate:FourVCDelegate?;

///3、调用协议
let str:String = "代理方法"
self.myDelegate?.backSuperVC(str: str);
  • 签署协议方
///1、调用协议
@interface FirVC ()<FourVCDelegate>

///2、签署协议
-(SecVC *)seVc{
    if (!_seVc) {
        _seVc = [SecVC new];
        _seVc.myDelegate = self;
    }
    return _seVc;
}

///3、协议实现
-(void)backSuperVCWithStr:(NSString *)str{
    NSLog(@"%@", str);
}

5、swift调用oc代码块

  • oc文件类
///代码块定义
@property(nonatomic,strong)void (^thiBlock)(NSString *str);

///代码块实现
!self.thiBlock?:self.thiBlock(@"swift调用oc代码块");
  • swift文件类
let vc  = ThiVC();
///代码块调用
vc.thiBlock = {(str) -> () in
    print("代码块方法");
}

self.present(vc, animated: true, completion: {

});

6、oc对swift的属性传值、方法调用、代码块调用

  • swift方法类
import UIKit

class FourVC: UIViewController {

    ///数组
    @objc var arr0:NSArray = NSArray()

    ///无参数无返回值
    @objc func swMethod0(){
        print("无参数无返回值");
    }
    ///有参数无返回值
    @objc func swMethod1(str: String)  {
        print("有参数无返回值:\(str)");
    }
    ///有参数有返回值
    @objc func swMethod2(str: String) -> (String){
        return "有参数有返回值:" + str;
    }

    /// mark - 代码块
    ///无返回参数
    @objc func bkBlock0(response:() -> ()){
        response();
    }
    ///返回一个字符串参数
    @objc func bkBlock1(response:(_ res : String) -> ()) {
        response("返回一个字符串参数");
    }
    ///返回多个任意类型参数
    @objc func bkBlock_2_(response:(_ res : Any,_ res1 : Any) -> ()) {
        response(self.arr0, "无参数,返回多个任意类型参数:");
    }
    ///传入多个参数 并返回多个任意类型的参数
    @objc func bkBlock3(p1:Any,p2:Any,p3:Any,res:(_ res0 : Any ,_ res1 : Any ,_ res2:Any,_ res3:Any) -> ()) {
        res("传入多个参数 并返回多个任意类型的参数:\n",p1, p2, p3);
    }
    ///Block带返回值
    @objc func bkBlock4(res:() -> ()) -> (String){
        res();
        return "Block带返回值"
    }


    //定义block
    typealias fucBlock = (_ backMsg : String?) ->()
    func bkBlock4(cmdStr:String?,blockProperty:fucBlock){
        blockProperty("backMsg---by block inside func")
    }

    override func viewDidLoad() {
        super.viewDidLoad()
        self.view.backgroundColor = UIColor.yellow;
        print("属性传值结果:",self.arr0[0],self.arr0[1],arr0[2]);
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        self.dismiss(animated: true) {

        };
    }
}
  • oc方法类:
FourVC *vc = [FourVC new];
    // --- 属性传值 ---
    vc.arr0 = @[@"可以",@"可以",@"可以"];

    /// ------ 方法调用 -----

    //无参数无返回值
    [vc swMethod0];
    //有参数无返回值
    [vc swMethod1WithStr:@"dasda"];
    //有参数有返回值
    NSString *str = [vc swMethod2WithStr:@"sdfasda"];
    NSLog(@"%@",str);

    /// ------ 代码块调用 -----

    [vc bkBlock0WithResponse:^{
        NSLog(@"无返回数据代码块");
    }];

    //有一个返回值
    [vc bkBlock1WithResponse:^(NSString * str) {
        NSLog(@"%@", str);
    }];

    //有两个返回值
    [vc bkBlock_2_WithResponse:^(id str, id str1) {
        NSLog(@"%@\n%@",str1,str);
    }];

    //有参数有返回值
    [vc bkBlock3WithP1:@"ds" p2:@"dsa" p3:@"das" res:^(id p0,id p1, id p2, id p3) {
        NSLog(@"%@\n%@\n%@\n%@",p0,p1,p2,p3);
    }];

    [self presentViewController:vc animated:YES completion:^{

    }];

7、swift对oc的属性传值、方法调用、代码块调用

  • xxx.h文件
@interface OcVC : UIViewController
///代码块
@property(nonatomic,strong)void (^clickBlock)(void);
///字符串
@property(nonatomic,copy)NSString *titStr;
///方法
-(void)testAction;
@end
  • xxx.m文件
- (void)viewDidLoad {
    [super viewDidLoad];
    NSLog(@"%@",self.titStr);
    !self.clickBlock?:self.clickBlock();
}

-(void)testAction{
    NSLog(@"调用方法");
}
  • xxx.swift文件
let sub  = OcVC();
//属性传值
sub.titStr = "属性传值";
//方法调用
sub.testAction();

//代码块调用
sub.clickBlock = { () -> () in
     print("不带参数代码块")
};

sub.clickBlock();
self.present(sub, animated: true, completion: {

});

8、swift之间的传值

func jumpToNextVC(){
        ///mark - =============
        let foVC =  FourVC()

        let dic:NSDictionary = ["key":1,"key1":2];
        let arr0:NSMutableArray = ["你好","好不好"];

        // mark -  属性传值
        foVC.arr0 = arr0;

        //方法调用
        foVC.swMethod0();
        foVC.swMethod1(str: "da");
        let str = foVC.swMethod2(str: "ddd");
        print(str);

        // mark -  代码块回调
        foVC.bkBlock0 {
            print("你可以的");
        };
        foVC.bkBlock1 { (res) in
            print(res);
        }
        foVC.bkBlock_2_{ (res, str) in
            print(res, "+", str);
        }
        foVC.bkBlock3(p1: "1", p2: "2", p3: "3") { (res0, res1, res2, res3) in
            print(res0,res1,res2,res3);
        }
        self.present(foVC, animated: true) {

        };
    }
