# OCBridgeSwiftToCall[OC与swift的数据传输]

##简介

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的相互调用](https://gitee.com/chenzm_186/OCBrigdeSwiftDemo)

----

### 1、swift之间的页面跳转与返回

1、present方式跳转

```swift
 @objc func btnAction(_ sender:UIButton){
        let subVC  = SubVC();
        self.present(subVC, animated: true) {
            NSLog("👺👺👺:%@", subVC);
        };
        NSLog("👺👺👺:%@____%@",sender,self);
    }
```
2、返回

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

### 2、oc监听swift推送的通知：

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

 - oc接收通知
```oc
-(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：

```swift
 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);
    }
```
![通知打印结果][1]

### 4、oc调用swift的代理方法：

- 编辑协议方
```swift
///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
```oc
///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);
}

```
![代理协议打印结果][2]

###5、swift调用oc代码块

- oc文件类
```oc
///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
```swift

let vc  = ThiVC();
///代码块调用
vc.thiBlock = {(str) -> () in
    print("代码块方法");
}

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

});
```
![提示][3]

###6、oc对swift的属性传值、方法调用、代码块调用

- swift方法类
```swift
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：
```oc
    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:^{
        
    }];

```
![此处输入图片的描述][4]

###7、swift对oc的属性传值、方法调用、代码块调用

- xxx.h文件
```oc
@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
```oc
- (void)viewDidLoad {
    [super viewDidLoad];
    NSLog(@"%@",self.titStr);
    !self.clickBlock?:self.clickBlock();
}

-(void)testAction{
    NSLog(@"调用方法");
}

```

- xxx.swift文件

```oc

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: {
                
});
```
![打印结果][5]

###8、swift之间的传值
```swift
    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) {
            
        };
    }
```
