Question

我可以通过桥接头来访问swift项目中的目标c类。但是我如何实现该对象的c类回调方法。

示例：我在ClassObjectiveC中有一个回调decleare

typedef void(^PlayCompleteCallBack)(BOOL playSuccess, NSString *processfileName);
@property (nonatomic, copy)   PlayCompleteCallBack playCompleteCallBack;

在目标c

我可以像这样访问

ClassObjectiveC *obj = [[ClassObjectiveC alloc]init];

[obj setPlayCompleteCallBack:^(BOOL playSuccess, NSString *processfileName){

 }];

但是在Swift中，当我想访问这个回调时，我该如何实现呢。感谢

Answer 1

以这种方式playCompleteCallBack。

let yourObject = ClassObjectiveC()
yourObject.playCompleteCallBack = { (success, name) in
    //Access success and name here
}

Answer 2

试试这个语法

 obj.playCompleteCallBack = {(_ playSuccess: Bool, _ processfileName: String) -> Void in
         //Your code
     }

如何在swift文件中访问目标c块
