ios - 从Swift访问Objective-C block

Question

我在FileManagerHelper中有以下Objective-C代码:

+(void)getMyVideoObject:(NSString *)videoId completion:(void (^)(MyVideoObject *myVideoObject, NSError *error)) completionBlock
{

}

对于从Objective-C进行的调用:

 [FileManagerHelper getMyVideoObject:videoId completion:^(MyVideoObject *myVideoObject, NSError *error) {

}];

但是，如何从Swift调用此getMyVideoObject？
FileManagerHelper.getMyVideoObject( .....？

Answer 1

1)添加到桥接头文件中(将.swift文件添加到Objective-C项目时生成的-Bridging-Header.h文件)

#import "FileManagerHelper.h"

2)在快速代码中使用以下调用

FileManagerHelper.getMyVideoObject("id") { (video, error) in

}
