想问下这句 oc 代码的用 swift3 应该怎么调用？

This topic created in 3070 days ago, the information mentioned may be changed or developed.

最近在用 oc 到 swift 的迁移，对 swift 实在生疏，oc 中的 TZImagePickController 中有这么一个属性

@property (nonatomic, copy) void (^didFinishPickingPhotosHandle)(NSArray<UIImage *> *photos,NSArray *assets,BOOL isSelectOriginalPhoto);

先前的调用方式是这样的

[imagePickerVc setDidFinishPickingPhotosHandle:^(NSArray<UIImage *> *photos, NSArray *assets, BOOL isSelectOriginalPhoto) { _fileArr = photos; NSString *webImg =[NSString stringWithFormat:@"[""]; for (int i=0; i<photos.count; i++) { // [self htmlForJPGImage:photos[i]] webImg =[webImg stringByAppendingString:[self htmlForJPGImage:photos[i]]]; webImg = [webImg stringByAppendingString:@"""]; if (i != photos.count - 1) { webImg = [webImg stringByAppendingString:@",""]; } else { webImg = [webImg stringByAppendingString:@"]"]; } } NSLog(@"%@",webImg); [self evaluateJsCode:callback val:webImg webview:self.webview]; }];

想问下改写成 swift3 应该怎么写？
