objective-c - 如何调用完成 block ？

Question

如何在 ObjectiveC 中调用这个基于 Swift 的完成 block ？

public var completionBlock: IMGLYEditorCompletionBlock?
public typealias IMGLYEditorCompletionBlock = (IMGLYEditorResult, UIImage?) -> Void

这是我在 Swift 中的调用方式，但从未在 Objective C 中工作过。

func callEditorViewController() {
   var editorViewController = IMGLYMainEditorViewController()
   editorViewController.highResolutionImage = image
   editorViewController.initialFilterType = .None
   editorViewController.initialFilterIntensity = 0.5
   editorViewController.completionBlock = editorCompletionBlock
}

func editorCompletionBlock(result: IMGLYEditorResult, image: UIImage?) {
   ...
}

这是我的 Objective-C 代码，有语法错误。

-(void) editorCompletionBlock:(IMGLYEditorResult*)result img:(UIImage*)image{

}

 IMGLYMainEditorViewController *editor = [[IMGLYMainEditorViewController alloc]init];
editor.highResolutionImage = image;

 editor.completionBlock = [self editorCompletionBlock:r img:image];

调用 block 非常简单:

editor.completionBlock(result, image);

仍然觉得您更愿意设置它:

editor.completionBlock = ^(IMGLYEditorResult result, UIImage *image) {
        // do something meaningful here 
};
