ios - 确定图像选择器媒体类型是视频还是照片 [英] ios - Determine if image picker media type is video or photo

问题描述

我有 UIImagePickerController，它正在从图库中选择照片或视频，选择项目后，我想确定选择哪一个，照片或视频

I have UIImagePickerController which is choosing photo or video from gallery, after selecting item, I want to determine which one is chosen, photo or video

 func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
    let mediaType = info[UIImagePickerControllerMediaType]

 }

我发现了这个:如何选择来自 UIImagePickerController 的任何视频或电影文件

但无法转换为 Swift:

but could not translate to Swift:

 if (CFStringCompare ((__bridge CFStringRef) mediaType, kUTTypeMovie, 0) == kCFCompareEqualTo) {

 }

先谢谢你

推荐答案

使用这个

if let mediaType = info[UIImagePickerControllerMediaType] as? String {

    if mediaType  == "public.image" {
        print("Image Selected")
    }

    if mediaType == "public.movie" {
        print("Video Selected")
    }
}
