Question

我有UIImagePickerController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

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

 }

我发现了这个：How to select any Video or Movie file from UIImagePickerController

但无法转换为Swift：

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

 }

提前谢谢

Answer 2

Swift 4.使用此：

guard info[UIImagePickerControllerMediaType] != nil else { return }
let mediaType = info[UIImagePickerControllerMediaType] as! CFString

switch mediaType {
case kUTTypeImage:

    break
case kUTTypeMovie:

    break
case kUTTypeLivePhoto:

    break
default:
    break
}

Answer 3

if mediaType.isEqualToString(kUTTypeImage as String){

}

Answer 4

> Swift 4 像这样覆盖didFinishPickingMediaWithInfo：

public func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    guard let mediaType = info[UIImagePickerController.InfoKey.mediaType] as? String else {return}

    switch mediaType {
    case kUTTypeMovie:
        //handle movie here
    case kUTTypeImage:
        //handle image here
    }}
