目前要知道什么是媒体类型我获得“public.image”如果用户选择图像到相机胶卷或拍摄新照片,“public.movie”如果是电影。
我阅读了UIImagePickerControllerMediaType的Apple文档,我看到了:
let UIImagePickerControllerMediaType: String
常量
UIImagePickerControllerMediaType
Specifies the media type selected by the user.
The value for this key is an NSString object containing a type code such as kUTTypeImage or kUTTypeMovie.
这是我的代码:
let mediaType:String = info[UIImagePickerControllerMediaType] as! String
if mediaType == "public.image" {
....
} else if mediaType == "public.movie" {
....
}
如何将mediaType与官方文档值(kUTTypeImage或kUTTypeMovie)进行比较?
答案 0 :(得分:2)
mediaType == String(kUTTypeImage)
