使用未声明的标识符'kUTTypeMovie' [英] Use of undeclared identifier 'kUTTypeMovie'

问题描述

我收到错误消息 - 在以下代码中使用未声明的标识符'kUTTypeMovie'

I am getting the error message - Use of undeclared identifier 'kUTTypeMovie'

-

-(IBAction)selectVideo:(id)sender {
    UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
    imagePicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
    imagePicker.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie, nil];

    imagePicker.delegate = self;
    [self presentModalViewController:imagePicker animated:YES];
}

它出了什么问题？

推荐答案

您必须将框架MobileCoreServices添加到项目中，然后导入它：

You have to add the framework MobileCoreServices to the project, and then import it:

#import <MobileCoreServices/MobileCoreServices.h>

这将使问题消失。
