ios - 如何检查相机是否打开以捕获图像或在 iOS 中录制视频？

Question

在我的应用程序中，应用程序允许用户捕获图像/录制视频。但是我不知道如何用下面的方法检查结果。

- (void) imagePickerController: (UIImagePickerController *) picker
 didFinishPickingMediaWithInfo: (NSDictionary *) info {
}

您的解决方案总是受到赞赏。提前致谢。

Answer 1

这里是你需要的:

 - (void) imagePickerController: (UIImagePickerController *) picker
 didFinishPickingMediaWithInfo: (NSDictionary *) info {
    NSString *mediaType = info[UIImagePickerControllerMediaType];

    if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) {
        // Media is an image

        UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];

    }
    else if ([mediaType isEqualToString:(NSString *)kUTTypeVideo] || [mediaType isEqualToString:(NSString *)kUTTypeMovie])
    {
        // Media is a video
        // Video URL
        NSURL *localUrl = (NSURL *)[info valueForKey:UIImagePickerControllerMediaURL];
    }
}
