Answer 1

首先，创建一个UIImagePickerController

在你的类，你将需要实现UIImagePickerControllerDelegate协议，并将其连接起来，以对选择器的delegate财产。一旦用户选择了某些内容，您应该能够从didFinishPickingMediaWithInfo中获取所选媒体的位置。

// untested 
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 
{ 
    // this is the file system url of the media 
    NSURL* videoUrl = [info objectForKey:UIImagePickerControllerMediaURL]; 

    // TODO: read in data at videoUrl and write upload it to your server 
} 

Answer 2

起点为UIImagePickerController选择视频，MPMoviePlayerController和MPMoviePlayerViewController用于播放。

Answer 3

如果使用UIImagePickerController，一定要玩的sourceType属性，而不是访问直播相机的库。详情请参阅UIImagePickerControllerSourceType。

这是你的选择：

enum { 
    UIImagePickerControllerSourceTypePhotoLibrary, 
    UIImagePickerControllerSourceTypeCamera, 
    UIImagePickerControllerSourceTypeSavedPhotosAlbum 
}; 

Answer 4

UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init]; 
imagePickerController.delegate = self; 
NSArray *mediaTypesAllowed = [NSArray arrayWithObjects:@"public.image", @"public.movie", nil]; 
[imagePickerController setMediaTypes:mediaTypesAllowed]; 
[self presentModalViewController:imagePickerController animated:YES];
