你好,我需要建立从iPhone相机录制视频的应用程序.
我在网上搜索,但没有发现它在iOS 9中有效.我从这个git项目得到了这个代码:https:
//github.com/versluis/Video-Recorder
此代码打开相机,但不允许我拍摄视频.
- (IBAction)recordButton:(id)sender {
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
UIImagePickerController *picker = [[UIImagePickerController alloc]init];
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.delegate = self;
picker.allowsEditing = NO;
NSArray *mediaTypes = [[NSArray alloc]initWithObjects:(NSString *)kUTTypeMovie, nil];
picker.mediaTypes = mediaTypes;
[self presentViewController:picker animated:YES completion:nil];
} else {
UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:nil message:@"I'm afraid there's no camera on this device!" delegate:nil cancelButtonTitle:@"Dang!" otherButtonTitles:nil, nil];
[alertView show];
}
}
- (IBAction)playbackButton:(id)sender {
// pick a video from the documents directory
NSURL *video = [self grabFileURL:@"video.mov"];
// create a movie player view controller
MPMoviePlayerViewController * controller = [[MPMoviePlayerViewController alloc]initWithContentURL:video];
[controller.moviePlayer prepareToPlay];
[controller.moviePlayer play];
// and present it
[self presentMoviePlayerViewControllerAnimated:controller];
}
#pragma mark - Delegate Methods
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
// user hit cancel
[self dismissViewControllerAnimated:YES completion:nil];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
// grab our movie URL
NSURL *chosenMovie = [info objectForKey:UIImagePickerControllerMediaURL];
// save it to the documents directory
NSURL *fileURL = [self grabFileURL:@"video.mov"];
NSData *movieData = [NSData dataWithContentsOfURL:chosenMovie];
[movieData writeToURL:fileURL atomically:YES];
// save it to the Camera Roll
UISaveVideoAtPathToSavedPhotosAlbum([chosenMovie path], nil, nil, nil);
// and dismiss the picker
[self dismissViewControllerAnimated:YES completion:nil];
}
- (NSURL*)grabFileURL:(NSString *)fileName {
// find Documents directory
NSURL *documentsURL = [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject];
// append a file name to it
documentsURL = [documentsURL URLByAppendingPathComponent:fileName];
return documentsURL;
}
