1. 视频拍摄 （UIImagePickerController）

- (IBAction)captureVideo:(id)sender {
    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
        
        UIImagePickerController *picker = [[UIImagePickerController alloc] init];
        picker.delegate = self;
        picker.allowsEditing = YES;
        picker.sourceType = UIImagePickerControllerSourceTypeCamera;
        picker.mediaTypes = [[NSArray alloc] initWithObjects: (NSString *) kUTTypeMovie, nil];
        
        [self presentViewController:picker animated:YES completion:NULL];
    }
}

2. 视频播放 ，自带start、pause、progress bar （MPMoviePlayerController）

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    
    self.videoURL = info[UIImagePickerControllerMediaURL];
    [picker dismissViewControllerAnimated:YES completion:NULL];
    
    self.videoController = [[MPMoviePlayerController alloc] init];
    
    [self.videoController setContentURL:self.videoURL];
    [self.videoController.view setFrame:CGRectMake (0, 0, self.view.frame.size.width, 460)];
    [self.view addSubview:self.videoController.view];
    
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(videoPlayBackDidFinish:)
                                                 name:MPMoviePlayerPlaybackDidFinishNotification
                                               object:self.videoController];
    [self.videoController play];
    
}
