Disable the retake, play and use video screen UIImagePickerController

问题

I am just wanting one screeen:

When using the UIImagePickerController it uses two screens.

But I don't want this one:

Is this possible?

@Fahri is right AVFoundation is more flexible but if you want to stick with UIImagePickerController what you could do is turn off the camera control by setting showsCameraControls property to NO, then present your own view and custom methods.

Change your code to:

takeVideo

- (IBAction)takeVideo:(UIButton *)sender {

    UIToolbar *toolBar=[[UIToolbar alloc] initWithFrame:CGRectMake(0, self.view.frame.size.height-54, self.view.frame.size.width, 55)];

    toolBar.barStyle =  UIBarStyleBlackOpaque;
    NSArray *items=[NSArray arrayWithObjects:
                    [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel  target:self action:@selector(cancelVideo)],
                    [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace  target:nil action:nil],
                    [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCamera  target:self action:@selector(shootVideo)],
                    [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace  target:nil action:nil],
                    [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace  target:nil action:nil],
                    nil];
    [toolBar setItems:items];

    // create the overlay view
    UIView *overlayView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height-44)];
    overlayView.opaque=NO;
    overlayView.backgroundColor=[UIColor clearColor];

    // parent view for our overlay
    UIView *cameraView=[[UIView alloc] initWithFrame:self.view.bounds];
    [cameraView addSubview:overlayView];
    [cameraView addSubview:toolBar];

    picker = [[UIImagePickerController alloc] init];

    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] == NO){
        NSLog(@"Camera not available");
        return;
    }

    picker.sourceType = UIImagePickerControllerSourceTypeCamera;
    picker.mediaTypes = [[NSArray alloc] initWithObjects: (NSString *) kUTTypeMovie, nil];
    picker.delegate = self;

    // hide the camera controls
    picker.showsCameraControls=NO;
    [picker setCameraOverlayView:cameraView];

    [self presentViewController:picker animated:YES completion:nil];

}

shootVideo

-(void) shootVideo {
    [picker startVideoCapture];
}

cancelVideo

- (IBAction)cancelVideo {
    [self dismissViewControllerAnimated:YES completion:nil];
}

If you have already checked the documentation of UIImagePickerController before posting your question, then you can use AVFoundation library to build your own camera controller, with any controls and screens you want. Good Luck!
