I am creating a settings modal in my app, and I would like to be able to "navigate" to categories of settings within the modal. There are examples of this in apps, like Flipboard for example. If you open the settings, a modal opens, and you can tap a category. It navigates you to a new page (still within the modal), and you get a back button that will bring you back to the modal page. When you close the modal, your navigation stack is still valid, they seem to be two separate stacks. You can even navigate deeper, like open settings > Edit Profile > Change Email. You then can go back twice to

I hope we can figure out how to get around this interesting challenge with a game we are designing in an isometric style. Any help would be so awesome! QUESTION Is there a way to change the bounding box frame from a square to another shape? Maybe using a mask? PROBLEM Our problem is that we need our node's tappable area NOT to be square. Since we are tiling the nodes, their bounding boxes overlap each other, and we cannot accurately tap on the tile that we want. Hopefully our graphic below will show you what we are designing, our problem, and what our tappable area needs to be. Is there a way

This is what I need: Program for quicker making fun posters for facebook page. Posters have text, picture and frame (white line and black background). In this case, I want to insert logo on poster (png image). Depending on picture size, dimensions of frame (who in this case consits of two shapes) must automaticly be resized for picture. How to save poster from that image from link (2 shape components, 2 image components, 2 labels) as picture? How to accomplish this? What to use, where to begin? I hope that this question will not be removed. If you put all the frames, shapes and pictures inside

I'm doing an app to record a video. What I would like is that when the app is recording the video, each frame is also saved in an arraylist of RGB values in order to extract particular information from it. I know that the two processes (video recording and extraction of frames) are asynchronous, but this is not a problem: the process of extraction can finish after the video recording. Can someone tell me how I can extract the frames from the video? Thanks very much. Using the camera object you can override a function setPreviewCallback . from that function you would get an array of byte data.

I create a UITextView, add text to it, and put it in the view (with a container) UITextView *lyricView = [[UITextView alloc] initWithFrame:screen]; lyricView.text = [NSString stringWithFormat:@"\n\n%@\n\n\n\n\n\n", lyrics]; [container addSubview:lyricView]; [self.view addSubview:container]; I then get the size of it for use with a button and add it to the UITextView CGRect size = [lyrics boundingRectWithSize:CGSizeMake(lyricView.frame.size.width, MAXFLOAT) options:NSStringDrawingUsesLineFragmentOrigin attributes:@{NSFontAttributeName:[lyricView font]} context:nil]; UIButton *doneButton =

does anyone know the difference between defining a vertical scrollbar on a frame like this: <ScrollViewer Grid.Row="2" VerticalScrollBarVisibility="Auto"> <Frame Name="Frame1" ScrollViewer.CanContentScroll="True" /> </ScrollViewer> or like this: <ScrollViewer Grid.Row="2"> <Frame Name="Frame1" ScrollViewer.VerticalScrollBarVisibility="Auto" ScrollViewer.CanContentScroll="True" /> </ScrollViewer> This frame is nested in a WebBrowser control and setting it the first way correctly displays the vertical scrollbar and is only visible when it needs to scroll (auto). When I set it the second way the
