  • problems programmatically creating UIView on iPad App

    - by user3871
    I have been struggling with this problem for a few days. My iPad app is designed to be a portrait game. To satisfy Apple's expection, I also support landscape mode. When it goes into landscape mode, the game goes into a letterbox format with back borders on the sides. My problem is I am creating the UIWindow and UIView programmatically. For some unkown reason, the touch controls are "locked" in to think I'm always in landscape mode. And even though visually in portrait mode everything looks correct, the top and bottom of the screen does not respond to touch. To summarize how I am setting this up, let me provide the skeletal framework of what I'm doing: in main.cpp: int retVal = UIApplicationMain(argc, argv, nil, @"derbyPoker_ipadAppDelegate"); In the delegate, I am doing this: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { CGRect screenBounds = [[UIScreen mainScreen] bounds]; CGFloat scale = [[ UIScreen mainScreen] scale ]; m_device_width = screenBounds.size.width; m_device_height = screenBounds.size.height; m_device_scale = scale; // Everything is built assuming 640x960 window = [[ UIWindow alloc ] initWithFrame:[[UIScreen mainScreen] bounds]]; viewController = [ glView new ]; [self doStateChange:[blitz class]]; return YES; } The last bit of code sets up the UIView... - (void) doStateChange: (Class) state{ viewController.view = [[state alloc] initWithFrame:CGRectMake(0, 0, m_device_width, m_device_height) andManager:self]; viewController.view.contentMode = UIViewContentModeScaleAspectFit; viewController.view.autoresizesSubviews = YES; [window addSubview:viewController.view]; [window makeKeyAndVisible]; } The problem seems to related to the line viewController.view.contentMode = UIViewContentModeScaleAspectFit; If I remove that line, touch works correctly in portrait mode. But the negative is when I'm landscape mode, the game stretches incorrectly. So That's not a option. The frustrating thing is, when I originally had this set up with a NIB file, it worked fine. I have read through the docs about UIWindow, UIViewController and UIView and have tried about everything to no avail. Any help would be greatly appreciated.

  • Is it possible to prevent iPhone/iPad orientation changing in the browser?

    - by BoomShaka
    I've seen similar questions on this issue, but they are related to native apps. I build web apps for the iPhone/iPad that run in the browser (Safari). I was wondering if there is a way to prevent orientation change in the browser, perhaps via some meta tag. I know of the viewport meta tag which allows you to specify scale and zooming capabilities, so figured maybe there is something similar for orientation. I doubt it is possible, but I thought I'd just pop a question on here to see.

  • Printing images with same orientation in Windows 7

    - by Notinlist
    I have generated many graphs (GraphViz .dot, about 35 pcs) from a grammar and then I generated .png files from it. All of them are small graphs with a few (2 to 5) nodes on it. I would like to print them, 9 or 12 per page. The problem is that Windows 7 Print Pictures guesses orientation for every image on the grid individually. How can I force Windows 7 Print Pictures to use the same orientation for all pictures (use the files as-is, just do the fitting) What alternative solution can I use for my task which does not include repetitive manual labor? (OS: Windows 7 64 bit, regularly updated.) Thanks in advance!

  • MacBook Pro USB port provides more current in Mac OS X than in Windows

    - by AngryHacker
    I have a MacBook Pro with both Mac OS X Lion and Windows (under BootCamp) installed. While in Windows, I tried to charge my iPad 3 via the USB port. The iPad says "Not charging", but really, it does, just super slow (4-5% per hour). The reason for this is that the iPad requires 2.1 A of current, but a standard USB port provides 0.5 A. However, if I switch to Mac OS X, the iPad states that it is charging and it does at a rate of about 10% per hour. The only takeaway from this is that either OS X puts out more current on the USB port or that it recognizes the iPad and acts accordingly. Can someone provide more information on what is actually happening?

  • Fixing parent controller's elements after screen orientation

    - by Jonas Anderson
    I have a tab bar application with mixed orientation support for only some views. One of the child view controller shown from one of the tab's navigation controller is displayed only in Landscape mode. In order to accomplish this, I've done the view transformation for the child view as suggested here: Is there a documented way to set the iPhone orientation? The only problem I'm seeing is that after I've performed the orientation adjustment for the child controller and then readjusted orientation back to normal on its dismissal, the contents of the (parent) navigation controller is still shown with Landscape mode dimensions despite the navigation controller reporting the correct value for the interfaceOrientation. How do I ensure that view's size is reset to match the orientation without hardcoding screen dimensions? I have the following in the root navigation controller's viewWillAppear (invoked after the child controller is dismissed): - (void)viewWillAppear:(BOOL)animated { NSLog(@"viewFrame: (%2f, %2f), width: %2f, height: %2f\n", self.view.frame.origin.x, self.view.frame.origin.y, self.view.frame.size.width, self.view.frame.size.height); // Frame values are (0, 0) for (x,y) width: 320, height: 367 before I // displayed child controller. // Frame values are (0,0) width: 480, height: 219 after returning from child // controller -- still has the landscape dimensions NSLog(@"orientation: %d", self.interfaceOrientation); // reports portrait as expected } I've tried to invoke 'layoutIfNeeded' as well as 'setNeedsDisplay' on the view but neither of them bring the view contents into the correct display. Any suggestions would be greatly appreciated.

  • How do I reset the scale/zoom of a web app on an orientation change on the iPhone?

    - by Elisabeth
    I'm having the same problem that a couple of others have had with getting the correct behavior in a web app on an orientation change, and there doesn't seem to be an obvious solution - I've seen this question asked a couple of times on Stack Overflow and no one's yet been able to answer it. When I start the app in portrait mode, it works fine. Then I rotate into landscape and it's scaled up. To get it to scale correctly for the landscape mode I have to double tap on something twice, first to zoom all the way in (the normal double tap behavior) and again to zoom all the way out (again, the normal double tap behavior). When it zooms out, it zooms out to the correct NEW scale for landscape mode. Switching back to portrait seems to work more consistently; that is, it handles the zoom so that the scale is correct when the orientation changes back to portrait. I am trying to figure out if this is a bug? or if this is something that can be fixed with Javascript? With the viewport meta content, I am setting the initial-scale to 1.0 and I am NOT setting minimum or maximum scale (nor do I want to). I am setting the width to device-width. Any ideas? I know a lot of people would be grateful to have a solution as it seems to be a persistent problem. Thank you!

  • OT: Improbable use for an iPad?

    - by merrillaldrich
    Here's an interesting tidbit: I have noticed an even more pronounced trend toward centralized or virtual workstations lately. Both my wife and I can sit at home, as we are now, at the dining room table and work on our laptops (exciting life, I know!) but both of us are not actually working locally on these machines. We are both remoting into machines at our respective workplaces. Hers is a desktop machine physically located at her desk, while mine is a virtual workstation in my company's data center...(read more)

  • [[UIDevice currentDevice] orientation] always null

    - by Toby Wilson
    As per the title. Calling [[UIDevice currentDevice] BeginGeneratingDeviceOrientationNotifications] has no effect. DidRotateToInterfaceOrientation etc events are working fine, but I need to be able to poll the device orientation arbitrarily. How can I fix/do this? The long story: I have a tab application with a navigation controller on each tab. The root view of tab number one is a graph that goes full screen when the orientation changes to landscape; however this needs to be checked whenever the view appears as the orientation change could have occurred elsewhere, so I was hoping to poll the orientation state whenever this view appears.

  • How can I debug VGA Out on an iPad?

    - by Elliot
    The Dock Connector to VGA Adapter (required for VGA out on the iPad) uses the Dock Connector, so I can't have my laptop connected at the same time. I remember reading something about a Remote debugger, but despite lots of searching, I'm unable to find it. How can I run the debugger to test VGA output of my iPad app?

  • Is there an open source UIView subclass for creating multiple, dynamic tabs in the iPhone (iPad) SDK

    - by smountcastle
    Is there an open source UIView component that supports multiple, dynamic tabbed views for the iPhone (iPad) SDK? I see several apps in the iPad App Store which utilize tabs, one such example is the Atomic Web Browser which provides a tabbed browsing experience (like Safari on the Mac or Firefox). Instead of reinventing this functionality, I'd like to reuse an existing component.

  • iPad: How to let a user write a hand-written note using a Pogo(like) stylus?

    - by MikeN
    How could I let a user jot a quick hand-written note on an iPad using a Pogo-like stylus? (Or by using their finger, some kind of stylus makes it more legible feasible.) Initial thoughts: 1) Open GL canvas? 2) Store the output as a .png/.jpg snapshot of the openGL screen (by taking a screenhot of the iPad? 3) Would the note be limited to one screenshot, could there be a scrollable area notepad to write out a long note?

  • Work from home on an iPad?

    - by Alex Basson
    The situation: My wife has a 13" MacBook Pro that she uses for email, Facebook, web surfing, and working from home. I'm about to buy us our first iPad. My wife's brother's computer just went belly-up, and she's contemplating giving him her MacBook and just using the iPad. The question is whether or not this is possible or realistic. Obviously, the iPad is well-suited for the email/web/Facebook tasks, but the working-from-home thing is an absolute must -- if the iPad can't handle that, it's a deal-breaker. For my wife, working from home means two things: Accessing her workplace computer's Windows Vista desktop, which she currently does via Remote Desktop. Editing Office documents locally, which she currently syncs via Dropbox. Being able to edit documents locally is important, because sometimes she will download documents and edit them when she doesn't have network access (e.g. on the subway). I'm more than happy to get a keyboard dock for her, so typing won't be an issue. Are there any iPad apps she can use to access her work computer and edit her work files? Thanks for any suggestions!

  • iPad USB Charging Utility for Dell Optiplex

    - by BreakPhreak
    As you probably know already, an iPad requires a certain power on USB port to be charged from. Thus, some motherboard manufacturers (such as ASUS, Gigabyte etc) had released a special driver that recognizes that an iPad is connected to the port and adjust the USB power accordingly. On one of my computers (Gigabyte motherboard) it works fine. But other one is Dell Optiplex 780 and the regular googling by "<motherboard type> + iPad charging" doesn't seem to bring encouraging results. Just for completeness: no, the iPad is not being charged without any special driver installed (out of the box) either. Any suggestions will be welcomed.

  • iPad connection to external monitor

    - by user1234
    Apple have been relatively restrictive in the way in which they have enabled the iPad to be connected to an external display i.e. only certain things like videos and images can be displayed in this way (via a converting lead). Does anyone know of a way to get around this? I.e. display any content on the iPad on an external display - not just the apps/content that Apple has designated? For example, I want to connect my iPad to an external monitor and create documents, viewing them on the monitor not the iPad display? Thanks in advance for any help.

    I have here a case for Android tablet of 10/10.2 inches. I want to know whether I can fit iPad 3 into that case. In fact, I am concerned about the thickness of iPad because that case got grasps which keeps the tablet steady. So, whether iPad is as slim as Android tablet? In the description of the case is written-"Compatible With Android 10" and 10.2" Tablet PCs (aPad/ePad)." What are these: aPad/ePad? Cheers

  • Hidden UIView Orientation Change / Layout problems

    - by gargantaun
    The Problem: I have two View Controllers loaded into a root View Controller. Both sub view layouts respond to orientation changes. I switch between the two views using [UIView transformationFromView:...]. Both sub views work fine on their own, but if... Views are swapped Orientation Changes Views are swapped again the View that was previously hidden has serious layout problems. The more I repeat these steps the worse the problem gets. Implementation Details I have three viewsControllers. MyAppViewController A_ViewController B_ViewController A & B ViewControllers have a background image each, and a UIWebView and an AQGridView respectively. To give you an example of how i'm setting it all up, here's the loadView method for A_ViewController... - (void)loadView { [super loadView]; // background image // Should fill the screen and resize on orientation changes UIImageView *bg = [[UIImageView alloc] initWithFrame:self.view.bounds]; bg.contentMode = UIViewContentModeCenter; bg.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth; bg.image = [UIImage imageNamed:@"fuzzyhalo.png"]; [self.view addSubview:bg]; // frame for webView // Should have a margin of 34 on all sides and resize on orientation changes CGRect webFrame = self.view.bounds; webFrame.origin.x = 34; webFrame.origin.y = 34; webFrame.size.width = webFrame.size.width - 68; webFrame.size.height = webFrame.size.height - 68; projectView = [[UIWebView alloc] initWithFrame:webFrame]; projectView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth; [self.view addSubview:projectView]; } For the sake of brevity, the AQGridView in B_ViewController is set up pretty much the same way. Now both these views work fine on their own. However, I use both of them in the AppViewController like this... - (void)loadView { [super loadView]; self.view.autoresizesSubviews = YES; [self setWantsFullScreenLayout:YES]; webView = [[WebProjectViewController alloc] init]; [self.view addSubview:webView.view]; mainMenu = [[GridViewController alloc] init]; [self.view addSubview:mainMenu.view]; activeView = mainMenu; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(switchViews:) name:SWAPVIEWS object:nil]; } and I switch betweem the two views using my own switchView method like this - (void) switchViews:(NSNotification*)aNotification; { NSString *type = [aNotification object]; if ([type isEqualToString:MAINMENU]){ [UIView transitionFromView:activeView.view toView:mainMenu.view duration:0.75 options:UIViewAnimationOptionTransitionFlipFromRight completion:nil]; activeView = mainMenu; } if ([type isEqualToString:WEBVIEW]) { [UIView transitionFromView:activeView.view toView:webView.view duration:0.75 options:UIViewAnimationOptionTransitionFlipFromLeft completion:nil]; activeView = webView; } // These don't seem to do anything //[mainMenu.view setNeedsLayout]; //[webView.view setNeedsLayout]; } I'm fumbling my way through this, and I suspect a lot of what i've done is implemented incorrectly so please feel free to point out anything that should be done differently, I need the input. But my primary concern is to understand what's causing the layout problems. Here's two images which illustrate the nature of the layout issues... UPDATE: I just noticed that when the orientation is landscape, the transition flips vertically, when I would expect it to be horizontal. I don't know wether that's a clue as to what might be going wrong. Switch to the other view... change orientation.... switch back....
