[iPhone SDK] Resizing an OpenGL surface

So I took the MyEAGLView from the Crash Landing demo. It sets up a basic OpenGL view for me to draw 2d elements on. And it's been working fine. But I want to resize the view when the user rotates the device. So I set autoresizesView = YES on the view. Which causes it to destroy and recreate the OpenGL frame buffer / render buffer. But afterward, all I get is a purple screen rendered. And I don't really know where to start looking for how to resolve this issue.

Hey there,
You need a development certificate in order to compile the code using OpenGL (we stopped our project too). So a friend of mine applied for the 99 USD dev kit to get a certificate so we could do this type of development.
The free SDK does not let you upload to the iPhone yet so thats the only solution for now it looks like. Hopefully we'll get our certificate soon but who knows when that will happen.

  • IPhone SDK - OpenGL ES

    Hello,
    I've done quite a bit of OpenGL programming and was excited to use OpenGL ES via the iPhone SDK. It turns out that OpenGL ES content cannot be simulated and must be run on the iPhone itself.
    I live in Canada, where the iPhone hasn't officially been released (I own an iPod Touch). Is there any way to start using OpenGL ES now that will allow me to get a feel for how the code will run on the iPhone?
    Thanks.

    Thanks for the reply. i did try that suggestion, but the cube still isn't rendering to anything even remotely resembling a cube. I was pretty sure I did a sizeof(GLUNSIGNEDSHORT) and got 4 on NSLog, but I could be wrong. I exported this data out of Cheetah 3D. Perhaps there is a better program for exporting 3d data for iphone? I'm at a loss for what else could be wrong. Probably I am missing one gl comand or parameter, I just can't figure out what it is.

  • Learning iPhone SDK - Trying to draw an image

    Although I have programmed for Mac in the last years, I have never used Mac-specific technologies as Cocoa (I have programmed more in OpenGL, SDL, and the like).
    Now I am getting started with the iPhone SDK. I'd like to do some OpenGL|ES stuff, but since it is not supported in the Simulator, and you need to join the Developer Program to test stuff on directly on the device (and admission of new members is closed right now), I am focused on other stuff right now, like using Core Graphics for drawing images on the iPhone.
    My application is based on the Cocoa Touch Application template. I left the default code except for a few changes.
    In file "UntitledAppDelegate.m", I have changed the method applicationDidFinishLaunching to:
    - (void)applicationDidFinishLaunching:(UIApplication *)application {
    window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
    contentView = [[[MyView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]] autorelease];
    [window addSubview:contentView];
    [window makeKeyAndVisible];
    Then, in the MyView interface file (MyView.h), I have added the attribute "UIImageView* image;" to the class, which is declared as a property, and synthesized.
    In the class implementation (MyView.m), I have changed the method initWithFrame to:
    - (id)initWithFrame:(CGRect)frame {
    if (self = [super initWithFrame:frame]) {
    self.backgroundColor = [UIColor darkGrayColor];
    image = [self loadImageView:@"box01.png"];
    [self addSubview:image];
    return self;
    loadImageView is a private method I have implemented as:
    - (UIImageView *)loadImageView:(NSString *) imageName {
    UIImage *img = [UIImage imageNamed:imageName];
    UIImageView *theView = [[UIImageView alloc] initWithImage:img];
    return theView;
    Since I have loaded the UIImage, and initialized a UIImageView with it, and the image view is added as a subview of the main view attached to the window, I thought it should be everything needed to draw an image on the screen. But nothing is visible. The screen is simply black when I run this on the Simulator. It doesn't even set the background to dark gray.
    So I need some help with this, I sure that anyone with experience in Mac programming will know how to help me.
    Thank you in advance.

    I removed the XIB file from the project, but that didn't help. It was a problem with my inexperience with Objective-C. When accessing class properties in a method of the same class, i was not putting "self." before the property (in C++ that's redundant). For example, in the line "window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];". After adding it, it works correctly.

  • Troubleshooting iPhone SDK build 9M2199 beta 7 ...

    I successfully installed the iPhone SDK last night but seem to have a few problems: a) the DOC SET for the "Apple iPhone OS 2.0" does not seem to work, retried several times.
    b) when trying to follow the "Getting started" tutorial I noticed that the install did not install a "Cocoa Touch template" in the New Project.
    I did try to re-install the same thing again but still no luck.

    I am glad I am not the only one here! I kept on thinking the installation must have gone wrong somewhere.
    The probable new names I think are:
    Cocoa Touch OpenGL Application -> OpenGL ES Application
    Cocoa Touch Tab Bar -> Tab Bar Application
    Cocoa Touch Utility -> Utility Application
    The unclear ones:
    Cocoa Touch Application -> ?
    Cocoa Touch List -> ?
    ? -> Navigation-Based Application
    ? -> View-Based Application
    ? -> Window-Based Application
    Does anyone know when the tutorials are updated to what the SDK actually looks like?

  • Problem in iPhone SDK Sample: [CrashLanding ]

    iPhone SDK build : build 9M2199a
    Sample: CrashLanding
    Version: 1.7
    OpenGL swap buffer method seems to fails sometimes resulting in a crappy blink display. The display seems split into two images. The screen goes messy, I can view the backbuffer blinking over frontbuffer with no drawing update on it.
    Thanks,
    Julien Meyer
    Jadegame.com

    I developed my application based on the CrashLanding sample. I have inherited the same rendering failure. The swap occurs, but it's presenting stale data for one of the frames. The stale data appears to be the first frame rendered. The failure occurs either immediately, or not at all. Restarting the application usually makes the problem go away.
    Has anyone determined a fix for this?
    Thank you,

  • Round triangle in iPhone SDK

    Hi,
    I'm a newbie to iPhone app development. How do you draw a rounded triangle using iPhone SDK? CGRect draws the normal rectangle.
    Thanks.

    to your comment.. you have to code that triangle either way if we're talking about diff screen devices down the road.. still just as simple to resize an image resource unless it's already a built-in iPhone/touch resource.. which if that were the case I'm with you all the way!

  • IPhone SDK - What is the equivalent of a combo box

    I have a screen where there are quite a few items which are of the multiple-choice type. In other platforms i use a combo box (pick lists) to do this.
    On the iPhone SDK the only thing that comes close is the UIPicketView which is ugly IMHO. it takes too much real estate and too heavy.
    Is this is the only control available now?
    Also does the UIPicker come with an associated control which will launch the picker? What i mean is on other platforms and on the web there is a text field with a button with a down arrow next to it. Clicking either on the text field or the down arrow drops the list down. Is there a similar control on the iPhone which when clicked launches the picker OR do i have to create a button or a custom view which will launch the picker?
    Thanks for reading this and for your feedback.
    -TRS

    I do not believe there is an equivalent of -D in the DB JVM, a possible solution is:
    Load a properties file into the DB using Loadjava, then open this file from your Java code using Properties.load(), then iterate the properties calling System.setProperty().

  • IPhone SDK CodeSign Error: Redux (latest OS X update is broken)

    This bug - http://discussions.apple.com/thread.jspa?threadID=1455699&start=0&tstart=0 - is back. My AdHoc project, which worked perfectly last week, has just stopped building, with this:
    "object file format invalid or unsuitable"
    As soon as I upgraded from 10.5.7 to 10.5.8, this bug appeared.
    However, this bug was officially fixed in 10.5.7 - so, I'm guessing here, Apple has accidentally re-created it.
    Unfortunately, I cannot add to the original post, because Apple has frozen the topic.
    So, here's a new topic to ask if anyone else is having this problem, and what they did about it - is it exactly the same as the old bug? or is it different in some way?
    I'm going to try some of the workarounds for the old bug - but hacking command line scripts isn't fun, and I'm worried I might break something even worse .

  • IPhone SDK 2.2 memory corruption

    Hello. I'm working on an application for iPhone SDK 2.2 and seem to be having weird memory corruption problems. Not necessarily leaks because using Instruments shows my memory stamp never going above about 1.8 megs. The nature of the app is a database of animals so I'm constantly loading and unloading sounds and images. None of the objects are very large (at most I'll have 4 800k pngs loaded at once) and I've checked and rechecked my alloc/retain/release and everything is in order (hence no memory usage increase). However...after using the application for a while I'll notice strange behavior. For example:
    1) we have a UILabel as the title for each page. After a while the font size of this will change.
    2) I have several screens with a subclassed UIScrollView where images are loaded and then added to. The problem shows itself here by the images not showing up. there's no crash, stepping through the debugger shows that the image loads up fine, it's just that the image is not there.
    3) I have a UILabel at the top of an animal description screen, which in the nib file is called "Animal Name" by default. This will change to show "Animal Name" at the top.
    I've removed all audio in our latest build so that isn't the problem. What I'm starting to suspect is that altering anything defined in a nib file will cause corruption. For example, the UIScrollView is defined in the nib file, and I constantly am reassigning the contents of that with a UIImageView. This UIImageView is handled within the subview class like :
    UIImageView *imgView = [[UIImageView alloc] initWithImage: [ UIImage imageWithContentsOfFile:[[NSBundle mainBundle ] pathForResource:imageToLoad ofType:@"png" ]] ];
    imgView.tag = 50;
    [self addSubview:imgView ];
    [ imgView release ];
    Then later when moving away from the screen I'll find that view's tag and remove it from the superview (since addSubView increases the retain count, the alloc+addSubView is cancelled by release+removeFromSuperView)
    I can't explain why titles that are never changed would be affected, but it must somehow be related. What I'm wondering is: are there any known issues involving modification of the contents of objects defined in Nib files? Perhaps the memory allocated when initWithNibName is restrained, then any modification of objects allocated within it can cause corruption. I'm starting to think I should just alloc and free anything modified in code and skip using nib files altogether (I reset the text on buttons for example). If this is a known issue please let me know. I'll give you more information if I can.
    Thank you

    Just download the huge SDK package and install. No need to uninstall the old SDK.

  • Problem in set selectedTextcolor in uitableview cell in iPhone SDK 3.1.2

    Hello,
    I set selected text color in uitableview cell using cell.selectedTextColor = [UIColor whiteColor]; for iPhone SDK 2.2.1.
    Now i use iPhone SDK 3.1.2, So for that i make change as per documentation for that i use textLabel properties. But selectedTextColor is not exit.
    So Now for SDK 3.1.2 how to set selectedTextColor?..
    Thank you.

    The textLabel property is an instance of UILabel, so it has its own textColor, textAlignment, and font properties. E.g.:
    cell.textLabel.text = @"foo";
    cell.textLabel.textColor = [UIColor whiteColor];
    cell.textLabel.textAlignment = UITextAlignmentLeft;
    Hope that helps!

  • IPhone SDK : Communication between iPhone client and a remote server

    Hi,
    This is w.r.t iPhone Cocoa Touch native application.
    i need to populate my application 's data from a remote application server ( which in turn connects to the database) . I require some tips in the communication between client sitting on the iPhone and the remote application server. I am planning to proceed in XML transaction way.
    I referred the SeismicXML sample application provided by Apple. In this sample,client reads the physically existing xml file from @"http://earthquake.usgs.gov/eqcenter/catalogs/eqs7day-M2.5.xml"; and the client parses the xml file and display the content on the table view.
    i have following 2 queries ,
    1. I do not want to read from a physically present file,i want the data to be transferred on the go.
    Means, request should be sent from the client to a application server and the server process returns the data in form of xml file ( but its not creating any physical xml file) .
    Basically i am looking for request - response concept.
    2. Can we call a java process(which returns xml data) running on a remote server from the cocoa touch client.? If not java process,what would be other best way...
    i am going through the Apple provided frameworks. Do any of the iPhone SDK frameworks support this request? If some one has any idea on the above mentioned queries, pls help me.
    any pointers will also be helpful.
    It might be too early to talk about these,but i have to take some business decision related on this.
    thanks in advance.

    You already know how to send a string via HTTP Post? And you know how to make XML into a string? Put the two together.

    Further research has led me believe now that iPhone SDK will only run on Intel based machines. If that is indeed the case, neither machine will work for me.

  • IPhone SDK custom installation, what do I need?

    FYI, I will be developing iPhone Apps only and don't want to install unnecessary things.
    Options are:
    Developer Tools Essentials (Required.)
    iPhone SDK (Obviously need.)
    System Tools (Do I need? It's checked by default.)
    UNIX Development Support (Do I need? It's checked by default.)
    Mac OS X 10.3.9 Support (Know I don't need, not developing anything for OS X, particularly not an old version.)
    WebObjects (Do I need? It's NOT checked by default.)
    Thanks.

    Hi--
    Welcome to the Apple Discussions.
    System Tools (Do I need? It's checked by default.)
    I would suggest "yes." That's the installer for the performance tools. Shark, especially, can be invaluable for profiling your code.
    UNIX Development Support (Do I need? It's checked by default.)
    I'd suggest "yes." It's command line tools you might want at some point (to help in automating builds, etc.). Some aspects of scripting with OS X can also be made easier if you have the UNIX dev support installed.
    WebObjects (Do I need? It's NOT checked by default.)
    Definitely not, that's a web application framework you'd use if you were building a web site.
