  • glTexImage2D behavior on iPhone and other OpenGL ES platforms

    - by spurserh
    Hello, I am doing some work which involves drawing video frames in real time in OpenGL ES. Right now I am using glTexImage2D to transfer the data, in the absence of Pixel Buffer Objects and the like. I suspect that the use of glTexImage2D with one or two frames of look-ahead, that is, using several textures so that the glTexImage2D call can be initiated a frame or two ahead, will allow for sufficient parallelism to play in real time if the system is capable of it at all. Is my assumption true that the driver will handle the actual data transfer to the hardware asynchronously after glTexImage2D returns, assuming I don't try to use the texture or call glFinish/glFlush? Is there a better way to do this with OpenGL ES? Thank you very much, Sean

  • iPhone - Dismiss modal view by a UITabBarController

    - by ncohen
    Hi everyone, I've got into a very strange problem. I created my own UITabBarController to customize it and it works pretty well... except for the modal views. When I dismiss the modal view (present/dismiss from the UITabBarController) with an animation, it waits until the animation did finished and goes to the first controller of the tab bar! Why does the controller change? and how can I fix it? Thanks PS: My UITabBarController view is on the main window and has a UITabBar on it. The controllers (which are managed by the tab bar) are on the main window over the tab bar controller view with a shorter height. When I present the modal view, I bring the tab bar controller view to front.

  • iPhone SDK - UITabBarConroller and custom design

    - by Cheryl
    Hi I am having a problem with my tab bars at the bottom of the screen. The designer has decided it should be one colour (not black) when inactive and another colour when active. I have worked out how to replace the main colour of the tabbar by subclassing UITabBarController and doing this:- - (void)viewDidLoad { [super viewDidLoad]; CGRect frame = CGRectMake(0.0, 0, self.view.bounds.size.width, self.view.bounds.size.height); UIView *v = [[UIView alloc] initWithFrame:frame]; //get percentage values from digitalcolour meter and enter as decimals v.backgroundColor = [UIColor colorWithRed:.0 green:.706 blue:.863 alpha:1]; [tabBar1 insertSubview:v atIndex:0]; [v release]; } I just can't see how to make the active tabbar be a separate colour when it is selected. I have tried subclassing UITabBarItem but there doesn't seem to be any property for me to set to change the background colour of the tab. They also want to have the icons on the tab bar not be blue and grey and I can't figure out how to do that. In the ViewController for one tab bar item I have put this into viewdidload:- myTabBarItem *tabItem = [[myTabBarItem alloc] initWithTitle:@"listOOO" image:[UIImage imageNamed:@"starcopy.png"] tag:1]; tabItem.customHighlightedImage=[UIImage imageNamed:@"starcopy.png"]; self.tabBarItem=tabItem; [tabItem release]; tabItem=nil; and in my subclass of UITabBarItem I have put this:- -(UIImage *) selectedImage{ return self.customHighlightedImage; } Only I don't see the icon at all. If I put this into the viewDidLoad of my subclass of UITabBarController:- for (UITabBarItem *item in tabBar1.items){ item.image = [UIImage imageNamed:@"starcopy.png"]; } Then all my tab bars have the icon but they are blue (and grey when inactive) how would I get them not to become blue but stay their original colour? If you have any light on this problem please help as I have been banking my head on the wall for 2 days now and it's getting me down. Thanks in advance Cheryl

  • iphone tab bar controller and core data.

    - by Sway
    Ok bit of a newbie type question. I want to use Core Data, together with Tab and Navigation controllers. In XCode if I create a Navigation Based Application I get the option to choose Core Data. Whereas If I create a Tab Bar Application I don't get the choice. I understand that Tab Bars display view controllers so it kinda makes sense. However given that by default it sticks the basic Core Data code in the Application delegate I don't see why this isn't offered. At the moment I'm creating the two projects and cutting and pasting between them. Does this omission in XCode seem weird to you? Is it some sort of oversight? Thanks, Matt

  • Problem with Google App Engine Appstats

    - by Taylor L
    I'm having an issue getting Appstats to work correctly. Using /appstats or /appstats/stats ends up in an infinite loop that keeps redirecting back to /appstats/stats. This results in a 404 error saying the page isn't redirecting properly. Any idea what the issue is? Here are the relevant lines in my appengine-web.xml. I've tried using both /appstats/stats and /appstats and they both have the same issue. <admin-console> <page name="Appstats" url="/appstats/stats" /> </admin-console> Below are the http headers showing the infinite redirect loop: http://mysite.appspot.com/appstats/stats GET /appstats/stats HTTP/1.1 Host: mysite.appspot.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv: 1.9.2.3) Gecko/20100401 Firefox/3.6.3 (.NET CLR 3.5.30729) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/ *;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Cookie: USER_LOCALE=en_US; JSESSIONID=POTIUPPpEmjHZoaNDWOSTA; ACSID=AJKiYcHiwT8jH7e01V9O5iFu3kpBhDd3k3oBwwxylv5u0DbJ- utvdpsgdb4Xim2WXwobkJmgTGGljvuh94_yVQ__- VPnBsTtUAhRjSyZ2Lv3G7oUHAxTsCWHJIMChGT3- XUyUNx8wxwvJisL_RTXH8Hc4TTLh_rVHm2k8gk8kgdbVZXexSV0K- a3coELTecWIBolt0qLd5L-5vALm382KsqbHorPXqoZMPTvR_06g_mR1cbmF2Ihnk6YhP7no58BNpESM9HvFyKNKXODo39hF4oaZCcW0Q9TBqUMgsrBqlcIh3- VvC7qvH0n_nAtrLTBbK_swnOFvCDcaf3whT9ty0CJ0VRNuNqIPOLHIeQAMgwXUNMr89P64EsgmuyONHR67glCQXEPOGXIaT1vcBJFwFoeNUqjdp824fHvoVhaL7Xlav- LTIFuM3f_ymHLmibk57PRuXUYEaAG HTTP/1.1 302 Found Location: http://mysite.appspot.com/appstats/stats X-AppEngine-Estimated-CPM-US-Dollars: $0.645553 X-AppEngine-Resource-Usage: ms=18965 cpu_ms=27884 api_cpu_ms=0 Set-Cookie: ACSID=AJKiYcF_YA7PB18b3T5OO7vEMo31f1hFhO8xKqFRiBUGrCr4YABAAyugZXcDfKMOM- r0FiK8xlOPfQWx3tOWIJ6ueOqK89X8M9YfHIs8WKUcSs6PwNZSKV0HKxvbqeWxfZI_cpo2YoS73s_RPlyEvjaYLOf6iXPpWeYyKTAbSqPOEBnVnTk3oso6ur66CIj3FnN8vsHfbanqY4sbaRsNj9pLjWZco0quYLOK1fd4wRZx_oAvk3jOlfAj7BZ7p9L1bO8oVCMpVn19cwT6zvO2-9RSjfiOPAacw7Cg0MT30r7Fr7SCj7VcSPAye4lc7tb9KL9ztZEk0xbEX-9vC6vHM_VfPJ54Kb_FycxE6lACsKTE4hj0bOa2-2quaOP0NSxfoH9ozLlQQCsGhpWBnlu__W06D0GqDqxcDUu2HocYqWuLi91aoa- aRTkqB_qo4aAa3OvHeKoFgwrS; expires=Mon, 12-Apr-2010 19:41:49 GMT; path=/ Date: Sun, 11 Apr 2010 19:42:08 GMT Pragma: no-cache Expires: Fri, 01 Jan 1990 00:00:00 GMT Cache-Control: no-cache, must-revalidate Content-Type: text/html Server: Google Frontend Content-Length: 0 ---------------------------------------------------------- http://mysite.appspot.com/appstats/stats GET /appstats/stats HTTP/1.1 Host: mysite.appspot.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv: 1.9.2.3) Gecko/20100401 Firefox/3.6.3 (.NET CLR 3.5.30729) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/ *;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Cookie: USER_LOCALE=en_US; JSESSIONID=POTIUPPpEmjHZoaNDWOSTA; ACSID=AJKiYcF_YA7PB18b3T5OO7vEMo31f1hFhO8xKqFRiBUGrCr4YABAAyugZXcDfKMOM- r0FiK8xlOPfQWx3tOWIJ6ueOqK89X8M9YfHIs8WKUcSs6PwNZSKV0HKxvbqeWxfZI_cpo2YoS73s_RPlyEvjaYLOf6iXPpWeYyKTAbSqPOEBnVnTk3oso6ur66CIj3FnN8vsHfbanqY4sbaRsNj9pLjWZco0quYLOK1fd4wRZx_oAvk3jOlfAj7BZ7p9L1bO8oVCMpVn19cwT6zvO2-9RSjfiOPAacw7Cg0MT30r7Fr7SCj7VcSPAye4lc7tb9KL9ztZEk0xbEX-9vC6vHM_VfPJ54Kb_FycxE6lACsKTE4hj0bOa2-2quaOP0NSxfoH9ozLlQQCsGhpWBnlu__W06D0GqDqxcDUu2HocYqWuLi91aoa- aRTkqB_qo4aAa3OvHeKoFgwrS HTTP/1.1 302 Found Location: http://mysite.appspot.com/appstats/stats X-AppEngine-Estimated-CPM-US-Dollars: $0.002243 X-AppEngine-Resource-Usage: ms=64 cpu_ms=93 api_cpu_ms=0 Date: Sun, 11 Apr 2010 19:42:08 GMT Content-Type: text/html Server: Google Frontend Content-Length: 0

  • Simultaneous gesture recognizers in Iphone SDK

    - by minaevs
    I need to catch two different swipping gestures using UISwipeGestureRecognizer(for example, UISwipeGestureRecognizerDirectionRight and UISwipeGestureRecognizerDirectionLeft). When I add two different recognisers with addGestureRecognizer method, only last added recognizer works. I've read that I need to implement gestureRecognizer:shouldRecognizeSimultaneouslyWithGestureRecognizer: method of UIGestureRecognizerDelegate protocol, but nothing works. Can anyone help with simple example of catching two or more same gestures? Thanks!

  • Retain count problem iphone sdk

    - by neha
    Hi all, I'm facing a memory leak problem which is like this: I'm allocating an object of class A in class B. // RETAIN COUNT OF CLASS A OBJECT BECOMES 1 I'm placing the object in an nsmutablearray. // RETAIN COUNT OF CLASS A OBJECT BECOMES 2 In an another class C, I'm grabbing this nsmutablearray, fetching all the elements in that array in a local nsmutablearray, releasing this first array of class B. // RETAIN COUNT OF CLASS A OBJECTS IN LOCAL ARRAY BECOMES 1 Now in this class C, I'm creating an object of class A and fetching the elements in local nsmutable array. //RETAIN COUNT OF NEW CLASS A OBJECT IN LOCAL ARRAY BECOMES 2 [ALLOCATION + FETCHED OBJECT WITH RETAIN COUNT 1] My question is, I want to retain this array which I'm displaying in tableview, and want to release it after new elements are filled in the array. I'm doing this in class B. So before adding new elements, I'm removing all the elements and releasing this array in class B. And in class C I'm releasing object of class A in dealloc. But in Instruments-Leaks it's showing me leak for this class A object in class C. Can anybody please tell me wheather where I'm going wrong. Thanx in advance.

  • Iphone UIScrollView and multiple visible images

    - by joynes
    Hi! Im trying to implement a UIScrollView including multiple images, using paginate. The problem is that I want more then one page to be visible in the UIScrollView, but only one page should be selected. I found several solutions in which you handle touch down/up (touchesBegan and touchesEnded) myself and scrollRectToVisible, but I want to avoid this if possible. A sample solution for that can be found at: http://forums.macrumors.com/showthread.php?t=634462 I dont get why its so easy if you only need to display one page at a time in the UIScrollView , but seems really hard if you want to show more pages. Could you solve it with zooming? /Br Johannes

  • Change dynamic web reference from web./app.config

    - by Snæbjørn
    I have a problem changing a dynamic web reference in the config file. Changing the url in the config file doesn't have any effect. I have to change the url in .settings and compile for it to change. I added the web reference using the wizard. Set the URL behavior to dynamic, which added the relevant XML tags in config file. In my solution I have the web API (web reference) in a separate project (class lib), so I referenced the project and copied the <applicationSettings> over. <applicationSettings> <StartupProject.Properties.Settings> <setting name="WebReference" serializeAs="String"> <value>http://someurl/somefile.asmx</value> </setting> </StartupProject.Properties.Settings> </applicationSettings> Note that it's <StartupProject.Properties.Settings> and not <WebRefProject.Properties.Settings>. Are there some limitations I'm not aware of or am I doing something wrong?

I understand how to add view controllers to the navigator using the TTURLMap, but do I need to add a navigator for each tabbar item? I'm lost.

  • iPhone provisioning profile suddenly stops working (not expired)

    - by Tristan
    Hey there! We have a couple of iPhones in our office. All of them have provisioning profiles installed on them. One of the phones (my bosses :S) all of a sudden won't allow me to install apps to it, complaining that a valid provisioning profile cannot be found. The profile isn't expired, and the problem is, I'm guessing, not with the XCode files, as I can install the same project to all the other phones. Does anyone know why this might have occurred or how I can fix this? Thanks! Tristan
