  • iPhone OpenGL and NSTimer issues

    - by Kyle
    I have an NSTimer that runs at 60hz. With an OpenGL scene loaded and rendering, my game can get 60fps, solid, all day long.. Then if I go and recompile the app, or reload it, it will get 40fps. Same resources loaded. I've been running into this problem for years, and I just want to know why. It's crazy, and I want to know if I should just abandon this stupid Timer. Conditions are not different on my 3GS between loads. It will just get 40fps sometimes. Obviously the clockrate is not different between loads, so the performance figures should be constant given a constant scene. Here is a log of my framerates: A good load: :-) FrameRate: 61 FrameRate: 61 FrameRate: 61 FrameRate: 60 FrameRate: 60 FrameRate: 61 FrameRate: 60 FrameRate: 60 FrameRate: 61 FrameRate: 60 FrameRate: 61 Now, I'll go ahead and do nothing, recompile, and run: FrameRate: 43 FrameRate: 50 FrameRate: 45 FrameRate: 48 FrameRate: 40 FrameRate: 45 FrameRate: 42 FrameRate: 41 FrameRate: 42 FrameRate: 44 FrameRate: 41 FrameRate: 46 ^- Massive difference visually. What the flying heck could cause this? SAME area of the scene, SAME camera setup. No variables are different.

  • drawing images and lines over UIScrollView

    - by Jorge
    I'm programming an app in which one of the ViewControllers is showing an UIScrollView that shows an image. I'd like to load an image (pushpin in png format) and draw it (and delete it) in some points of the UIScrollView image. I'd also would like to draw bezier paths in that image (and deleting them). I've programmed several apps but this is the first time I face graphic programming and don't know where to start from. Any suggestions? Thanks!

  • iPhone tilt direction

    - by Tate Allen
    Hi all, I am making a simple, tilt controlled game using UIKit. So far, when I tilt the device the character moves in the appropriate direction. What I want him to do is to change the direction he is facing when I tilt the device. For example, when I tilt it left, I want the character to face left. Is there a way to detect whether the device was tilted left or right? If so, could you point me in the right direction please. Thanks, Tate

  • Creating an iphone book application

    - by ennuikiller
    I have some experience creating iphone applications and would now like to create an iphone book application. Browsing the Book category in iTunes it seems to there is a standard format for building these apps, however, googling for how to build an iphone book app produces no useful results. This type of application is also not addressed in any of the iphone development books I've seen. Is there a standard method fot building these book applications? Or is it simply copying the text is some format (pdf, txt, html?) and then writing a document handling api? It seems there already must exist apis for doing this. Can anyone point me in the right direction. Thanks in advance!

  • Tableview lags, and glitches while scrolling due to images loading in each cell

    - by Luis Tovar
    Hey Guys! Me again! Can someone provide me with some example code of how to properly load images in a tablecell without making the tableview glitch while scrolling. For example if you look at fandago's app, when scrolling through their movies you can see that the image is loaded asynchronously so that the scroll isnt jumping, lagging, or glitchy. Thanks in advance. Right now I have the images loading just fine but it is glitchy as i scroll because the images are loading on main thread. I am creating an app very similar to fandango. PS I am downloading these images via xml. (you know what i mean) Thanks!!

  • How to declare NSString constants for passing to NSNotificationCenter

    - by synic
    I've got the following in my .h file: #ifndef _BALANCE_NOTIFICATION #define _BALANCE NOTIFICATION const NSString *BalanceUpdateNotification #endif and the following in my .m file: const NSString *BalanceUpdateNotification = @"BalanceUpdateNotification"; I'm using this with the following codes: [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(updateBalance:) name:BalanceUpdateNotification object:nil]; and [[NSNotificatoinCenter defaultCenter] postNotificationName:BalanceUpdateNotificatoin object:self userInfo:nil]; Which works, but it gives me a warning: Passing argument 1 of 'postNotificationName:object:userInfo' discards qualifiers from pointer target type So, I can cast it to (NSString *), but I'm wondering what the proper way to do this is.

  • Memory leak for NSDictionary loaded by plist file

    - by Pask
    I have a memory leak problem that just can not understand! Watch this initialization method: - (id)initWithNomeCompositore:(NSString *)nomeCompositore nomeOpera:(NSString *)nomeOpera { if (self = [super init]) { NSString *pathOpere = [[NSBundle mainBundle] pathForResource:kNomeFilePlistOpere ofType:kTipoFilePlist]; NSDictionary *dicOpera = [NSDictionary dictionaryWithDictionary: [[[NSDictionary dictionaryWithContentsOfFile:pathOpere] objectForKey:nomeCompositore] objectForKey:nomeOpera]]; self.nomeCompleto = [[NSString alloc] initWithString:nomeOpera]; self.compositore = [[NSString alloc] initWithString:nomeCompositore]; self.tipologia = [[NSString alloc] initWithString:[dicOpera objectForKey:kKeyTipologia]]; } return self;} Then this little variation (note self.tipologia): - (id)initWithNomeCompositore:(NSString *)nomeCompositore nomeOpera:(NSString *)nomeOpera { if (self = [super init]) { NSString *pathOpere = [[NSBundle mainBundle] pathForResource:kNomeFilePlistOpere ofType:kTipoFilePlist]; NSDictionary *dicOpera = [NSDictionary dictionaryWithDictionary: [[[NSDictionary dictionaryWithContentsOfFile:pathOpere] objectForKey:nomeCompositore] objectForKey:nomeOpera]]; self.nomeCompleto = [[NSString alloc] initWithString:nomeOpera]; self.compositore = [[NSString alloc] initWithString:nomeCompositore]; self.tipologia = [[NSString alloc] initWithString:@"Test"]; } return self;} In the first variant is generated a memory leak, the second is not! And I just can not understand why! The memory leak is evidenced by Instruments, highlighted the line: [NSDictionary dictionaryWithContentsOfFile:pathOpere] This is the dealloc method: - (void)dealloc { [tipologia release]; [compositore release]; [nomeCompleto release]; [super dealloc];}

  • Convert bitmap image information into CGImage in iPhone OS 3

    - by giftederic
    I want to create a CGImage with the color information I already have Here is the code for converting the CGImage to CML, CML_color is a matrix structure - (void)CGImageReftoCML:(CGImageRef *)image destination:(CML_color &)dest{ CML_RGBA p; NSUInteger width=CGImageGetWidth(image); NSUInteger height=CGImageGetHeight(image); CGColorSpaceRef colorSpace=CGColorSpaceCreateDeviceRGB(); unsigned char *rawData=new unsigned char[height*width*4]; NSUInteger bytesPerPixel=4; NSUInteger bytesPerRow=bytesPerPixel*width; NSUInteger bitsPerComponent=8; CGContextRef context=CGBitmapContextCreate(rawData, width, height, bitsPerComponent, bytesPerRow, colorSpace, kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big); CGColorSpaceRelease(colorSpace); CGContextDrawImage(context, CGRectMake(0, 0, width, height), image); CGContextRelease(context); int index=0; for (int i=0; i<height; i++) { for (int j=0; j<width; j++) { p.red=rawData[index++]; p.green=rawData[index++]; p.blue=rawData[index++]; p.alpha=rawData[index++]; dest(i,j)=p; } } delete[] rawData; } Now I want the reverse function, which converts CML into CGImage. I know all the color and alpha information to create the image, which stored in the matrix CML, but how can I do that?

  • iTunes Music Store Link Maker — how to search from within my app?

    - by prendio2
    I'm writing a music reference app and for each album (pulled from last.fm) would like to link to the ITMS (if the album is in the store). iTunes link maker web tool http://apple.com/itunes/linkmaker/ is great for getting links for a known album but I need to access it programatically from within my app. This NSLog blogpost which is from 2003 but was referenced more recently in another question here seems to offer the only solution I've come across so far, suggesting to submit a query to: phobos.apple.com/WebObjects/MZSearch.woa/wa/advancedSearchResults? Put "itms://" before it and the link will work in iTunes, put "http://" before it and the link will work in Camino (Safari sometimes spits back a malformed XML error). The tags that are of importance are as follows: songTerm - song title artistTerm - artist name albumTerm - album name composerTerm - composer name term - all fields The suggestion is that would using http:// rather than itms:// the server will return an XML document of results instead of opening iTunes but either way I am sent directly to iTunes. Is it possible to get back a list of results?

  • Disabling home button on iPhone/iPad

    - by alku83
    First of all, I'm completely aware that doing this will get my app rejected by Apple, that it's a poor user experience, and so on. My question is fairly simple, is there a way using private APIs to disable the home button? The aim is to effectively put an iPad into kiosk mode.

  • iPhone 4.0 on iPhone but still Ad-Hoc compile for 3.1.3?

    - by Mark
    Device: Version : 3.1 Build: 3511 Device: iPhone OS: iPhone OS 4.0 xCode 3.2.2 (Old) xCode 3.2.3 (New; For iPhone 4.0 Beta) Background: As you can see I installed 4.0 on my iPhone as I read on this forum it's really hard to near impossible to downgrade back to 3.1.3, but it's my only device I have and use for development. When I try to continue to develop and build with the old xCode it tells me that "No provisioned iPhone OS device is connected". When I select Simulator it does compile and build, however when I spread this file it does not work on the devices of my testers, they get a Signed error. When I run the new xCode, it does compile and build on the Device and when I spread this file, it does work on the devices of my testers (which are running the current official version 3.1.3). Questions: Why is there a difference between building for Simulator and Device? A simulator build never seem to work on the devices of my testers because of signing issues and the build for device does work. Currently it seems the old xCode became useless, however I read that you may not use the Beta xCode to build your application for release. So knowing the above how am I able to pull this off with my current setup due the fact the old xCode won't let me build properly.

  • Regular Expression doesn't match

    - by dododedodonl
    Hi All, I've got a string with very unclean HTML. Before I parse it, I want to convert this: <TABLE><TR><TD width="33%" nowrap=1><font size="1" face="Arial"> NE </font> </TD> <TD width="33%" nowrap=1><font size="1" face="Arial"> DEK </font> </TD> <TD width="33%" nowrap=1><font size="1" face="Arial"> 143 </font> </TD> </TR></TABLE> in NE DEK 143 so it is a bit easier to parse. I've got this regular expression (RegexKitLite): NSString *str = [dataString stringByReplacingOccurrencesOfRegex:@"<TABLE><TR><TD width=\"33%\" nowrap=1><font size=\"1\" face=\"Arial\">(.+?)<\\/font> <\\/TD>(.+?)<TD width=\"33%\" nowrap=1><font size=\"1\" face=\"Arial\">(.+?)<\\/font> <\\/TD>(.+?)<TD width=\"33%\" nowrap=1><font size=\"1\" face=\"Arial\">(.+?)<\\/font> <\\/TD>(.+?)<\\/TR><\\/TABLE>" withString:@"$1 $3 $5"]; I'm no an expert in Regex. Can someone help me out here? Regards, dodo

  • UINavigationController flashes white when I add it to a superview

    - by Chris Stamper
    Hey guys, I'm adding a NavigationController as a subview of my main view, with the flip animation (like a utility app/flipview thing). Here's how I'm doing it: [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:.7]; [UIView setAnimationTransition:([self.tableController.view superview] ? UIViewAnimationTransitionFlipFromLeft : UIViewAnimationTransitionFlipFromRight) forView:self.tableHostView cache:YES]; [self.tableController.view removeFromSuperview]; settingsView* backView1 = [[settingsView alloc] initWithNibName:@"settingsView" bundle:nil]; backView1.delegate = self; UINavigationController* settingsNavStack = [[UINavigationController alloc]initWithRootViewController:backView1]; [backView1 release]; settingsNavStack.view.frame = CGRectMake(0, 0, 320, 460); settingsNavStack.navigationItem.title = @"Settings"; [self setBackView:settingsNavStack]; [settingsNavStack release]; [self.tableHostView addSubview:self.backView.view]; [[self backView]setDelegate: self]; When it loads, the view comes in very nicely. However, the navigation bar stays white until like .2 secs after the animation finishes. Anyone know why the navigation bar wouldn't display right away?

  • Is there a way to pause a CABasicAnimation?

    - by mclaughlinj
    I have a basic spinning animation of the iPhone. Is there any way that I can "pause" the animation so that the position of the view will be maintained? I guess one way of doing this would be to cause the animation to "complete" instead of calling "remove" on it, how would I do that? CABasicAnimation* rotationAnimation; rotationAnimation = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"]; rotationAnimation.toValue = [NSNumber numberWithFloat: M_PI * 2]; rotationAnimation.duration = 100; rotationAnimation.cumulative = YES; rotationAnimation.repeatCount = HUGE_VALF; rotationAnimation.removedOnCompletion = NO; rotationAnimation.fillMode = kCAFillModeForwards; [myView.layer addAnimation:rotationAnimation forKey:@"rotationAnimation"];

  • CoreLocation on iPod Touch, location caching and other conundrums...

    - by Moshe
    I have a few questions about Core Location. 1) Should the user refuse permission for my app to use core location, or core location is unavailable for some reason, is there a fallback? (Device Locale, for example?) 2)Can I cache a device's location for next time? Does Core Location do this itself? 3)I really need the sunset time in the user's area during the mid-spring season and I have a function to do that, once I have the Latitude and Longitude of the device. Perhaps I can just make an assumption about the time based on Locale? (Example: In the US, assume approximately 7:00pm.)
