  • iPhone: In landscape-only, after first addSubview, UITableViewController doesn't rotate properly

    - by Clay Bridges
    A minimal illustrative Xcode project for this is available on github. On my UIWindow, when I add second (and subsequent) UITableView's as subviews, they do not rotate properly, and thus appear sideways. This is only tested in the Simulator. Here's a little code for you: - (void)applicationDidFinishLaunching:(UIApplication *)application { ShellTVC* viewA = [[ShellTVC alloc] initWithTitle:@"View A"]; ShellTVC* viewB = [[ShellTVC alloc] initWithTitle:@"View B"]; // The first subview added will rotate to landscape correctly. // Any subsequent subview added will not. // You may try this by various commentings and rearranging of these two statements. [window addSubview:[viewA tableView]]; [window addSubview:[viewB tableView]]; [window makeKeyAndVisible]; } viewB appears sideways. Comment out the addSubview for viewB, and viewA appears correctly. Do that for viewA only, and viewB appears correctly. I am not creating these UITableViewControllers via NIBs, though the UIWindow is. In case you are wondering, ShellTVC is-a UITableViewController, and implements this method: - (BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft); } Also, I have set the UIInterfaceOrientation in the plist file to UIInterfaceOrientationLandscapeLeft. Probably related -- and unanswered -- SO questions here and here.

  • iPhone: Memory leak when using NSOperationQueue...

    - by MacTouch
    Hi, I'm sitting here for at least half an hour to find a memory leak in my code. I just replaced an synchronous call to a (touch) method with an asynchronous one using NSOperationQueue. The Leak Inspector reports a memory leak after I did the change to the code. What's wrong with the version using NSOperationQueue? Version without a MemoryLeak -(NSData *)dataForKey:(NSString*)ressourceId_ { NSString *path = [self cachePathForKey:ressourceId_]; // returns an autoreleased NSString* NSString *cacheKey = [self cacheKeyForRessource:ressourceId_]; // returns an autoreleased NSString* NSData *data = [[self memoryCache] valueForKey:cacheKey]; if (!data) { data = [self loadData:path]; // returns an autoreleased NSData* if (data) { [[self memoryCache] setObject:data forKey:cacheKey]; } } [[self touch:path]; return data; } Version with a MemoryLeak (I do not see any) -(NSData *)dataForKey:(NSString*)ressourceId_ { NSString *path = [self cachePathForKey:ressourceId_]; // returns an autoreleased NSString* NSString *cacheKey = [self cacheKeyForRessource:ressourceId_]; // returns an autoreleased NSString* NSData *data = [[self memoryCache] valueForKey:cacheKey]; if (!data) { data = [self loadData:path]; // returns an autoreleased NSData* if (data) { [[self memoryCache] setObject:data forKey:cacheKey]; } } NSInvocationOperation *touchOp = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(touch:) object:path]; [[self operationQueue] addOperation:touchOp]; [touchOp release]; return data; } And of course, the touch method does nothing special too. Just change the date of the file. -(void)touch:(id)path_ { NSString *path = (NSString *)path_ NSFileManager *fm = [NSFileManager defaultManager]; if ([fm fileExistsAtPath:path]) { NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:[NSDate date], NSFileModificationDate, nil]; [fm setAttributes: attributes ofItemAtPath:path error:nil]; } }

  • iphone: UIwebview curl effect

    - by eshalev
    Hello, I would like to make a standard view container which will give me the curl animation effect on multiple views. Something like uiscrollview and paging, only with a different animation(curl). I will be using UIwebviews as my separate pages. The problem: I do not know how to trap swipes in UIwebviews, But I see that UIscrollview implments this (swiping a uiwebview in a uiscrollview will bring me to the next view). I am therefore assuming that the implmentation of UIscrollview is trapping UIwebview swipes. How can i achieve the same functionality? I also need the UIWebview to keep functioning (as when embedding it in a uiscrollview)

  • Replacing image in sprite - cocos2d game development of iphone

    - by sagar
    I want to change the sprite image. Say for example. mainSprite=[Sprite spriteWithFile:@"redFile.png"]; [self addChild:mainSprite]; Here, Sprite is already added to a layer. I have mainSprite (pointer) which can access it. If I change [mainSprite setOpacity:150]; it works perfectly. But Here I want to change the sprite image instead of opacity. But Don't know how? Thanks in advance for helping me. Sagar

  • Memory management in ObjC/iPhone

    - by Manu
    Hi, I have question in memory management (objective C). There are two ideal scenario. ============================= scenario 1 ======================================== (void) funcA { MyObj *c = [otherObj getMyObject]; [c release]; } -(MyObj *) getMyObject //(this method is available in other OtherObj.m file) { MyObj *temp = [[MyObj alloc] init]; // do smothing here return temp; } ============================= scenario 2 ======================================== (void) funcA { MyObj *c = [otherObj getMyObject]; } -(MyObj *) getMyObject //(this method is available in other OtherObj.m file) { MyObj *temp = [[myObj alloc] init]; // do smothing here return [temp autorelease]; } myObj is holding huge chunk of data. In first scenario I am getting myObj(allocated) from other file so I have to release in my own method. (as per any C/C++ language library ,like strdup will return string duplicate which will realase later by developer not by strdup method). In second scenario I am getting myObj(allocated) from otherObj.m file so otherObj.m file is responsible to release that allocated memory(mean autorelease)? Is it right? Please let me know Which scenario is more efficient and valid as per apple memory guidelines. Please Please don't show me any document link. Thanks Manu

  • iPhone XCODE Programming make a UIWebView Scrollable

    - by Antonio Murgia
    here is the problem! I have a UIWebView in my programs that loads a php page. The problem is that if the page has a lot of lines i cannot see them. I can "scroll" the UIWebView but when I leave the finger from the screen the page comes back to the original state. I don't want to scale pages to fit the view cause if I do that the letters become too small. I would like to find a way to scroll pages how it is possible in Safari. Hope i have explained the problem. Thank you in advance Antonio

  • iPhone: CATiledLayer/UIScrollView wont scroll after zooming and only zooms to anchor point

    - by Brodie4598
    Here is the problem... I am using CA Tiled Layer to display a large jpg. The view loads okay, and when I go to scroll around, it works fine. However, as soon as I zoom in or out once, it scrolls to the top left (to the anchor point) and will not scroll at all. The zooming works fine, but I just cannot scroll. Here is my code: #import <QuartzCore/QuartzCore.h> #import "PracticeViewController.h" @implementation practiceViewController //@synthesize image; - (void)viewDidLoad { NSString *path = [[NSBundle mainBundle] pathForResource:@"H-5" ofType:@"jpg"]; NSData *data = [NSData dataWithContentsOfFile:path]; image = [UIImage imageWithData:data]; CGRect pageRect = CGRectMake(0, 0, image.size.width, image.size.height); CATiledLayer *tiledLayer = [CATiledLayer layer]; tiledLayer.anchorPoint = CGPointMake(0.0f, 1.0f); tiledLayer.delegate = self; tiledLayer.tileSize = CGSizeMake(1000, 1000); tiledLayer.levelsOfDetail = 6; tiledLayer.levelsOfDetailBias = 0; tiledLayer.bounds = pageRect; tiledLayer.transform = CATransform3DMakeScale(1.0f, -1.0f, 0.3f); myContentView = [[UIView alloc] initWithFrame:self.view.bounds]; [myContentView.layer addSublayer:tiledLayer]; UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:self.view.bounds]; scrollView.delegate = self; scrollView.contentSize = pageRect.size; scrollView.minimumZoomScale = .2; scrollView.maximumZoomScale = 1; [scrollView addSubview:myContentView]; [self.view addSubview:scrollView]; } - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView { return myContentView; } - (void)drawLayer:(CALayer *)layer inContext:(CGContextRef)ctx { NSString *path = [[NSBundle mainBundle] pathForResource:@"H-5" ofType:@"jpg"]; NSData *data = [NSData dataWithContentsOfFile:path]; image = [UIImage imageWithData:data]; CGRect imageRect = CGRectMake (0.0, 0.0, image.size.width, image.size.height); CGContextDrawImage (ctx, imageRect, [image CGImage]); } @end

  • iPhone Icon file in bundle blank when building for App store distribution

    - by Boiler Bill
    I have been spinning my wheels for a couple hours on why when I build my app with my distribution cert with the device as the target the Icon.png file in the bundle is empty. If I build with my developer cert or against the simulator the Icon.png in the bundle matches the one in my project file. I have verified my Icon.png is 57X57, has no alpha channel, had extra finder attributes removed. I even took one of the Icon.png files from my first application that is in the store today, and it didn't work either. Here is the output from the build results: CopyPNGFile build/Distribution-iphoneos/myApp.app/Icon.png Icon.png cd /Users/wrbarbour/projects/myAppTWO/myApp setenv COPY_COMMAND /Developer/Library/PrivateFrameworks/DevToolsCore.framework/Resources/pbxcp setenv PATH "/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin:/Developer/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin" "/Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Plug-ins/iPhoneOS Build System Support.xcplugin/Contents/Resources/copypng" -compress "" /Users/wrbarbour/projects/myAppTWO/myApp/Icon.png /Users/wrbarbour/projects/myAppTWO/myApp/build/Distribution-iphoneos/myApp.app/Icon.png Can someone get me pointed in the right direction?

  • How to tile a UIWebView? (iPhone)

    - by franky
    I need to use tiles with a UIWebview to improve the rendering and scrolling of the content. I tried to find some info in Google but it seems that there are no examples or technical info about this subject. I am doing some test with CATiledLayer class without luck... Basically, I want to replicate the same that Mobile Safari does with the content of a website. You can see how Safari makes tiles when you see the squared background. Any help will be very welcome! Thanks in advance, Franky

  • iPhone: NSTimer Countdown (Display Minutes:Seconds)

    - by user298261
    Hello! I have my timer code set up, and it's all kosher, but I want my label to display "Minutes : seconds" instead of just seconds. -(void)countDown{ time -= 1; theTimer.text = [NSString stringWithFormat:@"%i", time]; if(time == 0) { [countDownTimer invalidate]; } } I've already set "time" to 600, or 10 minutes. However, I want the display to show 10:59, 10:58, etc. until it reaches zero. How do I do this? Thanks!

  • FBConnect for iPhone: sessionDidNotLogin, sessionDidLogout, session didLogin not called the second t

    - by Irene
    My problem is very similar to this question, however I am posting a new one, as the answer to the aforementioned does not seem to solve my problem. I have a multiview application - the first view is where the user logs in to Facebook, and the second where he picks an image and uploads it there. The first time the app runs, everything works fine, however if I return to the login view and press logout, then any calls to sessionDidNotLogin, sessionDidLogout or session didLogin don't seem to work. I found out that the first time, if I NSLog(@"%@",session.delegates); I have 2; my LoginViewController and the FBLoginButton. However, apart from that first time, the same log prints only the LoginViewController and not the FBLoginButton. I guess this is connected somehow, but I don't know how to solve it. Do I have to manually add the FBLoginButton to the session delegates, or I'm doing something else wrong here? Thank you for any help/suggestion.

  • Iphone: UIWebview and double taps

    - by Eyal
    I would like to trap a double tap event in a UIWebView. I have derived a class from UIWebController. When I double tap it seams that the UIWebController itself is responding to my double taps instead of my class. The weird thing is that when I change the inheritance to inherit from UIView everything works just fine. Below are snippets from my code which is supposed to invoke a pop-up when double tapped. In the init function: //Setup action for double tap UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleDoubleTap:)]; tap.numberOfTapsRequired = 2; [super addGestureRecognizer:tap]; [tap release]; And Also: - (void)handleDoubleTap:(UIGestureRecognizer *)gestureRecognizer { UIAlertView *someError = [[UIAlertView alloc] initWithTitle: @"Network error" message: @"Hello" delegate: self cancelButtonTitle: @"Ok" otherButtonTitles: nil]; [someError show]; [someError release]; //[[NSNotificationCenter defaultCenter] postNotificationName:NOTIFICATION_FLIP_TO_PAGE_VIEW object:nil]; }

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

  • switch views using a button, going to a table view, iphone

    - by Jaime Rae
    My program has 4 buttons and each button calls a different table view. That works fine, but my problem is, the view controller I'm using brings up a table view that covers up my navigation bar and my tab bar. I need to replace that coding with something that will bring up a table and not cover up my nav and tab bars. Here is the coding I'm using: -(IBAction)buttonNorthWest { NorthWestViewController *nwController = [[NorthWestViewController alloc] initWithNibName:@"NorthWestView" bundle:nil]; self.nwViewController = nwController; [self.view insertSubview:nwViewController.view atIndex:0]; [self presentModalViewController:nwViewController animated:YES]; [nwController release]; } The [self presentModalViewController....] is the problem. Does anyone know how I can replace that code with something that keeps my nav and tab bars? Thanks, Jaime
