  • Custom UITableViewCell rounded corners (grouped style)

    - by Urizen
    When creating a custom UITableViewCell I notice that it looks as expected in 'plain' style but that the corners of the cells are not rounded if the table view is displayed in 'grouped' style: i.e. the corners are square. I have searched but cannot find any real explanation of why this happens and, more importantly, how to remedy this effect.

  • Saving a single NSMutableDictionary in a plist

    - by yesimarobot
    I have one dictionary I need to save into a plist. The paletteDictionary always returns nil: - (void)saveUserPalette:(id) sender { [paletteDictionary setObject:matchedPaletteColor1Array forKey:@"1"]; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *path = [documentsDirectory stringByAppendingPathComponent:@"UserPaletteData.plist"]; // write plist to disk [paletteDictionary writeToFile:path atomically:YES]; } I'm reading the data back in a different view like: NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *path = [documentsDirectory stringByAppendingPathComponent:@"UserPaletteData.plist"]; NSMutableDictionary *plistDictionary = [NSMutableDictionary dictionaryWithContentsOfFile:path]; if(plistDictionary==nil ){ NSLog(@"failed to retrieve dictionary from disk"); }

  • Is there a website to lookup barcodes?

    - by strange
    Hi I know there's a http://www.upcdatabase.com/ website that allows you to lookup barcodes. This website however does not return anything for thousands of normal household items. I have seen free apps on mobile phones that can do this and list the exact product name along with price comparison. Does anyone know of good websites (even commercial ones) that have a good/reliable database that one could use for lookups?

  • UIViewController not loading a UIView

    - by Cosizzle
    Hey, I'm playing around with a script my teacher provided for a table based application. However I can't seem to get my own view to load. Files: SubViewOneController (which is a sub view, also has a nib) TapViewController (Custom UIView I created and want to add to a cell) RootViewController (Main controller which loads in the views) SimpleNavAppDelegate How it works: Within the RootViewController, there's an NSArray that holds NSDictionary objects which is declared in the -(void)awakeFromNib {} method - (void)awakeFromNib { // we'll keep track of our views controllers in this array views = [[NSMutableArray alloc] init]; // when using alloc you are responsible for it, and you will have to release it. // ==================================================================================================== // ==================================================================================================== // LOADING IN CUSTOM VIEW HERE: // allocate a set of views and add to our view array as a dictionary item TapViewController *tapBoardView = [[TapViewController alloc] init]; //push onto array [views addObject:[NSDictionary dictionaryWithObjectsAndKeys: @"Tab Gestures", @"title", tapBoardView, @"controller", nil]]; [tapBoardView release]; //release the memory // ==================================================================================================== // ==================================================================================================== SubViewOneController *subViewOneController = [[SubViewOneController alloc] init]; // This will set the 2nd level title subViewOneController.title = @"Swipe Gestures"; //set it's title //push it onto the array [views addObject:[NSDictionary dictionaryWithObjectsAndKeys: @"Swipe Gestures", @"title", subViewOneController, @"controller", nil]]; [subViewOneController release]; //release the memory } Later on I set the table view: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // OUTPUT -- see console NSLog(@"indexPath %i", indexPath.row); // OUTPUT: tapController: <TapViewController: 0x3b2b360> NSLog(@"view object: %@", [views objectAtIndex:indexPath.row]); // OUTPUT: view object: controller = <TapViewController: 0x3b0e290>; title = "Tab Gestures"; // ----- Hardcoding the controller and nib file in does work, so it's not a linkage issue ------ // UNCOMMENT TO SEE WORKING -- comment below section. //TapViewController *tapContoller = [[TapViewController alloc] initWithNibName:@"TapBoardView" bundle:nil]; //NSLog(@"tapController: %@", tapContoller); //[self.navigationController pushViewController:tapContoller animated:YES]; // ----- Random Tests ----- //UIViewController *targetViewController = [[views objectAtIndex: 0] objectForKey:@"controller"]; // DOES NOT WORK // LOADS THE SECOND CELL (SubViewOneController) however will not load (TapViewController) UIViewController *targetViewController = [[views objectAtIndex: indexPath.row] objectForKey:@"controller"]; NSLog(@"target: %@", targetViewController); // OUTPUT: target: <TapViewController: 0x3b0e290> [self.navigationController pushViewController:targetViewController animated:YES]; } Reading the comments you should be able to see that hardcoding the view in, works - however trying to load it from the View NSArray does not work. It does however contain the object in memory, seeing that NSLog proves that. Everything is linked up and working within the TapViewController nib file. So ya, im kinda stuck on this one, any help would be great! Thanks guys

  • drawing different quartz 2d

    - by Cosizzle
    Hello, I'm trying to make a small application or demo thats a tab bar application. Each bar item loads in a new view. I've created a quartzView class that is called on by the controller: - (void)viewDidLoad { quartzView *drawingView = [[quartzView alloc] initWithFrame:CGRectMake(0,0,320,480)]; [self.view addSubview:drawingView]; [super viewDidLoad]; } From my understanding, the drawRect method must be triggered in order to render the object and to draw it. This is my quartzView class: #import "quartzView.h" @implementation quartzView #pragma mark shapes // Blue Circle - (void)drawRect:(CGRect)rect { NSLog(@"Trying to draw..."); CGContextRef ctx = UIGraphicsGetCurrentContext(); //get the current context CGContextClearRect(ctx, rect); //clear off the screen //draw a red square CGContextSetRGBFillColor(ctx, 255, 0, 0, 1); CGContextFillRect(ctx, CGRectMake(10, 10, 50, 50)); } // ==================================================================================================== #pragma mark - - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { // Initialization code } return self; } - (void)dealloc { [super dealloc]; } @end So how would I go about to say, if the view is view one, draw a square if it's view two draw a circle. And so on.

  • Size of static libraries generated by XCode

    - by shaft80
    I have a project tree in XCode that looks like this: AppProject depends on ObjcWrapper that in turn depends on PureCppLib. ObjcWrapper and PureCppLib are static library projects. Combined, all sources barely reach 15k lines of code, and, as expected, the size of resulting binary is about 750Kb in release mode and slightly over 1Mb in debug mode. So far, so good. However, ObjcWraper.a and PureCppLib.a are over 6Mb each in either mode. So the first question is why it is so. But more importantly, how can I ensure that those static libs do not include parts or all of the source code? Thanks in advance!

  • Using Unit Tests While Developing Static Libraries in Obj-C

    - by macinjosh
    I'm developing a static library in Obj-C for a CocoaTouch project. I've added unit testing to my Xcode project by using the built in OCUnit framework. I can run tests successfully upon building the project and everything looks good. However I'm a little confused about something. Part of what the static library does is to connect to a URL and download the resource there. I constructed a test case that invokes the method that creates a connection and ensures the connection is successful. However when my tests run a connection is never made to my testing web server (where the connection is set to go). It seems my code is not actually being ran when the tests happen? Also, I am doing some NSLog calls in the unit tests and the code they run, but I never see those. I'm new to unit testing so I'm obviously not fully grasping what is going on here. Can anyone help me out here? P.S. By the way these are "Logical Tests" as Apple calls them so they are not linked against the library, instead the implementation files are included in the testing target.

  • Schedule multiple events with NSTimer?

  • Objective-C RGB to HSB

    - by Johannes Jensen
    Let's say I've got the colour FF0000, which is red. Finding a darker colour is easy, I just type maybe CC instead of the FF, but let's say I've got the colour AE83FC, which is a complicated colour, how the heck would I find a lighter or darker version of it automatically? I figured the easy way to do this is to convert my RGB to HSB [Hue, Saturation, Brightness] How would I do that in Objective-C? Let's say I've got a RGB which is: 1.0, 0.0, 0.0. That's red. CGFloat r = 1.0; CGFloat g = 0.0; CGfloat b = 0.0; How would I convert that to HSB and then transform the colors and make it go back to RGB to I can use CGContextRGBSetFillColor? Are there any HSB functions? Please help. :)

  • CCSprite: setTexture doesn't work when the sprite is rendered using a CCSpriteSheet

    - by srikanth rongali
    My code is in cocos2d. I am getting this error in my code. To get the fast animation I used CCSpriteSheet CCSpriteSheet *danceSheet = [CCSpriteSheet spriteSheetWithFile:@"new1.png"]; [self addChild:danceSheet]; CCSprite *danceSprite = [CCSprite spriteWithTexture:danceSheet.texture rect:CGRectMake(0, 0, 119, 320)]; [danceSheet addChild:danceSprite]; danceSprite.position = ccp(danceSprite.contentSize.width/2,danceSprite.contentSize.height/2); CCAnimation *danceAnimation = [CCAnimation animationWithName:@"dance" delay:0.1f]; int frameCount = 0; for (int x = 0; x < 13; x++) { // create an animation frame CCSpriteFrame *frame = [CCSpriteFrame frameWithTexture:danceSheet.texture rect:CGRectMake(x*119,0,119,320) offset:ccp(0,0)]; [danceAnimation addFrame:frame]; frameCount++; NSLog(@"frameCount value: %d", frameCount); if (frameCount == 13) break; } CCAnimate *danceAction = [CCAnimate actionWithAnimation:danceAnimation restoreOriginalFrame:NO ]; [danceSprite runAction:danceAction]; But when I touched the screen it is giving the error CCSprite: setTexture doesn't work when the sprite is rendered using a CCSpriteSheet

  • Advance way of using UIView convertRect method to detect CGRectIntersectsRect multiple times

    - by Chris
    I recently asked a question regarding collision detection within subviews, with a perfect answer. I've come to the last point in implementing the collision on my application but I've come across a new issue. Using convertRect was fine getting the CGRect from the subView. I needed it to be a little more complex as it wasn't exactly rectangles that needed to be detected. on XCode I created an abstract class called TileViewController. Amongst other properties it has a IBOutlet UIView *detectionView; I now have multiple classes that inherit from TileViewController, and each class there are multiple views nested inside the detectionView which I have created using Interface Builder. The idea is an object could be a certain shape or size, I've programatically placed these 'tiled' detection points bottom center of each object. A user can select an item and interactive with it, in this circumstance move it around. Here is my touchesMoved method -(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{ UITouch *touch = [[event allTouches] anyObject]; CGPoint location = [touch locationInView:touch.view]; interactiveItem.center = location; // The ViewController the user has chosen to interact with interactiveView.view.center = location; // checks if the user has selected an item to interact with if (interactiveItem) { // First get check there is more then 1 item in the collection NSUInteger assetCount = [itemViewCollection count]; //NSMutableArray that holds the ViewControllers int detectionCount = 0; // To count how many times a CGRectIntersectsRect occured UIView *parentView = self.view; // if there is more then 1 item begin collision detection if (assetCount > 1) { for (TileViewController *viewController in itemViewCollection) { if (viewController.view.tag != interactiveView.view.tag) { if (viewController.detectionView.subviews) { for (UIView *detectView in viewController.detectionView.subviews) { CGRect viewRect; viewRect = [detectView convertRect:[detectView frame] toView:parentView]; // I could have checked to see if the below has subViews but didn't - In my current implementation it does anyway for (UIView *detectInteractView in interactiveView.detectionView.subviews) { CGRect interactRect; interactRect = [detectInteractView convertRect:[detectInteractView frame] toView:parentView]; if (CGRectIntersectsRect(viewRect, interactRect) == 1) { NSLog(@"collision detected"); [detectView setBackgroundColor:[UIColor blueColor]]; [detectInteractView setBackgroundColor:[UIColor blueColor]]; detectionCount++; } else { [detectView setBackgroundColor:[UIColor yellowColor]]; [detectInteractView setBackgroundColor:[UIColor yellowColor]]; } } } } } } // Logic if no items collided if (detectionCount == 0) { NSLog(@"Do something"); } } } } Now the method itself works to an extent but I don't think it's working with the nested values properly as the detection is off. A simplified version of this method works - Using CGRectIntersectsRect on the detectionView itself so I'm wondering if I'm looping through and checking the views correctly? I wasn't sure whether it was comparing in the same view but I suspect it is, I did modify the code slightly at one point, rather then comparing the values in self.view I took the viewController.detectView's UIViews into the interactiveView.detectView but the outcome was the same. It's rigged so the subviews change colour, but they change colour when they are not even touching, and when they do touch the wrong UIviews are changing colour Many thanks in advance

  • Memory leak found with clang but cant release and autorelease crashes

    - by Rudiger
    I have a class that builds a request based on a few passed in variables. The class also has all the delegate methods to receive the data and stores it in a property for the calling class to retrieve. When the class initializes it creates a connection and then returns itself: NSURLConnection *connection; if (self = [super init]) { self.delegate = theDelegate; ...some code here... connection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self startImmediately:YES]; } return self; So I can't release it normally and if I autorelease it crashes. Is it the job of the calling class to release? And if so does just releasing the initilised object also release connection or do you have to release it specifically? If so how would you? Thanks

  • addSubview animation

    - by Mike
    I have main UIView where I display different data. Then I put a button, which displays subview like this: - (IBAction) buttonClicked: (id) sender { UIView *newView = [[UIView alloc] initWithFrame:CGRectMake(25,25,50,20)]; UILabel *newLabel = [[UILabel alloc] initWithFrame:CGRectMake(25,25, 50,25)]; newLabel.text = @"some text"; [newView addSubview: newLabel]; [self.view addSubview: newView]; [newLabel release]; [newView release]; } newView appears fine, but it doesn't animate itself any way, it just appears immediately. How can I add some kind of animation when newView appears? Like zoom or slide down or something like that. Is there some simple code?

  • Best method of achieving bi-directional communication between Apple iPad "clients" and a Windows Ser

    - by user361910
    We are currently starting to build a client-server system which will see 10 or more Apple iPad client devices communicating to a central Windows server over a wireless LAN. We wanted to some existing plumbing (.NET remoting/WCF/web services/etc) that would allow us to implement a reliable, secure solution without having to start at a low level (e.g. sockets) and recreate the wheel. One of the major requirements that complicates this scenario is that unlike a traditional web service, the windows server needs to be able to arbitrarily notify the clients whenever certain events occur -- so it is not a simple request/response scenario like the web. Initially, we were going to use Windows clients, so our plan was to use the full-duplex mode of .NET WCF over HTTP|TCP. But now using the iPad, we don't have any of the WCF infrastructure. So my question is: what is the best way to allow an iPad and a Windows server to (securely) communicate over a LAN, with each device able to initiate communication to the other? Am I stuck writing low-level socket code? Thanks!

  • Freehand drawing with Quartz 2D

    I am trying to develop a simple freehand-drawing app for red-marking some of my images. Below is a method that is called from within the drawRect. I want to ask if there is a way to avoid add the path every time the path is redrawn? Also, the way the draw method is set up, the drawing gets a bit slow and choopy after a few seconds. How can I improve the smoothness of the drawn path? thanks -(void)freehandDraw:(CGContextRef)context inRect:(CGRect)rect { CGPathAddLineToPoint( path, NULL, drawTip.x, drawTip.y); CGContextAddPath( context, path); CGContextStrokePath(context); } // method

  • CGContext - PDF margin

    - by Manoj Khaylia
    Hi All I am showing PDF content on a view using this code using Quartz Sample // PDF page drawing expects a Lower-Left coordinate system, so we flip the coordinate system // before we start drawing. CGContextTranslateCTM(context, 0.0, self.bounds.size.height); CGContextScaleCTM(context, 1.0, -1.0); // Grab the first PDF page CGPDFPageRef page = CGPDFDocumentGetPage(pdf, pageNo); // We're about to modify the context CTM to draw the PDF page where we want it, so save the graphics state in case we want to do more drawing CGContextSaveGState(context); // CGPDFPageGetDrawingTransform provides an easy way to get the transform for a PDF page. It will scale down to fit, including any // base rotations necessary to display the PDF page correctly. CGAffineTransform pdfTransform = CGPDFPageGetDrawingTransform(page, kCGPDFCropBox, self.bounds, 0, true); // And apply the transform. CGContextConcatCTM(context, pdfTransform); // Finally, we draw the page and restore the graphics state for further manipulations! CGContextDrawPDFPage(context, page); CGContextRestoreGState(context); Using this all works fine I want to set the margin for the PDF context, bydefault it showing 50 px margin in every side.. I have tried CGContext methods but not got the appropriate one. Can any body help me regarding this Thanks Monaj
