    - by iSharreth
    I want to zoom an image in a scroll view. I used the below code. All are working fine, but the image is not zooming. Anyone please help. I am a beginner in iPhone app development. I had connected the delegate to files manager and set max zooming to 5 I can see the image. But how can I zoom it. IBOutlet UIScrollView *scrForImg; IBOutlet UIImageView *imgForScr; (void)viewDidLoad { [super viewDidLoad]; NSString *imagePath = [NSString stringWithFormat:@"myImage.png"]; imgForScr.image = [UIImage imageNamed:imagePath]; } -(UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView{ return imgForScr; }

  • NSNumberFormatter to display custom labels for 10^n (10000 -> 10k)

    - by Michele Colombo
    I need to display numbers on a plot axis. The values could change but I want to avoid too long numbers that will ruin the readability of the graph. My thought was to group every 3 characters and substitute them with K, M and so on (or a custom character). So: 1 - 1, 999 - 999, 1.000 - 1k, 1.200 - 1.2k, 1.280 - 1.2k, 12.800 - 12.8k, 999.999 - 999.9k, 1.000.000 - 1M, ... Note that probably I'll only need to format round numbers (1, 10, 1000, 1500, 2000, 10000, 20000, 30000, 100000, ...). Is that possibile with NSNumberFormatter? I saw that it has a setFormat method but I don't know how much customizable it is. I'm using NSNumberFormatter cause the graph object I use wants it to set label format and I want to avoid changing my data to set the label.

    - by Sheehan Alam
    I am trying to stream a video using MPMoviePlayerController but only audio is working.

  • Why doesn't Apple make private APIs inaccessible?

    - by Howiecamp
    If Apple doesn't want developers using private APIs in the iPhone SDK, why don't they do something like mark the classes and/or methods with whatever the Objective-C equivalent of C#'s "internal" keyword? If the APIs are spread amongst multiple binaries, Apple could refactor them into dedicated private-API-only binaries to make this easier for them.

  • How to hide the label (CCLabel) after a certain time in cocos2d ?

    - by srikanth rongali
    I added a label by using CCLabel to my layer. Now I want it do disappear after some time like (2sec). How can I make it to disappear? CCLabel *labelPerfectDraw = [CCLabel labelWithString:@"Perfect Draw" fontName:@"Marker Felt" fontSize:30 ]; labelPerfectDraw.color = ccc3(0x00, 0x00, 0xff); labelPerfectDraw.position = ccp(windowSize.width/2, windowSize.height/2+80); [self addChild:labelPerfectDraw]; I added label in above way. Please give me the idea how can I work on it?

  • How can I render a custom view in a UIScrollView at varying zoom levels without distorting the view?

    - by eczarny
    The scenario: I have a custom view (a subclass of UIView) that draws a game board. To enable the ability to zoom into, and pan around, the board I added my view as a subview of UIScrollView. This kind of works, but the game board is being rendered incorrectly. Everything is kind of fuzzy, and nothing looks right. The question: How can I force my view to be redrawn correctly ay varying scales? I'm providing my view with the current scale and sending it a setNeedsDisplay message after the scroll view is done zooming in/out, but the game board is still being rendered incorrectly. My view should be redrawing the game board depending on the zoom level, but this isn't happening. Does the scroll view perform a generic transformation on subviews? Is there a way to disable this behavior?

  • Getting Data For Webpages?

    - by fuzzygoat
    When looking to get data from a web page whats the recommended method if the page does not provide a structured data feed? Am I right in thinking that its just a case of doing an NSURLRequest and then hacking what you need out of the responseData(NSData*)? I am not too concerned about the implementation in Xcode, I am more curious about actually collecting the data, before I start coding a "hunt & peck" through a list of data. gary

  • What's the standard convention for creating a new NSArray from an existing NSArray?

    - by Prairiedogg
    Let's say I have an NSArray of NSDictionaries that is 10 elements long. I want to create a second NSArray with the values for a single key on each dictionary. The best way I can figure to do this is: NSMutableArray *nameArray = [[NSMutableArray alloc] initWithCapacity:[array count]]; for (NSDictionary *p in array) { [nameArray addObject:[p objectForKey:@"name"]]; } self.my_new_array = array; [array release]; [nameArray release]; } But in theory, I should be able to get away with not using a mutable array and using a counter in conjunction with [nameArray addObjectAtIndex:count], because the new list should be exactly as long as the old list. Please note that I am NOT trying to filter for a subset of the original array, but make a new array with exactly the same number of elements, just with values dredged up from the some arbitrary attribute of each element in the array. In python one could solve this problem like this: new_list = [p['name'] for p in old_list] or if you were a masochist, like this: new_list = map(lambda p: p['name'], old_list) Having to be slightly more explicit in objective-c makes me wonder if there is an accepted common way of handling these situations.

  • Refreshing a UITableView

    - by MihaiD
    I have a UITableView subclass and a UITableViewCell sublass that I'm using for cells. I'm bulding all my cells in advance and store them in an array from where I use them in cellForRowAtIndexPath. Aside from this I have a thread that loads some images in each cell, in the background. The problem is that the cells don't get refreshed as fast as the images are loaded. For example, if I don't scroll my table view, the first cells only get refreshed when all cells have been modified and the thread has exited. Any ideas on how I can effectively refresh my tableview/cell?

  • Changing UINavigationBar font in Swift

    - by dcgoss
    I have a UINavigationBar with a title in the middle. I have added a custom font ("Comic_Andy.ttf") to my app (I have checked info.plist to make sure it's listed, and I have checked the Copy Bundle Resources to make sure it has been added), and I would like the title of the UINavigationBar to be displayed in that font. From what I can gather it seems as though I'm supposed to use this in my ViewController: myNavigationBar.titleTextAttributes = [NSFontAttributeName: UIFont(name: "Comic_Andy", size: 22)] I placed that method in the viewDidLoad function of the ViewController. I have also tried this in the didFinishLaunchingWithOptions function of the AppDelegate: UINavigationBar.appearance().titleTextAttributes = [NSFontAttributeName: UIFont(name: "Comic_Andy", size: 22)] I am programming in Swift, in XCode 6 Beta 6. Many resources regarding this task have mentioned using a method called setTitleTextAttributes, which is nowhere to be seen. I can't figure it out for the life of me - I've probably spent close to 3 hours on it by now - I have checked every StackOverflow answer, every website, so please do not mark this as a duplicate. Many thanks in advance!

  • Accessing View in awakeFromNib?

    - by fuzzygoat
    I have been trying to set a UIImageView background color (see below) in awakeFromNib [imageView setBackgroundColor:[UIColor colorWithRed:0 green:0 blue:0 alpha:1.0]]; When it did not work, I realised that its probably because the view has not loaded yet and I should move the color change to viewDidLoad. Can I just verify that I have this right? gary

  • Assigning a selector via SEL type?

    - by fuzzygoat
    I just spotted the following in an online tutorial. It showed 001 as a method for assigning a selector, however I could not get this to work. Am I right in thinking that 001 is not right and 002 is the correct way, or am I doing something wrong with 001? // 001 SEL mySel = [self something]; // 002 SEL mySel = @selector(something); . -(void)something { NSLog(@"YAY"); } Gary

  • Why is there no autorelease pool when I do performSelectorInBackground: ?

    - by Thanks
    I am calling a method that goes in a background thread: [self performSelectorInBackground:@selector(loadViewControllerWithIndex:) withObject:[NSNumber numberWithInt:viewControllerIndex]]; then, I have this method implementation that gets called by the selector: - (void) loadViewControllerWithIndex:(NSNumber *)indexNumberObj { NSAutoreleasePool *arPool = [[NSAutoreleasePool alloc] init]; NSInteger vcIndex = [indexNumberObj intValue]; Class c; UIViewController *controller = [viewControllers objectAtIndex:vcIndex]; switch (vcIndex) { case 0: c = [MyFirstViewController class]; break; case 1: c = [MySecondViewController class]; break; default: NSLog(@"unknown index for loading view controller: %d", vcIndex); // error break; } if ((NSNull *)controller == [NSNull null]) { controller = [[c alloc] initWithNib]; [viewControllers replaceObjectAtIndex:vcIndex withObject:controller]; [controller release]; } if (controller.view.superview == nil) { UIView *placeholderView = [viewControllerPlaceholderViews objectAtIndex:vcIndex]; [placeholderView addSubview:controller.view]; } [arPool release]; } Althoug I do create an autorelease pool there for that thread, I always get this error: 2009-05-30 12:03:09.910 Demo[1827:3f03] *** _NSAutoreleaseNoPool(): Object 0x523e50 of class NSCFNumber autoreleased with no pool in place - just leaking Stack: (0x95c83f0f 0x95b90442 0x28d3 0x2d42 0x95b96e0d 0x95b969b4 0x93a00155 0x93a00012) If I take away the autorelease pool, I get a whole bunch of messages like these. I also tried to create an autorelease pool around the call of the performSelectorInBackground:, but that doesn't help. I suspect the parameter, but I don't know why the compiler complains about an NSCFNumber. Am I missing something? My Instance variables are all "nonatomic". Can that be a problem? UPDATE: I may also suspect that some variable has been added to an autorelease pool of the main thread (maybe an ivar), and now it trys to release that one inside the wrong autorelease pool? If so, how could I fix that? (damn, this threading stuff is complex ;) )

  • iPhone SDK: Orientation (Landscape and Portrait views)

    - by domness
    Okay, I've got my normal app which is in portrait mode. I can force my app to go to landscape mode for a view (using navigationcontroller and viewcontroller) like this: - (void)viewWillAppear:(BOOL)animated { [[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight]; } But then when I go back to the main menu (tableview) it goes straight back to portrait. I try this code: - (void)viewWillAppear:(BOOL)animated { [[UIDevice currentDevice] setOrientation:UIInterfaceOrientationPortrait]; } But that doesn't work.. Any ideas?

  • MKAnnotationView for userLocation pin iPhone

    - by Mauricio Galindo
    I have an application that uses MKMapView and at some point in the app I need to remove all the current pins in the map using [mapView removeAnnotations:mapView.annotations] And then I want to show again the current user location mapView.showUserLocation = YES But I can only make it reappear as a regular pin, because the userLocation view class its not public so I cant return views of that type. Here is my code - (MKAnnotationView *)mapView:(MKMapView *)theMapView viewForAnnotation:(id <MKAnnotation>)annotation MKPinAnnotationView* annView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:@"currentloc"]; if (!annView) { MKPinAnnotationView *annView=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"currentloc"]; annView.pinColor = MKPinAnnotationColorRed; annView.animatesDrop=TRUE; annView.canShowCallout = YES; annView.calloutOffset = CGPointMake(-5, 5); if ([annotation isKindOfClass:[DraggableAnnotationAM class]] ) annView.draggable = YES; return annView; } else { if ([annotation isKindOfClass:[DraggableAnnotationAM class]] ) annView.draggable = YES; annView.annotation = annotation; return annView; } Also I have found through reflection that MKUserLocationView is the class that is used to display the current location, but because its not public its not safe to use and my app keeps crashing and Im sure theres a easier way. Is it possible to do what I want, or should I just never remove the user location annotation of the mapView? Thanks in advance

  • Calling method on category included from iPhone static library causes NSInvalidArgumentException

    - by Corey Floyd
    I have created a static library to house some of my code like categories. I have a category for UIViews in "UIView-Extensions.h" named Extensions. In this category I have a method called: - (void)fadeOutWithDelay:(CGFloat)delay duration:(CGFloat)duration; Calling this method works fine on the simulator on Debug configuration. However, if try to run the app on the device I get a NSInvalidArgumentException: [UIView fadeOutWithDelay:duration:]: unrecognized selector sent to instance 0x1912b0 *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIView fadeOutWithDelay:duration:]: unrecognized selector sent to instance 0x1912b0 It seems for some reason UIView-Extensions.h is not being included in the device builds. What I have checked/tried I did try to include another category for NSString, and had the same issue. Other files, like whole classes and functions work fine. It is an issue that only happens with categories. I did a clean all targets, which did not fix the problem. I checked the static library project, the categories are included in the target's "copy headers" and "compile sources" groups. The static library is included in the main projects "link binary with library" group. Another project I have added the static library to works just fine. I deleted and re-added the static library with no luck -ObjC linker flag is set Any ideas? nm output libFJSCodeDebug.a(UIView-Extensions.o): 000004d4 t -[UIView(Extensions) changeColor:withDelay:duration:] 00000000 t -[UIView(Extensions) fadeInWithDelay:duration:] 000000dc t -[UIView(Extensions) fadeOutWithDelay:duration:] 00000abc t -[UIView(Extensions) firstResponder] 000006b0 t -[UIView(Extensions) hasSubviewOfClass:] 00000870 t -[UIView(Extensions) hasSubviewOfClass:thatContainsPoint:] 000005cc t -[UIView(Extensions) rotate:] 000002d8 t -[UIView(Extensions) shrinkToSize:withDelay:duration:] 000001b8 t -[UIView(Extensions) translateToFrame:delay:duration:] U _CGAffineTransformRotate 000004a8 t _CGPointMake U _CGRectContainsPoint U _NSLog U _OBJC_CLASS_$_UIColor U _OBJC_CLASS_$_UIView U ___CFConstantStringClassReference U ___addsf3vfp U ___divdf3vfp U ___divsf3vfp U ___extendsfdf2vfp U ___muldf3vfp U ___truncdfsf2vfp U _objc_enumerationMutation U _objc_msgSend U _objc_msgSend_stret U dyld_stub_binding_helper
