  • Is there an optimal way to render images in cocoa? Im using setNeedsDisplay

    - by Edward An
    Currently, any time I manually move a UIImage (via handling the touchesMoved event) the last thing I call in that event is [self setNeedsDisplay], which effectively redraws the entire view. My images are also being animated, so every time a frame of animation changes, i have to call setNeedsDisplay. I find this to be horrific since I don't expect iphone/cocoa to be able to perform such frequent screen redraws very quickly. Is there an optimal, more efficient way that I could be doing this? Perhaps somehow telling cocoa to update only a particular region of the screen (the rect region of the image)?

  • Formula for producing a CGRect for a UIScrollView, that displays a UIImage in scaled to fit way

    - by RickiG
    Hi I am loading in images with varying sizes and putting them in UIScrollViews, all the images are larger than the UIScrollView. The user can scroll and zoom as they please, but initially I would like for the image to be centered and scaled so the largest side of the image aligns with the edge of the scrollView, i.e. if the picture is in landscape I would like to size and scale it so that the left and right side goes all the way to the edge of the UIScrollVIew and vice versa I found a formula in a utility function in the Programming guide but it does not quite fit my needs. My approach is to use: CGrect initialPos = ? [self.scrollView zoomToRect:initialPos animated:YES]; I know the size of my scrollView and the size of my image, what I need to figure out is the scale and CGRect to apply to the scrollView to center and size my image. Hope someone can help out:) Thanks

  • How to remove an observer for NSNotification in a UIView?

    - by sudo rm -rf
    Hello! I've added an observer in a custom UIView I've created under initWithFrame:. [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(updateZipFromLocation:) name:@"zipFoundFromLocation" object:nil]; The problem is, this view is a subview. When the view is loaded again, it calls the initWithFrame message again, thus adding two observers and so on. How can I remove the observer when the view is going to disappear? Since it is a UIView, it says that viewWillDisappear:(BOOL)animated is not a valid method. Any ideas?

  • Animating UIImageView iPhone

    - by Fred Dpn
    Hi, i'm having trouble about animating an Image in a UIImageView. I've created an image view in interface builder and linked it to its iboutlet. Here is my code. @interface Game : UIViewController <UIAccelerometerDelegate>{ IBOutlet UIImageView *diying; } @property (nonatomic, retain) UIImageView *diying; In the viewDidLoad method i've written this code NSArray * imageArray = [[NSArray alloc] initWithObjects: [UIImage imageNamed:@"Die1.gif"], [UIImage imageNamed:@"Die2.gif"], [UIImage imageNamed:@"Die3.gif"], [UIImage imageNamed:@"Die4.gif"], nil]; diying.animationImages = imageArray; diying.animationDuration = 1.1; diying.contentMode = UIViewContentModeBottomLeft; [diying startAnimating]; [super viewDidLoad]; which is a adaptation of what i've found here : http://icodeblog.com/2009/07/24/iphone-programming-tutorial-animating-a-game-sprite/ NB : those .gif files are simple images and are not animated. I did the tutorial and it worked fine but i can't figure out why it my adaptation doesn't work !

  • Determine when a NSOpenPanel will close

    - by Martin
    I'm trying to determine when an NSOpenPanel is closing before it actually closes. I need to do this so I can overlay another window with a screenshot of the open panel on top of it to be animated. Unfortunately, all the notifications that you seem to be able to access seem to fire AFTER the window's already been closed. This leads to a jarring stutter before you start your transition. I've tried: - using NSWindow delegate methods on the open panel (apparently, none of the NSWindow delegate methods work) - monitoring panel:userEnteredFilename:confirmed: (not called) - showing the dialog with a callback (callback happens AFTER the panel disappears)

  • Why am I getting this warning about my app delegate and CLLocationManageDelegate?

    - by Dan Ray
    Observe this perfectly simple UIViewController subclass method: -(IBAction)launchSearch { OffersSearchController *search = [[OffersSearchController alloc] initWithNibName:@"OffersSearchView" bundle:nil]; EverWondrAppDelegate *del = [UIApplication sharedApplication].delegate; [del.navigationController pushViewController:search animated:YES]; [search release]; } On the line where I get *del, I am getting a compiler warning that reads, Type 'id <UIApplicationDelegate>' does not conform to the 'CLLocationManagerDelegate' protocol. In fact, my app delegate DOES conform to that protocol, AND what I'm doing here has nothing at all to do with that. So what's up with that message? Secondary question: sometimes I can get to my navigationController via self.navigationController, and sometimes I can't, and have to go to my app delegate's property to get it like I'm doing here. Any hint about why that is would be very useful.

  • navigation between screens Iphone programming

    - by Sephy
    Hi, I don't know if my question will be clear or not, but i'm starting basic stuff with iphone programming, and i'm trying to understand how to go from a screen to another. lets say i have a screen with a "next page" button and another page with a "return" button. I have a general idea of how to do this, but I don't know how to put it together. I think I need an IBAction method for each button, and in each method a navigation controller with pushViewController. So far, i've tried the following code, but even if it compiles properly and runs when i push the button, there is no change of screen... -(IBAction) toNext(id)sender{ NSLog(@"before code"); NextViewController *nvc = [[NextViewController alloc] initWithNibName:@"NextView" bundle:nil]; [self.navigationController pushViewController:nvc animated:YES]; [nvc release]; NSLog(@"after code"); } If someone had a nice tuto for me, it could be of some help... thx

  • iPhone SDK - keep data in modal view

    - by swalkner
    Hi all, I've got a modal view loaded the following way: ModalViewController *modalController = [[ModalViewController alloc] initWithNibName:@"ModalViewController" bundle:nil]; searchController.delegate = self; [self.navigationController presentModalViewController:modalController animated:YES]; [modalController release]; When the modal view appears, "viewDidLoad" is called. When I dismiss the modal view via [self.navigationController dismissModalViewControllerAnimated:YES]; the method "viewDidUnload" ISN'T called, but the next time I let the modal view appear, "viewDidLoad" is called again. My problem now is that I'm creating an NSArray in the modal view's "viewDidLoad" - and as I'm fetching the data from the web, I would like to do it only once. But this way, it's fetched every time... Any hints how I could achieve that the data is only fetched once? I would really like to do it in the modal view and not in the parent and provide the array as parameter to the modal view... Thanks!

  • a question about flex preloaders

    - by dubbeat
    Hi, I'm moving to a pure as3 environment into flex and I have a question about preloaders. For one of my apps in particular when the swf loaded I would add a screen with an animated preloader. Then at a particular point in my code when I know all of my xml has been parsed, UI built and all initiliztion done I dispatch a "done" event which removes the preloader. How can I achieve this is flex? I've only ever really seen flex preloaders that are percentage based which I believe represent the actual loading of the swf itself?

  • UIView animation

    - by iphonedevnoob
    I have a UIView(first view) on top of which I would like to display another UIView(second view). I display the second view using animation which causes the second view to be displayed for about 3/4 of the iPhone screen. The first view is visible underneath the animated second view. I would like to make changes to the first view as the second view is displayed. Any ideas on how I can achieve this. Right now, the animation completes, the second view is displayed and then I can change the first view. I would like to change the layout of the first screen as the second screen is being displayed. Any help is much appreciated.

  • NavigationController does not set view properties correctly when pushed

    - by Sheehan Alam
    I have a UITabBarControllerDelegate that pushes a new view controller when a certain tab is pressed: - (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController { MyView* myView = [[[MyView alloc] initWithNibName:@"MyView" bundle:nil]autorelease]; if([self.tabBarController.selectedViewController.title isEqualToString:@"Friends"]){ NSLog(@"Clicked Friends"); myView.reloadFriends = TRUE; [self.navigationController myView animated:YES]; } } However, if I change my code to set the tabbar's selected view controller to myView everything works, but I don't get my navigation bar: if([self.tabBarController.selectedViewController.title isEqualToString:@"Friends"]){ NSLog(@"Clicked Friends"); myView.reloadFriends = TRUE; self.tabBarController.selectedViewController = myView; } How can I set the reloadFriends property in MyView and have the navigation bar at the top?
