  • UIButton Transition Curl Up problem

    - by Neurofluxation
    Hello again SO peeps! Basically, I am trying to UIViewAnimationTransitionCurlUp a UIButton. The animation works perfectly but the button stays there. i.e. The button curls up, but there is another instance of the button still underneath. My code as follows: [UIButton beginAnimations:nil context:nil]; [UIButton setAnimationDuration:0.5]; [UIButton setAnimationBeginsFromCurrentState:YES]; [UIButton setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view cache:YES]; [UIButton commitAnimations];

What I did Create a project (Window-Based) Add 3 child classes (Window-Based too) Add a Tab Bar Controller to MainWindow.xib For each view under Tab Bar Controller, the 'Class', 'Name', 'Title' and 'NIB Name' are all set to connect to the corresponding class Add @class, IBOutlet are done in AppDelegate.h and AppDelegate.m In didFinishLaunchingWithOptions, I called [window addSubView: tabBarController.view]; Save and Run -- Tab Bar with 3 items can be seen But ... the 3 child views ARE NOT LOADED and SHOWN ... :( Anything that I missed ?

  • touchesMoved QuartzDemo application

    - by BittenApple
    I am modifying the QuartzDemo application to include swipe detection while UIView is active (a PDF page being displayed in it via Quartz). This will not work, the event never gets to the QuartzView.m because it sits under scrollview? touchesBegan works fine and I can use single tap. How can I go about with catching touchesMoved while PDF page is being displayed? I need a simple example with code that does nothing on touchesMoved, I'll build up on that later. Please keep in mind that I still want to use the UIScrollview as it is and show PDF content based on selection in that scrollview.

  • Problem in getting response from webserver

    - by Amarpreet
    Hi guys I am sending data to webserver in the Querystrings by creating URL dynamically. When I view that URl in UIAlertView it shows me correct one. And when i try to get response using NSURL code, it does not respond. Below is the code. NSString *uu = @"http://www.zenhomeenergy.com/ZenIphoneServUpdate.aspx?CustomerID=12&FirstName=Andrew&LastName=Turner&State=SA&Street=60 Highfiled Drive Hillbank no phone number&PostCode=5112&Email= &Mobile= &HomePhone= &WorkPhone= &PrimaryResidence=True&HomeOwner=True"; NSString *text = [NSString stringWithContentsOfURL:[NSURL URLWithString:uu]]; if(text) { if([text isEqualToString:@"Success."]) { textView.text = [textView.text stringByAppendingString:@"Success.\n"]; } else { textView.text = [textView.text stringByAppendingString:@"Failed.\n"]; } } If you try putting the above URL into browser it says "Success." But the code above doesnot work. Please Help.

  • View controller/NIB architecture for non-navigation application with transitions?

    - by Ben
    I'm tinkering with an app that doesn't use the UINavigation root view control system, so I don't have natural ownership for each app "view". I essentially have two basic views, a document list view, and a document edit view. I'm playing with UIView animation for getting from a selected document to the edit view. I also have a toolbar that exists in both "views". Because I don't have UINavigation running the show for me, I have a tendency to just throw more and more stuff into one NIB and one view controller that owns the whole container. But now I'm trying to figure out how to segue from the document list view to the edit view if the edit view lives inside a different NIB, preserving the toolbar too. Anyone have thoughts or experience on app structures like this? I find the docs lacking on best practices around code/UI structure for anything except trivial one-screen apps or full-on navigation apps. Thanks!

  • How to change the UIImageView image content by code?

    - by Tattat
    I use this to assign image: UIImage *img = [UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"myImage" ofType:@"png"]]; CGRect cropRect = CGRectMake(175, 0, 175, 175); CGImageRef imageRef = CGImageCreateWithImageInRect([img CGImage], cropRect); imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 175, 175)]; imageView.image = [UIImage imageWithCGImage:imageRef]; [self addSubview:imageView]; CGImageRelease(imageRef); Now, I want to change the image from myImage to myImage2, so I do that: UIImage *img = [UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"myImage2" ofType:@"png"]]; CGRect cropRect = CGRectMake(175, 0, 175, 175); CGImageRef imageRef = CGImageCreateWithImageInRect([img CGImage], cropRect); imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 175, 175)]; imageView.image = [UIImage imageWithCGImage:imageRef]; [self addSubview:imageView]; It works, but not the way I want, I want to change the image, not add a imageView on top of the pervious one. How can I modify my code? thx u.

  • Message sent to deallocated instance which has never been released

    - by Jakub
    Hello, I started dealing with NSOperations and (as usual with concurrency) I'm observing strange behaviour. In my class I've got an instance variable: NSMutableArray *postResultsArray; when one button in the UI is pressed I initialize the array: postResultsArray = [NSMutableArray array]; and setup the operations (together with dependencies). In the operations I create a custom object and try to add to the array: PostResult *result = [[PostResult alloc] initWithServiceName:@"Sth" andResult:someResult]; [self.postResultsArray addObject:result]; and while adding I get: -[CFArray retain]: message sent to deallocated instance 0x3b40c30 which is strange as I don't release the array anywhere in my code (I did, but when the problem started to appear I commented all the release operations to be sure that they are not the case). I also used to have @synchronized section like below: PostResult *result = [[PostResult alloc] initWithServiceName:@"Sth" andResult:someResult]; @synchronized (self.postResultsArray) { [self.postResultsArray addObject:result]; } but the problem was the same (however, the error was for the synchronized operation). Any ideas what I may be doing wrong?

  • AVAudioPlayer lag when calling play

    - by joec
    I have set up an AVAudioPlayer object in viewDidLoad, as per the Apple guidelines, calling prepareToPlay as the last line in viewDidLoad (i have tried in awakeFromNib also). When i press my play button, there is a pause, as it would appear to load the file, then it plays. In audioPlayerDidFinishPlaying, i reload the player with a different sound, and when clicking play for a second time, the file plays instantly. What would cause the player to lag on the first play? Thanks.

  • Add subview to another view

    - by Martol1ni
    With two ViewControllers, MyView 1 and MyView 2, is there possible to add a subview to MyView2 from MyView1.m? I have tried: MyView2 * screen = [[MyView2 alloc]initWithNibName:nil bundle:nil]; [screen.view addSubView:mySubView]; But my new instance of MyView 2 has no connection to the 'visible' ViewController on MyView2, right? To clarify, the ViewController that is showing, is MyView1. I want MyView1 to be able to add a subview to the MyView2 view. Thanks

  • 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.

  • AvoidXferMode Tolerance

    - by kayahr
    I have a problem with the following code: protected void onDraw(Canvas canvas) { Paint paint = new Paint(); // Draw a blue circle paint.setColor(Color.BLUE); canvas.drawCircle(100, 100, 50, paint); // Draw a red circle where it collides with the blue one paint.setXfermode(new AvoidXfermode(Color.BLUE, 0, Mode.TARGET)); paint.setColor(Color.RED); canvas.drawCircle(50, 50, 50, paint); } According to the API documentation of AvoidXfermode the tolerance value 0 means that it looks for an EXACT color match. This should work here because I specify the same color as I used for drawing the first circle. But the result is that the red circle is not drawn at all. When I use a tolerance value of 255 instead then it works (red circle is drawn where it collides with the blue one) but that sounds wrong because with such a high tolerance I think it should draw the circle EVERYWHERE. So what's wrong here? API Documentation? Android? Me?
