  • Using CCSpriteFrameCache without CCSpriteBatchNode

    - by AwDogsGo2Heaven
    I want to know if there is any benefiting caching a sprite sheet and accessing the sprite by frame without using the CCSpriteBatchNode? In some parts of my game the sprite batch node is useful because there is a lot on the screen, however on another part its not, because there are just a few things, and there are requirements for layers so CCSpriteBatchNode wouldn't be useful. However, for the sake of consistency I would like to use Sprite Sheets for all my sprites, and so was beginning to wonder if I would still receive any benefit from it? (Or worse that it could some how be slower...)

  • SDK 3.2 - Trigger video from UIScrollView Subview (Audio but no video)

    - by stalure
    I am having a hard time getting video to play in an application that I am working on and I think the answer has to do with the views and view controllers. I have the flow depicted below. When the button is clicked, the audio from the video is playing, but nothing is displayed on screen. Anyone have any ideas? -(IBAction) playMovie { Play Movie Code } ViewController UIScrollView UIView UIButton - (playMovie)

  • Processing a method after the view has loaded..

    - by Susanth
    Hi ! I have implemented a subview which is supposed to load immediately when I click a button in the parent view. After loading the subview(which is basically holding an activityindicator), the program is supposed to process a method(which gets data from a server, so takes time) in it. However, I am unable to do it. What happens now is, when I click the button on the parent view, it processes the method first and only after that does the subview load on screen. Why is this so? Is there any specific functions I could use to make my method load only after the view has loaded?

  • How to create a timer the right way?

    - by mystify
    I always have an class which needs to set up a timer for as long as the object is alive. Typically an UIView which does some animation. Now the problem: If I strongly reference the NSTimer I create and invalidate and release the timer in -dealloc, the timer is never invalidated or released because -dealloc is never called, since the run loop maintains a strong reference to the target. So what can I do? If I cant hold a strong ref to the timer object, this is also bad because maybe I need a ref to it to be able to stop it. And a weak ref on a object is not good, because maybe i'm gonna access it when it's gone. So better have a retain on what I want to keep around. How are you guys solving this? must the superview create the timer? is that better? or should i really just make a weak ref on it and keep in mind that the run loop holds a strong ref on my timer for me, as long as it's not invalidated?

  • UIView animation cancels previous animation?

    - by user281300
    Hi I have an NSTIMER that counts the time, and on t = 10, it fires an animation but during that time it might happen that another animation is running. This causes the previously running animation to cut off. Any idea? i thought UIVIEW animations were ran in diff threads. I cannot use a willstop selector here since t = 10 might happen while another animation is running and might not have ended yet.

  • How to make paging off of vertical direction in WWDC2010 photoScroller.

    - by user357383
    In WWDC2010 sample code "photoScroller", in landscape mode, I want to change image size to 480*751. But there is vertical paging in this mode. In this sample, zooming mode doesn't have vertical paging. So I want to same as this. Please teach me how to fix this sample code. I changed this code as follows. - (CGRect)frameForPagingScrollView { CGRect frame = CGRectMake(0, 0, 480, 751); frame.origin.x -= PADDING; frame.size.width += (2 * PADDING); return frame; } Thank you

  • Any point in subclassing UIButton to create a custom looking button?

    - by glitch
    I want to create a set of buttons that would work and feel very much like the Metro-style tiles that are available on Windows Phones. I would like to allow the user to tap them to access their underlying functionality (open a modal or something or that sort). I'm concerned that subclassing UIButton will not get me there. I need square corners and dynamic content inside the tiles themselves. The posts I've found around SO seem to suggest that subclassing a UIButton would not be a good idea for several reasons and that I should instead use UIView. That reply is from 2010, and I have no idea if in the 2+ years since then there have been considerable changes to how one would achieve that effect. Most users these days will have iOS 5.1+ if not 6.0 soon. Let's say I do go the UIView route. Should I implement UIResponder's touch events or should I instead go the UITapGestureRecognizer route? What's the better practice in 2012? Thank you!

  • Why Duplicate the “Release” configuration to "Disctribution"?

    - by Horace Ho
    On the Apple guide, there is a step before building the AppStore version: Open the Xcode project and Duplicate the “Release” configuration in the Configurations pane of the project's Info panel. Rename this new configuration “Distribution”. Why this step is needed? Can I skip this step and use the "Release" configuration to build the final version for AppStore?

  • Make UIViewController outside Navigation Controller

    - by user1447316
    i have a question for you. I'm working on this app that has a walkthrough/tutorial screens and also login ones. On each of this screens there is a button to skip this part and go directly to use the app, without completing the registration (you know, so that people can test it before signing-in). As you can see i'm using Storyboards. The NowPlaying04 ViewController is actually the app itself. Obviously, when the user will be a registered one, i should also be able to jump right back to that screen, skipping the walkthrough and signin process. The first question is: how is the best way to structure this? The second quesion is: how i can make a ViewController outside that Navigation controller. Cause as you can see now, the NowPlaying04 ViewController inherits the top navigation bar. Which is a thing that i don't want. I don't need that. I hope that you have understood my question. I'll appreciate any help. Programmatically or by dragging stuff around, i'm ok with all the solutions. The important thing is that it works correctly! :-)

  • Application frame leaves blank line at the top

    - by iFloh
    Any clues why my programmatically defined UIScrollView (using the application frame) always leaves an empty space at the top (below the navigationBar) of 20 pixels. How can I close that? UIScrollView *vScrollView = [[UIScrollView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; vScrollView.backgroundColor = [UIColor redColor]; How do I need to call the application frame size to avoid that gap?

  • Incorrect rotation of a view controller in iOS 6

    - by XenElement
    In my app I've been using the now deprecated shouldAutoRotateToFace method. Now when using the iOS 6 simulator, all of my subviews are rotated to portrait orientation while the device is in landscape. Does anyone have any idea what could cause this? I've already tried replacing should autorotate in my main view controller with the supportedOrientations method (or whatever it is that you're now supposed to use instead).
