Every body i am integrating icarousel with cocos2d using uiviewwrapper and after that i have done with icarousel is working fine in simulator but on ipad it make some problem that is its first and last options are responding normally as it does but in between options uibuttons are not responding when selected and thay are working when that are at some specific angle not in front view .I have searched alot but i could not find any solution for that as there is not a single warning or error when app builds.
All suggestions will be welcomed. Thanks

In the appDelegate function delete the line
if( ! [CCDirector setDirectorType:kCCDirectorTypeDisplayLink] )
[CCDirector setDirectorType:kCCDirectorTypeDefault];
and replace the same with
[CCDirector setDirectorType:kCCDirectorTypeDefault];
setting the [CCDirector setDirectorType:kCCDirectorTypeDisplayLink] will cause unexpected behaviour in iCarousel.
It's possible that Cocos may be interfering with the UITapGestureRecognizer that iCarousel uses to intercept taps and forward them to the item views.
That would explain why you can tap the side views but not the frontmost view, since it's gestures are treated differently.
Try poking around in the code and adding some breakpoints to the gesture handling logic to see if you can see where it's failing.
Alternatively, send me a working code example and I'll take a look.

I'm writing an app in Swift 2.0. The app works fine in every aspect, beside one.
When I tilt the screen of both device and emulator the orientation change animation is missing. Instead of a smooth rotation I get a clunky orientation change. Portrait -> Landscape. Nothing in between.
Giving the fact that the animation should be the default, I would like to know if anybody knows the possible solution to this problem. I searched everywhere and apparently nobody has this problem, instead people try to disable that animation!
After some tests and thanks to Zell.B, I moved the code from didFinishLaunchWithOptions to applicationDidBecomeActive and everything works fine.
Deleting the applicationDidFinishLaunching method from the app delegate class can also cause the lack of animation problem. Adding it back in can fix it.
I'm coding a video processing app and was just about to submit it to the app store when ios 8.1 came out. I updated my iPhone as well as XCode and all hell broke loose. In my simple single viewcontroller interface nothing is rotating anymore except for the statusbar, which also doesn't get automatically hidden anymore in landscape mode...
I figured it was because I was using the deprecated willAnimateRotationToInterfaceOrientation: for what little custom rotation actions I had, so I implemented traitCollectionDidChange: and viewWillTransitionToSize: to specs instead. However viewWillTransitionToSize never gets called in my app and traitCollectionDidChange: is only called once, at startup. The device simply isn't telling the app that the device has rotated.
After googling I've also tried using name:UIDeviceOrientationDidChangeNotification. At least my selector does get called for that one but I don't know how to manually handle all rotation.
My didFinishLaunching... and viewDidLoad are very simple. alloc UIWindow, storyboard, set my viewcontroller from there, make it rootviewcontroller, makekeyandvisible. All based on one of Apple's AVFoundation demo apps.
Then in didload I add some subviews and a toolbar etc, nothing out of the ordinary and obviously it did work on 8.0 and 8.0.2 on all kinds of devices as well as the 7.1 simulator etc. Still runs flawlessly on my iPad with 8.0.2... Reason I haven't posted any code is I'm 100% sure everything is correct on that end.
Main weird thing is I can't seem to find anyone with this problem.
No errors in console or elsewhere either.
Does anyone have any idea of what might be causing this? I didn't think a point release would make such massive differences and again, no one else seems to be having this. Could it be an issue/bug in the actual storyboard file?
And, mainly, since I can get rotation notifications through UIDeviceOrientationDidChangeNotification, how do I manually handle all rotation/resizing stuff? I have been looking all over for answers but to no avail and am out of time to spend on this project currently :(
Cheers!
alloc'ing UIWindow will be the problem.
First, Make sure your navigation controller (or whatever you're using) is set as "Initial View Controller" in your storyboard.
Secondly, in your AppDelegate.m file, remove any references to UIWindow and rootViewController that appear in application didFinishLaunchingWithOptions. In my case, removing the following two lines fixed my issues.
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[self.window makeKeyAndVisible];
You also don't need to set the window's rootViewController if using storyboards.
They're simply not needed when using storyboards, but until 8.1 there was never any harm using them. It took my 2 days to figure this out, so hopefully it will help you and others too.
Every time when we add UIImageView or simple UIView with some custom CALayer objects added to "layer" property to view hierarchy, there are some different scenarios:
1) all images (in uiimageviews and calayer) are drawn with random delay
2) some images are drawn, but some not, when we perform a simple touch event anywhere - they appear
3) some images are not drawn and they won't appear after simple touch events, the only way make them to appear is to minimize the app and to expand it again.
The last case appears much less than two others. That problem occurs only on iOS7, iOS 4.3-6.1 is totally OK. We have viewed a lot of possible solutions but they were pretty primitive and none of those helped.
Any help would be appreciated! Thanks in advance!
we solved the problem. For everyone, who has the same problem, - all you need is to create CALayer and UIImageView objects on main thread, while UIImage objects still could be created in background thread. All these fixes are needed only in iOS 7
So I'm creating and showing a custom window in my iOS app because I'm writing a dynamic alert view that also functions like a growl/toast alert. It works AWESOMELY in ios6 (Hopefully I can open source this baby and you can all check it out)
But anyway, when I run this in ios5, the window that my alerts exist on doesn't seem to rotate with the device/simulator. No matter what, my custom window stays in portrait mode.
The UIWindow is just a UIView subclass, so there's no nice 'shouldRotate' delegate method.
I'm kinda stumped on why this is happening in ios5 but not 6. Any help would be GREATLY appreciated ^_^
My window has a rootviewcontroller, which I completely forgot about. I just needed to implement
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{
return YES;
}
To get it to work.
:-D
It's usually not recommended two use multiple instances of UIWindow in one iOS app. The only valid reason to do so is to support external screens. You should use a UIView instead, ideally managed by a UIViewController.
I assume, (since you didn't provide any code, I can only assume) the reason why your window doesn't 'rotate' is, that it's simply not getting any notifications about device rotation. Only the keyWindow receives them by default.
I would highly recommend to redesign your app to use a properly managed UIView instead. If you desperately don't want that for some reason, you would have to register your instance of UIWindow to receive the UIDeviceOrientationDidChangeNotification and then (in the handler) evaluate what the new orientation is and change the window's frame accordingly (plus maybe other things that need to be done in response to the orientation change)
I am using a uiscrollview in my cocos2d project, using modification of some cocos2d files and the great CCScrollView class I got from a SO link. It is working fine but when I move to a next scene, the new scene is not responding to touches (whereas it was working fine before).
I am using iOS 5.1 & cocos2d 2.x.
Any suggestions?
Ok, you need to do this:
[aScrollView removeFromSuperview];
I'm not quite sure why since in the dealloc of CCScrollView you have:
[self removeFromSuperview];
I guess its being retained somehow? Anyway, it works.
