I'm make an iPhone app, in this app the user can send a SMS.
On my iPhone 4 is my screen perfect, but on my iPhone 5 i get a blank box.

Follow these steps if u failed to.
Are you using the latest version of Xcode if not download from here.
You can use the Auto layout feature and create the design the using iPhone 5 screen resolution and it will work for the both 4" and 3.5" devices, but in this case you should have a enough knowledge of layout manager.
Set a 4-inch launch image for your app. This is how you get 1136 px screen height (without it, you will get 960 px with black margins on top and bottom), To adapt your app to the new taller screen, the first thing you do is to change the launch image to: Default-568h#2x.png. Its size should be 1136x640 (HxW). Yep, having the default image in the new screen size is the key to let your app take the whole of new iPhone 5's screen..
Hopefully everything should work if you had set auto resizing masks properly.
If you didn't, adjust your view layouts with proper auto resizing masks or look into Auto Layout if you only want to support iOS 6 going forward.
If there is something you have to do for the larger screen specifically, then it looks like you have to check height of [[UIScreen mainScreen] bounds] (or applicationFrame, but then you need to consider status bar height if it's present) as there seems to be no specific API for that.
for instance:
CGRect screenBounds = [[UIScreen mainScreen] bounds];
if (screenBounds.size.height == 568) {
//iPhone 4 specific
} else {
//iPhone 5 specific
}
Hope this solves your problem.

This happens on Android only. Videos work properly on iOS and Simulator.
The problem is that when my videos are loaded into the MediaPlayer, the displayed frame is and remains completely black. After pressing play, the video displays correctly. By pressing pause, the frame on which the pause occurred is shown correctly. However, if the app switches to background and then back to foreground, the paused video goes back to completely black.
How can I fix this problem?
The relevant part of my code is more or less as follows:
Media video = MediaManager.createMedia(videoFilePath, true, () -> {
Runnable callback = runOnVideoCompletion.get();
if (callback != null) {
callback.run();
}
});
video.setNativePlayerMode(false);
video.prepare();
MediaPlayer mediaPlayer = new MediaPlayer(video) {
#Override
public Dimension getPreferredSize() {
return new Dimension(size, size);
}
};
mediaPlayer.setHideNativeVideoControls(true);
mediaPlayer.setMaximize(false);
mediaPlayer.hideControls();
mediaPlayer.setAutoplay(false);
Container mediaPlayerCnt = new Container(new LayeredLayout(), "NoMarginNoPadding") {
#Override
public Dimension getPreferredSize() {
return new Dimension(size, size);
}
};
mediaPlayerCnt.add(mediaPlayer);
[...]
UPDATE: please see the comment Reduce the impact of videos in memory to prevent crashes, since there is a better approach than the solution I proposed here.
While waiting for a proper solution, I came up with a workaround that seems to solve the problem perfectly on my Android phone.
This code is in a method invoked to create each video and is therefore executed before form.show(), so the UITimer runnable is invoked about half a second after the form is shown.
/*
* Workaround for the issue: https://stackoverflow.com/q/66144759
* "video" is a Media instance returned by MediaManager.createMedia
* This workaround is for Android only and it assumes we don't use autoplay
*/
if (form != null && DeviceUtilities.isAndroidNative()) {
UITimer.timer(500, false, form, () -> {
CN.invokeAndBlock(() -> {
video.play();
video.setVolume(0);
while (!video.isPlaying()) {
/*
* When in a scrollable container there are many videos,
* play does not start immediately, but only when the
* video becomes visible, so we must wait.
*/
Util.sleep(100);
}
Util.sleep(100); // extra wait to be sure that the waiting is not zero
video.pause();
video.setVolume(100);
});
form.addShowListener(l -> {
CN.invokeAndBlock(() -> {
video.play();
video.setVolume(0);
while (!video.isPlaying()) {
// same as above
Util.sleep(100);
}
Util.sleep(100); // as above
video.pause();
video.setVolume(100);
});
});
});
}
Hi I am trying to integrate Cocos3D into my current project.
I can successfully run it when i set UIViewControllerCOCOS containing Cocos3D code (Listed below) in App Delegate as root of UINavigationController.
But if i use some other viewController say OtherVC and push UIViewControllerCOCOS on navigationController then it crashes on
_viewController.supportedInterfaceOrientations = UIInterfaceOrientationMaskAll; //APPLICATION CRASH HERE SAYING -[CCDirectorDisplayLink setSupportedInterfaceOrientations:]: unrecognized selector sent to instance 0x146ab0b0. Where
_viewController is CC3DeviceCameraOverlayUIViewController* _viewController;
I have used Cocos3D hello world code.
//UIViewControllerCOCOS.m
-(void) viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
[self setupCocos3D];
}
-(void)setupCocos3D{
CCTexture2D.defaultAlphaPixelFormat = kCCTexture2DPixelFormat_RGBA8888;
// Establish the view controller and CCDirector (in cocos2d 2.x, these are one and the same)
[self establishDirectorController];
[self.view addSubview:_viewController.view];
// ******** START OF COCOS3D SETUP CODE... ********
// Create the customized CC3Layer that supports 3D rendering.
cc3Layer = [Nabru_cocos3dLayer layerWithController: _viewController];
// Create the customized 3D scene and attach it to the layer.
// Could also just create this inside the customer layer.
cc3Layer.cc3Scene = [Nabru_cocos3dScene scene];
// Assign to a generic variable so we can uncomment options below to play with the capabilities
CC3ControllableLayer* mainLayer = cc3Layer;
_viewController.controlledNode = mainLayer;
// Run the layer in the director
CCScene *scene = [CCScene node];
[scene addChild: mainLayer];
[CCDirector.sharedDirector runWithScene: scene];
}
-(void) establishDirectorController {
_viewController = CC3DeviceCameraOverlayUIViewController.sharedDirector;
_viewController.supportedInterfaceOrientations = UIInterfaceOrientationMaskAll; //APPLICATION CRASH HERE SAYING -[CCDirectorDisplayLink setSupportedInterfaceOrientations:]: unrecognized selector sent to instance 0x146ab0b0. If i comment out this line then it crash second line below it.
_viewController.viewShouldUseStencilBuffer = NO; // Set to YES if using shadow volumes
_viewController.viewPixelSamples = 1; // Set to 4 for antialiasing multisampling
_viewController.animationInterval = (1.0f / kAnimationFrameRate);
_viewController.displayStats = YES;
[_viewController enableRetinaDisplay: YES];
}
Any suggestion please?
I would like to rearrange UICollectionView cells during the rotation of my device in a similar way this is done in the evernote iPads app for the notes. In the default implementation there is just a fade-in and fade-out of the cells but i would like to have the cells to move around during the rotation.
What would be the recommended way to achieve a similar animation? Do I need to create a custom UICollectionViewLayout?
I managed to get the desired rotation effect by subclassing UICollectionViewFlowLayout and overriding the two methods: initialLayoutAttributesForAppearingItemAtIndexPath and finalLayoutAttributesForDisappearingItemAtIndexPath which are the two points of controls to respectively define the starting/final layout information for an item being inserted into the collection view.
See source code:
.h:
#import "UICollectionView.h"
#interface UITestCollectionViewFlowLayout : UICollectionViewFlowLayout
#end
.m:
#import "UITestCollectionViewFlowLayout.h"
#interface UITestCollectionViewFlowLayout ()
{
BOOL _isRotating;
}
#property (strong, nonatomic) NSIndexPath* lastDissappearingItemIndex;
#end
#implementation UITestCollectionViewFlowLayout
#synthesize lastDissappearingItemIndex = _lastDissappearingItemIndex;
// returns the starting layout information for an item being inserted into the collection view
- (UICollectionViewLayoutAttributes *)initialLayoutAttributesForAppearingItemAtIndexPath:(NSIndexPath *)itemIndexPath
{
UICollectionViewLayoutAttributes* attributes = (UICollectionViewLayoutAttributes *)[self layoutAttributesForItemAtIndexPath:itemIndexPath];
if (_isRotating) // we want to customize the cells layout only during the rotation event
{
if ([self.lastDissappearingItemIndex isEqual:itemIndexPath])
return nil; // do not animate appearing cell for the one that just dissapear
else
{
attributes.alpha = 0;
// setting the alpha to the new cells that didn't match the ones dissapearing is not enough to not see them so we offset them
attributes.center = CGPointMake(attributes.center.x, attributes.size.height * 2 + attributes.center.y);
}
}
return attributes;
}
// returns the final layout information for an item that is about to be removed from the collection view
- (UICollectionViewLayoutAttributes *)finalLayoutAttributesForDisappearingItemAtIndexPath:(NSIndexPath*)itemIndexPath
{
UICollectionViewLayoutAttributes* attributes = (UICollectionViewLayoutAttributes *)[self layoutAttributesForItemAtIndexPath:itemIndexPath];
if (_isRotating)
{
attributes.alpha = 1.0;
self.lastDissappearingItemIndex = itemIndexPath;
}
return attributes;
}
- (void) viewController:(UIViewController *)viewController didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
_isRotating = NO;
}
- (void) viewController:(UIViewController *)viewController willRotateToInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation duration:(NSTimeInterval)duration
{
_isRotating = YES;
}
Note that i am using a flag that i set from the viewcontroller who create this flowlayout to know when we are actually rotating or not; the reason being that i want this effect to happen only during rotation.
I am interested to hear feedbacks/improvement about this code.
I have a UIImageView embedded inside a UIScrollView, prior to iOS 6 and autolayout I used the following snippet inside the controller's viedDidLoad method to display a scrollable and zoomable image.
self.scrollView.contentSize = self.imageView.image.size;
self.imageView.frame = CGRectMake(0, 0, self.imageView.image.size.width, self.imageView.image.size.height);
But now the constraints set in the storyboard are used instead. I've found this question Embed ImageView in ScrollView with Auto Layout on iOS 6 and some others here in SO stating that constraints are loaded/enforced after viewDidLoad, and that moving my previous snippet to viewDidAppear would fix this issue but zooming does not work properly and it seems that the sizes of the scrollView and the imageView are reset to the storyboard's constraint after a pinch-to-zoom gesture.
I'm just guessing, but I think maybe if there's some way to override the scrollView's and imageView's vertical and horizontal space constraints in code that might work.
Anyone else having this issues?
The best solution was proposed by Zsolt in the comments:
http://github.com/evgenyneu/ios-imagescroll check this out. Works perfectly for me.
The solution proposed in this repository is to adjust the minimum and current zoom level before displaying the image:
#interface MyViewController () <UIScrollViewDelegate>
#property (weak, nonatomic) IBOutlet UIScrollView *scrollView;
#property (weak, nonatomic) IBOutlet UIImageView *imageView;
#end
#implementation MyViewController
- (void)viewDidLoad
{
[super viewDidLoad];
self.scrollView.delegate = self;
[self initZoom];
}
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
[self initZoom];
}
// Zoom to show as much image as possible
- (void) initZoom {
float minZoom = MIN(self.view.bounds.size.width / self.imageView.image.size.width,
self.view.bounds.size.height / self.imageView.image.size.height);
if (minZoom > 1) return;
self.scrollView.minimumZoomScale = minZoom;
self.scrollView.zoomScale = minZoom;
}
- (UIView*)viewForZoomingInScrollView:(UIScrollView *)scrollView
{
return self.imageView;
}
However sample conatins issue with zooming out. Image is not getting centered. This can be easily fixed by using the custom scroll view class with the following code in it:
#interface MyScrollView : UIScrollView
#end
#implementation MyScrollView
-(void)layoutSubviews
{
[super layoutSubviews];
UIView* v = [self.delegate viewForZoomingInScrollView:self];
CGFloat svw = self.bounds.size.width;
CGFloat svh = self.bounds.size.height;
CGFloat vw = v.frame.size.width;
CGFloat vh = v.frame.size.height;
CGRect f = v.frame;
if (vw < svw)
f.origin.x = (svw - vw) / 2.0;
else
f.origin.x = 0;
if (vh < svh)
f.origin.y = (svh - vh) / 2.0;
else
f.origin.y = 0;
v.frame = f;
}
#end
Solved my problem using the following code sample. The github repository corresponds to the book Programming iOS by Matt Neuburg.
https://github.com/mattneub/Programming-iOS-Book-Examples/blob/11c6c57743b04e6e722b635b87be69fa41a5abaf/ch20p573scrollViewAutoLayout/ch20p573scrollViewAutoLayout/ViewController.m
I also agree with Zsolt's suggestion and link.
But I update the width/height constraints to allow it to handle any size image:
- (void) initZoom
{
for (NSLayoutConstraint *constraint in self.photoImageView.constraints)
{
if (constraint.firstAttribute == NSLayoutAttributeWidth)
constraint.constant = self.photoImageView.image.size.width;
else if (constraint.firstAttribute == NSLayoutAttributeHeight)
constraint.constant = self.photoImageView.image.size.height;
}
float minZoom = MIN(self.scrollView.bounds.size.width / self.photoImageView.image.size.width,
self.scrollView.bounds.size.height / self.photoImageView.image.size.height);
if (minZoom > 1) return;
self.scrollView.minimumZoomScale = minZoom;
self.scrollView.zoomScale = minZoom;
}
I have just updated to IOS 6 and now when I run my app the MPMoviePlayerControler shows the video incorrectly. The app is landscape but when the video is displayed in portrait. I have created new .h and .m files which is a child of MPMoviePlayerController. Here are my two files
.h
#import <Foundation/Foundation.h>
#import "cocos2d.h"
#import <MediaPlayer/MediaPlayer.h>
#interface TrashPackPlayer : MPMoviePlayerController
#end
.m
#import "TrashPackPlayer.h"
#implementation TrashPackPlayer
-(id)init{
[super init];
return self;
}
- (BOOL)shouldAutorotate
{
return YES;
}
- (NSInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
return UIInterfaceOrientationIsLandscape(toInterfaceOrientation);
}
#end
I create the media player like this:
player = [[TrashPackPlayer alloc] initWithContentURL:videoURL];
player.view.frame = CGRectMake(0, 0, sharedInfo.screenSize.width, sharedInfo.screenSize.height);
player.controlStyle = MPMovieControlStyleFullscreen;
player.scalingMode = MPMovieScalingModeAspectFit;
[player play];
[[[CCDirector sharedDirector] openGLView] addSubview:player.view];
Is this correct?
What do I need to do to get this displaying correctly?
Rotations in iOS6 have changed dramatically, check the fourth point at:
http://megawertz.com/blog/2012/9/20/ios-6-and-rotation
The top-most view controller is in charge of setting the allowed orientations, subclassing a view controller is not going to solve your problem.
