I'm using below code.
self.picker=[[UIImagePickerController alloc] init];
self.picker.delegate=self;
self.picker.allowsEditing=NO;
self.picker.sourceType=UIImagePickerControllerSourceTypeCamera;
self.picker.cameraOverlayView=[self addCameraRollButton];
[self presentViewController:self.picker animated:NO completion:NULL];
How to take picture from camera without going to Usephoto page. I want to stay on camera view. I'm not able to get camera spinner action.I used custom overlay but in that Square focus not coming.Please help me.I want all default camera features.
Once you use custom overlay you will not be able to see default camera features.If you want all default features you should use
self.picker.showsCameraControls = YES;
This opens default camera and you can see all features.
If you want to go with custom overlay then you need to built all features.
Question:
Are there ways to animate anything within the LaunchScreen.xib file of an Xcode 6 Project targeted to deploy for iOS 8.1+ ?
Context:
I'm looking to make simple animations to convey activity or serve as a distraction to the user while they wait...
Examples:
A Loading Bar
Activity Indicator
Animated GIF
Move a UIImage across the Screen
Rotate an Image
Nope.
The Launch Image is shown only during the time period between when the user chooses to launch your app and when your app has actually started running. During this period, your app can't take any actions such as performing an animation — it's not running yet. The Launch Image is just a static image that, when well designed, helps give the user the impression that your app is ready quickly.
(Some developers ignore the HIG and use the launch image to provide a splash screen, sometimes with an animated presentation. But in those cases, the launch screen is still a static image, and the animation happens once the app begins running — it's just that the first frame of animation drawn by the running app matches the appearance of the static launch image.)
This behavior didn't change with the LaunchScreen.xib feature in iOS 8 — it still appears only before your app is actually running, so it's still a static image. What the LaunchScreen.xib feature gets you is the ability to adaptively produce a launch image for many different device sizes and styles without having to separately design, render, and ship in your app bundle different images for each size/orientation/etc.
If your app isn't actually ready to use by the time it gains control, think about whether the "loading" tasks you're doing at that time really need to be done immediately, or if you can let the user start doing some things right away and do more setup work on a background thread or defer it until it's actually needed.
I don’t use splash screens often but when I do, I want them to open like a book.
In all truth, I’m not a big fan of splash screens and even Apple recommends using a default.png that shows the controls (with no text) of the application:
Display a launch image that closely resembles the first screen of the application. This practice decreases the perceived launch time of your application.
Avoid displaying an About window or a splash screen. In general, try to avoid providing any type of startup experience that prevents people from using your application immediately.
from HIG Guidelines
However, some people love them and one app in particular has a nice implementation splash screen — Path 2.0. When you open Path, you’re greeted with their logo on a red version of the Apple linen texture that animates open like a book (or journal as that’s what Path considers themselves to be).
You can get the source for this project here: https://github.com/jaysonlane/OpenBook
Before we begin, let me preface this with a disclaimer: I am very new to animations in Cocoa so bear with me. If you spot unnecessary or inefficient code, please leave a comment and I’ll tidy it up.
If you haven’t seen the animation, hop on the app store and pick up a copy to see what we’re trying to accomplish. I’ve created a default png that we can use cleverly titled Math (like a Math book that opens, right?) You can download that here (retina) and here.
To get started, let me explain “the trickery” behind what we’ll be doing: we’re going to use the normal default splash system in place to display our default.png. In the App Delegate, once the application has finished launching, we’re going to create a UIImageView on top of our view of that same default.png. We’ll then animate that UIImageView, to rotate open to reveal our view.
So let’s go:
Create a new project, I created one using the single view template but this will work with whatever. Go ahead and set your default.png and default#2x.png to the images supplied. You can do this by clicking the project in the navigation pane on the left, click the Target and scroll down to launch images:
Open your AppDelegate.m and add the following code to your application didFinishLaunching or application didFinishLaunchingWithOptions function:
//1. add the image to the front of the view...
UIImageView *splashImage = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
[splashImage setImage: [UIImage imageNamed:#"Default"]];
[self.window addSubview:splashImage];
[self.window bringSubviewToFront:splashImage];
//2. set an anchor point on the image view so it opens from the left
splashImage.layer.anchorPoint = CGPointMake(0, 0.5);
//reset the image view frame
splashImage.frame = CGRectMake(0, 0, 320, 480);
//3. animate the open
[UIView animateWithDuration:1.0
delay:0.6
options:(UIViewAnimationCurveEaseOut)
animations:^{
splashImage.layer.transform = CATransform3DRotate(CATransform3DIdentity, -M_PI_2, 0, 1, 0);
} completion:^(BOOL finished){
//remove that imageview from the view
[splashImage removeFromSuperview];
}];
Three things are happening here…
1) We create a new UIImageView and add it to the top of the view
2) We set an anchor point on the left side of the image to make it open from the left and then reset the frame to the full size of the view
3) We animate the UIImageView and remove it from the view on completion
That’s it, it’s that simple.

You can create the LaunchScreen.xib and then create a perfect replica that you can put code on and have a class like LaunchScreenAnimator that you can call form your delegate and that has a delegate to tell you when the animation is over
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
LaunchScreenAnimator *la=[LaunchScreenAnimator createWithDelegate:self];
self.window.rootViewController=la;
[self.window makeKeyAndVisible];
[la startAnimation];
return YES;
}
-(void) splashAnimationFinished:(LaunchScreenAnimator*)view
{
[self startWithDashboardWindow]; // replace the current rootViewController with whatever you want
}
I'm noticing in iOS8, when showing an UIImagePicker with a camera via modal, the edge of the screen is cut off.
Here is a sample image (notice the 'flip' icon is cut off on the edge):
Oddly enough, this behavior is on both iPhone 5 & iPhone 6.
I'm working with the standard UIImagePickerController in iOS
UIImagePickerController* picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = NO;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:nil];
This is inside of another UIViewController, which fits just fine on the screen. I've played with some of the settings, including 'extend edges', but nothing seems to change this slight cutoff.
Has anyone experienced this, or know of a fix?
UPDATE
I've narrowed the cause down to Pixate's Freestyle library. Disabling the library entirely removes the issue, but deleting all of the styles in my scss files does not fix it, so it must be something deeper in Pixate, rather than a style rule.
I am newbie to iOS programming.
I have a few simple questions.
After picking image from gallery or taking a picture from camera, I want to select
rectangle area like android
UIImagePickerController * picker =[[UIImagePickerController alloc] init];
picker.delegate=self;
picker.allowsEditing=YES;
picker.sourceType=UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:nil];
When I use this code, I can't resize my area as you see below
.
It is related to first question.
As you see my image is resized and changed to different ratio.
But I want image is fixed with original ratio.
Anyone knows how to use camera in iOS simulator?
Question 3: You cannot use the camera function in simulator. That is one of the limitations. See this document from Apple Developer page: https://developer.apple.com/library/ios/documentation/IDEs/Conceptual/iOS_Simulator_Guide/TestingontheiOSSimulator/TestingontheiOSSimulator.html
Question 2: below
This is answer is from this link: How to make UIImageView automatically resize to the size of the image loaded
UIImage img = [UIImage imageNamed:#"myImage.jpg"];
[imageView setImage:img];
imageView.frame = CGRectMake(imageView.frame.origin.x, imageView.frame.origin.y,
img.size.width, img.size.height);
"This will however not change the layout of view it is contained within, you can make it change the sizes of the other views automatically under iOS 6 using Layout Constraints. If you are an Apple Developer you can watch the WWDC instruction videos, they explain how that system works quite well."
It's the best answer I have as it is the way I use setting image sizes in a view.
I work on an app, which scans an image and shows you a 3D-Object or a video on top of the image target. Normal AR-App. For that AR stuff I usw the Vuforia SDK. The problem is, that the Vuforia SDK don't support animated 3D-Objects and for that I use cocos3d.
So I created a basic cocos3d app and included my vuforia stuff for the AR. This works good and the app displays normal 3D-Objects and videos. This was the background, now the problem.
The first view I have is my camera view, which scans the images. If I scan now a specified target, I want to show an animated 3D-Object. For that, I display the cocos3d view on top of the AR-View. The cocos3d view is transparent and is displayed on top of the AR-View (tested this with a simple button in the cocos3d view).
The problem is, that I'am not able to display a animated 3D-Object. I tested some options but none of them worked because I don't really have an idea how to do that. My current code:
CCDirector *director = CCDirector.sharedDirector;
EAGLViewCC *glView = [EAGLViewCC viewWithFrame:[window bounds] pixelFormat:kEAGLColorFormatRGBA8 depthFormat:GL_DEPTH_COMPONENT16_OES];
[director setOpenGLView:glView];
[window addSubview:director.openGLView];
After that I have a layer and add the test scene to my layer (Standard from the example). But than I don't know how to display it. It tried this:
[director pushScene:scene];
but no luck. In the example, they use this code to show the object (viewController is of type "CC3DeviceCameraOverlayUIViewController").
[viewController runSceneOnNode: mainLayer];
Why don't I use the viewController? Because I couldn't get the view transparent. So how do I get the 3D-Object displayed in my view? What do I have to do? Am I completely wrong?
