file uri scheme

So, I am fairly new to iOS programming, and have inherited a project from a former coworker. We are building an app that contains a gauge UI. When data comes in, we want to smoothly rotate our layer (which is a needle image) from the current angle to a new target angle. Here is what we have, which worked well with slow data: -(void) MoveNeedleToAngle:(float) target { static float old_Value = 0.0; CABasicAnimation *rotateCurrentPressureTick = [CABasicAnimation animationWithKeyPath:@transform.rotation); [rotateCurrentPressureTick setDelegate:self]; rotateCurrentPressureTick.fromValue = [NSSNumber numberWithFloat:old_value/57.2958]; rotateCurrentPressureTick.removedOnCompletion=NO; rotateCurrentPressureTick.fillMode=kCAFillModeForwards; rotateCurrentPressureTick.toValue=[NSSNumber numberWithFloat:target/57.2958]; rotateCurrentPressureTick.duration=3; // constant 3 second sweep [imageView_Needle.layer addAnimation:rotateCurrentPressureTick forKey:@rotateTick]; old_Value = target; }The problem is we have a new dat

Just wondering if (and if so, how) it's possible to archive my OS X app with the Address Sanitizer enabled (to give it to internal testers).The scheme editor in Xcode 7 makes it seem like that would not be possible, but maybe I'm missing something.

Dear all,I'm hoping someone will be able to advise me on how to resolve this error. I have tried numerous times to open files exported from Blender 2.74 in .obj, .stl or .ply formats, but get the same error message each time: 'The document testCube.obj could not be opened. Unknown or missing file'.Below is a description of how I generate the error, starting with the default cube object in Blender 2.74 and ending with Xcode7 beta:Open Blender. The 3D viewport contains the default cube object.In the Properties Window, click on the Materials buttonIn the Diffuse panel, set the colors to Red: 0.5, Green: 1.0, Blue: 1.0Save the file as 'testCube' to a folder on my desktopSelect File > Export > Wavefront(.obj)In the resulting Export window, click 'Export OBJ' without making any adjustments to the default settings in the 'Export OBJ' panel on the left hand side.Two files are saved to my folder: testCube.obj and testCube.mtlFirst approach to opening the file

So I've started to build my super game using SpriteKit. And there is one problem I can resolve with two different ways.When creating a sprite it is needed to point .png-file (SKSpriteNode(imageNamed: hero))..PNG file can be in .xcassets folder and have several versions (@2x, @3x) for each device (4s, 5, 6, 6+). But there is a way to use just one .png file and set correct scale property for a sprite.Is it a good practice to use one image and set scale or it is better to use concrete file (@2x or @3x) for a cpecific device?Pros using one file – smaller app size.

Hello,I changed a project from Objective-C to Swift and created a whole new project when I did this. I have an app in the AppStore and wanted to send an update instead of releasing a new app. I understand that my Bundle Identifier needs to be the same when updating an app. When preparing the app for release, I changed my Bundle Identifier to match my app in the AppStore - since I started with a new project - and in the process my Core Data file seems to be missing. If I change my Bundle Identifier how do I keep access to Core Data?Take care,Jon

Has anyone else been seeing really slow copy operations with the first beta? I just downloaded the Xcode 7 beta and have noticed that copying it and other files can take a very long time. It spends a very long time on preparing to copy before it actually starts the copy operation.

I'm using JXA to build Cocoa applications and running into a strange issue when attempting to wrap all an app's JavaScript with an immediately-invoked function expression.What's the issue?If the code for an app with a single NSWindow is wrapped in an immediately-invoked function, the app's window will close on it's own without any type of application crash. The app stays running.Here's the code I'm using:(function() { ObjC.import(Cocoa); var styleMask = $.NSTitledWindowMask | $.NSClosableWindowMask | $.NSResizableWindowMask | $.NSMiniaturizableWindowMask; var window = $.NSWindow.alloc.initWithContentRectStyleMaskBackingDefer( $.NSMakeRect(0, 0, 800, 400), styleMask, $.NSBackingStoreBuffered, false ); window.center; window.title = 'NSWindow Closure Bug?'; window.makeKeyAndOrderFront(window); }());Here's the example application https://dl.dropboxusercontent.com/u/271215/jsclosurebugexample.zipor recreate it with- Script Editor > New- Copy/paste the above code- Save > File Format: Applicat

Hi there, I'm still new to the development world.I want to ask you guys about how I could store data -like audio files or PDFs- inside the app -universal app- with objective-c ?? so the user can view, play, add to favorite or search them. without editting or deleting any of them.please help me & thanks in advanced .. 🙂
