Hi Guys This is not an uiview orientation question, I want to Have the iphone in Portrait or Landscape, and I want a standard tableview(controller?) that will display cells in a vertical strip down the iphone and the tableview scrolls horizontally. -I.e. a 100% normal tableview, that is rotated 90deg without rotating the phone orientatio...
I am wondering what is the best way to implement rotation-based dragging movements in my iPhone application. I have a UIView that I wish to rotate around its centre, when the users finger is touch the view and they move it. Think of it like a dial that needs to be adjusted with the finger. The basic question comes down to: 1) Should ...
Hi, for rotation of my app I use the same view and just rearrange some controls resp. define the appropriate autosize attributes. So, for example, I have a segmented control which goes from the left to the right over the complete screen. When rotating it resizes correct, but I get no events from the segments on the right side (I guess, ...
I have two UIViewControllers, "A" and "B", where "A" overrides the shouldAutorotateToInterfaceOrientation to return YES for UIInterfaceOrientationPortrait, and "B" returns YES for all orientations. In my example "A" is the root navigation view controller, and I then use pushViewController for "B". After that I rotate the device into land...
I need to rotate a 2d sprite about the y axis. E.g., I have a 2d top-view sprite of an aircraft. When the user turns the aircraft the wings should tilt into (or out of) the screen to show that it is turning. Is there a way to put the image into java3d, rotate it, and then put it back into a buffered image? Or maybe somehow knows how t...
I would like apply a 3D rotation on a view (in particular to a UILabel) in iPhone. What's the simplest way to do this? A code example will be much appreciated. ...
Hi, I use a UITabBarController with 4 views. The first of those 4 views should be able to rotate, the other three not. And now the problem is, when having a tab bar controller you have to set all used views to rotatable (i.e. returning TRUE in shouldAutorotateToInterfaceOrientation). So, my question is now, can I prevent the three vie...
I am using CAKeyFrameAnimation to do rotation of an arrow image. Problem is that the imageview is returning back to the previos state after animation. Code: CAKeyframeAnimation *rotation = [CAKeyframeAnimation animation]; rotation.duration = 0.55; rotation.cumulative = TRUE; rotation.removedOnCompletion = NO; if (isFlipRight) ...
I've created a custom UIViewController that mimics the UISplitViewController. It manages two child view controllers that get displayed in the left & right body area while in landscape and hides the left to show in a popover when in portrait. It works fine, using the didRotateFromInterfaceOrientation: and willRotateToInterfaceOrientation:...
I'm trying to setup log rotation in rails. I have put this in my environment/development.rb: config.logger = Logger.new("#{RAILS_ROOT}/log/#{ENV['RAILS_ENV']}.log", 1, 5*1048576) 2 files are created :-) but it looks like rails is writing to them randomly and at the same time as well. This creates messy log files :-( what am I missing? ...
I have two vectors describing rotations; a start rotation A and a target rotation B. How would I best go about interpolating A by a factor F to approach B? Using a simple lerp on the vectors fails to work when more than one dimension needs to be interpolated (i.e. produces undesirable rotations). Maybe building quaternions from the rota...
I have written a TestSuite to find out how to calculate the rotation angles from the data you get in SensorEventListener.onSensorChanged(). I really hope you can complete my solution to help people who will have the same problems like me. Here is the code, i think you will understand it after reading it. Feel free to change it, the main...
I use slerp to interpolate between two quaternions representing rotations. The resulting rotation is then extracted as Euler angles to be fed into a graphics lib. This kind of works, but I have the following problem; when rotating around two (one works just fine) axes in the direction of the green arrow as shown in the left frame here ...
Currently the setanchor function only sets the anchor within the sprite frame. Is there any (easier) wway to change the anchor point to a coordinate on screen space? My purpose is to allow the sprite to rotate around a circle. TIA for any suggestions made. ...
Hi, I'm having real trouble finding out how to rotate an object arround two axes without changing axes orientation. I need only local rotation, first arround X axis and then arround Y axis(only example, it doesn't matter how many transformations arround which axes) without transforming the whole coordinate system, only the object. The p...
Hi, i have some CALayers one on top of the other with different z-values. the z-values are sequential (1,2,3 ...). i wrote some code that changes the y-rotation of a CALayer when i click on it. the y-rotations changes to -30.f the problem is that when i click on a CALayer it rotates and goes behind the CALayers that are actually beneat...
Hi, I'm trying to rotate a button that I've connected to the controller from the Interface Builder. I've set it's image right from Interface Builder. I'm using this code on the method that runs when I click it: [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:2.0]; [UIView setAnimationRepeatCount:5]; updateButton...
I have defined an object in 3D space with position, rotation and scale values (all defined as 3D vectors). It also has upwards and forwards direction vectors. When I rotate the object, I need these direction vectors to rotate with it. Assuming my up vector is (0, 1, 0) and my forwards vector is (0, 0, 1) at zero rotation, how might I ac...
Hello, I'm trying to present some UIModalFormSheets in a my iPad application. It's working without any problems, except one thing: When I have my iPad in landscape mode my modal form sheet is moving to the center of the screen and THEN rotates into the appropiate angle. All I want is to present the modal form sheet in the right angle a...
Is it possible to turn off the animation for the autorotation? I want it to rotate, but I just dont want the animation to occur (like an instant switch). ...
