I use a tabBar Controller as root controller. It has 4 tabs and each of its ViewControllers has - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation { return YES; } as long as the tabBarController itself. But when I rotate the device (real or simulator), the screen turns at random! If i...
Hi, I'm using a class which applies a visual reflection-effect to defined movieclips. I use a reflection-class from here: link to source. It works like a charm except when I apply a rotation to the movieclip. In my case the reflection is still visible but only a part of it. What am I doing wrong? How could I pass/include the rotation to ...

I am working on a drawing app. Right now, when the device is turned, all UI elements turn with it. What I am trying to do is have all the buttons, menus, etc. turn, but have my canvas U...
I have PhotoTest1Controller very similiar to the one in Three20 samples. I implemented necessary shouldRotate methods in necessary places in UITabBarController and UINavController derived classes as well as the table that contains PhotoTest1Controller. A funny thing is happening, when in thumbnail mode, the view rotates properly, but wh...
This is unfortunately a quite complex issue to explain, so please don't get discouraged by the wall of text - it's there for a reason. ;) I'm working on a transformation manager for flash, written with Actionscript 3. Users can place objects on the screen, for example a rectangle. This rectangle can then be selected and transformed: mo...
I have a custom UIViewController, which is the only subView of UIView. The UIViewController contains delegate function: (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } This function is called once when the application starts and is never called again when the device is rotated...
this may sound funny, but i spent hours trying to recreate a knob with a realistic rotation using UIView and some trig. I achieved the goal, but now i can not figure out how to know if the knob is rotating left or right. The most pertinent part of the math is here: - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { ...
I have a custom UITableViewCell which contains several UIButtons. Each button's frame position is relative to the cell width. I set autoresizingMask=UIViewAutoresizingFlexibleWidth so it will adjust the cell width and the button positions properly when the application starts with the device either in landscape or portrait mode. The iss...

I'm trying to work out a problem I'm having with degrees. I have data that is a list of of angles, in standard degree notation -- e.g. 26 deg. Usually when dealing with angles, if an angle exceeds 360 deg then the angle continues around and effectively "resets" -- i.e. the angle "starts again", e.g. 357 deg, 358 deg, 359 deg, 0 deg, 1 ...
Hi. How do I rotate the ImageView ... i'm trying to use landscape mode, and have a problem with accelerometer moving the image ... Because when I work in portrait mode the x of accelerometer is the same as the x of the image ... But when I work landscape, the x of accelerometer is the y of the image, because the ImageView autorotates wi...
Hi, I had a look around and didn't find what I was exactly looking for ... Is there a way to get a flip animation when pushing a view controller ? I read that you can change the animation by using a modal view controller but AFAIK the animation for a modal view is from bottom to top and that's not what i am looking for ;) Is there a ...
I am currently working on a simple Silverlight app that will allow people to upload an image, crop, resize and rotate it and then load it via a webservice to a CMS. Cropping and resizing is done, however rotation is causing some problems. The image gets cropped and is off centre after the rotation. WriteableBitmap wb = new WriteableBit...
I have come across some very unexpected (and incredibly frustrating) functionality while trying to restore the state of a list of CheckBoxes after a screen rotation. I figured I first would try to give a textual explanation without the code, in case someone is able to determine a solution without all the gory details. If anyone needs m...
Edited Mar 30 - Note: Monotouch used. When I rotate to LandscapeRight/Left I want to change the location of some of my buttons. Here's what I'm trying: Have my ShouldAutorotateToInterfaceOrientation returning True. In my WillRotate (I tried putting this in DidRotate as well) it doesn't show any difference, here's my code: public ...
I have this chronic issue with iPhone UI development where views sometimes seem to appear on the screen in a location different than what is reported by their frame property. Here is what I am doing to try to debug the issue: UIView *currentView = self.view; while (currentView!=nil) { NSLog(@"frame: %f,%f,%f,%f", currentView.frame.o...
