orientation

问题 Which is the best way to change the UI when orientation is changed? For example, use two different UIView one portrait and a landscape and show one of both if orientation is changed, or use one UIView and change the UI control sizes and positions? Any other ideas? 回答1: - (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration { if (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft || toInterfaceOrientation ==

问题 After reading many posts, I still haven't got a clue how to solve this problem... The first view of my app is a tableViewController. I override (BOOL) shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation and it always returns YES. If I hold my iPad upright under landscape orientation, it rotates right after I launch the app. However, if I put my iPad flat on the table, even though my homepage is in landscape orientation, it launches in protrait orientation. So

问题 I've been trying to figure this out for a while now and its possibly a duplicate but I haven't found a correct solution. So I've created a view controller and the build the xib in landscape mode. When I try to push the view controller, it displays as Portrait but I want it to show up landscape. I've added the following methods to my code: - (BOOL)shouldAutorotate { return YES; } -(NSUInteger)supportedInterfaceOrientations { return UIInterfaceOrientationMaskLandscapeRight |

问题 To get this, I've made three kind of modify in android system(v4.04).They are: 1. WindowsManagerService.java, modified the getOrientationFromWindowsLocked(); 2. Activity.java, modified the onResume(); 3. PhoneWindowManager.java, modified the setInitialDisplaySize(); They all get work, but also with some side effect. So is there a better modify for this? Any suggestion will greatly appreciated. Thanks very much. 回答1: According to me you have to modified your SensorManager class in android. The

问题 First of all, I would like to apologize for asking the same question again which has been asked in this forum many times. But, my problem is that I've tried all the suggested solutions but still I haven't got a solution to my problem. I have a ViewControllerA in Potrait mode and ViewControllerB in landscape mode. When the device changes from potrait to landscape, i can see ViewControllerB opening in landscape mode, but when the device is rotated back to potrait mode, ViewControllerA is

问题 I have a UIViewController with a UIView subclass as a subview, and in here is a UITableView added as a subview of that UIView, as follows: UIViewController -UIView --UITableView (plucked from a UITableViewController) On an iPad, if I load the view controller in either orientation I can interact with the table view perfectly. However, if I rotate the device to a new orientation - I have code that alters the frames to make it fit the new resolution, but a small area of the table does not

问题 I would need a child layout (can be any layout, like FrameLayout or RelativeLayout ) to ignore orientation change and remain always in landscape orientation. But not its parent or any other sibling layouts/views, they should change their orientation accordingly. Hence, I cannot use setRequestedOrientation() or android:screenOrientation="landscape" . Or it will lock the orientation for the whole screen or the activity. I need to lock only just this single layout. My layout XML: RelativeLayout

Maybe i can write it to EXIF data ? Thx for help. EDIT: Thx to Jonathan Cichon, now i got a image orientation with

问题 I know this question was already asked in here, here and here. I tried all possible ways but wasn't successful. I'm trying to develop an application in Swift (iOS 8), in which only one view controller can be viewed in all orientations others in only portrait. For this, I have enabled only Portrait mode in Target->General->Device Orientation (because I want the application to operate only in portrait mode except one view controller). I have added below code to the view controller that I want
