autorotate

问题 I'm having a problem handling rotation in a view controller. When the view is topmost and the phone is rotated, it adapts correctly. When there's a view controller being presented modally over it and the device is rotated, the view controller under is not fully updated for the rotation when the user returns. The biggest problem I appear to be having is that the separator lines don't expand to fill the whole width. Example: I've uploaded my test project to GitHub; you can clone it from https:/

问题 I've got an app where I have a UINavigationController subclass as my rootViewController . I've got a UITableViewController that lets the user edit some settings, it should always be in portrait mode. My app also needs to support all other orientations after I push a MoviePlayer component onto the navigation controller. The UITableViewController subclass has this implementation of supportedInterfaceOrientations: - (NSUInteger)supportedInterfaceOrientations { LLog(); return

问题 My iPad app makes heavy use of autorotation. This is great. However, I've noticed that if a hidden view is released by the default implementation of didReceiveMemoryWarning (as described here), when the view is re-loaded from the nib and I happen to be in landscape, it loads it in portrait. This wreaks havoc with the interface until I rotate the iPad manually and force it to go to the proper orientation. I had assumed that iOS would load the view in the current orientation; that's what it

问题 How can I rotate a rectangle infinitely - ONLY within xaml definition. So far I found a solution with code but no xaml: http://www.codeproject.com/Articles/23257/Beginner-s-WPF-Animation-Tutorial which I use like this: private void Window_Loaded_1(object sender, RoutedEventArgs e) { var doubleAnimation = new DoubleAnimation(360, 0, new Duration(TimeSpan.FromSeconds(1))); var rotateTransform = new RotateTransform(); rect1.RenderTransform = rotateTransform; rect1.RenderTransformOrigin = new

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 4 years ago . Updated my question I'm building a crawler system by Java to compare price online. However, I worry about my IP address can be banned. So I intend to use proxy to change IP dynamic or use some tools to rotate IP automatically. Many people said that TOR is a powerful tool to rotate

问题 I've got a view controller listening for both UIKeyboardWillShowNotification and UIKeyboardWillHideNotification. The handlers for these notifications adjust various parts of the view, which is standard procedure. The following code is used to convert the keyboard rect from screen coordinates: CGRect keyboardBounds = [self.view convertRect:[keyboardBoundsValue CGRectValue] fromView:nil]; Again, standard procedure. Unfortunately, there is a critical situation where this conversion fails. Look

问题 I can't keep popover the same position on the screen after rotation. Is there any good way to do that, because just setting some frame to popover works terrible after rotating. popover.frame = CGRectMake(someFrame); After rotation popover looks fine only if it is in the center of the screen. 回答1: Apple has a Q&A on exactly this issue. You can find the details here: Technical Q&A QA1694 Handling Popover Controllers During Orientation Changes Basically, the technique explains that in your view

问题 What else should I do? -(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation) toInterfaceOrientation { return (toInterfaceOrientation == UIInterfaceOrientationPortrait); } - (NSUInteger)supportedInterfaceOrientations { return UIInterfaceOrientationMaskPortrait; } -(BOOL)shouldAutoRotate { return NO; } My viewController still rotates. It is embedded in a navigation stack. If I subclass UINavigationController, and implement the same portrait-only templates there, and I embed my

问题 My app can autorotate but I need one of the views to only show in portrait mode and don't know how to achieve this. I tried this (among other things) but the view in question still rotates: // ViewController.m -(BOOL)shouldAutorotate { return NO; } - (NSUInteger)supportedInterfaceOrientations { return UIInterfaceOrientationMaskPortrait; } Can someone kindly point out what I'm doing wrong? Thanks. -edit- It's for iOS 6.1 回答1: When a UINavigationController is involved, create a category on the

问题 I'm trying to prevent rotation on one UIViewController and I can't achieve that. I'm doing something like this: open override var shouldAutorotate: Bool { get { return false } } override var supportedInterfaceOrientations: UIInterfaceOrientationMask { get { return .portrait } } And the UIViewControler stills rotating. The UIViewController is inside a UINavigationController opened modally. I have looked a lot of questions from here and none answers works for me. In Swift 2 I used to override
