preferredInterfaceOrientationForP
全部标签 我正在使用iOS8的UIPresentationController编写自定义模式演示文稿。呈现的Controller具有首选界面方向UIInterfaceOrientationLandscapeLeft。在使用UIPresentationController呈现此Controller时,它以纵向显示,忽略呈现的Controller的preferredInterfaceOrientationForPresentation方法的结果。呈现ViewControlleroverridefuncprepareForSegue(segue:UIStoryboardSegue,sender:Any
我有2个UIView。第一个仅支持纵向。第二个肖像和风景。为实现这一点,我更改了supportedInterfaceOrientations的返回值,以便它根据我的View给出正确的方向。当我从屏幕2切换到屏幕1时,View仍然处于有问题的横向形式,但是当我旋转设备时,View实际上旋转为纵向并正确锁定在那里。原因是当我旋转设备时,将触发旋转更改事件。我的问题:有没有办法以编程方式触发方向更改事件? 最佳答案 我相信您正在寻找的是View1上的preferredInterfaceOrientationForPresentation:
我的应用程序窗口的RootViewController是UINavigationController的子类。我已将此代码添加到类(class)中:-(BOOL)shouldAutorotate{return[self.topViewControllershouldAutorotate];}-(NSUInteger)supportedInterfaceOrientations{return[self.topViewControllersupportedInterfaceOrientations];}-(UIInterfaceOrientation)preferredInterfaceOr
此错误没有意义,因为首选方向UIInterfaceOrientationLandscapeRight由支持的方向返回//iOS6-(BOOL)shouldAutorotate{returnNO;}-(NSUInteger)supportedInterfaceOrientations{return(UIInterfaceOrientationLandscapeRight|UIInterfaceOrientationLandscapeLeft);}-(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{re
此错误没有意义,因为首选方向UIInterfaceOrientationLandscapeRight由支持的方向返回//iOS6-(BOOL)shouldAutorotate{returnNO;}-(NSUInteger)supportedInterfaceOrientations{return(UIInterfaceOrientationLandscapeRight|UIInterfaceOrientationLandscapeLeft);}-(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{re
我正在使用MSNavigationPaneViewControllerfromhere并进行轮换工作。我已经覆盖了根UINavigationController中的旋转方法-(BOOL)shouldAutorotate{returnYES;}-(NSUInteger)supportedInterfaceOrientations{AppDelegate*appDelegate=(AppDelegate*)[[UIApplicationsharedApplication]delegate];if(appDelegate.topViewController!=nil){return[appD
