我的申请不是为了景观而设计的.但是,当我在UIWebView中打开我的YouTube频道并且用户启动视频时,它会显示在纵向.如果用户旋转他的iPhone,我想让它出现在横向模式.
如何在这种情况下启用景观模式? 我知道有这样做的“肮脏的黑客”,但我更喜欢更清洁的东西.此外,我不希望UIWebView切换到景观,只是视频可以. 解决方法
我终于调整了我的视图,以便它使用以下代码支持横向模式:
- (void)viewDidLoad { [super viewDidLoad]; [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(orientationChanged:) name:UIDeviceOrientationDidChangeNotification object:nil]; } - (void)viewWillAppear:(BOOL)animated { UIDeviceOrientation deviceOrientation = [UIDevice currentDevice].orientation; if (UIDeviceOrientationIsLandscape(deviceOrientation)) { //I set my new frame origin and size here for this orientation isShowingLandscapeView = YES; } else if (deviceOrientation == UIDeviceOrientationPortrait) { //I set my new frame origin and size here for this orientation isShowingLandscapeView = NO; } } - (void)orientationChanged:(NSNotification *)notification { // We must add a delay here,otherwise we'll swap in the new view // too quickly and we'll get an animation glitch [self performSelector:@selector(updateLandscapeView) withObject:nil afterDelay:0]; } - (void)updateLandscapeView { UIDeviceOrientation deviceOrientation = [UIDevice currentDevice].orientation; if (UIDeviceOrientationIsLandscape(deviceOrientation) && !isShowingLandscapeView) { //I set my new frame origin and size here for this orientation isShowingLandscapeView = YES; } else if (deviceOrientation == UIDeviceOrientationPortrait && isShowingLandscapeView) { //I set my new frame origin and size here for this orientation isShowingLandscapeView = NO; } } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return (interfaceOrientation == UIInterfaceOrientationPortrait || UIInterfaceOrientationIsLandscape(interfaceOrientation)); } (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
