objective-c - 如何旋轉(zhuǎn)嵌入UIWebView的視頻(iOS 7)?
問題描述
我在開發(fā)的APP是面向肖像的,但是當(dāng)運(yùn)行視頻(內(nèi)嵌在webview)的時候,我需要在風(fēng)景模式下重新定位視頻。應(yīng)該怎么解決這一問題呢?我找到了一種解決方案,似乎可以解決問題。我覺得這是因為iOS 7的更新,但是我不確定。所以,這是我先前使用的,但是現(xiàn)在不起作用了,因為窗口和類名總是nil。
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{id presentedViewController = [window.rootViewController presentedViewController];NSString *className = presentedViewController ? NSStringFromClass([presentedViewController class]) : nil;if (window && [className isEqualToString:@'MPInlineVideoFullscreenViewController']) { return UIInterfaceOrientationMaskAll;} else { return UIInterfaceOrientationMaskPortrait;}

問題解答
回答1:答案:Denisia我自己找到了解決方法!在AppDelegate中執(zhí)行如下方法,成功了!我的問題是,開始的時候,我沒有檢查右視圖控制器(view controller)。
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {NSString *className = NSStringFromClass([window class]);if ([((UINavigationController *)window.rootViewController) respondsToSelector:@selector(visibleViewController)]) { className = NSStringFromClass([((UINavigationController *)window.rootViewController).visibleViewController class]);}if ([className isEqualToString:@'MPFullscreenWindow'] || [className isEqualToString:@'MPInlineVideoFullscreenViewController']) { return UIInterfaceOrientationMaskAll;} else if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad){ return UIInterfaceOrientationMaskLandscape;} else { return UIInterfaceOrientationMaskPortrait;}
Immi試試這個:
-(BOOL)shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation{return YES;}
如果你想在屏幕不顯示視頻的時候,不讓UIViewController旋轉(zhuǎn),就使用下面的:
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{if(webView && webView.superView) return YES;return UIInterfaceOrientationIsPortrait(interfaceOrientation);}
