問(wèn)題描述

我在開(kāi)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(shí)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(wèn)題呢？我找到了一種解決方案，似乎可以解決問(wèn)題。我覺(jué)得這是因?yàn)閕OS 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?yàn)榇翱诤皖?lèi)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;}

原問(wèn)題：How to rotate a video embed in UIWebView (for iOS 7 only)?

問(wèn)題解答

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(wèn)題是，開(kāi)始的時(shí)候，我沒(méi)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(gè)：

-(BOOL)shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation{return YES;}

如果你想在屏幕不顯示視頻的時(shí)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);}
