iOS16适配屏幕旋转横屏

iOS16之前转屏方法setOrientation:, 16之后使用无效.
固然Xcode14/iOS16提供了新的api但照旧beta版, 不能直接打包上线, 以是要在旧版适配新版本.
怎么适配实验了很多方法, 好比横屏时直接present一个横屏VC, 但耗时耗力, 怎么花最小代价适配iOS16, 看下面...
未升级Xcode14提前调试iOS16

下载iOS16体系支持包
放到这个件夹下, 重启Xcode就可以了
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
iOS16新增转屏api

UINavigationController *nav = [TYToolsUtil topViewController].navigationController; [nav setNeedsUpdateOfSupportedInterfaceOrientations]; NSArray *array = [[[UIApplication sharedApplication] connectedScenes] allObjects]; UIWindowScene *ws = (UIWindowScene *)array.firstObject; UIWindowSceneGeometryPreferencesIOS *geometryPreferences = [[UIWindowSceneGeometryPreferencesIOS alloc] init]; geometryPreferences.interfaceOrientations = UIInterfaceOrientationMaskLandscapeRight; [ws requestGeometryUpdateWithPreferences:geometryPreferences errorHandler:^(NSError * _Nonnull error) { NSLog(@"iOS 16 转屏Error: %@",error); }];但在升级xcode14之前不能直接调用到, 可以通过获取方法IMP调用
以是可以先这么适配, 上代码:
+ (void)setDevOri

UIDeviceOrientation)ori { @try { // ios16使用新的api if (@available(iOS 16.0, *)) { UIInterfaceOrientationMask oriMask = UIInterfaceOrientationMaskPortrait; if (ori == UIDeviceOrientationPortrait) { oriMask = UIInterfaceOrientationMaskPortrait; } else if (ori == UIDeviceOrientationLandscapeLeft) { oriMask = UIInterfaceOrientationMaskLandscapeRight; } else if (ori == UIDeviceOrientationLandscapeRight) { oriMask = UIInterfaceOrientationMaskLandscapeLeft; } else { return; } // 防止appDelegate supportedInterfaceOrientationsForWindow方法不调用 UINavigationController *nav = [TYToolsUtil topViewController].navigationController; SEL selUpdateSupportedMethod = NSSelectorFromString(@"setNeedsUpdateOfSupportedInterfaceOrientations"); if ([nav respondsToSelector:selUpdateSupportedMethod]) { (((void (*)(id, SEL))[nav methodForSelector:selUpdateSupportedMethod])(nav, selUpdateSupportedMethod)); } NSArray *array = [[[UIApplication sharedApplication] connectedScenes] allObjects]; UIWindowScene *ws = (UIWindowScene *)array.firstObject; Class GeometryPreferences = NSClassFromString(@"UIWindowSceneGeometryPreferencesIOS"); id geometryPreferences = [[GeometryPreferences alloc] init]; [geometryPreferences setValue

(oriMask) forKey

"interfaceOrientations"]; SEL selGeometryUpdateMethod = NSSelectorFromString(@"requestGeometryUpdateWithPreferences:errorHandler:"); void (^ErrorBlock)(NSError *error) = ^(NSError *error){ NSLog(@"iOS 16 转屏Error: %@",error); }; if ([ws respondsToSelector:selGeometryUpdateMethod]) { (((void (*)(id, SEL,id,id))[ws methodForSelector:selGeometryUpdateMethod])(ws, selGeometryUpdateMethod,geometryPreferences,ErrorBlock)); } } else { if ([[UIDevice currentDevice] respondsToSelector

selector(setOrientation

]) { SEL selector = NSSelectorFromString(@"setOrientation:"); if ([UIDevice currentDevice].orientation == ori) { NSInvocation *invocationUnknow = [NSInvocation invocationWithMethodSignature:[UIDevice instanceMethodSignatureForSelector:selector]]; [invocationUnknow setSelector:selector]; [invocationUnknow setTarget:[UIDevice currentDevice]]; UIDeviceOrientation unKnowVal = UIDeviceOrientationUnknown; [invocationUnknow setArgument:&unKnowVal atIndex:2]; [invocationUnknow invoke]; } NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:[UIDevice instanceMethodSignatureForSelector:selector]]; [invocation setSelector:selector]; [invocation setTarget:[UIDevice currentDevice]]; UIDeviceOrientation val = ori; [invocation setArgument:&val atIndex:2]; [invocation invoke]; } } } @catch (NSException *exception) { } @finally { }}留意: 使用iOS16方法, 调转屏方法后立即处理处罚UI, 大概造成界面繁芜.
