苹果又给我们挖坑了,iOS 16屏幕旋转报错:[Orientation] BUG IN CLIENT OF UIKIT: Setting UIDevice.orientation is not supported. Please use UIWindowScene.requestGeometryUpdate(_:)
坑:听说xcode 14 和 xcode 13编译出的安装包效果不一,经测试确实如此!还是要打包测试完毕以后再上线哦!
经过实验,以前的方法直接给UIDevice setOrientation: 的方式还是生效的,只不过需要适配一下。
首先我们应该注意到iOS 16新增加了一个方法:setNeedsUpdateOfSupportedInterfaceOrientations
- /// Notifies the view controller that a change occurred that affects supported interface orientations or the preferred interface orientation for presentation.
- /// By default, this will animate any changes to orientation. To perform a non-animated update, call within `[UIView performWithoutAnimation:]`.
- - (void)setNeedsUpdateOfSupportedInterfaceOrientations API_AVAILABLE(ios(16.0));
这和更新状态栏的方法有点像,简单点说就是你想转屏可以,需要通知UIViewController 你已经准备好要转屏的方向了,然后再调用转屏方法即可(转屏方法后面会讲到)。
调用完转屏方法以后,view需要重新更新frame,这时候你会发现获取到的屏幕宽高并不是你要转屏以后的结果。难道是在iOS 16中转屏不及时更新UIScreen的size了? 可能是吧!这里我们就需要自己判断一下到底需要什么样的宽度和高度啦!
据我实验 - (BOOL)shouldAutorotate{} 在iOS 16中不再起效果!不管返回YES还是NO都能转屏!!!反而是需要控制- (UIInterfaceOrientationMask)supportedInterfaceOrientations有效果,神奇不!!
据我实验在iOS 16中转屏的时候,直接获取设备方向:
UIDeviceOrientation orientation = [UIDevice currentDevice].orientation;
将返回UIDeviceOrientationUnknown,是不是神坑!!!!!
- if ([[UIDevice currentDevice] respondsToSelector:@selector(setOrientation:)]) {
- SEL selector = NSSelectorFromString(@"setOrientation:");
- NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:[UIDevice instanceMethodSignatureForSelector:selector]];
- [invocation setSelector:selector];
- [invocation setTarget:[UIDevice currentDevice]];
- int val = UIDeviceOrientationPortrait;
- [invocation setArgument:&val atIndex:2];
- [invocation invoke];
- }
- [UIViewController attemptRotationToDeviceOrientation];
当然,据实验所知,iOS 16以后也能用,只不过会有日志警告。如果你用Xcode 14 ,此方案在iOS 16上就不好用了!
- if (@available(iOS 16.0, *)) {
- // setNeedsUpdateOfSupportedInterfaceOrientations 方法是 UIViewController 的方法
- [self setNeedsUpdateOfSupportedInterfaceOrientations];
- NSArray *array = [[[UIApplication sharedApplication] connectedScenes] allObjects];
- UIWindowScene *scene = [array firstObject];
- // 屏幕方向
- UIInterfaceOrientationMask orientation = isLaunchScreen ? UIInterfaceOrientationMaskLandscape: UIInterfaceOrientationMaskPortrait;
- UIWindowSceneGeometryPreferencesIOS *geometryPreferencesIOS = [[UIWindowSceneGeometryPreferencesIOS alloc] initWithInterfaceOrientations:orientation];
- // 开始切换
- [scene requestGeometryUpdateWithPreferences:geometryPreferencesIOS errorHandler:^(NSError * _Nonnull error) {
- NSLog(@"错误:%@", error);
- }];
- }
当然如果你没有升级到Xcode 14,还可以这样写:(据我实验不好用,只能横屏,不能再转到竖屏,不推荐此方案!)
- if (@available(iOS 16.0, *)) {
- void (^errorHandler)(NSError *error) = ^(NSError *error) {
- NSLog(@"错误:%@", error);
- };
- #pragma clang diagnostic push
- #pragma clang diagnostic ignored "-Warc-performSelector-leaks"
- SEL supportedInterfaceSelector = NSSelectorFromString(@"setNeedsUpdateOfSupportedInterfaceOrientations");
- [self performSelector:supportedInterfaceSelector];
- NSArray *array = [[UIApplication sharedApplication].connectedScenes allObjects];
- UIWindowScene *scene = (UIWindowScene *)[array firstObject];
- Class UIWindowSceneGeometryPreferencesIOS = NSClassFromString(@"UIWindowSceneGeometryPreferencesIOS");
- if (UIWindowSceneGeometryPreferencesIOS) {
- SEL initWithInterfaceOrientationsSelector = NSSelectorFromString(@"initWithInterfaceOrientations:");
- UIInterfaceOrientationMask orientation = UIInterfaceOrientationMaskPortrait;
- id geometryPreferences = [[UIWindowSceneGeometryPreferencesIOS alloc] performSelector:initWithInterfaceOrientationsSelector withObject:@(orientation)];
- if (geometryPreferences) {
- SEL requestGeometryUpdateWithPreferencesSelector = NSSelectorFromString(@"requestGeometryUpdateWithPreferences:errorHandler:");
- if ([scene respondsToSelector:requestGeometryUpdateWithPreferencesSelector]) {
- [scene performSelector:requestGeometryUpdateWithPreferencesSelector withObject:geometryPreferences withObject:errorHandler];
- }
- }
- }
- #pragma clang diagnostic pop
- }
横屏按钮点击事件:
- if (@available(iOS 16, *)) {
-
- _landscape = YES;
- [self setNeedsUpdateOfSupportedInterfaceOrientations];
- }
竖屏按钮点击事件:
- if (@available(iOS 16, *)) {
-
- _landscape = NO;
- [self setNeedsUpdateOfSupportedInterfaceOrientations];
- }
再加一个方法:
- - (UIInterfaceOrientationMask)supportedInterfaceOrientations {
-
- if (_landscape)
- {
- //横屏
- return UIInterfaceOrientationMaskLandscape;
- }else
- {
- //竖屏
- return UIInterfaceOrientationMaskPortrait;
- }
- }
极简单的代码即可完成你想要的效果。
如果你的[self setNeedsUpdateOfSupportedInterfaceOrientations] 没起任何作用,你可以需要在主线程main queue中调用它!
