请不要建议我在1个构建中的ios 4.3-6.0上进行旋转是一个坏主意，因为我告诉过很多次并且没有听我讲。
在项目设置中，我已经确定要支持所有界面方向。
现在，我正在使用iphone4在ios6上进行测试。从应用程序委托开始，它是一个代码，如下所示：
mainController = [[MainViewController alloc] initWithNibName:nil bundle:nil];
navigationController=[[RotatingNavigationController alloc] initWithRootViewController:mainController];
navigationController.navigationBar.hidden =true;
// ios: 4 and 5
//[window addSubview:navigationController.view];
//ios6:
window.rootViewController = navigationController;
[window makeKeyAndVisible];
因此，我做了2个自定义类，在可能的情况下，推荐使用自定义类进行自动旋转，因为它们可以解决问题。
RotatingNavigationController是一个自定义
UINavigationController，具有一些丑陋的代码，但是我已经从该论坛收集了这些部分，因此应该允许它发布：@implementation RotatingNavigationController
- (id)init {
self = [super init];
if (self) {
self.view.autoresizesSubviews = YES;
[self.view setAutoresizingMask:(UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth)];
}
return self;
}
// ios6 require this method for rotation detection, available from ios5, ios4.3 not available: sux
//- (void)viewWillLayoutSubviews
//{
//UIInterfaceOrientation statusBarOrientation = [UIApplication sharedApplication].statusBarOrientation;
//[[NSNotificationCenter defaultCenter] postNotificationName:UIDeviceOrientationDidChangeNotification object:nil];
// [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(orientationChanged:) name:UIDeviceOrientationDidChangeNotification object:nil];
/*
if(UIInterfaceOrientationIsLandscape(statusBarOrientation)){
[self willRotateToInterfaceOrientation: statusBarOrientation duration: 0.3 ];
}
else{
[self willRotateToInterfaceOrientation: statusBarOrientation duration: 0.3 ];
}
*/
//}
//ios 4.3 and ios 5.0, at ios6 it isn't called by iOS...sux
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration{
[self.visibleViewController willRotateToInterfaceOrientation:toInterfaceOrientation duration:duration];
}
// //ios 4.3 and ios 5.0, at ios6 need different methods, which sux
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return YES;
}
//Autorotation is changing in iOS 6. In iOS 6, the shouldAutorotateToInterfaceOrientation: method of UIViewController is deprecated. In its place, you should use the supportedInterfaceOrientationsForWindow: and shouldAutorotate methods.
// ios6
- (NSUInteger)supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
return UIInterfaceOrientationMaskAll;
}
// ios6
- (BOOL)shouldAutorotate
{
return YES;
}
// ios6
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
return UIInterfaceOrientationMaskPortrait;
}
@end
这应该正确生成自动旋转通知，我认为他可以完成工作。
MainViewController是自定义的UIViewController。只是为了确保我已经复制粘贴了代码：
// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
// return (interfaceOrientation == UIInterfaceOrientationPortrait);
return YES;
}
// ios6:
- (NSUInteger)supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
return UIInterfaceOrientationMaskAll;
}
// ios6
- (BOOL)shouldAutorotate
{
return YES;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
return UIInterfaceOrientationMaskPortrait;
}
他的工作是根据设备状态（旋转）更改不同的UIViewController
我在某处有一个菜单屏幕，该菜单屏幕具有不同的xib，但是h和m文件也是如此（因为具有不同的元素，而这些元素在Portait或Landscape中不出现。（我无权更改整个体系结构）
代码的一部分-这应该是一些问题，我认为是在此Maincontroller中：
#pragma mark
#pragma mark Rotation
- (void)orientationChanged:(NSNotification *)notification
{
UIDeviceOrientation deviceOrientation = [UIDevice currentDevice].orientation;
UIInterfaceOrientation statusBarOrientation = [UIApplication sharedApplication].statusBarOrientation;
if(deviceOrientation == UIDeviceOrientationFaceUp || deviceOrientation == UIDeviceOrientationFaceDown){
if(debug){
NSLog(@"Nothing to change because it is gone to Flat");
}
return;
}
NSArray *viewControllers = [self.navigationController viewControllers];
if (UIDeviceOrientationIsLandscape(deviceOrientation)){
//if(debug)
// NSLog(@"Portait -> Landscape size : %3.0fw, %3.0fh", self.view.bounds.size.width, self.view.bounds.size.height);
id lastviewController = viewControllers.lastObject;
// check what is there:
if([lastviewController isKindOfClass:[MenuController class]]){
[self.navigationController popViewControllerAnimated:NO];
[self.navigationController pushViewController:menuLandscape animated:NO];
NSLog(@"poped Menu Portrait, pushed Menu Landscape");
}
...
else if(UIDeviceOrientationIsPortrait(deviceOrientation)){
//else if(UIInterfaceOrientationIsLandscape(statusBarOrientation)){
//if(debug)
// NSLog(@"Landscape -> Portait , size : %3.0fw, %3.0fh", self.view.bounds.size.width, self.view.bounds.size.height);
id lastviewController = viewControllers.lastObject;
// check what is there:
if([lastviewController isKindOfClass:[MenuLandscapeController class]]){
[self.navigationController popViewControllerAnimated:NO];
[self.navigationController pushViewController:menuPortait animated:NO];
}
...
问题是：将景观倒出并推入肖像时，当其倒置时，但该肖像没有旋转，并且显示了损坏的布局。
我如何唤醒该控制器并告诉他该旋转了，因为它不是处于纵向模式？
感谢任何与我的问题有关的建议，除了架构更改之外，还有其他改进。
更新：
在app delgate时无济于事：
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
return UIInterfaceOrientationMaskAll;
}
来自其他答案的代码：presented here
更新2：
UIInterfaceOrientation statusBarOrientation = [UIApplication sharedApplication].statusBarOrientation;
出于某种原因不想采用
UIInterfaceOrientationPortraitUpsideDown = UIDeviceOrientationPortraitUpsideDown值，我认为需要解决。更新3：
仔细阅读两次，然后按ios6 release notes的第三
系统确定是否支持方向
与应用的返回值相交
supportedInterfaceOrientationsForWindow：方法，其值为
由最顶部的supportedInterfaceOrientations方法返回
全屏控制器。
现在再读一遍:)
最佳答案
将此类别添加到不会旋转的ViewController中
@implementation UINavigationController(Rotation)
-(NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskAll;
}
@end
