请不要建议我在ios 4.3-6.0中进行一次旋转是一个坏主意,因为我多次告诉并且没有听我说。
在项目设置中,我已经设置了所有支持的界面方向,只是为了确保。
现在我正在用iphone4测试ios6。从app delegate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];
所以我做了2个自定义类,在自动旋转的情况下推荐这些类,并且问题已经解决了。
RotatingNavigationController是一个自定义的UINavigationController
有一些丑陋的代码,但是我已经从这个论坛中收集了这些部分,所以应该允许发布它:
@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
MainViewController
是自定义UIViewController
。
只是为了确保我已经复制粘贴代码:
// 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
我有一个菜单屏幕,它有不同的xib,但也有h和m文件(因为有不同的元素,它们没有出现在Portait或Landscape中。(我没有权力改变整个架构)
代码的一部分 - 这里应该是一些问题,我想在下面这个Maincontroller:
#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:景观被取出并被推倒,当倒置时,但是那些画面没有旋转,它显示出破损的布局。
如何唤醒该控制器并告诉他是时候旋转,因为它不处于纵向模式?
感谢任何与我的问题相关的建议,除了架构变更之外的任何改进。
更新
在app delgate的没有帮助添加:
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
return UIInterfaceOrientationMaskAll;
}
来自其他答案的代码:presented here
UPDATE2:
UIInterfaceOrientation statusBarOrientation = [UIApplication sharedApplication].statusBarOrientation;
出于某种原因不想取UIInterfaceOrientationPortraitUpsideDown = UIDeviceOrientationPortraitUpsideDown
值,我认为需要解决。
UPDATE3: 仔细阅读两次,第三次ios6 release notes
系统确定是否支持方向 与应用程序返回的值相交 supportedInterfaceOrientationsForWindow:带值的方法 由最顶层的supportedInterfaceOrientations方法返回 全屏控制器。
答案 0 :(得分:4)
将此类别添加到不旋转的viewcontroller
@implementation UINavigationController(Rotation)
-(NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskAll;
}
@end
