希望屏幕(UI)上的所有内容都能够从左到右旋转,反之亦然。
我该怎么做呢?这是私人的吗?
我知道
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {}
让你说出用户界面可以有哪些方向,但有没有办法一次只强制一个?
干杯

在iOS [[UIDevice currentDevice] setDeviceOrientation:UIDeviceOrientationSomeOrientation]
中,方法不存在。但我们可以使用状态栏旋转视图,为此:
- (void)showAlbum {
// check current orientation
if ([[UIApplication sharedApplication] statusBarOrientation] != UIInterfaceOrientationLandscapeLeft) {
// no, the orientation is wrong, we must rotate the UI
self.navigationController.view.userInteractionEnabled = NO;
[UIView beginAnimations:@"newAlbum" context:NULL];
[UIView setAnimationDelegate:self];
// when rotation is done, we can add new views, because UI orientation is OK
[UIView setAnimationDidStopSelector:@selector(addAlbum)];
// setup status bar
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft animated:NO];
// rotate main view, in this sample the view of navigation controller is the root view in main window
[self.navigationController.view setTransform: CGAffineTransformMakeRotation(M_PI / 2)];
// set size of view
[self.navigationController.view setFrame:CGRectMake(0, 0, 748, 1024)];
[UIView commitAnimations];
} else {
[self addAlbum];
}
}

我在这方面取得了成功:
if (self.interfaceOrientation != UIInterfaceOrientationPortrait) {
// http://stackoverflow.com/questions/181780/is-there-a-documented-way-to-set-the-iphone-orientation
// http://openradar.appspot.com/radar?id=697
// [[UIDevice currentDevice] setOrientation:UIInterfaceOrientationPortrait]; // Using the following code to get around apple's static analysis...
[[UIDevice currentDevice] performSelector:NSSelectorFromString(@"setOrientation:") withObject:(id)UIInterfaceOrientationPortrait];
}

调用该方法以确定您的界面是否应自动旋转到给定的旋转(即让UIKit执行艰苦的工作,而不是手动执行)。
因此,如果您希望自己的应用仅在横向工作,则可以使用以下方法实现该方法的主体:
return UIInterfaceOrientationIsLandscape(interfaceOrientation);
如果您希望自动界面可以自动旋转到所有方向
return YES;
这就是你问的问题吗?

如果你提出一个实现-shouldAutorotateToInterfaceOrientation:
的模态视图控制器只支持一个方向,整个界面将自动强制进入它。我不认为有办法以编程方式改变方向。

这种简单的方法也适用:
[[UIApplication sharedApplication] setStatusBarHidden:YES];
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight];
并返回:
[[UIApplication sharedApplication] setStatusBarHidden:NO];
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait];

在Swift中将方向更改为肖像:
UIDevice.currentDevice().setValue(UIInterfaceOrientation.Portrait.rawValue, forKey: "orientation")

这是通过以下方式解决的:Guntis Treulands https://stackoverflow.com/a/10146270/894671
//-----------------------------------
// FORCE PORTRAIT CODE
//-----------------------------------
[[UIApplication sharedApplication] setStatusBarOrientation:UIDeviceOrientationPortrait animated:NO];
//present/dismiss viewcontroller in order to activate rotating.
UIViewController *mVC = [[UIViewController alloc] init];
[self presentModalViewController:mVC animated:NO];
[self dismissModalViewControllerAnimated:NO];

if ([[UIDevice currentDevice] respondsToSelector:@selector(setOrientation:)]) {
objc_msgSend([UIDevice currentDevice], @selector(setOrientation:), UIInterfaceOrientationLandscapeLeft );
}

尽管这不是一个闲置的解决方案,但对我来说效果很好。
- (void)viewDidLoad
{
self.view.transform = CGAffineTransformIdentity;
self.view.transform = CGAffineTransformMakeRotation((M_PI * (90) / 180.0));
self.view.bounds = CGRectMake(0.0, 0.0, 480, 320);
}

不推荐使用suggested on a related thread shouldAutorotateToInterfaceOrientation
。较新的应用程序应该使用Apple的UIViewController Class Reference中描述的以下方法,直到它们自己被弃用为止:
shouldAutorotate
,preferredInterfaceOrientationForPresentation
;和attemptRotationToDeviceOrientation
。根据我的理解,最好使用不同的视图控制器来查看需要锁定(即具有首选)方向模式的视图,该模式与上一个不同。
