Iphone iPad模态视图控制器以纵向方式运行,即使它';城市景观
我在横向模式下演示ModalViewController时遇到一些困难。基本上,它以正确的界面方向显示,并且仅当设备保持在横向模式下时才旋转,但viewcontroller的行为就好像它处于纵向模式一样 我是这样呈现模态的Iphone iPad模态视图控制器以纵向方式运行,即使它';城市景观,iphone,objective-c,ios,ipad,rotation,Iphone,Objective C,Ios,Ipad,Rotation,我在横向模式下演示ModalViewController时遇到一些困难。基本上,它以正确的界面方向显示,并且仅当设备保持在横向模式下时才旋转,但viewcontroller的行为就好像它处于纵向模式一样 我是这样呈现模态的 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[UIWindo

基本上,loginViewController的行为就像它处于纵向模式一样。我在这个视图上有两个文本字段,当我点击其中一个时,我想向上移动视图,这样键盘就不会显示在文本字段上。为了做到这一点,我必须修改frame.origin.x而不是y,因为轴是反转的(视图的行为类似于纵向),这会导致很多问题
编辑:
如果我将LoginViewController上的模式演示样式更改为UIModalPresentationPageSheet,它将按预期工作,因此仅全屏模式存在一些问题
第二次编辑:
我已经把代码精简到了最基本的部分。我甚至不再提供一个模态视图控制器,只是将该视图控制器初始化为根视图控制器,但这仍然在发生
应用程序代表:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.viewController = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil];
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
return YES;
}
在我的视图控制器中:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
NSLog(@"%@",NSStringFromCGRect( self.view.frame));
return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}
改变这个
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
NSLog(@"%@",NSStringFromCGRect(self.view.frame));
return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}
进入这个
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
NSLog(@"%@",NSStringFromCGRect(self.view.frame));
return YES;
}
x/y反转的帧是“特征”;)您缺少一个
convertRect:fromView
。看一下不同的视图
在您的情况下,需要将键盘框架的矩形转换为视图控制器的主视图。没有看到你的键盘框架,我不太清楚,但可能是这样的:
[self.view convertRect:keyboardFrame fromView:keyboardView];
好的,我终于找到了一种方法让它正常工作。如果您只是创建一个新的视图控制器,并呈现它,它似乎将始终处于反转状态。我找到的修复方法是将视图控制器放在导航控制器中
LoginViewController *lvc = [[LoginViewController alloc] initWithNibName:@"LoginViewController" bundle:[NSBundle mainBundle]];
UINavigationController *nvc = [[UINavigationController alloc] initWithRootViewController:lvc];
nvc.navigationBarHidden = YES;
lvc.modalPresentationStyle = UIModalPresentationFullScreen;
lvc.parentView = self.navController.view;
[self.window.rootViewController presentModalViewController:nvc animated:NO];
它也有同样的行为。此外,我希望它被锁定在横向中,这样即使它有效,也不能真正解决我的问题。您是否已将所有视图控制器中的值更改为“是”?是,它仍具有相同的行为。但即使它成功了,也毫无意义,因为该应用程序应该只在景观中运行,请尝试将其更改为返回interfaceOrientation=UIInterfaceOrientation和景观Right | UIInterfaceOrientation和景观Left;对不起,我可能不明白你在说什么。我使用的是标准的iOS键盘。画面一直在倒转,这就是我的问题。
