应用程序可以自动旋转到iPad上的纵向横向，但不能在iPhone上旋转

Question

我想使ViewController成为一个肖像和ViewController B的景观。当它运行时，即使我将应用程序代理设置为横向更改，所有内容都会显示。你能告诉我该怎么做吗？以下是我的工作..

ViewController A将查看控制器B：

        AppDelegate *appDelegate = (AppDelegate *) [UIApplication sharedApplication].delegate;
        appDelegate.restrictRotation = TRUE;


        MapViewController * sliderVC =      [[MapViewController alloc] init ];

        sliderVC.modalPresentationStyle = UIModalPresentationCurrentContext;
        [self presentViewController:sliderVC animated:NO completion:nil];
        sliderVC.view.backgroundColor =  [UIColor clearColor];

AppDelegate.m

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
    if(self.restrictRotation)//set the bool value to view controller which you want to load in landscape
        return UIInterfaceOrientationMaskLandscapeRight;
    else
        return UIInterfaceOrientationMaskPortrait;
}

Answer 1

确保您支持所需的方向：

项目＆gt;目标＆gt;一般

Answer 2

您应该在View Controller B上覆盖以下方法：

func shouldAutorotate() -> Bool
func supportedInterfaceOrientations() -> Int
func preferredInterfaceOrientationForPresentation() -> UIInterfaceOrientation

您在AppDelegate中覆盖的方法适用于整个应用。

Answer 3

我建议您查看相关文档。

Multiple Orientations

基本上这是你需要为所有视图控制器做的事情：

#pragma mark Orientation handling

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown);
}

-(BOOL)shouldAutorotate
{
    return YES;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return (UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown);
}
