【问题描述】：

我想在不旋转设备的情况下单击按钮更改设备方向。

这是我的代码：

-(void)funcLandscapeBtnTapped:(UIButton *)button
 
      [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft animated:NO];

提前致谢。

【问题讨论】：

从上面的代码，应该发生什么？

什么都没有发生屏幕仅保持纵向模式。我希望屏幕将其方向更改为横向。

【参考方案1】：

试试这个代码，它的工作原理，

您的按钮操作：

isEnablePortraidMode = true;
NSNumber *number = [NSNumber numberWithInt:UIDeviceOrientationLandscapeLeft];
NSNumber *StatusBarOrientation = [NSNumber numberWithInt:UIInterfaceOrientationMaskLandscapeLeft];
[UIViewController attemptRotationToDeviceOrientation];
[[UIDevice currentDevice] setValue:number forKey:@"orientation"];
[[UIApplication sharedApplication] performSelector:@selector(setStatusBarOrientation:) withObject:StatusBarOrientation];
[UIViewController attemptRotationToDeviceOrientation];

并在 Appdelegate 中添加此方法

- (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
    if(isEnablePortraidMode)
    
        return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskLandscape;
     
    else
    
         return UIInterfaceOrientationMaskPortrait;
    

【参考方案2】：

试试这个

AppDelegate.h

@property BOOL restrictRotation;

AppDelegate.m

#define APPDELEGATE ((AppDelegate*)[[UIApplication sharedApplication] delegate])

- (UIInterfaceOrientationMask )application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window 

    if (self.restrictRotation == YES) 
        return UIInterfaceOrientationMaskLandscape;        
    
    else 
        if (isiPhone || isiPod) 
            return UIInterfaceOrientationMaskPortrait;
        else
            return UIInterfaceOrientationMaskLandscape;
        
    

YourViewController.m

-(void)funcLandscapeBtnTapped:(UIButton *)button

    APPDELEGATE.restrictRotation = YES;
        [[UIDevice currentDevice] setValue:
         [NSNumber numberWithInteger: UIInterfaceOrientationLandscapeRight]
                                    forKey:@"orientation"];
        [self shouldAutorotate];

- (BOOL)shouldAutorotate 
    UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];
    if ( orientation == UIInterfaceOrientationLandscapeRight
        | orientation == UIInterfaceOrientationLandscapeLeft)
    
        return NO;
    

    return YES;

现在如何在 AVPlayerviewcontroller 中获得默认的全屏按钮操作？它在我们显示PlaybackControls = true 时出现。
