 在实际生活应用中,我们希望用户在点击视频时一打开的时候就自动全屏播放,达到更加绚丽的视觉体验效果;

****** Appdelegate.h ** 类中***** 

#import <UIKit/UIKit.h> 

@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;

@property(nonatomic,assign)BOOL isFull;///<是否允许自动旋转

@end

 

》》》Appdelegate .m 文件

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

{

    if (!_isFull) {

        return UIInterfaceOrientationMaskPortrait;

    }else{

        return UIInterfaceOrientationMaskAllButUpsideDown;

    }

}

 

 

#import "ViewController.h"

#import "AppDelegate.h"

 

@interface ViewController ()<UIWebViewDelegate>{

    AppDelegate *app;

    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIWindowDidBecomeVisibleNotification object:nil];

}

 

-(void)playerWillExitFullscreen:(id)sender{

    NSLog(@"退出播放视频了");

    app.isFull=NO;

    

    /**

     下边方法的使用场景:

     如果点击视频,自动旋转为横屏播放状态,点击完成按钮,需要是程序变为竖屏状态,需要下边的代码

     */

    UIViewController *vc = [[UIViewController alloc]init];

    [self presentViewController:vc animated:NO completion:nil];

    [vc dismissViewControllerAnimated:NO completion:nil];

    

}
