Question

Bellow我有一些代码放在我的 AppDelegate.h＆amp; .M 即可。此代码检测我的MPMoviePlayerController何时进入全屏并通过通知退出全屏。调用通知后，它会将allowRotation设置为yes，然后允许用户旋转视图。然而，一旦用户激动全屏并且仍然处于特定的状态，则播放器解散，但在用户观看视频的同时留下视图。这是因为调用了退出全屏通知但未调用-(NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window。因此，当用户旋转设备时，它只会重新旋转到端口速率。但我不希望这样，并希望在调用通知后立即轮换。有人可以帮忙吗？

这是我的代码：

·H

#import <UIKit/UIKit.h>

@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;
@property (nonatomic) BOOL allowRotation;


@end

的.m @synthesize allowRotation;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayerWillEnterFullscreenNotification:) name:MPMoviePlayerWillEnterFullscreenNotification object:nil];

        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(MPMoviePlayerDidExitFullscreen:) name:MPMoviePlayerDidExitFullscreenNotification object:nil];
    allowRotation = NO;
    return YES;
}

- (void) MPMoviePlayerDidExitFullscreen:(NSNotification*)notification {
    NSLog(@"calling1");
    self.allowRotation = NO;
}


- (void) moviePlayerWillEnterFullscreenNotification:(NSNotification*)notification {
    NSLog(@"calling");
    self.allowRotation = YES;
}
-(NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
    if (self.allowRotation == YES) {
        return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight;
    }
    else if (self.allowRotation == NO){
        NSLog(@"portrait");
    return UIInterfaceOrientationMaskPortrait;
    }

}

当UI布局在开始时完成时调用接口旋转调用，并且稍后动态更改它不会改变方向。

用户重新进入后如何旋转视图？
