实现iOS全局禁止横屏，但kxmovie全屏横屏播放视频

参考我转载的文章
iOS 全局禁止横屏，但UIWebView 全屏横屏播放视频的解决办法

我本身项目时用FFMpeg ＋ kxmovie 来播放视频

实现为如下：

1，AppDelegate 类添加参数，控制旋屏

// AppDelegate.h

#import <UIKit/UIKit.h>

@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;

@property (nonatomic, assign) BOOL allowRotation;/*** 是否允许横屏的标记 */

@end

// AppDelegate.m

实现协议的函数

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

//去限制只播放才横屏，其他节目都是竖屏

if (self.allowRotation) {

return UIInterfaceOrientationMaskAll;

}

return UIInterfaceOrientationMaskPortrait;

}

2，KxMovieViewController 类添加进入全屏和退出全屏的函数，在初始化和返回的事件中调用

- (void)begainFullScreen {//进入全屏

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

appDelegate.allowRotation = YES;

}

- (void)endFullScreen {//退出全屏

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

appDelegate.allowRotation = NO;

//强制归正：

if ([[UIDevice currentDevice] respondsToSelector:@selector(setOrientation:)]) {

SEL selector = NSSelectorFromString(@"setOrientation:");

NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:[UIDevice instanceMethodSignatureForSelector:selector]];

[invocation setSelector:selector];

[invocation setTarget:[UIDevice currentDevice]];

int val =UIInterfaceOrientationPortrait;

[invocation setArgument:&val atIndex:2];

[invocation invoke];

}

}

在初始化事件中调用

- (id) initWithContentPath: (NSString *) path parameters: (NSDictionary *) parameters {

NSAssert(path.length > 0, @"empty path");

[self begainFullScreen];//进入全屏

....

....

....

}

在返回事件中调用

- (void) doneDidTouch: (id) sender

{

if (self.presentingViewController || !self.navigationController)

[self dismissViewControllerAnimated:YES completion:nil];

else

[self.navigationController popViewControllerAnimated:YES];

[self endFullScreen]; //退出全屏，而且将屏幕强制为竖屏，这句只能放在返回之后，之前会导致crash，因为旋屏设置 冲突

}

结果大致可以接受，但不够理想，因为kxmovie返回后可以看到原界面从横屏转为竖屏的动画，姑且这样吧。如果看官有好的方法，还请不吝赐教！！！
