iOS 视频横竖屏窗口解决方案

1.其他界面是竖屏，有个界面只支持横屏

#pragma mark 强制横屏的方法

- (BOOL)shouldAutorotate {

returnNO;

}

- (UIInterfaceOrientationMask) supportedInterfaceOrientations {

returnUIInterfaceOrientationMaskLandscapeRight;

}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {

returnUIInterfaceOrientationLandscapeRight;

}

2.其他界面是竖屏，有个界面又要支持横屏又要支持竖屏

AppDelegate.h 增加 @property(nonatomic,assign)NSInteger allowRotation;//全局参数是否允许横竖屏切换

初始_allowRotaion = 0

#pragma mark 设置是否可以横竖屏切换

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

{

if(_allowRotation==1) {

returnUIInterfaceOrientationMaskAllButUpsideDown;//这个可以根据自己的需求设置旋转方向

}

else

{

return(UIInterfaceOrientationMaskPortrait);

}

}

在你需要的界面viewwillAppaear设置_allowRotaion  = 1

点击触发横屏代码

if([[UIDevicecurrentDevice]respondsToSelector:@selector(setOrientation:)]) {

SELselector =NSSelectorFromString(@"setOrientation:");

NSInvocation*invocation = [NSInvocationinvocationWithMethodSignature:[UIDeviceinstanceMethodSignatureForSelector:selector]];

[invocationsetSelector:selector];

[invocationsetTarget:[UIDevicecurrentDevice]];

intval =UIInterfaceOrientationLandscapeRight;

[invocationsetArgument:&valatIndex:2];

[invocationinvoke];

}
