iOS 8 强制横屏

最近用到视频播放功能:(Vitamio, 注:在Build Setting 里面的 Other Link Flag 添加-all_load)

iOS 8的屏幕旋转比较坑, 使用以下代码可以强制旋转

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{
    return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight );
}

- (BOOL)shouldAutorotate{
    return YES;
}

- (NSUInteger)supportedInterfaceOrientations{
    return UIInterfaceOrientationMaskAll;
}

//强制切换
- (void)switchToLandspance{
    [[UIDevice currentDevice] setValue:[NSNumber numberWithInteger:UIDeviceOrientationPortrait] forKey:@"orientation"];//这句话是防止手动先把设备置为横屏,导致下面的语句失效.
    [[UIDevice currentDevice] setValue:[NSNumber numberWithInteger:UIDeviceOrientationLandscapeLeft] forKey:@"orientation"];
}

注意: 需要项目支持横屏旋转(Project Setting 里的 Device Orientation)
