iOS - 视频播放处理全屏／横屏时候遇见的坑

视频播放想要全屏，使用shouldAutorotate方法禁止主界面，tabbar控制器横屏，导致push进入播放页面不能横屏的问题。。。

- (BOOL)shouldAutorotate {

return NO;

}

- (UIInterfaceOrientationMask)supportedInterfaceOrientations {

return UIInterfaceOrientationMaskAll;

}

后面解决方法：

- (void)fullScreenClick:(UIButton *)sender {

sender.selected = !sender.selected;

if (sender.isSelected) {

_backButton.hidden = YES;

[self forceOrientationLandscapeLeft];

} else {

_backButton.hidden = NO;

[self forceOrientationPortrait];

}

}

//MARK: -- 强制横屏

- (void)forceOrientationLandscapeLeft

{

AppDelegate *appdelegate=(AppDelegate *)[UIApplication sharedApplication].delegate;

appdelegate.isForcePortrait=NO;

appdelegate.isForceLandscape=YES;

[appdelegate application:[UIApplication sharedApplication] supportedInterfaceOrientationsForWindow:self.view.window];

YNCNavigationViewController *navi = (YNCNavigationViewController *)self.navigationController;

navi.interfaceOrientation = UIInterfaceOrientationMaskLandscape;

navi.interfaceOrientationMask = UIInterfaceOrientationMaskLandscape;

//设置屏幕的转向为横屏

[[UIDevice currentDevice] setValue:@(UIDeviceOrientationLandscapeLeft) forKey:@"orientation"];

//刷新

[UIViewController attemptRotationToDeviceOrientation];

}

//MARK: -- 强制竖屏

- (void)forceOrientationPortrait

{

AppDelegate *appdelegate=(AppDelegate *)[UIApplication sharedApplication].delegate;

appdelegate.isForcePortrait=YES;

appdelegate.isForceLandscape=NO;

[appdelegate application:[UIApplication sharedApplication] supportedInterfaceOrientationsForWindow:self.view.window];

YNCNavigationViewController *navi = (YNCNavigationViewController *)self.navigationController;

navi.interfaceOrientation = UIInterfaceOrientationPortrait;

navi.interfaceOrientationMask = UIInterfaceOrientationMaskPortrait;

//设置屏幕的转向为竖屏

[[UIDevice currentDevice] setValue:@(UIDeviceOrientationPortrait) forKey:@"orientation"];

//刷新

[UIViewController attemptRotationToDeviceOrientation];

}
