IOS 关于某个界面某个视图全屏以及状态栏横向问题

注：文章看过读过很多，从来没有自己写过，有写的不好的地方请谅解！谢谢

由于项目中APP不支持横屏，但是单一某个视频界面需要支持横屏以及状态栏横向

正常显示（竖屏）

注：由于为公司项目，当前截图只是截取需要操作的界面的View

横屏：

为了更好的理解这个视图，我画了一个图还解释（需要横屏显示的及绿色部分，在竖屏正常显示的时候界面就如下）：

废话不多少，直接上代码：

我的当前项目的需求是点击全屏按钮之后，横屏显示界面

#pragma mark -- 全屏按钮

- (void)mainScreenAction:(UIButton *)btn{

DLog(@"全屏按钮");

isHalfScreen= !isHalfScreen;

if(isHalfScreen){//进入全屏

[self enterFullscreen];

}else{

//退出全屏

[self exitFullscreen];

}

}

//进入全屏

#pragma mark -- 进入全屏

- (void)enterFullscreen {

/** 记录进入全屏前的parentView和frame*/

openGLView.movieViewParentView = openGLView.superview;

openGLView.movieViewFrame = openGLView.frame;

/** movieView移到window上*/

CGRect rectInWindow = [openGLView convertRect:openGLView.bounds toView:[UIApplication sharedApplication].keyWindow];

[openGLView removeFromSuperview];

openGLView.frame = rectInWindow;

[[UIApplication sharedApplication].keyWindow addSubview:openGLView];

[sliderView removeFromSuperview];

/** 执行动画*/

[UIView animateWithDuration:0.5 animations:^{

openGLView.transform = CGAffineTransformMakeRotation(M_PI_2);

openGLView.bounds = CGRectMake(0, 0, CGRectGetHeight(openGLView.superview.bounds), CGRectGetWidth(openGLView.superview.bounds));

openGLView.center = CGPointMake(CGRectGetMidX(openGLView.superview.bounds), CGRectGetMidY(openGLView.superview.bounds));

} completion:^(BOOL finished) {

//退出全屏按钮位置

sliderView.frame = CGRectMake(openGLView.bounds.size.width-65, openGLView.bounds.size.height-50, 40, 40);

[mainScreenBtn setImage:[UIImage imageNamed:@"退出全屏.png"] forState:UIControlStateNormal];

[openGLView addSubview:sliderView];

}];

[self refreshStatusBarOrientation:UIInterfaceOrientationLandscapeRight];

//显示状态栏

[[UIApplication sharedApplication] setStatusBarHidden:FALSE];

[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];

}

//退出全屏

#pragma mark -- 退出全屏

- (void)exitFullscreen {

CGRect frame11 = [openGLView.movieViewParentView convertRect:openGLView.movieViewFrame toView:[UIApplication sharedApplication].keyWindow];

[UIView animateWithDuration:0.5 animations:^{

[sliderView removeFromSuperview];

openGLView.transform = CGAffineTransformIdentity;

openGLView.frame = frame11;

} completion:^(BOOL finished) {

/*

* movieView回到小屏位置

*/

[openGLView removeFromSuperview];

openGLView.frame = openGLView.movieViewFrame;

[openGLView.movieViewParentView addSubview:openGLView];

//退出全屏按钮位置

sliderView.frame = CGRectMake(openGLView.bounds.size.width-65, openGLView.bounds.size.height-50, 40, 40);

[mainScreenBtn setImage:[UIImage imageNamed:@"全屏.png"] forState:UIControlStateNormal];

[openGLView addSubview:sliderView];

}];

[self refreshStatusBarOrientation:UIInterfaceOrientationPortrait];

//显示状态栏

[[UIApplication sharedApplication] setStatusBarHidden:FALSE];

[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];

}

- (void)refreshStatusBarOrientation:(UIInterfaceOrientation)interfaceOrientation {

[[UIApplication sharedApplication] setStatusBarOrientation:interfaceOrientation animated:YES];

}

这里在实现了视图界面横屏之后，会出现状态栏依然是竖屏显示的状态。所以还要做以下操作（因为项目框架是UINavigationController搭建的，故在两个控制器里都需要加以下代码）

UINavigationController：

- (UIInterfaceOrientationMask)supportedInterfaceOrientations {

return [[self.viewControllers lastObject] supportedInterfaceOrientations];

}

- (BOOL)shouldAutorotate{

return [[self.viewControllers lastObject] shouldAutorotate];

}

---

然后在需要横屏的控制器里加入代码

- (BOOL)shouldAutorotate {

return NO;

}

具体代码可以参照demo
