[英]iOS Hiding Status bar and tab bar in iOS 6 + 7
我有一个选项卡式应用程序,并且在一个选项卡中有一个UIWebView。 当我将设备旋转到横向时,我想在状态栏和选项卡栏上全屏显示该UIWebView。

好的,现在我可以在iOS 6中使用它了-最初在旋转和隐藏选项卡栏时,它会在选项卡栏所在的位置留下一个黑色空间,因此fHeight代码可以解决此问题。 但是,在iOS 6上,它运行良好,但是现在它实际上造成了iOS 6出现黑条的问题! 有什么解决方法的想法吗?
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration;
{
if(toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft || toInterfaceOrientation == UIInterfaceOrientationLandscapeRight) {
[self hideTabBar:self.tabBarController];
[[UIApplication sharedApplication] setStatusBarHidden:TRUE withAnimation:UIStatusBarAnimationSlide];
}
else
{
[self showTabBar:self.tabBarController];
[[UIApplication sharedApplication] setStatusBarHidden:FALSE withAnimation:UIStatusBarAnimationSlide];
}
}
- (void) hideTabBar:(UITabBarController *) tabbarcontroller
{
CGRect screenRect = [[UIScreen mainScreen] bounds];
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.5];
float fHeight = screenRect.size.height;
if( UIDeviceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation) )
{
fHeight = screenRect.size.width;
}
for(UIView *view in self.tabBarController.view.subviews)
{
if([view isKindOfClass:[UITabBar class]])
{
[view setFrame:CGRectMake(view.frame.origin.x, fHeight, view.frame.size.width, view.frame.size.height)];
}
else
{
[view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, fHeight)];
view.backgroundColor = [UIColor blackColor];
}
}
[UIView commitAnimations];
}
- (void) showTabBar:(UITabBarController *) tabbarcontroller
{
CGRect screenRect = [[UIScreen mainScreen] bounds];
float fHeight = screenRect.size.height - 49.0;
if( UIDeviceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation) )
{
fHeight = screenRect.size.width - 49.0;
}
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.5];
for(UIView *view in tabbarcontroller.view.subviews)
{
if([view isKindOfClass:[UITabBar class]])
{
[view setFrame:CGRectMake(view.frame.origin.x, fHeight, view.frame.size.width, view.frame.size.height)];
}
else
{
[view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, fHeight)];
}
}
[UIView commitAnimations];
}

我已尝试使用此功能,但不确定要传递哪种视图? 它应该适用于iOS 6和7
- (void)setTabBarHidden:(BOOL)hidden view:(UIView *)view animated:(BOOL)animated
{
if (self.tabBar.hidden == hidden)
return;
CGRect screenRect = [[UIScreen mainScreen] bounds];
float height = 0.0f;
if(UIDeviceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation))
{
height = screenRect.size.width;
}
else
{
height = screenRect.size.height;
}
if (!hidden)
{
height -= CGRectGetHeight(self.tabBar.frame);
}
void (^workerBlock)() = ^() {
self.tabBar.frame = CGRectMake(CGRectGetMinX(self.tabBar.frame), height, CGRectGetWidth(self.tabBar.frame), CGRectGetHeight(self.tabBar.frame));
view.frame = CGRectMake(CGRectGetMinX(view.frame), CGRectGetMinY(view.frame), CGRectGetWidth(view.frame), height);
};
void (^completionBlock)(BOOL finished) = ^(BOOL finished) {
self.tabBar.hidden = hidden;
};
if (animated)
{
[UIView animateWithDuration:0.25f animations:workerBlock completion:completionBlock];
}
else
{
workerBlock();
completionBlock(YES);
}
}
是的,请使用适当的UIViewController
旋转方法。 隐藏选项卡栏控制器很容易,但是在iOS 7上,状态栏更加困难。研究如何做到这一点,您应该会很好。
尝试...
-(void)viewWillAppear:(BOOL)animated
{
[self.navigationController setNavigationBarHidden:YES animated:animated];
[self setHidesBottomBarWhenPushed:YES];
[super viewWillApper:animated];
}
-(void)viewWillDisappear:(BOOL)animated
{
[self.navigationController setNavigationBarHidden:NO animated:animated];
[self setHidesBottomBarWhenPushed:NO];
[super viewWillDisapper:animated];
}
我之前做了这个工作,却忘记发布我的答案,因为我遇到了两个类似的问题! 适用于iOS 6和7
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation {
BOOL toLandscape = UIDeviceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation);
CGRect screenRect = [[UIScreen mainScreen] bounds];
void (^workerBlock)() = ^() {
[[UIApplication sharedApplication] setStatusBarHidden:toLandscape withAnimation:UIStatusBarAnimationSlide];
float height = toLandscape ? screenRect.size.width : screenRect.size.height - CGRectGetHeight(self.tabBarController.tabBar.frame);
float width = toLandscape ? screenRect.size.height : screenRect.size.width;
webView.frame = CGRectMake(CGRectGetMinX(webView.frame),
CGRectGetMinY(webView.frame),
width,
height);
[self moveTabBarToPosition:height];
};
[UIView animateWithDuration:0.25f animations:workerBlock];
}
//Moving the tab bar and its subviews offscreen so that top is at position y
-(void)moveTabBarToPosition:(int)y {
self.tabBarController.tabBar.frame = CGRectMake(self.tabBarController.tabBar.frame.origin.x, y, self.tabBarController.tabBar.frame.size.width, self.tabBarController.tabBar.frame.size.height);
for(UIView *view in self.tabBarController.view.subviews) {
if ([view isKindOfClass:[UITabBar class]]) {
[view setFrame:CGRectMake(view.frame.origin.x, y, view.frame.size.width, view.frame.size.height)];
} else {
[view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, y)];
view.backgroundColor = [UIColor blackColor];
}
}
}
就我而言,这是我的网络视图,但理论上您可以提供任何视图。 适用于iOS 6和7
