iOS 6 中的 iOS 隐藏标签栏会创建黑条(修复 iOS 6 会破坏 iOS 7！) [英] iOS Hiding tab bar in iOS 6 creates black bar (fix for iOS 6 breaks iOS 7!)
问题描述
我有一个选项卡式应用程序，在一个选项卡中有一个 UIWebView.当我将设备旋转到横向时，我已将 UIWebView 设为全屏，同时隐藏状态和标签栏.
I've got a tabbed application and in one tab there is a UIWebView. When I rotate the device to landscape I've made the UIWebView full screen while hiding the status and tab bar.
我已经让它在 iOS 6 中工作 - 最初当旋转和隐藏标签栏时，它会在标签栏所在的地方留下一个黑色空间，所以 fHeight 代码修复了这个问题.然而，在 iOS 6 上它运行良好，但现在它实际上产生了 iOS 6 的黑条问题！！有什么解决方法的想法吗?
I've got it working in iOS 6 - originally when rotating and hiding the tab bar it would leave a black space where the tab bar was, so the fHeight code fixes this. However, on iOS 6 it worked perfectly, but now it actually creates the black bar problem iOS 6 was having!! Any ideas for a workaround to this?

我尝试过使用它，但我不确定如何正确传递视图 - 我尝试过 self.view 和 webView 等，但我无法让它工作在 iOS 6 和 7 上！任何想法都会非常有帮助！如果您需要更多信息，请告诉我
I've tried using this but I'm not sure how to pass in the view properly - I've tried self.view and webView and others but I can't get it to work on both iOS 6 and 7! Any kind of idea at all would be really helpful! Let me know if you need more info

我最终得到了这个工作，但花了一段时间.它源于我的原始代码和 JRG 开发人员的一些工作的混合.
I eventually got this working, but it took a while. It stemmed from a mixture of my original code and some of JRG-Developers work.
- (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];
}
}
}
在我的情况下，这是针对我的 web 视图，但理论上你可以给它任何视图.适用于 iOS 6 和 7
In my case this is for my webview but theoretically you can give it any view. Works in iOS 6 and 7
