隐藏tabBar显示Ios7中的黑条

Question

我正在使用此代码隐藏TabBar:

self.tabBarController.tabBar.hidden=YES;

我在我的项目中隐藏了tabBarController.但它在Ios7的视图底部显示了黑条.当我回到相同的视图时它看起来很好.任何帮助将不胜感激.

Answer 1

注意:它仅适用于iOS6和7.

在iOS 7中,为了扩展可点击区域并在隐藏的UITabBar上隐藏黑条,你应该为你的UIViewController启用'Extend Edges - Under Opaque Bars'选项.

或者您可以以编程方式设置此属性:

[self setExtendedLayoutIncludesOpaqueBars:YES]

以下是隐藏或移动TabBar for iOS 6/7的代码示例:

UITabBarController *bar = [self tabBarController];
if ([self respondsToSelector:@selector(setExtendedLayoutIncludesOpaqueBars:)]) {
    //iOS 7 - hide by property
    NSLog(@"iOS 7");
    [self setExtendedLayoutIncludesOpaqueBars:YES];
    bar.tabBar.hidden = YES;
} else {
    //iOS 6 - move TabBar off screen
    NSLog(@"iOS 6");
    CGRect screenRect = [[UIScreen mainScreen] bounds];
    float height = screenRect.size.height;
    [self moveTabBarToPosition:height];
}

//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];
        }
    }
}

下一个代码适合我

- (void)showTabBar {
[self.tabBar setTranslucent:NO];
[self.tabBar setHidden:NO];
}

- (void)hideTabBar {
    [self.tabBar setTranslucent:YES];
    [self.tabBar setHidden:YES];
}

Answer 3

试试这个:

- (BOOL)hidesBottomBarWhenPushed {
     return YES;
}

Answer 4

To showTabbar:

- (void)showTabBar:(UITabBarController *) tabbarcontroller
    {
            //[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, 521, view.frame.size.width, view.frame.size.height)];

                    }
            else
                    {
                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 521)];
                    }
                }

            // [UIView commitAnimations];
    }

To hide Tabbar:
 - (void)hideTabBar:(UITabBarController *) tabbarcontroller
    {
            //[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, 568, view.frame.size.width, view.frame.size.height)];
                    }
            else
                    {
                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 568)];
                    }
                }

            //[UIView commitAnimations];
    }
