推荐答案

注意：它是解决方案仅限iOS6和7。

NOTE: It is solution for iOS6 and 7 only.

在iOS 7中，为了扩展可点击区域并在隐藏的UITabBar上隐藏黑条，您应该为您启用扩展边缘 - 在不透明条形下选项UIViewController中。

In iOS 7 to extend clickable area and hide black bar on place of hidden UITabBar you should enable 'Extend Edges - Under Opaque Bars' option for you UIViewController.

或者你可以通过编程方式设置这个属性：

Or you can set this property programmatically:

[self setExtendedLayoutIncludesOpaqueBars：YES]

[self setExtendedLayoutIncludesOpaqueBars:YES]

下面是隐藏或移动TabBar for iOS 6/7的代码示例：

Here is example of code that hide or move TabBar for iOS 6/7:

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];
        }
    }
}
