How to Hide Tab Bar Controller?

问题:

How to Hide Tab Bar Controller ? I want to hide the Tab Bar controller with double tap on UIImageView.

回答1:

Try this code:

[self.tabBarController.tabBar setHidden:YES];

where tabbarcontroller is needed to be defined...

EDIT

AppDelegateFileName *appDelegate = (AppDelegateFileName *) [[UIApplication sharedApplication] delegate];
[appDelegate.tabbarController.tabBar setHidden:YES];

before doing this make sure that you create a @property declaration of tabbarController in appDelegate .h file.

回答2:

If using Storyboards you can simply uncheck a checkbox in your ViewController's Attribute Inspector. It's called "Hide Bottom Bar on Push". Very convenient indeed, and no need to handle the showing of the tabBar again after navigating back from your tabBar-less viewController. I don't know in which XCode-version this was introduced, but it's there for XCode 6 + .

回答3:

Use TapGesture Recognizer to detect double taps on a UIIMageview. Then invoke a method on detecting the double double tap. Add the following line of code in that method.

self.tabBarController.tabBar.hidden=YES;

Hope this helps.

Use the code below to hide/show tab bar controller in animated style.
hiddenTabBar is a BOOL variable.

- (void) hidetabbar {

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.0];

    for(UIView *view in objtabbar.view.subviews)
    {

        if([view isKindOfClass:[UITabBar class]])
        {

            if (hiddenTabBar) {
                [view setFrame:CGRectMake(view.frame.origin.x, 431, view.frame.size.width, view.frame.size.height)];
            } else {
                [view setFrame:CGRectMake(view.frame.origin.x, 480, view.frame.size.width, view.frame.size.height)];
            }
        } else {
            if (hiddenTabBar) {
                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 431)];
            } else {
                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 480)];
            }

        }
    }

    [UIView commitAnimations];

    hiddenTabBar = !hiddenTabBar;
}

回答5:

UIViewController has a property

@property(nonatomic, readonly, retain) UITabBarController *tabBarController

which you can set:

self.tabBarController.tabBar.hidden = YES;

回答6:

Swift 2.1:

self.tabBarController!.tabBar.hidden = true

回答7:

Try this when you push the view to the new view:

self.tabbarconroller.tabbar.hidden = YES;

回答8:

Objective-C

[self.tabBarController.tabBar setHidden:YES];

Swift 3

self.tabBarController?.tabBar.isHidden = true

Swift 2

self.tabBarController?.tabBar.hidden = true

If you want to change with animation you could use this code:

extension UITabBarController {

func set(visible: Bool, animated: Bool, completion: ((Bool)->Void)? = nil ) {

    guard isVisible() != visible else {
        completion?(true)
        return
    }

    let offsetY = tabBar.frame.size.height
    let duration = (animated ? 0.3 : 0.0)

    let beginTransform:CGAffineTransform
    let endTransform:CGAffineTransform

    if visible {
        beginTransform = CGAffineTransform(translationX: 0, y: offsetY)
        endTransform = CGAffineTransform.identity
    } else {
        beginTransform = CGAffineTransform.identity
        endTransform = CGAffineTransform(translationX: 0, y: offsetY)
    }

    tabBar.transform = beginTransform
    if visible {
        tabBar.isHidden = false
    }

    UIView.animate(withDuration: duration, animations: {
        self.tabBar.transform = endTransform
    }, completion: { compete in
        completion?(compete)
        if !visible {
            self.tabBar.isHidden = true
        }
    })
}

func isVisible() -> Bool {
    return !tabBar.isHidden
}
}
