This article is about how to show and hide the animation effects of TabBar in iOS. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

The system has no animation effect to show and hide tabBar, how to add animation effect to it?

Here is the sample code:

/ / hide the tag bar

-(void) hiddenTheTabBar

{

If (! [[NSUserDefaults standardUserDefaults] boolForKey:@ "isHiddenTabBar"]) {

For (UIView * v in [self.view subviews]) {

If ([v isKindOfClass: [UITabBar class]]) {

[UIView animateWithDuration:0.5f delay:0.0f options:UIViewAnimationOptionCurveEaseOut animations: ^ () {

CGRect frame = v.frame

Frame.origin.y + = 49.0f

V.frame = frame

} completion:nil]

} else {

[UIView animateWithDuration:0.5f delay:0.0f options:UIViewAnimationOptionCurveEaseOut animations: ^ () {

CGRect frame = v.frame

Frame.size.height + = 49.0f

V.frame = frame

} completion:nil]

}

}

[[NSUserDefaults standardUserDefaults] setBool:YES forKey:@ "isHiddenTabBar"]

}

}

/ / display the label bar

-(void) showTheTabBar

{

If ([[NSUserDefaults standardUserDefaults] boolForKey:@ "isHiddenTabBar"]) {

For (UIView * v in [self.view subviews]) {

If ([v isKindOfClass: [UITabBar class]]) {

[UIView animateWithDuration:0.3f delay:0.0f options:UIViewAnimationOptionCurveEaseOut animations: ^ () {

CGRect frame = v.frame

Frame.origin.y-= 49.0f

V.frame = frame

} completion:nil]

} else {

[UIView animateWithDuration:0.3f delay:0.0f options:UIViewAnimationOptionCurveEaseOut animations: ^ () {

CGRect frame = v.frame

Frame.size.height-= 49.0f

V.frame = frame

} completion:nil]

}

}

[[NSUserDefaults standardUserDefaults] setBool:NO forKey:@ "isHiddenTabBar"]

}

}
