[英]How to hide the tabbar in a particular view?
Im working on tab bar application. 我在标签栏应用程序上工作。
in all the view tabbar carried. 在所有视图tabbar中进行。 ok.
好。
but in a particular one view i didn't want to display my tabbar. 但在一个特定的视图中,我不想显示我的tabbar。
when i pushed my view to the next view, tab bar carried to that view also. 当我将视图推到下一个视图时,标签栏也会进入该视图。
when i tried to hide this it shows white space for that view. 当我试图隐藏它时,它显示该视图的空白区域。
what to do.. thnaks in advance 怎么办..提前thnaks
try.... 尝试....
MyViewController *myController = [[MyViewController alloc] init];
//hide tabbar
myController.hidesBottomBarWhenPushed = YES;
//add it to stack.
[[self navigationController] pushViewController:myController animated:YES];
UITabBar is a top level view which means that almost all over views are underneath it. UITabBar是一个顶级视图,这意味着几乎所有视图都位于其下方。 Even UINavigationController seats bellow tabBar.
甚至UINavigationController的座位也会低于tabBar。
You could hide tabBar like this: 你可以像这样隐藏tabBar:
- (void)hideTabBar:(UITabBarController *)tabbarcontroller withInterval:(NSTimeInterval)delay {
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:delay];
for(UIView *view in tabbarcontroller.view.subviews)
{
if([view isKindOfClass:[UITabBar class]])
{
[view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y+50, view.frame.size.width, view.frame.size.height)];
}
else
{
[view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, view.frame.size.height+50)];
}
}
[UIView commitAnimations];
}
And then show it back on like this: 然后像这样展示回来:
- (void)showTabBar:(UITabBarController *)tabbarcontroller withInterval:(NSTimeInterval)delay {
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:delay];
for(UIView *view in tabbarcontroller.view.subviews)
{
if([view isKindOfClass:[UITabBar class]])
{
[view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y-50, view.frame.size.width, view.frame.size.height)];
}
else
{
[view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, view.frame.size.height-50)];
}
}
[UIView commitAnimations];
}
UITabBar is of height 50 px by default. UITabBar默认高度为50像素。 So you just need to set new height to the frame and animate it.
所以你只需要为框架设置新的高度并为其设置动画。
您可以将视图添加到主窗口,它将位于选项卡栏上:
[[myApp appDelegate].window addSubview:myView];
