iOS跳转界面时隐藏tabBar的方法

//1.设置self.tabBarController.tabBar.hidden=YES;
     
    self.tabBarController.tabBar.hidden=YES;
 
//2.如果在push跳转时需要隐藏tabBar，设置self.hidesBottomBarWhenPushed=YES;
 
    self.hidesBottomBarWhenPushed=YES;
    NextViewController *next=[[NextViewController alloc]init];
    [self.navigationController pushViewController:next animated:YES];
    self.hidesBottomBarWhenPushed=NO;
 
//并在push后设置self.hidesBottomBarWhenPushed=NO;
//这样back回来的时候，tabBar会恢复正常显示。

Iphone隐藏和显示TabBar的方法
1.隐藏TabBar：

- (void)hideTabBar {  
    if (self.tabBarController.tabBar.hidden == YES) {  
        return;  
    }  
    UIView *contentView;  
    if ( [[self.tabBarController.view.subviews objectAtIndex:0] isKindOfClass:[UITabBar class]] )  
        contentView = [self.tabBarController.view.subviews objectAtIndex:1];  
    else  
        contentView = [self.tabBarController.view.subviews objectAtIndex:0];  
    contentView.frame = CGRectMake(contentView.bounds.origin.x,  contentView.bounds.origin.y,  contentView.bounds.size.width, contentView.bounds.size.height + self.tabBarController.tabBar.frame.size.height);          
    self.tabBarController.tabBar.hidden = YES;  
      
}  

2.显示TabBar：

- (void)showTabBar  
  
{  
    if (self.tabBarController.tabBar.hidden == NO)  
    {  
        return;  
    }  
    UIView *contentView;  
    if ([[self.tabBarController.view.subviews objectAtIndex:0] isKindOfClass:[UITabBar class]])  
          
        contentView = [self.tabBarController.view.subviews objectAtIndex:1];  
  
    else  
          
        contentView = [self.tabBarController.view.subviews objectAtIndex:0];        
    contentView.frame = CGRectMake(contentView.bounds.origin.x, contentView.bounds.origin.y,  contentView.bounds.size.width, contentView.bounds.size.height - self.tabBarController.tabBar.frame.size.height);  
    self.tabBarController.tabBar.hidden = NO;  
      
}  

3.如果定义了上面两个方法，在viewDidAppear:方法里面就可以调用了

-(void)viewDidAppear:(BOOL)animated{  
    //[self hideTabBar];  
    [self showTabBar];  
}

iOS隐藏tabBar的方法

两种方法用来隐藏tabBar
1.在本页面隐藏
#pragma mark - 隐藏tabBar
- (void)viewWillAppear:(BOOL)animated{
   ** self.tabBarController.tabBar.hidden = YES;**
}
- (void)viewWillDisappear:(BOOL)animated{
**  self.tabBarController.tabBar.hidden = NO;**
}
2.再跳界面之前设置跳转后隐藏tabBar
#pragma mark - 隐藏tabBar
- (void)handleClickTestButtonAction:(UIButton *)sender{
    SecurityTestingViewController *test = [[SecurityTestingViewController alloc]init];
    **self.hidesBottomBarWhenPushed = YES;**
    [self.navigationController pushViewController:test animated:NO];
}

隐藏TabBar的一些方法小结

//在项目中经常遇到隐藏tabBar,实力很多种方法，可以解决不同情况下问题
//1：//隐藏tabBar
    WebViewController *webVc = [[WebViewController alloc] init];
    webVc.hidesBottomBarWhenPushed = YES;
    [self.navigationController pushViewController:webVc animated:YES];
    webVc.hidesBottomBarWhenPushed = NO;
    [webVc release];
//2.系统方法
    self.hidesBottomBarWhenPushed = YES;
//3:自定义tabBar时候，由tabBarController管理的
//隐藏tabBar
- (void) hideTabBar:(BOOL) hidden{
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0];
    for(UIView *view in self.tabBarController.view.subviews)    {
        if ([view isKindOfClass:[UITabBar class]]) {
            if (hidden) {
                [view setFrame:CGRectMake(view.frame.origin.x, iphone5?568:480, view.frame.size.width, view.frame.size.height)];
            } else {
                [view setFrame:CGRectMake(view.frame.origin.x, iphone5?568-49:480-49, view.frame.size.width, view.frame.size.height)];
            }
        } else {
            if (hidden) {
                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, iphone5?568:480)];
            } else {
                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width,  iphone5?568-49:480-49)];
            }
        }
    }
    [UIView commitAnimations];
}
//调整子视图
for (UIView *subView in self.view.subviews) {
    if ([subView isKindOfClass:NSClassFromString(@"UITransitionView")]) {
//        调整子视图的高度，UITransitionView视图为UINavitaionController的根视图
        subView.frame = CGRectMake(subView.frame.origin.x, subView.frame.origin.y, subView.frame.size.width, 480);
        CGRect frame = subView.frame;
        frame.size.height = 480;
        subView.frame = frame;
    }
}
//4：类似方法3
- (void)makeTabBarHidden:(BOOL)hide{
    if ([self.tabBarController.view.subviews count] < 2)    {
        return;
    }
    UIView *contentView;
    if ([[self.tabBarController.view.subviews objectAtIndex:0] isKindOfClass:[UITabBar class]])
    {
        contentView = [self.tabBarController.view.subviews objectAtIndex:1];
    }
    else
    {
        contentView = [self.tabBarController.view.subviews objectAtIndex:0];
    }
    //    [UIView beginAnimations:@"TabbarHide" context:nil];
    if (hide) {
        contentView.frame = self.tabBarController.view.bounds;
    }
    else
    {
        contentView.frame = CGRectMake(self.tabBarController.view.bounds.origin.x,
                                       self.tabBarController.view.bounds.origin.y,
                                       self.tabBarController.view.bounds.size.width,
                                       self.tabBarController.view.bounds.size.height - self.tabBarController.tabBar.frame.size.height);
    }       
    self.tabBarController.tabBar.hidden = hide;
}
