隐藏tabBar和navigationbar

Posted on May 30, 2015 By anchoriteFili

隐藏tabbar有两种方式

1：在pushViewController之前调用
[self setHidesBottomBarWhenPushed:YES];

同时在viewWillDisappear调用：

- (void)viewWillDisappear:(BOOL)animated {  
    [self setHidesBottomBarWhenPushed:NO];  
    [super viewDidDisappear:animated];  
}
2：使用函数：
- (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, 480, view.frame.size.width, view.frame.size.height)];  
            } else {  
                [view setFrame:CGRectMake(view.frame.origin.x, 433, 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, 480)];  
            } else {  
                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 433)];  
            }  
        }  
    }  
    [UIView commitAnimations];  
}

方式一的方法代码简单，且界面也好控制一些

如何隐藏UINavigationBar

显示：

[self.navigationController setNavigationBarHidden:NO animated:YES];

隐藏：

[self.navigationController setNavigationBarHidden:YES animated:YES];

隐藏返回键

self.navigationItem.hidesBackButton = YES;
