IOS custom UITabBar

You can use hidesBottomBarWhenPushed to hide a page.

Step 1: We need some images:

The icons of each option and the background image of tabbar are also a transparent 1x1 pixel image.

Step 2: Create a project and create a class in the project that inherits from UITabBarController.

Step 3: first write a method and return a UINavigationController

-(UINavigationController*) viewControllerWithTitle:(NSString*) title image:(UIImage*)image{    UIViewController* viewController = [[UIViewController alloc] init];    viewController.tabBarItem = [[UITabBarItem alloc] initWithTitle:title image:image tag:0];    viewController.title = title;    UINavigationController *nav = [[UINavigationController alloc]initWithRootViewController:viewController];    return nav;}

Then, create viewControllers of TabbarController in viewDidLoad.

 self.viewControllers = [NSArray arrayWithObjects:                            [self viewControllerWithTitle:@"1" image:IMG(@"1")],                            [self viewControllerWithTitle:@"2" image:IMG(@"2")],                            [self viewControllerWithTitle:nil image:nil],                            [self viewControllerWithTitle:@"3" image:IMG(@"3")],                            [self viewControllerWithTitle:@"4" image:IMG(@"4")], nil];

No. The third ViewController is not set.

Because we need to put a button at that position and continue to write in viewDidLoad:

    UIButton* button = [[UIButton alloc]initWithFrame:CGRectMake(0.0, 0.0, 65, 65)];    button.center = CGPointMake(160, 20);    [button setBackgroundImage:IMG(@"add") forState:UIControlStateNormal];    [button addTarget:self action:@selector(add:) forControlEvents:UIControlEventTouchUpInside];    [self.tabBar addSubview:button];

Then set the background image:

    [self.tabBar setBackgroundImage:IMG(@"tabbarbg")];

After running:

You will find that there is a horizontal line on the button, and then set this shadow to run, no one will find you wretched behavior.

    [self.tabBar setShadowImage:IMG(@"transparent")];

Finally (iOS7 and iOS6 ):
