Implementation of IOS Custom Tabbar

The implementation of the effect is probably like this, the picture is not good-looking, live to see

Just stick to the code.

1. First create a Singleview program

2. Change Viewcontroller base class to Uitabbarcontroller

3. Then write the. m file as follows [PS I'm open arc]

-  (void) viewdidload {    [super viewdidload];    //  Do any additional setup after loading the view, typically  from a nib.        [self initowncontrollers];     [self initowntabview];    [self.tabbar sethidden:yes];} /* * set multiple tabs, in order to toggle  **/-  (void) Initowncontrollers{    nsarray *array  = @[@ "Home", @ "more", @ "file", @ "info", @ "discover"];  //  each tab title          NSMutableArray *conArray = [[NSMutableArray alloc] init];         for  (Nsstring *object in array)  {  //   Traverse         uiviewcontroller *con = [[ uiviewcontroller alloc] init];        con.title = object;         //  set the navigation bar to show the title, which makes it easy to tell which page to switch to         uinavigationcontroller  *controll = [[UINavigationController alloc] initWithRootViewController:con];         [conArray addObject:controll];    }         self.viewcontrollers = conarray;} /* *  defines its own tabbar **/-  (void) initowntabview{    uiview *view  = [[uiview alloc] initwithframe:cgrectmake (5, 519, 310, 44)]; //  Use the latest xcode, coordinate a bit of a problem, adjust it yourself     view.backgroundColor = [UIColor whiteColor];     view.layer.cornerRadius = 9; //  set rounded corners, nice points          //  load each button's picture     nsarray *imagearray = @[@ "Home.png", @ "Much.png", @ "file.png", @ "Message.png", @ " Discover.png "];    for  (int index = 0; index < [ imagearray count]; index++)  {        uibutton * button = [uibutton buttonwithtype:uibuttontypesystem];         [button setimage:[uiimage imagenamed:imagearray[index]] forstate: Uicontrolstatenormal];        [button addtarget:self action: @selector (pagechanged:)  forControlEvents:UIControlEventTouchDown];         button.frame = cgrectmake (21+index*62, 7, 30, 30);  //  This coordinate should be set correctly                  button.tag = index;   //  set Tag  to conveniently set switch pages         [view addSubview:button];     }        [self.view addsubview:view];} -  (void) pagechanged: (uibutton *) button{    self.selectedindex =  button.tag;   //  the event handling of its own button}
