自定义UITabBarController

     最近发现一款和糗百差不多的应用叫<逗乐玩>,它的底部标签栏的效果不错,于是动手写了下,下面给出具体代码示例.

#pragma mark - 自定义UITabBar
- (void)createCustomTabBarView{
    
    _backGroundImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, ScreenHeight - tab_hight, ScreenWidth, tab_hight)];
    _backGroundImageView.image = [UIImage imageNamed:@"nav"];
    _backGroundImageView.userInteractionEnabled = YES;
    [self.view addSubview:_backGroundImageView];
    [_backGroundImageView release];
    
    _selectImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, -5, tabitem_width , tab_hight+5)];
    _selectImageView.image = [UIImage imageNamed:@"nav_btn"];
    [_backGroundImageView addSubview:_selectImageView];
    [_selectImageView release];
    
   #pragma mark first标签
    _nameLabel = [[UILabel alloc] initWithFrame:CGRectMake(27, 21, img_width, img_hight)];
    _nameLabel.text = @"段子";
    _nameLabel.font = [UIFont systemFontOfSize:12.0];
    _nameLabel.textColor = [UIColor whiteColor];
    _buttonImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"paper"] highlightedImage:[UIImage imageNamed:@"paperH"]];
    _buttonImageView.highlighted = YES;
    _buttonImageView.frame = CGRectMake(img_x, img_y, img_width, img_hight);
    _firstButton = [UIButton buttonWithType:UIButtonTypeCustom];
    _firstButton.frame = CGRectMake(tabitem_width * 0, other_offtop, tabitem_width, tabitem_hight);
    _firstButton.tag = 0 + TAG;
    [_firstButton addTarget:self action:@selector(didClickButtonAction:) forControlEvents:UIControlEventTouchUpInside];
    [_firstButton addSubview:_buttonImageView];
    [_firstButton addSubview:_nameLabel];
    [_buttonImageView release];
    [_nameLabel release];

    #pragma mark third标签
    _nameLabel = [[UILabel alloc] initWithFrame:CGRectMake(27, 21, img_width, img_hight)];
