一.删除系统的标签栏上的按钮(tabbarItem)
//设置tabbar的背景
[self.tabBar setBackgroundImage:[UIImage p_w_picpathNamed:@"tab_bg_all.png"]];
//删除系统的tabbarItem
NSArray *array = self.tabBar.subviews;
//注意：UITabBarButton是一个私有的API，没有公开出来
//遍历tabbar中所有的子视图，并且移除tabbarItem
for (UIView *view in array) {
Class cls = NSClassFromString(@"UITabBarButton");
if ([view isKindOfClass: cls]) {
//移除tabbar上的按钮
[view removeFromSuperview];
}
}
//创建自己的图片
//创建选择视图
_selectedImgView = [[UIImageView alloc] initWithImage:[UIImage p_w_picpathNamed:@"selectTabbar_bg_all1"]];
_selectedImgView.frame = CGRectMake(0, 0, 49, 49);
[self.tabBar addSubview:_selectedImgView];
//创建按钮
NSArray *imgArr = @[@"movie_home.png",
@"msg_new.png",
@"start_top250.png",
@"icon_cinema.png",
@"more_setting.png"];
NSArray *titleArrray = @[@"电影", @"新闻", @"top", @"影院", @"更多"];
CGFloat width = kScreenWidth / imgArr.count;
CGFloat height = self.tabBar.height;
for (int i = 0; i < imgArr.count; i++) {
NSString *imgName = imgArr[i];
NSString *title = titleArrray[i];
MainTabbarItem *item = [[MainTabbarItem alloc] initWithFrame:CGRectMake(width * i, 0, width, height)
p_w_picpathName:imgName
title:title];
item.tag = 2015 + i;
[item addTarget:self action:@selector(clickItem:) forControlEvents:UIControlEventTouchUpInside];
[self.tabBar addSubview:item];
if (i == 0) {
_selectedImgView.center = item.center;
}
当push到二级界面时,隐藏标签栏
在自定义初始化方法中
self.hidesBottomBarWhenPushed = YES;
二,情况二,隐藏系统的标签栏,自定义标签栏
self.tabBar.hidden = YES;
_taBarView = [[UIImageView alloc]initWithFrame:CGRectMake(0, kScreenHeight-55, kScreenWidth, 55)];
当push到二级界面时,隐藏标签栏
#pragma mark - UINavigationControllerDelegate
//进入到二级界面以后隐藏标签栏(自定义的)
- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
//获取标签栏
MainTabBarViewController *mainBar = (MainTabBarViewController *)self.tabBarController;
//当前控制器的个数
NSInteger count = self.viewControllers.count;
if (count == 1) {
//显示标签栏
[UIView animateWithDuration:0.2 animations:^{
mainBar.taBarView.right = kScreenWidth;
}];
}else if (count == 2){
[UIView animateWithDuration:0.2 animations:^{
mainBar.taBarView.right = 0;
}];
}
}
