object-c 自定义Tabbar
自定义tabbar总会遇到各种问题,例如:
1.push,tabbar不会自动隐藏
2.tabbar背景图片上边缘有条灰色细线 等等
以下内容是创建一个controller继成UITabBarController

在viewdidload中,移除 self.tabBar.subviews(请注意这段代码),后自定义一个view进行覆盖,务必注意tabbar系统高度 49 像素,所以如果size不匹配会出现灰色线情况

在vi_tabbar 上加载各种控件,一般情况加载button,然后点击,根据button的tag值进行subcontroller的切换
self.selectedIndex = bu_now.tag;
至此,已经完成。
扩充:push时默认让tabbar隐藏,ios7以上支持手势滑动返回,如下代码
self.hidesBottomBarWhenPushed = YES;
NSMutableDictionary *ndic_current = [[NSMutableDictionary alloc]initWithDictionary:dic_data];
LB_JECP_CustomJewelry_DetailViewController *detail = [[LB_JECP_CustomJewelry_DetailViewController alloc]init];
detail.nDic_current = ndic_current;
detail.detailType = GoodsList;
[self.navigationController pushViewController:detail animated:YES];
[detail release];
self.hidesBottomBarWhenPushed = NO;
if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
self.navigationController.interactivePopGestureRecognizer.delegate = nil;
}
