关于UITabBarController的设置（iOS 开发）

1.设置图片(选中以及未选中)

UITabBarItem *TuiJianItem=[[UITabBarItem alloc]initWithTitle:@"我的" image:[[UIImage imageNamed:@"index_bottom07_"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal] selectedImage:[[UIImage imageNamed:@"index_bottom08_"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];

2.设置选中状态字体颜色

[tabBarItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:

[UIFont fontWithName:@"Helvetica-Bold" size:10],

NSFontAttributeName,[UIColor colorWithRed:153/255.0 green:153/255.0 blue:153/255.0 alpha:1],NSForegroundColorAttributeName,

nil] forState:UIControlStateNormal];

3.常规设置

UITabBarController *tabBar=[[UITabBarController alloc]init];

[email protected][_homeNav,_erShouNav,_orderNav,_tuiJianNav];

tabBar.view.backgroundColor = [UIColor whiteColor];

tabBar.selectedIndex = 0;//默认展示页

tabBar.delegate=self;
