    UIViewController* vc = [_tabBarController.viewControllers objectAtIndex: 0];
    vc.tabBarItem = [[UITabBarItem alloc] initWithTitle: @"title" image:[UIImage imageNamed:@"home.png"] tag:0];

}

Answer 1

//this code for when you select tabbar item tab.

vc.tabBarItem1.selectedImage = [[UIImage imageNamed:@"selectimg"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];

//this code for default image of tabar item tab.

 vc.tabBarItem.image = [[UIImage imageNamed:@"deselectimg"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];

//this code for title of your tabar item tab.

vc.tabBarItem.title = @"xxxx";

Answer 2

使用此代码在选择和取消选择中设置图像，

[tabBarItem1 setFinishedSelectedImage:[UIImage imageNamed:@"homeSelect.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"homeUnSelect.png"]];
