iOS tabBar颜色渲染和改变选中时图片

创建以一个类继承UITabBarController
- (void)viewDidLoad {
[super
viewDidLoad];

//当tabBar图片被选中时，是自定义的颜色，而不是默认的蓝色
self.tabBar.tintColor = [UIColor
colorWithRed:0
green:0.5
blue:0
alpha:1];

//当tabBar某一item图片被选中时，是自定义的图片

UITabBarItem *item =
self.tabBar.items[0];
item.selectedImage = [UIImage
imageNamed:@"tab_funselected"];

item = self.tabBar.items[2];
item.selectedImage = [UIImage
imageNamed:@"tab_photoselected"];
}
