+ (void)initialize
{
    //the color for the text for unSELEcted tabs
    [UITabBarItem.appearance settitleTextAttributes:@{NSForegroundColorAttributename : [UIColor redColor]} forState:UIControlStateNormal];

    //the color for SELEcted icon
    [[UITabBar appearance] setSELEctedImageTintColor:[UIColor whiteColor]];    
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {
        for (UITabBarItem *tbi in self.tabBar.items) {
            tbi.image = [tbi.image imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
        }
    }
}

如果您创建项目手册,您必须在每个图标上设置UIImageRenderingModeAlwaysOriginal,并从初始化中添加代码.@H_301_8@
