用系统的TabBar不让系统渲染图片设置文字背影颜色

AppDelegate

    self.window=[[UIWindowalloc]initWithFrame:[UIScreenmainScreen].bounds];

    self.window.backgroundColor=[UIColorwhiteColor];

    CustomTabBar * cus=[[CustomTabBaralloc]init];

  //  cus.tabBar.backgroundImage=[UIImage imageNamed:@"tabbar"];

    //设置tabbar文字背影色

    cus.tabBar.tintColor=[UIColorcolorWithRed:1.000green:0.399blue:0.028alpha:1.000];

    self.window.rootViewController=cus;

    [self.windowmakeKeyAndVisible];

    return YES;

自定义的tabBar类

#import "CustomTabBar.h"

#import "FirstViewController.h"

#import "SecondViewController.h"

#import "ThreeViewController.h"

#import "FourViewController.h"

@interface CustomTabBar ()
