Change the color of the UITabBarItem icon in iOS 7.1

Question

I can’t change the color of the UItabBarItem icon in iOS 7.1, so I just added UILabel to the TabBar and set the color I needed and got the job in iOS 7.1. But I'm not sure if this is the right way to do this. I will post my application to the appstore. Can someone direct me if there is a possibility that my application is rejected because of this? Below is my code.

UILabel *badge=[[UILabel alloc]init];
badge.text = @"2";
badge.textAlignment=NSTextAlignmentCenter;
badge.frame=CGRectMake(122, 1, 20, 20);
badge.layer.cornerRadius=10;
badge.textColor=[UIColor whiteColor];
badge.backgroundColor=[UIColor greenColor];
[tabbar addSubview:badge];

Answer 1

You cannot change the color of the icon because it was not open to the user. You can set only text as a string

@property(nonatomic,copy) NSString *badgeValue;    // default is nil

Whatever you do is all right.

            if view.isKindOfClass(PGTabBadge) {
                let badgeView = view as! PGTabBadge
                let index = badgeView.tag

                if badgeValues[index]==0 {

        for var i=0;i<labelExistsForIndex.count;i++ {
            if labelExistsForIndex[i] == false {

                    addBadge(i, value: badgeValues[i], color:UIColor(red: 4/255, green: 110/255, blue: 188/255, alpha: 1), font: UIFont(name: "Helvetica-Light", size: 11)!)
                }
            }
        }


    }

    func addBadge(index:Int,value:Int, color:UIColor, font:UIFont){

        let itemPosition = CGFloat(index+1)
        let itemWidth:CGFloat = tabBar.frame.width / CGFloat(tabBar.items!.count)

        let bgColor = color

        let xOffset:CGFloat = 12
        let yOffset:CGFloat = -9

        var badgeView = PGTabBadge()
        badgeView.frame.size=CGSizeMake(17, 17)
        badgeView.center=CGPointMake((itemWidth * itemPosition)-(itemWidth/2)+xOffset, 20+yOffset)
