Change the color of selected segment control

Question

In my app,i able to change the color of the selected segment control.But the color is changed for another index rather than selected index. I can find any mistake in the index.

Help me!

my code is as follow:

if([SegmentRound selectedSegmentIndex] == 0)
    {

        UIColor *newSelectedTintColor2 = [UIColor colorWithRed: 98/255.0 green:156/255.0 blue:247/255.0 alpha:1.0];
        [[[SegmentRound subviews] objectAtIndex:0] setTintColor:newSelectedTintColor2];

        UIColor *newSelectedTintColor1 = [UIColor colorWithRed: 54/255.0 green:52/255.0 blue:48/255.0 alpha:1.0];
        [[[SegmentRound subviews] objectAtIndex:1] setTintColor:newSelectedTintColor1];

        UIColor *newSelectedTintColor0 = [UIColor colorWithRed: 54/255.0 green:52/255.0 blue:48/255.0 alpha:1.0];
        [[[SegmentRound subviews] objectAtIndex:2] setTintColor:newSelectedTintColor0];



        FLAGROUND=1;
    }

    if([SegmentRound selectedSegmentIndex] == 1)
    {
        UIColor *newSelectedTintColor1 = [UIColor colorWithRed: 98/255.0 green:156/255.0 blue:247/255.0 alpha:1.0];
        [[[SegmentRound subviews] objectAtIndex:1] setTintColor:newSelectedTintColor1];

        UIColor *newSelectedTintColor0 = [UIColor colorWithRed: 54/255.0 green:52/255.0 blue:48/255.0 alpha:1.0];
        [[[SegmentRound subviews] objectAtIndex:0] setTintColor:newSelectedTintColor0];

        UIColor *newSelectedTintColor2 = [UIColor colorWithRed: 54/255.0 green:52/255.0 blue:48/255.0 alpha:1.0];
        [[[SegmentRound subviews] objectAtIndex:2] setTintColor:newSelectedTintColor2];

        FLAGROUND=2;
    }
    if([SegmentRound selectedSegmentIndex] == 2)
    {
        UIColor *newSelectedTintColor0 = [UIColor colorWithRed: 98/255.0 green:156/255.0 blue:247/255.0 alpha:1.0];
        [[[SegmentRound subviews] objectAtIndex:2] setTintColor:newSelectedTintColor0];

        UIColor *newSelectedTintColor2 = [UIColor colorWithRed: 54/255.0 green:52/255.0 blue:48/255.0 alpha:1.0];
        [[[SegmentRound subviews] objectAtIndex:0] setTintColor:newSelectedTintColor2];

        UIColor *newSelectedTintColor1 = [UIColor colorWithRed: 54/255.0 green:52/255.0 blue:48/255.0 alpha:1.0];
        [[[SegmentRound subviews] objectAtIndex:1] setTintColor:newSelectedTintColor1];
        FLAGROUND=3;
    }

viewwillAppear:

[SegmentRound setSelectedSegmentIndex:0];

you can directly apply color in nib fil. why you manage through coding? — Hiren, Aug 24 '12 at 06:18

I'd recommend to create the two colors outside of your condition, makes your code a bit smaller. Then you can use a foreach to iterate over your segments :

UIColor *selectedColor = [UIColor colorWithRed: 98/255.0 green:156/255.0 blue:247/255.0 alpha:1.0];
UIColor *deselectedColor = [UIColor colorWithRed: 54/255.0 green:52/255.0 blue:48/255.0 alpha:1.0];

for (UIControl *subview in [SegmentRound subviews]) {
    if ([subview isSelected]) 
       [subview setTintColor:selectedColor]; 
    else
       [subview setTintColor:deselectedColor]; 
}

check out this one

-(IBAction)segmentBtnPressed:(UISegmentedControl*)sender{
for (int i=0; i<[sender.subviews count]; i++) 
{
    if ([[sender.subviews objectAtIndex:i]isSelected] ) 
    {               
    UIColor *tintcolor=[UIColor colorWithRed: 98/255.0 green:156/255.0 blue:247/255.0 alpha:1.0];
    [[sender.subviews objectAtIndex:i] setTintColor:tintcolor];
    }
    else{
     UIColor *tintcolor=[UIColor colorWithRed:127.0/255.0 green:161.0/255.0 blue:183.0/255.0 alpha:1.0];
    [[sender.subviews objectAtIndex:i] setTintColor:tintcolor];

    }
}
}

I hope you can simply change the TintColor of Segment Control. It works perfectly for me.

I tried printing subviews of segment control on console and I detected that indexes are in reverse order, means if selectedSegment is 0 then your subview should be 2 not 0.Try printing segment control on console and you will see the same result as follows on segment action.:

NSArray *theArr = [mSegmentedControl subviews];
            DEBUGLOG(@"controls arr: %@",theArr);

Logs on console:

controls arr: (
    "<UISegment: 0x8598ad0; frame = (77 0; 76 34); opaque = NO; layer = <CALayer: 0x8598b30>>",
    "<UISegment: 0x85986e0; frame = (0 0; 76 34); opaque = NO; layer = <CALayer: 0x8598740>>"
)

Change the color of selected segment control
