Question

I don’t know why I am getting this problem.

Details – I have a tab-bar controller in my application. On one tab I have a form which contains some buttons. I am setting up the titles of these buttons. Now, when I change tabs and come back to the same tab, all the button titles appear darken.

I am attaching screen-shots as well.

Any help would be appreciated.

Thank you !!

EDIT : Here is the code of how I am creating the buttons –

-(void)viewWillAppear:(BOOL)animated
{
    float yFrame =310.0f;
            for(int i =0;i<7;i++){

                openPickerButton=[UIButton buttonWithType:UIButtonTypeCustom];
                openPickerButton.frame = CGRectMake(29.0, yFrame+10.0, 280.0, 48.0);
                openPickerButton.tag=i;
                openPickerButton.backgroundColor=[UIColor clearColor];
                [openPickerButton setTitle:[formButtonTitle objectAtIndex:openPickerButton.tag] forState:UIControlStateNormal];

                openPickerButton.titleLabel.font=[UIFont fontWithName:@"Helvetica" size:16];
                [openPickerButton setTitleColor:[UIColor lightGrayColor] forState:UIControlStateNormal];
                openPickerButton.contentHorizontalAlignment=UIControlContentHorizontalAlignmentLeft;
                openPickerButton.showsTouchWhenHighlighted = YES;
                [openPickerButton addTarget:self action:@selector(PickChoreButtonAction:) forControlEvents:UIControlEventTouchUpInside];
                [setPreferencesFormScrollView addSubview:openPickerButton];
                yFrame+=60.0f;
            }
}

Well in viewDidLoad your objects get called once.(As soon as the view get loaded.
Stop)
In viewWillAppear they get called every time the view appears.

- (void)viewDidLoad
{
    [super viewDidLoad];
    float yFrame =310.0f;
            for(int i =0;i<7;i++){

                openPickerButton=[UIButton buttonWithType:UIButtonTypeCustom];
                openPickerButton.frame = CGRectMake(29.0, yFrame+10.0, 280.0, 48.0);
                openPickerButton.tag=i;
                openPickerButton.backgroundColor=[UIColor clearColor];
                [openPickerButton setTitle:[formButtonTitle objectAtIndex:openPickerButton.tag] forState:UIControlStateNormal];

                openPickerButton.titleLabel.font=[UIFont fontWithName:@"Helvetica" size:16];
                [openPickerButton setTitleColor:[UIColor lightGrayColor] forState:UIControlStateNormal];
                openPickerButton.contentHorizontalAlignment=UIControlContentHorizontalAlignmentLeft;
                openPickerButton.showsTouchWhenHighlighted = YES;
                [openPickerButton addTarget:self action:@selector(PickChoreButtonAction:) forControlEvents:UIControlEventTouchUpInside];
                [setPreferencesFormScrollView addSubview:openPickerButton];
                yFrame+=60.0f;
            }
}
