UISegmentedControl only changes text color when revisiting ViewController

UPDATE ANSWERED. BY ME.

Currently having problems with the text color change of my UISegmentedControl; it needs to change on first load with UIControlStateSelected. Code works, but only conditionally. It works when you visit the page with the segmented control on the navigation bar, hit the back button, and then visit the page again. I'm assuming there's a problem with inheritance here. Let me explain..

The location of the the segmented control lies on top of my navigation bar.

Inheritance of the ViewController which contains the SegmentedControl: TabBarViewController(managed with AppDelegate)-->navigation Controller-->ViewController(where 'inviteSegBar' lies)

Here's the code within AppDelegate.m:

[[UINavigationBar appearance] setBarTintColor:[UIColor colorWithHexString:@"#669900"]];//this one sets it green.
[[UINavigationBar appearance] setBackgroundColor:[UIColor whiteColor]];

And here's the viewDidLoad: code for the VC which contains 'inviteSegBar', the UISegmentedControl in question:

- (void)viewDidLoad
{
    [super viewDidLoad];

    //CUSTOM APPEARANCE <below>
    self.navigationController.navigationBar.barTintColor = [UIColor whiteColor];
    self.navigationController.navigationBar.tintColor = [UIColor colorWithHexString:@"#669900"];

    inviteSegBar.tintColor = [UIColor colorWithHexString:@"#333333"];

    [[UISegmentedControl appearance] setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor colorWithHexString:@"#669900"]} forState:UIControlStateSelected];
}

Like I said the last line works, but only when you re-visit the page. Why is this happening?

PS This is the same issue guys, I had already tried this code before any of the answers were listed.

Use

UIColor *whitecolor = [UIColor whiteColor];
NSDictionary *attributes = [NSDictionary dictionaryWithObjects:@[whitecolor] forKeys:@[UITextAttributeTextColor]];
[yourSegment setTitleTextAttributes:attributes
                                         forState:UIControlStateNormal];

UIColor *grayColor = [UIColor darkGrayColor];
NSDictionary *attributes = [NSDictionary dictionaryWithObjects:@[grayColor] forKeys:@[UITextAttributeTextColor]];
[yourSegment setTitleTextAttributes:attributes
                                         forState:UIControlStateSelected];

update

UIColor *whitecolor = [UIColor whiteColor];
    NSDictionary *attributes = [NSDictionary dictionaryWithObjects:@[whitecolor] forKeys:@[NSForegroundColorAttributeName]];
    [yourSegment setTitleTextAttributes:attributes
                                             forState:UIControlStateNormal];

    UIColor *grayColor = [UIColor darkGrayColor];
    NSDictionary *attributes = [NSDictionary dictionaryWithObjects:@[grayColor] forKeys:@[NSForegroundColorAttributeName]];
    [yourSegment setTitleTextAttributes:attributes
                                             forState:UIControlStateSelected];

For change UISegmentedControl appearance insert for example into viewDidLoad function this code:

// color selected text ---> red
[[UISegmentedControl appearance] setTitleTextAttributes:@{ NSForegroundColorAttributeName : [UIColor redColor] } forState:UIControlStateSelected];

// color disabled text ---> blue
[[UISegmentedControl appearance] setTitleTextAttributes:@{ NSForegroundColorAttributeName : [UIColor blueColor] } forState:UIControlStateNormal];

// color tint segmented control ---> black
[[UISegmentedControl appearance] setTintColor:[UIColor greenColor]];

This may help you:

UIAppearance proxy to set title text attributes but preserve tintColor for borders. 

[[UISegmentedControl appearance] setTitleTextAttributes:@{ 
NSForegroundColorAttributeName : [UIColor redColor] 
} forState:UIControlStateNormal];

This code allows you to set some text attributes for label in segmented control:

NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:
                            [UIColor blackColor], UITextAttributeTextColor,
                            nil];
[_segmentedControl setTitleTextAttributes:attributes forState:UIControlStateSelected];

More allowed attributes in Apple documentation: link
