Gradient not showing – only the second color

[bahlo]

I set the class CRGradientNavigationBar to the NavigationBar in my Storyboard.

Then in my custom UINavigationController class I do this in the viewDidLoad:

UIColor *firstColor = [UIColor colorWithRed:0/255.0f green:0/255.0f blue:255/255.0f alpha:1.0f];
UIColor *secondColor = [UIColor colorWithRed:255.0f/255.0f green:90.0f/255.0f blue:58.0f/255.0f alpha:1.0f];
NSArray *colors = [NSArray arrayWithObjects:firstColor, secondColor, nil];
[[CRGradientNavigationBar appearance] setBarTintGradientColors:colors];
[self.navigationBar setTranslucent:NO];

The bar changes it's color, but only to the second one provided.

Thanks in advance.

I assume you are using an IBOutlet, the code should be something like this:

#import "ViewController.h"
#import "CRGradientNavigationBar.h"

@interface ViewController ()

@property (nonatomic, weak) IBOutlet CRGradientNavigationBar *navigationBar;

@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];

    NSArray *colors = [NSArray arrayWithObjects:(id)[UIColor redColor].CGColor, (id)[UIColor orangeColor].CGColor, nil];

    [self.navigationBar setBarTintGradientColors:colors];

}

Thanks for your answer.

I'm not using an IBOutlet, I'm extending UINavigationController, so self.navigationBar already exists and already has the class CRGradientNavigationBar (via Storyboard).

I have recently started from scratch with code-only and have exactly the same problem. I copy-pasted the full example from the README and it only takes the second color (same problem). And I tried different View- and NavigationControllers but no changes.

Maybe a few words about my environment help:

• iPad App
• Landscape only
• iOS 7.1 (doesn't work with 7.0, either)

When I NSLog the navigationController.navigationBar, I get this output:

<CRGradientNavigationBar: 0x10972eab0; baseClass = UINavigationBar; frame = (-512 0; 1024 44); autoresize = W; gestureRecognizers = <NSArray: 0x109732c00>; layer = <CALayer: 0x10972e970>>

The thing, that I find really strange is: On any iPhone app it just works (and looks great, btw.).

Sorry, I didn't have enough time to replicate this bug, I'll look into it, I promise. :)

Your last comment did not age well, haha. Closing since it's no longer an issue for me.
