iOS7 - Change UINavigationBar border color

Question

Is it possible to change the grey border-bottom color of the UINavigationBar in iOS7?

I already tried to remove to border, but this is not working:

[[UINavigationBar appearance] setShadowImage:[[UIImage alloc] init]];

Thanks!

Solution 1

This will help you :)

[self.navigationController.navigationBar.layer setBorderWidth:2.0];// Just to make sure its working
[self.navigationController.navigationBar.layer setBorderColor:[[UIColor redColor] CGColor]];

Solution 2

You are removing the shadow but not the border, you need to do the following:

[[UINavigationBar appearance] setBackgroundImage:[[UIImage alloc] init] forBarMetrics:UIBarMetricsDefault];
[[UINavigationBar appearance] setShadowImage:[[UIImage alloc] init]];

To change the border use an image of 2 pixels width line:

[[UINavigationBar appearance] setShadowImage:[UIImage imageNamed:@"2pxWidthLineImage"]];

Here is a category to change bottom color with height:

[self.navigationController.navigationBar setBottomBorderColor:[UIColor redColor] height:1];

Objective C:

UINavigationBar+Helper.h

#import <UIKit/UIKit.h>

@interface UINavigationBar (Helper)
- (void)setBottomBorderColor:(UIColor *)color height:(CGFloat)height;
@end

UINavigationBar+Helper.m

#import "UINavigationBar+Helper.h"

@implementation UINavigationBar (Helper)

- (void)setBottomBorderColor:(UIColor *)color height:(CGFloat)height {
    CGRect bottomBorderRect = CGRectMake(0, CGRectGetHeight(self.frame), CGRectGetWidth(self.frame), height);
    UIView *bottomBorder = [[UIView alloc] initWithFrame:bottomBorderRect];
    [bottomBorder setBackgroundColor:color];
    [self addSubview:bottomBorder];
}
@end

Swift:

extension UINavigationBar {

    func setBottomBorderColor(color: UIColor, height: CGFloat) {
        let bottomBorderRect = CGRect(x: 0, y: frame.height, width: frame.width, height: height)
        let bottomBorderView = UIView(frame: bottomBorderRect)
        bottomBorderView.backgroundColor = color
        addSubview(bottomBorderView)
    }
}

Here is another way:

CALayer *border = [CALayer layer];
border.borderColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"border"]].CGColor;
border.borderWidth = 1;
CALayer *layer = self.navigationController.navigationBar.layer;
border.frame = CGRectMake(0, layer.bounds.size.height, layer.bounds.size.width, 1);
[layer addSublayer:border];

The only way I found to change color is:

override func viewDidLoad() {
    super.viewDidLoad()

    if let navigationController = self.navigationController {
        let navigationBar = navigationController.navigationBar
        let navigationSeparator = UIView(frame: CGRectMake(0, navigationBar.frame.size.height - 1, navigationBar.frame.size.width, 0.5))
        navigationSeparator.backgroundColor = UIColor.redColor() // Here your custom color
        navigationSeparator.opaque = true
        self.navigationController?.navigationBar.addSubview(navigationSeparator)
    }

}
