Changing the UINavigationBar background image
Considering all iOS versions, this seems to be accomplishing both Custom background image and Custom size of UINavigationBar:
@interface CustomNavigationBar : UINavigationBar
@end
@implementation CustomNavigationBar
-(void) drawRect:(CGRect)rect
{
UIImage *image = [UIImage imageNamed: @"navigationBar"];
[image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
//for iOS5
[self setBackgroundImage:[UIImage imageNamed: @"navigationBar"] forBarMetrics:UIBarMetricsDefault];
}
//for custom size of the UINavigationBar
- (CGSize)sizeThatFits:(CGSize)size {
CGSize newSize = CGSizeMake(320,31);
return newSize;
}
@end
I use such codes in a common place like a Utilities file.
Hope this helps.
Starting in iOS 5 you should use the -setBackgroundImage:forBarMetrics:
method:
[myNavbar setBackgroundImage:[UIImage imageNamed: @"UINavigationBarBackground.png"]
forBarMetrics:UIBarMetricsDefault];
And in Swift 4:
navigationBar.setBackgroundImage(UIImage(named: "UINavigationBarBackground.png"),
for: .default)
Just try with this code.. In your implmentation (.m) file.
#import "RootViewController.h"
@implementation UINavigationBar (CustomImage)
- (void)drawRect:(CGRect)rect {
UIImage *image = [UIImage imageNamed: @"navheader.png"];
[image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
}
@end
@implementation RootViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem;
self.title=@"You are Done.";
}
This has worked in excellent way for me.
Above Code Worked for only IOS 4. if you use the IOS 5 then use.....
[myNavbar setBackgroundImage:[UIImage imageNamed:
@"UINavigationBarBackground.png"]
forBarMetrics:UIBarMetricsDefault];
