I want to convert my current project from iOS 6 to iOS 7. In iOS 6 my project is working fine, but in iOS 7 navigation bar image is not showing properly.
I used this code snippet for iOS 6,
UIImage *imgNav = [UIImage imageNamed:@"navigation.png"];
self.navigationController.navigationBar.frame = CGRectMake(0, 0, 320, 44);
[self.navigationController.navigationBar setBackgroundImage:imgNav forBarMetrics:
UIBarMetricsDefault];
How can I set the navigation bar image in iOS 7?
Try Adding the below code in AppDelegate
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"navigation.png"]
forBarMetrics:UIBarMetricsDefault];
This is the Swift Version:
UINavigationBar.appearance().setBackgroundImage(UIImage.init(named: "navigation.png"), forBarMetrics: UIBarMetrics.Default)
Swift 3 version :
UINavigationBar.appearance().setBackgroundImage(UIImage.init(named: "logo-dark.png"), for: UIBarMetrics.default)
对于iOS 7:
[self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@"navbar.png"] forBarMetrics:UIBarMetricsDefault];
Use This Simple Syntax for Change Navigation Background
Easy Way.
self.navigationController.navigationBar.barTintColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"YourImage.png"]];
self.navigationController.navigationBar.titleTextAttributes = @{NSForegroundColorAttributeName: [UIColor whiteColor]};
if ([self.navigationController.navigationBar respondsToSelector:@selector(setBackgroundImage:forBarMetrics:)] )
{
UIImage *image = [UIImage imageNamed:@"navigation.png"];
[self.navigationController.navigationBar setBackgroundImage:image forBarMetrics:UIBarMetricsDefault];
}
The Storyboard Way:
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"navigation.png"] forBarMetrics:UIBarMetricsDefault];
Its working if you follow the rules mentioned in ios7 guide: • If you want a solid color with no gradient, create a 1 x 1 point image. • If you want a vertical gradient, create an image that has a width of 1 point and a height that matches the height of the UI element's background. • If you want to provide a repeating textured appearance, you need to create an image with dimensions that match the dimensions of the repeating portion of the texture. • If you want to provide a nonrepeating textured appearance, you need to create a static image with dimensions that match the dimensions of the UI element's background area.

Just do this..
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// This will set the backGround image for all the Navigation Bars
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"navigationBar"] forBarMetrics:UIBarMetricsDefault];
return YES;
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[[UINavigationBar appearance] setTitleTextAttributes: @{
UITextAttributeTextColor: [UIColor whiteColor],
UITextAttributeTextShadowColor: [UIColor clearColor],
UITextAttributeTextShadowOffset: [NSValue valueWithUIOffset:UIOffsetMake(0.0f, 1.0f)],
UITextAttributeFont: [UIFont fontWithName:@"AppleGothic" size:20.0f]
}];
if([[[UIDevice currentDevice] systemVersion] floatValue] < 7.0)
{
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"navigatio_for_ios6"] forBarMetrics:UIBarMetricsDefault];
[[UINavigationBar appearance] setTitleVerticalPositionAdjustment:0.0 forBarMetrics:UIBarMetricsDefault];
}
else
{
[[UINavigationBar appearance] setBarTintColor:UIColorFromRGB(0x067AB5)];
// Uncomment to change the color of back button
[[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];
// Uncomment to assign a custom backgroung image
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"navigon_bg_ios7.png"] forBarMetrics:UIBarMetricsDefault];
// Uncomment to change the back indicator image
[[UINavigationBar appearance] setBackgroundColor:[UIColor whiteColor]];
[[UINavigationBar appearance] setBackIndicatorTransitionMaskImage:[UIImage imageNamed:@""]];
// Uncomment to change the font style of the title
NSShadow *shadow = [[NSShadow alloc] init];
shadow.shadowColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8];
shadow.shadowOffset = CGSizeMake(0, 1);
[[UINavigationBar appearance] setTitleTextAttributes: [NSDictionary dictionaryWithObjectsAndKeys:[UIColor colorWithRed:245.0/255.0 green:245.0/255.0 blue:245.0/255.0 alpha:1.0], NSForegroundColorAttributeName,shadow, NSShadowAttributeName,[UIFont fontWithName:@"HelveticaNeue-Bold" size:18.0], NSFontAttributeName, nil]];
[[UINavigationBar appearance] setTitleVerticalPositionAdjustment:0.0 forBarMetrics:UIBarMetricsDefault];
}
}
在appDelegate类中试用这段代码它会对你有所帮助。
[[UINavigationBar appearance] setBackgroundImage:[[UIImage imageNamed:@"navbarimg.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)] forBarMetrics:UIBarMetricsDefault];
