Am newbie to ios and I found this solution on making the UINavigationBar Transparent. Where in my project files can I put this code
[self.navigationBar setBackgroundImage:[UIImage new]
forBarMetrics:UIBarMetricsDefault];
self.navigationBar.shadowImage = [UIImage new];
self.navigationBar.translucent = YES;
So that it is applied in my entire project where navigation controller is being used.
Put in your viewDidLoad
function of your rootViewController this code:
[self.navigationController.navigationBar setBackgroundImage:[UIImage new]
forBarMetrics:UIBarMetricsDefault];
self.navigationController.navigationBar.shadowImage = [UIImage new];
self.navigationController.navigationBar.translucent = YES;
self.navigationController.view.backgroundColor = [UIColor clearColor];
if let navigationBar = navigationController?.navigationBar {
navigationBar.setBackgroundImage(UIImage(), forBarMetrics: .Default)
navigationBar.shadowImage = UIImage()
navigationBar.translucent = true
navigationController?.view.backgroundColor = .clearColor()
}
if let navigationBar = navigationController?.navigationBar {
navigationBar.setBackgroundImage(UIImage(), for: .default)
navigationBar.shadowImage = UIImage()
navigationBar.isTranslucent = true
navigationController?.view?.backgroundColor = .clear
}
This works for sure! Transparent UINavigationBar .
If you want change the appearance for all your application, I recommend you to use this:
[[UINavigationBar appearance] setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault];
hope that will help
In your UIViewController class. You can also use UIAppearance mechanism http://nshipster.com/uiappearance/
And place this
[[UINavigationBar appearance] setBackgroundImage:[UIImage new]
forBarMetrics:UIBarMetricsDefault];
[UINavigationBar appearance].shadowImage = [UIImage imageNamed:@"Your image file here"];
into
- ( BOOL ) application:( UIApplication* ) application didFinishLaunchingWithOptions:( NSDictionary* ) launchOptions
Transparent UIToolbar:
self.toolbar.setBackgroundImage(UIImage(),
forToolbarPosition: UIBarPosition.Any,
barMetrics: UIBarMetrics.Default)
self.toolbar.setShadowImage(UIImage(),
forToolbarPosition: UIBarPosition.Any)
Transparent UINavigationBar:
self.navigationBar.setBackgroundImage(UIImage(), forBarMetrics: UIBarMetrics.Default)
self.navigationBar.shadowImage = UIImage()
self.navigationBar.translucent = true
设置以下代码
Self.navigationcontroller.navigationbar.transculant=yes;
