My profile view controller is embedded inside the Navigation controller and it shows up with coloured navigation bar. But I want to avoid that or how to make navigation bar background color to clearColor. So that it can show the images below it eg. Twitter app
Try this code:
[self.navigationBar setBackgroundImage:[UIImage new]
forBarMetrics:UIBarMetricsDefault];
self.navigationBar.shadowImage = [UIImage new];
self.navigationBar.translucent = YES;
self.navigationController.navigationBar.tintColor = [UIColor clearColor];
self.navigationController.navigationBar.backgroundColor = [UIColor clearColor];
try this
[self.navigationBar setBackgroundImage:[UIImage new]
forBarMetrics:UIBarMetricsDefault];
self.navigationBar.shadowImage = [UIImage new];
self.navigationBar.translucent = YES;
in swift
self.navigationBar.setBackgroundImage(UIImage(), forBarMetrics: UIBarMetrics.Default)
self.navigationBar.shadowImage = UIImage()
self.navigationBar.translucent = true
It is very sample,
You can try:
YourNavigation.navigationBar.barTintColor = [UIColor clearColor];
YourNavigation: Enter your NavigationController.
If this can help, you can mark for me!
Thanks
Put this line in AppDelegate's didFinsihLaunchingWithOptions:
[[UINavigationBar appearance] setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault]; // This is for clear navigation bar
[[UINavigationBar appearance] setShadowImage:[UIImage new]]; // this for remvove line under the navigationbar
[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];
self.navigationController.navigationBar.backgroundColor = [UIColor clearColor];
You can't make navigation bar as clear . Just add you custom view then make it clear.

I want to make my NavigationbarClear color. So I tried like this in my ViewDidLoad
self.navigationController.navigationBar.hidden=NO;
[self.navigationController.navigationBar setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault];
self.navigationController.navigationBar.shadowImage=[UIImage new];
self.navigationController.navigationBar.translucent=YES;
self.navigationController.navigationBar.topItem.titleView.tintColor=[UIColor blackColor];
self.navigationController.navigationBar.topItem.title=[lan GetConvertedLanguageString:#"My Profile"];
self.navigationController.navigationBar.titleTextAttributes = [NSDictionary dictionaryWithObject:[UIColor whiteColor] forKey:NSForegroundColorAttributeName];
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"backarrow"] style:UIBarButtonItemStylePlain target:self action:#selector(revealToggle :)];
[self.navigationController navigationBar].tintColor = [UIColor whiteColor];
But nothing visible in my view controller. Whats wrong with this code? Please help me.
Thanks
Pick up navigation controller scene and then pickup navigationbar (see in pic) after that set the clear color from showutilites>attribute insepecter also you can change title color from here
Screenshot
Code
[self.navigationController.navigationBar setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault];
self.navigationController.navigationBar.shadowImage=[UIImage new];
self.navigationItem.title = #"1234";
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"Left" style:UIBarButtonItemStylePlain target:nil action:nil];
self.navigationController.navigationBar.titleTextAttributes = [NSDictionary dictionaryWithObject:[UIColor whiteColor] forKey:NSForegroundColorAttributeName];
[self.navigationController navigationBar].tintColor = [UIColor whiteColor];
So,I guess,your background of View is White,so you cannot see white text.
Note
navigationBar.titleTextAttributes
Display attributes for the bar’s title text.
navigationBar.tintColor
The tint color to apply to the navigation items and bar button items.
I made my UINavigationBar transparent in ViewDidLoad() using below code and
[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];
This is working perfectly and i want to remove this transparency and get back old (normal ) UINavigationBar on ViewDidDisappear( ).
How do I get normal UINavigationBar ?
Write the below line in your code:
[self.navigationController.navigationBar setTranslucent:NO]
And remove below code
self.navigationController.navigationBar.shadowImage = [UIImage new];
self.navigationController.view.backgroundColor = [UIColor clearColor];
I have followed the top guides on how to make my top bar transparent, but the best I can get is translucent. I am also trying to get the buttons white, not default blue. What am I missing?
#implementation FindAssetLocationMapViewController
- (void) viewWillAppear:(BOOL)animated {
self.edgesForExtendedLayout = UIRectEdgeAll;
self.extendedLayoutIncludesOpaqueBars = true;
[self.navigationController.navigationBar setTranslucent:YES];
self.navigationController.navigationBar.shadowImage = [UIImage new];
[self.navigationController.navigationBar setBackgroundImage:[[UIImage alloc] init] forBarMetrics:UIBarMetricsDefault];
self.navigationController.navigationBar.shadowImage = [[UIImage alloc] init];
self.navigationController.navigationBar.backgroundColor = [UIColor clearColor];
self.navigationController.navigationBar.tintColor = [UIColor whiteColor];
self.view.backgroundColor = [UIColor redColor];
}
Images are below. Should I take screenshots of the FindAssetLocationMapViewController attributes as well? Just to clarify, the nav controller and nav bar attributes do not have a class associated with them.
Try this code in your app delegate, then remove the code you have:
+ (UIImage *)imageWithColor:(UIColor *)color
{
CGRect rect = CGRectMake(0, 0, 1, 1);
// create a 1 by 1 pixel context
UIGraphicsBeginImageContextWithOptions(rect.size, NO, 0);
[color setFill];
UIRectFill(rect);
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return image;
}
Place this inside application:didFinishLaunchingWithOptions:
//create background images for the navigation bar
UIImage *clear = [AppDelegate imageWithColor:[UIColor clearColor]];
//customize the appearance of UINavigationBar
[[UINavigationBar appearance] setBackgroundImage:clear forBarMetrics:UIBarMetricsDefault];
[[UINavigationBar appearance] setBackgroundImage:clear forBarMetrics:UIBarMetricsCompact];
[[UINavigationBar appearance] setTranslucent:NO];
[[UINavigationBar appearance] setShadowImage:[UIImage new]];
As you can see, the UINavigationBar is fully transparent. Only the title and UIBarButtonItem is visible. And the status bar has the same colour as UITableView's background colour. Right now, I have finished to make the table view and cell has the same effect as the pic. But how to make the navigation bar and the status bar has the effect too?
Try this one
self.navigationController.navigationBar.shadowImage = [UIImage new];
self.navigationController.navigationBar.translucent = YES;
self.navigationController.view.backgroundColor = [UIColor clearColor];
[self.navigationController.navigationBar setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault];
Try this !
[self.navigationController.navigationBar setBackgroundColor:[UIColor clearColor]];
[self.navigationController.view setBackgroundColor:[UIColor clearColor]];
[self.navigationController.navigationBar setBarTintColor:[UIColor clearColor]];
I am trying to get an effect like this:
http://dribbble.com/shots/1473643-Fashion-app/attachments/219674
Basically I would like to extend the app background image to the Navigation Bar and the Status Bar.
Any ideas how to do this.
The following lines of code inside viewDidLoad of your vc will help you to have a similar effect:
self.navigationController.navigationBar.barStyle = UIBarStyleBlack;
[self.navigationController.navigationBar setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault];
self.navigationController.navigationBar.shadowImage = [UIImage new];
self.navigationController.navigationBar.translucent = YES;
[self.navigationController.navigationBar setTitleTextAttributes:#{NSForegroundColorAttributeName : [UIColor whiteColor]}];
self.navigationController.navigationBar.backgroundColor = [[UIColor blackColor] colorWithAlphaComponent:0.3];
