Adding UINavigationBar to UIView Programmatically?
Solution 1
If you are using the navigation controller from the first view I suggest this in your Appdelegate.m
UIViewController *viewController = [[MenuViewController alloc] initWithNibName:@"FirstViewController" bundle:nil];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewController];
self.window.rootViewController=navController;
but if you have a view which presents your new view that you want have a navbar use this for showing the new view:
UIViewController *viewController = [[MenuViewController alloc] initWithNibName:@"MenuViewController" bundle:nil];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewController];
[self presentViewController:navigationcontroller animated:YES completion:nil];
then you can add your navBarButtons in second view like below:
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
UIBarButtonItem *btnAdd = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(btnAddGroupPressed)];
self.navigationItem.rightBarButtonItem=btnAdd;
}
return self;
}
Solution 2
I'm not sure what's going on. Here is the code that I'm using to reproduce your issue:
The *.h file is empty
#import "STTestView.h"
@implementation STTestView
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// Initialization code
UINavigationBar *navBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, 300, 50)];
navBar.barTintColor = [UIColor purpleColor];
[self addSubview:navBar];
UIBarButtonItem *doneItem = [[UIBarButtonItem alloc] initWithTitle:@"done" style:UIBarButtonItemStylePlain target:self action:@selector(done:)];
UINavigationItem *navItem = [[UINavigationItem alloc] initWithTitle:@"categories"];
[navItem setRightBarButtonItem:doneItem animated:YES];
[navBar setItems:[NSArray arrayWithObject:navItem] animated:YES];
self.backgroundColor = [UIColor darkGrayColor];
}
return self;
}
-(void)done:(id)sender {
}
@end
And this is what I'm getting:
Can you please:
- Add the code for the whole
initWithFrame:
method? - Make sure that self.frame and headerHeight are in fact set correctly by the time your code runs?
- Remember not to use the
backgroundColor
property but thebarTintColor
property
Hope this helps!

I cannot tell you why, but I have experienced this same issue and I traced it to the setBackgroundColor
method. To get around it I did:
UINavigationBar *navBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, screenWidth, 44.0)];
UINavigationItem *titleItem = [[UINavigationItem alloc] initWithTitle:@"MyNavBar"];
NSDictionary *titleAttributesDictionary = [NSDictionary dictionaryWithObjectsAndKeys:
[UIColor whiteColor],
UITextAttributeTextColor,
[UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0],
UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, -1)],
UITextAttributeTextShadowOffset,
[UIFont fontWithName:@"HelveticaNeue-Light" size:20.0],
UITextAttributeFont,
nil];
navBar.titleTextAttributes = titleAttributesDictionary;
navBar.items = @[titleItem];
navBar.tintColor=[UIColor blueColor];
[self addSubview:navBar];
Solution 4
Perhaps, you forgot "navBar.items = @[navItem];" as I dealt with similar issue:
UINavigationBar *navBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, self.frame.size.width, headerHeight)];
navBar.barTintColor = [UIColor blueColor];
[self addSubview:navBar];//it is important point, otherwise, you can see only the area without any item
UIBarButtonItem *doneItem = [[UIBarButtonItem alloc] initWithTitle:@"done" style:UIBarButtonItemStylePlain target:self action:@selector(done:)];
[navItem setRightBarButtonItem:doneItem animated:YES];
[navBar setItems:[NSArray arrayWithObject:navItem] animated:YES];
Use these properties: "barTintColor" to get the color of the navigation bar background, and "tintColor" for the navigation items and bar button items.

I am trying to add a UINavigationBar to a UIView programmatically and having so success, and can't figure it out. I am trying to add it in my UIView subclass and it simply isn't showing up when I run my app.
Here is my code:
UINavigationBar *navBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, self.frame.size.width, headerHeight)]; [navBar setBackgroundColor:[UIColor blueColor]]; [self addSubview:navBar]; UIBarButtonItem *doneItem = [[UIBarButtonItem alloc] initWithTitle:@"done" style:UIBarButtonItemStylePlain target:self action:@selector(done:)]; UINavigationItem *navItem = [[UINavigationItem alloc] initWithTitle:@"categories"]; [navItem setRightBarButtonItem:doneItem animated:YES]; [navBar setItems:[NSArray arrayWithObject:navItem] animated:YES];

Josh Kahane almost 11 yearsThanks for your suggestion but I have explained in the question. I am trying to add a UINavigationBar to a UIView. No controllers are part of this issue.
