Button not show in the navigation bar

Question

I try this code for the navigation bar

UINavigationBar *navbar = [[UINavigationBar alloc]initWithFrame:CGRectMake(0, 0,320, 70)];

and for the button I tried this code

UIBarButtonItem *add=[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(SaveButtonClicked:)];
self.navigationItem.rightBarButtonItem=add;

after this code i declare SaveButtonClicked method also.

When I try this code there is no error in this code and compiled successfully but the button is not show in the navigation bar.

Help me with right code and suggestions.

Where are you adding the navbar to the view hierarchy? Normally that is part of a UINavigationViewController. — picciano, May 21 '16 at 14:19
you need to provide more code about how is this `navbar` used — Yuchen, May 21 '16 at 14:53

1) You don't need to create a UINavigationBar. The navigation controller you're in provides that.

2) And if you did think you needed one, that probably means your view isn't in a navigation controller at all. Check what the value of self.navigationItem is. I imagine you'll find it to be nil. That means you need to redo your interface so this view is actually inside a navigation controller. "Embed in Navigation Controller" under "Editor" in Interface Builder may be of assistance there.

After you have created navigation bar

 UINavigationBar *navbar = [[UINavigationBar alloc]initWithFrame:CGRectMake(0, 0,320, 70)];

Then You need to create navigation item. and add navigation item to navigation bar

UINavigationItem *item = [[UINavigationItem alloc]init];
UIBarButtonItem *add=[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(SaveButtonClicked:)];
item.rightBarButtonItem=add;
navbar.items = [NSArray arrayWithObjects:item, nil];
[self.view addSubview:navbar];

Hope this Helps!

you can just use this single line to achieve that:

self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc]initWithTitle:@"Save" style:UIBarButtonItemStylePlain target:self action:@selector(saveButtonClicked:)];

after this add this method

-(void)saveButtonClicked:(UIBarButtonItem *)sender{

}

for more you can refer Add button to navigationbar programmatically
