I want to dismiss my navigation bar image(not the background image).That is i have set navigation bar image on the left side . when i go to the next controller the image overlaps the back button . This is my home screen with image in blue marked .
And this my second screen With image overlaped

UINavigationBar *bar = [self.navigationController navigationBar];
UIImageView *barImg=[[UIImageView alloc]initWithFrame:CGRectMake(2, 3, 49, 39)];
barImg.image=[UIImage imageNamed:#"smalllogo.png"];
[bar addSubview:barImg];
[barImg release];
Now i dont want the image in my other screens what can i do for that?

Answer 1

One thing you can do is Add your image in side the viewWillAppear: method and remove it from the navigation bar when viewWillDisappear: method. Related code block as follows.
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
UINavigationBar *bar = [self.navigationController navigationBar];
UIImageView *barImg=[[UIImageView alloc]initWithFrame:CGRectMake(2, 3, 49, 39)];
barImg.image=[UIImage imageNamed:#"smalllogo.png"];
barImg.tag = 100;
[bar addSubview:barImg];
[barImg release];
}
- (void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
UINavigationBar *bar = [self.navigationController navigationBar];
[[bar viewWithTag:100] removeFromSuperview];
}
Or Here's another simple solution. Add below code segment to viewWillAppear: method
UIBarButtonItem *item = [[UIBarButtonItem alloc] initWithCustomView:[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"smalllogo.png"]]];
[self.navigationItem setLeftBarButtonItem:item];
[item release];

Answer 2

You have added the image in the navigation bar but not removed it before moving into other view.
Use `
-(void)viewWillDisappear:(BOOL)animated{
[barImg removeFromSuperview];
}`
to remove it from superview.
