rightbarbuttonitem not displaying

I have got following code for putting rightbarbuttonitem

UIButton* rightbutton = [UIButton buttonWithType:UIButtonTypeCustom];
    [rightbutton setBackgroundImage:[UIImage imageNamed:@"share-icon.png"] forState:UIControlStateNormal];
    [rightbutton addTarget:self action:@selector(share:) forControlEvents:UIControlEventTouchUpInside];
    self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithCustomView:rightbutton] autorelease];

But it is not displaying any barbuttonitem. Instead if I use following code then barbutton item appears but problem is i cant set touch event with this code on barbuttonitem.

UIImageView *iconView=[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"dashboard-icon.png"]];
    UIBarButtonItem *icon = [[UIBarButtonItem alloc] initWithCustomView:iconView];
    self.navigationItem.leftBarButtonItem=icon;
    [icon release];
    [iconView release];
Solution

  • Have you tried to set an appropriate frame for the rightbutton? e.g. rightbutton.frame = (CGRect){CGPointZero, image.size};

    Also note:

    On iOS 4 and later, the name of the file is not required to specify the filename extension. Prior to iOS 4, you must specify the filename extension.
