问题:

Whenever i click on this area , action also perform on this.

回答1:

Don't worry about this behavior, iOS auto tapp near element if there is not other element.

If you really want to prevent to click except button, then you have to put Element on unused area which should be inherited from UIControl or able to get UserInteraction.

Also, you can try this: (Swift version)

    let btnName = UIButton()
    btnName.setImage(UIImage(named: "settings_filled_25"), forState: .Normal)
    btnName.frame = CGRectMake(0, 0, 30, 30)
    btnName.addTarget(self, action: Selector("toggleRight"), forControlEvents: .TouchUpInside)

    var rightView = UIView()
    rightView.frame = CGRectMake(0, 0, 30, 30)
    rightView.addSubview(btnName)

    let rightBarButton = UIBarButtonItem()
    rightBarButton.customView = rightView
    self.navigationItem.rightBarButtonItem = rightBarButton
