问题 I am trying to use the NavigationController's toolbar in my app. This toolbar's toolbarItems are suppose to change depending on which view controller is presented. this is very basic. What I am trying to do is to add custom buttons to the toolbar using the UIBarButtonItem's "initWithCustomView:" method. However, the button won't show up on the toolbar.

问题 In a UIToolbar , I have added a UITextField to the middle of the bar (which gets added as a UIBarButtonItem ) with another UIBarButtonItem (Action button) next to it.

I have the following code: In my AppDelegate: // Get instance of Toolbar

问题 I am trying to create a custom UIToolbar that I can add to multiple views, I don't want to do this programmatically so I am using xib to design a UIToolbar.

问题 I have a problem when dragging a navigation bar or toolbar (storyboard) to my view controller. UINavigationBar: As you can see in the image above, the right button is almost overlapping the status bar. With a UIToolbar it happens the same: This view controllers are intended to be used as a Modal, that's the reason I'm not using a UINavigationController. In another section I use a UINavigationController and it appears as I expect: How can I drag a UINavigationBar / UIToolbar to a view
