I am using the UIBarButtonItems to trigger special actions but I also want to add another button on the bottom part of the screen with the same dimensions as the ones created in the NavigationBar, how could I do this?
Can I do it in the Interface Builder with some fixed width/height constrains or do I have to do it programatically, if so could you give me an example?
Thank you
The easiest way would be to add a UIToolbar to the bottom of the view. If your view controller is in a UINavigationController, the best way to do this would be to add the bar button items, either in Interface Builder by drag-and-drop or programmatically using setToolbarItems.

I want to add an button right to the search controller in the navigation, but am not sure how can I implement that... any Ideas?
Am doing it programmatically
I want to replicate this
Use a Horizontal StackView and embed a search bar on the left, and a button on the right. Set the button's imageView to the "gear" image or whatever image you'd like.
I want to move the navigation controller bar to the bottom of the view controller. How can i get this done ?
I tried :
self.navigationController!.navigationBar.frame = CGRectMake(
0,
UIScreen.mainScreen().bounds.height - 50,
UIScreen.mainScreen().bounds.width,
50)
This is moving to the bottom but hiding all other controller objects and also back button is not woking.
Sujay U N,
You should not try to move the UINavigationBar provided by the embeded UINavigationController to the bottom of the screen. Trying that will obvisoulsy move all the view's below it causing all the controller objects to hide.
Workaround
Approach 1:
Consider using ToolBar :)
Toolbar is designed to be placed at the bottom of the screen. If you are using xib or storyboard you can pick toolbar from components library and place it on your ViewController's bottom and then apply autoresizing masks or constraints properly :)
Now in order to show the back button make use of UIBarButtonItems. Change the style to custom and provide it arrow image or provide default style as done.
Though now you are all set to go :) You will notice UINavigationBar at the top of your view controller. In order to get rid of it,
select your ViewController, select its TopBar property set it to none :)
Approach 2
Use UINavigationBar.
Specific about using Navigation bar and dont want to use toolbar, well you can do the same thing with UINavigationBar as well.
Drag the UINavigationBar from components library place it at the bottom of the screen. Drag the UIBarButtonItem drop it as leftBarButtonItem, change the barButtonItem image to your back image. ( Same process as UIToolBar just use UINavigationBar instead)
Understand this is not same as the navigation bar provided by the embeded NavigationController. So get rid of NavigationBar at the top of your ViewController same as I explained above here as well
Finally,
In both the cases, draw an IBoutlet from barbutton item and handle poping the viewController programmatically.
Happy coding :)
I've subclassed UINavigationBar, I wanted to have a UIView contains UIImageView + UILabel inside it, I'm able to achieve it by setting titleView property. But, what I want to know is whether its possible to add it inside subclass directly?
Better way add one UIView on Navigationbar and then add any component on that so it is easy to manage those component because if you add component on left button right button and title label it not that much flexible to customise (i.e. if you added any component on titleLabel you can set that component frame only equal or less that title label. but if you add on UIView on Navigation bar then you can customise all components easily)
I hope it will help you.
I'm trying to make an app with a toolbar that can be resized. Basically, the toolbar can alternate between being at the bottom of the view and being at the top. When a button is pressed, it switches from one to the other. The problem is that when it is at the top, I want the size of the toolbar to expand to accommodate the status bar, but I don't know how to do this.
I've seen some solutions for changing the toolbar size but they all seem static and not something that can be changed with the tap of a button. Any suggestions on how to do this? Perhaps a different solution altogether?
You can use a normal UIView and customize it so it looks like a UIToolbar, then just set constraints using AutoLayout and animate the height-constraint.
I need to do exactly what the photos app is doing when you press the select button. Basically just hides the UITabBar and presents a UIToolbar. For some reason this seems to be incredibly difficult if you don't want to implement a complete hack. I found a hack if you shrink the height of the UITabBar and change it's alpha to 0 but when you set it's height back to the default the image and text is condensed.
Turns out that I ended up just needing to call [self.tabBarController.tabBar setHidden:YES] to hide the tabBar and instead of using my existing UINavigationController's toolbar I create my own instance of a UIToolbar and add it as a subview of my view controller. Then using autolayout I pinned it to the leading, trailing, and bottom edge of the view. This handles rotation and other issues.
