Bar Button Item is not Showing - ios

I am trying to create a bottom toolbar. So I dragged I Bar Button Item to the View Controller and it was automatically position at the bottom, see image below:
But when I run the app, it doesn't show the bar at the bottom.
I already added:self.navigationController?.navigationBarHidden = false

I think it's just only a constraints problem.
First of all check your Document Outline near to the left of your table, to see the position (toolbar is just below table):
Add your constraints and pay attention to all options as shown in the picture:
Then, take a look to the size inspector, for the table view:
And for the toolbar:
This configuration working both in portrait/landscape mode.

Drag UIToolbar controller directly instead of only UIBarbutton item.

self.navigationController?.navigationBar.hidden=false

Have you set constraints of UIToolbar? I just guess it can be one of the reasons why you cannot see your barbuttoitem.

The navigation bar and the toolbar are two different things and the toolbar is hidden by default. Try setting the toolbar hidden attribute to false.

Sometimes bar button item and bar button do not show when we present our screen. On screen we can then not see bar button item and bar button. So we need to push our screen if we want bar button item and rightBarButtonItem.

How to adjust the position of tab bar item iOS?

I want to create a custom tabBar like this
Now I just can create a tabBar as below, I want the 4 tab bar Items (the add sign is a button) to be centered and don't cover the button, so the cart icon should move to the left a little bit, and the mall icon should move to the right. But I don't know how to adjust the position of tab bar item, neither using storyBoard or in a programmatic way.
Thank you for your help.
You should try adjusting the insets for the individual icons. You can do this in the storyboard.
Check this post:
Moving UITabBarItem Image down?
Please modify Item Position in Attributes Inspector in Storyboard.
Select Item position as "Centered".
Choose Custom for Width and Spacing.
Play with the numbers for Width and Spacing and set it was you wish.

Remove the gray bar at the bottom of view controller - iOS

The image shows the View controller and the bar I want to remove. And also the structure of the view controller:
Someone told me how to remove the grey bar present at the bottom of the view controller as shown in the image. Unable to select and delete the bar. When I try to add the tab bar in that place, it goes behind the grey bar and becomes invisible.
What do your simulated metrics look like?
Can you get rid of the bar by changing the bottom setting?
Couple of things - if you are using autolayout, just make a constraint to the bottom of the container, with 0 value for the constraint. That will take it to the bottom. Second thing I would add is a zero size table view footer to the tableview.
This is a toolbar that comes with the UINavigationController that the View Controller is embedded in. Assuming you have a Navigation Controller on the storyboard connected to the view controller, select it and in the attributes inspector deselect "Shows Toolbar". If you want to do this in code you can get and set isToolbarHidden on a UINavigationController instance.

How to design a tabbar inside a view

I need to make this view:
A view on top of the tab bar with some data. (image, name, text, ...)
tab bar has a 3 page and every page has a separate view
When user scroll up, tabbar will be scrolling top of the page and a UILable stands top of tab bar. It can be show with some fading animation (not important right now)
this is after scrolling:
I search in cocopods but I didn't find solution.

I want to know how to put uitabbar inside a view. Is it possible ?
If yes, How to change just sub view of tab bar when I change tab bars!

Yes, but I wouldn't describe the thing you are showing in your screen shot as a "tab bar". It is a UISegmentedControl. So all you have to do is respond to the user tapping on a segment of the UISegmentedControl by substituting one view for another, and that's easy to do.

iOS storyboards - UINavigationBar not appearing when I add it

I added a UINavigationBar to a detail controller scene, but when I run my app the UINavigationBar does not appear. Why is it doing this ? I have the custom class set to the controller I want it too, but its not appearing, here is a screenshot.
but when I run this app, I dont see the "Title" bar or anything.
To add constraints select your navigation bar and click in the icon as in the picture.
uncheck "constrain to margins" as you want the navigation bar to snap in the boards of the screen, select the up and left red dots lines and add the value 0 to the drop boxes, meaning 0 pixels from the left and top of the screen.
Select Update frames and click in add constraints.
I can see in your screenshot you have other screen with problems (red icon next to the view controller) you should also fix that, click in the icon for more details about the error/warning
I am not sure if I understand what you are trying to do, but try this,
Select the detail view and go to the xCode menu and select editor->Embed in-> Navigation Controller.
I hope it helps
Add constraints to your navigation bar. However, IcaroNZ suggested the best way for navigation

Navigation Bar is too small

I am working on an iPad app and when I try to put the navigation bar on the first view controller, it fits in the main storyboard but is too small (also comes in contact with the status bar) when I run the simulator (as seen in the picture below):
The width and height in the storyboard are set to regular, not sure if it is relevant to this question. How do I fix this?
It looks like you're just adding a navigation bar. Are you sure you don't want a navigation controller?
If you do just want the navigation bar the you need to add constraints to pin it to the left and right of the screen.
Click the "add constraints" button and pin to left right and top.
Click on your view and go to Editor > Embed in > Navigation Controller.
