I have a scroll View. Now i need to add a tool bar when a button is clicked (above the tab bar). Since this is a scroll View, even if the user scrolls the page down the tool bar should be visible right above the toolbar.
my solution so far;
1.) i added the toolbar to a Window, and display the window (But i don't want to use a Window). Is there a way to do this using a UIView ?
My pseudocode : ToolBar ---(added to)--> UIWindow ----(display)--->
display
Create a containing view to house both your scroll view and the toolbar. Initially have your scroll view the full size within the containing view. Resize it smaller on button press and add the toolbar below it. When you hide the toolbar do the reverse (remove the toolbar from the containing view and resize the scroll view back to taking up the full view).

I created a tab bar with UIView in the storyboard, and after that I decided to add a UIImageView under the tab bar view. The image must be at the bottom, behind the tab bar, but the image view overlaps my tab bar. How do I lower my image view's z-index to fix the problem?
I've already tried moving the tab bar up in the Document Outline:
Pictures for understanding:
First make sure the Document Outline is opened in your storyboard. It's the icon at the bottom-left of your screen.
Then just drag the image view before the tab bar. This will bring it to the bottom.
I have a UIView that I can drag around the screen via UIPanGestureRecognizer. However, when I drag it down to the bottom of the screen, the view automatically starts to squish vertically when it touches the tab bar. If I keep dragging downward, it will eventually be allowed to drag under the tab bar.
I don't want it to interact with the tab bar at all though. It should just slide under it as if it weren't there. The view controller has Extend Edges Under Top Bars and Extend Edges Under Bottom Bars checked.
Why is the view interacting with the tab bar in the first place? And how do I prevent this behavior?
Finally fixed this by unchecking the "Extend Edges Under Bottom Bars" option on the view controller. The view now slides unimpeded under the tab bar.
I have a UITableViewController with a nav bar up top from an embedded nav controller. In between the nav bar and the start of the cells I'm trying to add a textfield and button sort of like a search bar layout but for a different purpose.
On my storyboard, I can drag in a button or a label, but it automatically fills the width of the scene. As a result there is only room for one or the other. I tried editing with the size inspector in the right pane but it reverts to the old number everytime.
How would I pull this layout off?
Create a view with the label/text field and the button then drag the view to the top of the tableview. It will add the view as a header view.
I have started an app using story board.
In that i have used tabbar controller
In a view, I have Table view in that having a custom cell, And I have added a search bar at the top of the Table view. as shown bellow
The problem is when I add Search bar very close to the navigation bar, It does not display and if i added little down it was displayed
what was the issue is in 2px difference?
Go to IB Inspector
Select search bar and set AutoSizing Mask like this attached Picture.. Enable left, right, top and center position.
I have a tab bar view, and another UIView which contains a button, which needs to be visible just above the tab bar.
I have added another view which always sits above the current select tab's view, but can't figure out how to make it sit just above the tab bar Screenshot http://img.skitch.com/20090524-jq6ufyiwp6c2uu1x5tkrrsd97m.jpg
I would suggest sub-classing the tabbar to include the new view. That way you do not have to worry about a tab overlaying the view. All your resizing should be done automatically and you will never accidentally hide a component.
You can also have the controller also look after the button and view that you add. you would just need to replace the tabbar in the tabbarviewcontroller to be your one.
Add your view with button in the tab bar view and use either one of these
– bringSubviewToFront:
– insertSubview:aboveSubview:
to put it above all and check how many pixels you need to position your button so that it does not get above the tabs.
You could also add it at the window level.
