I set up a tableView with the Interface Builder and put a red View above the TableView like this:
But while runtime the red View gets hide by the Navigationbar, so i have to set a constraint with Autolayout like this:
But that can not be correct...what i´m doing wrong?
More Information which my help:
This is because iOS7 allows views to be displayed beneath it. You need to use an offset to push the view down below the navigation bar like you are doing. You could also set the navigation bar to not allow items beneath it by unchecking
under top bars
If you use xibs instead of storyboard add this into your view controller.
self.edgesForExtendedLayout = UIEdgeRectNone;

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.
I'm trying to add a custom view above the navigation bar as displayed on the following image .
What I've tried so far is to add the view as a subview of the navigation bar - Did not work
Add the custom view first on Interface builder and then add a navigation bar manually - This seems to mess up with my navigation as the default navigation controller has it's own navigation bar.
Is this a bad approach on its own ?
If this is a view that will appear above all navigation bars in the app, why not use a Container View?
Make the Container View fill the screen, but give it a 20 point top margin to fit your custom green view. Then when you add your main view controller (wrapped in a navigation view controller) to the Container View, it will show your green view above it.
If you don't want your margin in a particular screen, do the following:
Add a constraint to the top margin and add an outlet to it so you can modify the constraint's constant in code.
Then, in any screens where you don't need the margin, access the parent view controller view and set the constraint's constant to zero.
let myParentViewController = self.parentViewController as? MyParentViewController
myParentViewController.myTopMarginLayoutConstraint.constant = 0
Don't forget to reset it to 20 (or whatever) when you go to a screen where you need the top margin again.
I have a UITableView inside a UINavigationController that's inside a UITabBarController. There is a view on the bottom (I'll call it bottomView) between the table view and the tab bar that needs to stay at the bottom as the table view scrolls, so I can't put it as a footer in the table view.
The issue is that when i scroll to the bottom of the table view, there is an empty space the same height as the tab bar between the lowest content (and the scroll bar) and the top of bottomView.
I think this is because the table view is trying to automatically compensate for the tab view at the bottom, but I can't position it all the way at the bottom because of bottomView.
here's my IB layout:
and the display (last tableViewCell highlighted):
If I understand your question correct you need to set a contentInset to your tableView like this:
[self.tableView setContentInset:UIEdgeInsetsMake(0,0,44,0)];
Edit:
Ok I think I got it. Set:
self.automaticallyAdjustsScrollViewInsets=NO;
I've seen this same nav controller->tab bar->tableview situation frustratingly cause the tableview to partially overlap with the navigation bar, instead of not reaching the tab bar. To anyone having this issue when using a UITableView: ensure your navigation bar is not translucent. If you want to use this setup with a translucent navigation bar, select the UITabBarController in the Interface Builder and uncheck the "extend edges under top bars" option in the attributes inspector.
I am a beginner using storyboards for iOS. I have been using the tab bar controller to show my content.
When I first implemented the UITabBar I could see all the icons at the bottom of the UITabController in storyboard and I could see the UITabBarItem at the bottom of each UIViewController. Why is there now a blank grey bar? I can't seem to change the content either in storyboard. I tried adding another UITabBarController but got the same problem, it also has a dark grey bar at the bottom. However when I run the app all the icons appear. How do I fix this so I can see the UITabBarItems in storyboard or should I just try updating them programmatically instead?
Showing a tab bar or not is one of the couple of simulated metrics used in Interface Builder. As such they only serve to have an idea of how your controller would look under different conditions but do not really change anything to the actual controller.
Most of the time the default Inferred option will try to deduce from the Storyboard configuration how it should look like. In your case just connect the tab bar controller to your controller through the viewControllers outlet.
In contrast, below you have some View Controller properties that change both how your controller is previewed in Interface Builder and also its actual behavior (for instance try changing Adjusts Scroll View Insets or Extended Edges).
I want to add a segment controller to the navigation bar not as the title, but like this:
How can I do that?
The problem is that it looks like this uses the navigation bar's title, which is actually in the same place as where you want your segmented control to go. Instead, you need to add a "prompt" to the navigation bar to increase the height of the bar, and add the prompt text above the content area of the bar.
This can be done purely in Interface Builder as illustrated by the screenshot below, or programmatically using the following code:
[self.navigationController.navigationItem setPrompt:#"some prompt text"];
I've had to do the same and simply added the segmented control inside a view added under the navigationbar bottom.
