I developed iPad tabbar application. I also use custom tabbar on left side. Bu Tab bar has white background along edges in landscape mode and also portrait mode. This area could not delete any of the method.
It sounds like the sizes you're using in your nib file don't match the layout in your app. You'll need to set the autoresizing mask of your views so that they resize correctly at runtime.
You can change the autoresizing masks in the nib by opening the right-hand pane; selecting the icon that looks a bit like a ruler, and then clicking the red arrows. Here's a picture:
The important arrows are the ones in the second row; click them so they look like this:
Your view should then resize correctly.

How can I remove the white bar at the bottom of my mobile app? I've tried the solution of adding a Launch screen in the Launch screen file but that didn't work. I've attached an image.
Just for a bit of context, I'm using a PageViewController to slide between 3 pages.
Any help appreciated.
It looks like you add static size view on the iPhone 6 screen in xcode UI constructor but launch it on the iPhone 6s Plus (with bigger screen).
To scale this view properly you should turn on Use Auto Layout in the Utilities bar and add constraints to the view
Make sure that the blue-colored view is properly constrained to the bottom of its superview.
I'm trying to use a UISegmentedControl as a custom right button bar item. Using Interface Builder, when I drag the control into the navigation bar, it gets sized to be quite wide (too wide, considering the segment contents):
I've tried setting the widths of the segments to something that I think looks good and the overall control resizes, but it is pinned to the left side of the original space it was allocated. I can't seem to find a way of moving it from there. Here's a picture of what this looks like in IB in landscape:
and here's what it looks like running on an iPhone 7 Plus simulator in portrait mode:
As you can see, the segmented control is positioned way too far toward the center.
I tried a hack (suggested in this thread) of embedding the segmented control inside another view, leaving the containing view to be full width of the bar button item and constraining the segmented view to be on the right of it's container. That gets it over to the right, but here's the effect of running that on an iPhone 7 simulator (somewhat narrower than the 7 Plus):
Here the problem is that the title, which is supposed to be centered, has been pushed off to the left. I assume that this is because the (transparent) bar button item is taking up so much more width than what is needed just for the segmented control.
Is there some way of getting the right button area of the navigation bar to simply be smaller?
My steps are below:
1.Drag the segment control to navigationbar:
2.Change the segment width:
3.iPhone7 & iPhone 7Plus all looks good:
I have two images that I am showing in a UIImageView, they both show up fine when they are edited on the extended storyboard and when ran in the 4in simulator. However when I switch the storyboard to the shorter 4 & 4S size the images disappear, the UIImageViews are still there however it will not display the images. The first picture is of the 4in storyboard and the second is of the 3.5in, all I did was click the resize button at the bottom of the editor to shrink it.
This sounds like a simple layout issue in IB. If you have Autolayout disabled then you need to set some struts for each of the images so that they reposition when the screen size changes. On the right side of IB in Utilities open the Size Inspector panel and set up the Autosizing as in the image below.
Notice only one strut is red, this keeps the content pinned to the bottom.
The bottom strip of my view in storyboard is not displaying on the iPad. I am not sure if it is not being drawn or if the view on Storyboard is too big.
UILabel is not hidden
Changing color of text has no effect
Everything else appears without issue
In the Attributes Inspector, I have size set to iPad Full Screen
Bottom Strip in Storyboard:
Bottom Strip on Simulator:
This is likely either a tab bar or a navigation bar that is not being accounted for. These can be simulated on IB via the attributes pane on the view controller you're working with.
I have a layout working fine in Xcode storyboard for a Master-Detail splitview app but when I run it in the Simulator or on an actual device it appears slightly messed up and I have no idea why.
The image in Xcode looks like this;
The layout in Simulator and Device looks like this
This is almost certainly a problem with the autoresizing settings of your subviews (aka "Springs and Struts").
You are building a UISplitViewController-based application. Note that the dimensions of your Detail View Controller's frame are different when your app is running in portrait vs landscape mode. In your storyboard screenshot above you see the landscape-sized frame. The screen capture from your simulator shows the portrait-size frame. You'll need to set the struts and springs of your subviews (the UIPickerView, the brushed metal buttons, the white box below, etc) so that these elements resize (or not) and maintain their relative (or absolute) position in the parent view.
The easiest way to do this is to set the values in your storyboard, using the Size Inspector in the right column. Select which element you want to change settings for and then look for this:
By clicking on the red arrows inside the inner box you will toggle on/off the "springs", which determine whether your subview expands when the parent view expands, or whether it maintains its original size when that happens. By clicking on the outer red I-bars you will toggle on/off the "struts", which determine whether you subview will maintain a fixed distance from its parent view's edge when the parent view's size changes. Setting the right combination of these will make your view to look correct in both portrait and landscape orientations.
You can also change these settings programmatically in your code by setting the view's autoresizingMask property. See for reference:
