Just having an Xcode issue that I'm sure is tied to some setting I can't find. Im my storyboard, my content fills the entire view (i.e a background image), but then when I run my app in the iPhone 6 simulator, the background image and all the content don't fill the entire screen. There is white space to the right of and below the content on the simulated "screen".
When I run the app in the iPhone 5 simulator, this isn't an issue and it fills the entire simulated view.
So, what did I miss? I want to make my app work on all models of the iPhone.
Thanks for any help!
There are several ways to solve this, and I guess you are using View Size as Inferred or iPhone4 Inch in Attribute Inspector.
First way is to use AutoLayout at Storyboard to add Constraint.
If you don't want to use this, you should at least set the Autoresizing at Size Inspector.
"White space to the right of and below the content" sounds like there are scroll bars being displayed in your window. The iPhone 6 simulator is a different size, as well, which would account for them not being there on the iPhone 5 sim.
Have you tried going to the Home Screen (Shift + Command + H) in your simulator, and seeing if the white bars remain? On my computer, the white bars are always visible. Annoying, yes, but they don't cover anything or hide any part of the view. It's just a bit of white padding on two sides.

In my iOS app, I just want to have a button located in the middle of screens of multiple devices (like iPhone 6, iPhone SE, iPad Air).
However, surprisingly, it seems not intuitive to do (at least not as Android) in XCode + Xib.
Following shows a trivial example of this problem where I put the button aligned to the middle:
However, unless the "dimension" of the view is set identical to fit the installed device, there is no way to display the button in the middle.
Add horizontal and vertical center constraints as follows and it will always keep your button at center of any screen as shown in the image below
You can also add distance constraints to borders of the screen :
Example
I'm using xcode 6.1.1 version and iPhone 6 plus as testing device. I simply add a button at the right side of my xcode user interface, selecting Simulated Metrics size for iPhone 5.5-inch like this :
But when I run this on device the button goes far away from the right edge. Like this (Snap shoot from my device):
But when I select Simulated Metrics size for iPhone 4.7-inch like this :
It shows accurately in my device. Like this (Snap shoot from my device):
I tried with selecting and un selecting Auto Layout & Size Classes but do not get any clue. My device is 5.5 inch iPhone 6 plus. I even recheck it from my iPhone's packet and by IMEI Number. My question is why it is acting like iPhone 6 interface?? Is it for any reason of retina display or non retina display??
Thanks a lot in advanced.
My button's Constraints:
Select the button/ view you want. Then simply use the shortcut ⌥⇧⌘=. This will Reset to Suggested Constraints.
For this to work successfully, try moving your button to the suggested areas, i.e. move the button/ view to the top right corner like you have till the dotted blue lines appear.
Once done it should show what you expect on the interface builder but to be sure test on the simulator and/ or Device.
You need to add the proper constraints. Using simulated metrics is only for setting things up in IB, it has no effect on what the view looks like at run time. You should leave that setting at inferred.
If you don't add constraints yourself, the system adds them for you, and it adds top, left, height, and width constraints; that is not what you want. You need to add constraints to the top and right side. If you do that, the button will appear with that spacing to the right side, no matter what size screen you're using.
I think you should use constraints to solve the problem but i don't know the exact cause of this
Ctrl + drag from the item to the border in the storyboard to add constraints
Getting through some introductory swift and playing with Xcode and I basically just have a page with some color squares, background color etc. Doesn't do anything. Problem is when I compile the code it will run in simulator just fine and show everything perfect, BUT when I rotate the device, everything disappears and it only gives me a blank white screen. Rotating right or left does it. The only view that shows it is the original upright view (for all iPhone devices that I tested on through the simulator).
Xcode 6.1.1 and iOS Simulator 8.1 are being used on my MacBook Air with OSX 10.9.5.
In the App general page, I have already checked under Deployment info that Landscape Right and Left are both checked on. Storyboard is set on Any H and Any W.
I'm not sure what I'm doing wrong and it has been pretty difficult searching since I'm still new to iOS development I'm not sure I'm using the right words or whatever because I can't find an answer.
Summary:
App displays properly in iOS Simulator, Portrait View but no other views work and will display blank white screen instead.
In order to see if your views are actually being drawn and just off screen as others have suggested capture the view hierarchy. Go to 'debug' in the menu, then in 'view debugging' click capture view hierarchy. This will pause your app and create a 3D representation of all view on your screen which you can move around by clicking and dragging.
Are your views actually being drawn? If yes are they drawing off screen? If yes then you need to fix your constraints.
It sounds like you haven't set your constraints appropriately. Try setting the top and leading constraints for each of your views to something less than 320 (should cover all device sizes). Fix your warnings, then try again. I believe the views are simply off the screen.
You don't have the correct auto-layout UIConstraints set in interface builder. Check the document outline view in interface builder and ensure that you have appropriate constraints set on each view.
Auto Layout issues occur when you create conflicting constraints, when you don’t provide enough constraints, or when the final layout contains a set of constraints that are ambiguous.
Check this Apple documentation out, it will show you step by step how to resolve your (common) issue.
I am using Xcode 4.5.1 to create a very simple, single view iPhone app. I've laid out the view as you can see in the IB image. (UIViewController, UIView, UIButton, UITextView).
When I run the app in the simulator (or my phone) it looks like the second screen shot.
I don't understand why the simulator UI doesn't look like the one I created in IB.
What am I missing?
Thanks!
If you look you are using the iPhone 5 size layout in your storyboard file. To change the dimensions between iPhone 5 layout and the standard iPhone size
Click on the icon in the lower right hand corner of the storyboard:
Alternatively, if you want to see the layout in a iPhone 5 simulator. In the iOS simulator go to Hardware > Device > iPhone (Retina 4-inch). This is the iPhone 5 layout. However, if you do not have a retina displayed computer. The iPhone will look like a really big iPad.
It looks like you have an iPhone 5 sized layout in Xcode and a iphone 4 in simulator. Check the constraints on the dark grey vs bottom views and make sure that they'll resize how you want.
Hey so here is another method.
My Problem:
1.My Storyboard was showing a fat rectangle that didnt look anything like a iPhone. Then when I'd run the simulator all the element were cut off and not in the right position.
2.Simulator took up the whole screen.
Resolution:
1. Make sure you Storyboard is open and displayed, click on the frame so that it has a blue highlighted border. Then on the Utilities manager (on the right) click on "Show the Attributes menu". The very first item should be Simulated Metrics. Choose the size that best fits your screen/needs.
2.Follow Adjusting the XCode iPhone simulator scale and size I scaled it down to 33%
Best,
Nate
I am using Xcode 4.5 and iPhone 4 and 5 simulator, and the Interface Builder would add a UIButton in the top half of the screen with a top constraint, and add a UIButton in the bottom half of the screen with a bottom constraint.
It works fine on an iPhone 5 simulator, but on the iPhone 4 simulator, the buttons can overlap, or the bottom button may even get positioned above the top button.
I think it is due to the constraint, such as the bottom button "must be 250 points away from the bottom margin". I can't delete the constraint, and if I change it to "250 points or less", it won't work, if I change it to "250 points or more", it won't work either.
Is there a way to:
1) Make it have no constraint, but just position at absolute x and y? (or what about the spring in the past, so that everything is more spaced out in iPhone 5?)
2) Make the NIB into a one for iPhone 4 and 4S only, so that the app works well on iPhone 4 and 4S and just "black barred" on the iPhone 5.
3) Make it work well on iPhone 5 and work well on iPhone 4 as well?
If you know solutions to only (1), (2), or (3), above, please give it regardless, as it is still a viable solution for the transition period.
It is actually very easy to reproduce: Create a simple Single View app using Xcode 4.5, and drag one button just above the center point of the screen, and another one just below the center point of the screen. Then run it on the Simulator. On iPhone 5, it is:
And now stop the app, and change the Device in the Simulator to iPhone 4S (3.5 inch Retina). If you don't stop the app first, the Simulator can crash. Now run the app again, and the buttons will overlap:
I had the same problem, and it was due to a wrong settings for autosizing. To change the autosizing, click on the control in the interface builder, go to the size inspector.
Notice the bold red I's in the autosizing grid, they control placement when the screen is resized (like when going from iPhone 3GS to iPhone 5.
I think it will work best for you if you make your autosizing look like this:
I'm not sure, since I haven't used constraint-based layout (and won't until we drop support for iOS 5). Traditional NIB-based autoresizing will do absolute coordinates.
You can't do that for just one screen, as far as I know — you can disable it for your whole app by removing Default-568h#2x.png.
I'd go for programmatic layout, or if you want the easy way (which will be a pain to maintain), different nibs for different screen sizes. Note that you'll want to correctly handle the in-call status bar too...
EDIT: Put the two buttons in a container view and make the constraint center the container inside its parent? It won't adjust the spacing between buttons, but should look okay on both devices.
Select your buttons and add "vertical spacing" constraint for them. And set "less than" for top/bottom margins.
