I have a xib file that support IOS 6 and 7.
The problem is when i selected view as IOS 6 the frame from IOS 7 change, and vice versa.
Here is a screenshot, previewing the IOS 6.1.
I adjust the frame to (0, -3, 255, 85) and when adjust the frame using view as IOS 7 the frame becomes:
(-345,894,0,0).
When i adjust the frame using view as IOS 6.1 and early the frame changes for IOS 7.
I just want to use the same frame in both IOS version.
Some informations that may be relevant:
Was an existing project build for IOS 5.1 and later, then i update the project to support IOS 7.
When i made the update some views (include this one) have their frame changed to positions that does not make any sense and size their size set (0,0).
First i think was an interface builder issue preview issue, but i tested on devices with IOS 6 and 7 and the results are the same from the preview
Thanks in advanced!
When you assign bottom margin & top margin in Autoresizing tab, iOS 7 gets confused & produces strange effects.
I faced the same problem, & i solved it using height stretch. Refer image.
Use 'iOS 6/7 deltas' fields to adjust design element(s) position on your controller for different iOS.
You should setup your project (setup how UI view) for one of iOS versions (6.1 or earlier/7.0 or later) and then adjust interface by deltas to other version.
You also can use new preview mode to see difference between two operation systems on one screen.
Here is link to APPLE iOS 7 transition guide - https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/TransitionGuide/SupportingEarlieriOS.html#//apple_ref/doc/uid/TP40013174-CH14-SW1
First set your view size as none and then Set your frame using view as iOS 6.1 and earlier. Now test in iOS 6 and 7. It will automatically resize your view frame.

For example: I have set in a storyboard scene a vertical space constraint from de bottom of a UIButton to the bottom of the superview with a constant of 20. When running in an iOS 8 device, this is correctly shown, but when running in an iOS 7 device, it looks like this constant becomes higher and the button is shown upper in the screen... I don't understand why this happens, since autolayout is supposed to be available since iOS 7.
Any help? I don`t know how to handle this.
Thanks in advance
One of new things in iOS 8 is the Layout Margin. Layout Margin is a new property available in UIView for iOS 8. So, any objects inherit from UIView will have this property. If you are developing the app for both iOS 7 and iOS 8, you should not use Layout Margin (or use layout margin in a smart way).
So, if you have any constraints related to layout margin and you didn’t do a proper check before launching the app on iOS 7 devices, the app might crash or the arrangement of the objects might be out of order.
Whenever you are trying to add new constraints from the storyboard in XCode 6, “Constrain to Margins” is ticked by default. The meaning of this selection is to add constraints with the new property in iOS 8.
If the deployment target of your app is iOS 7 and above and any of your constraints have this layout margin, the XCode will complain with the warning “Layout attributes relative to the layout margin on iOS prior to 8.0″.
If you are developing the app for both iOS 7 and 8, it is best to “Untick” the Constrain to Margins.

Currently, I'm working on universal app (iPhone / iPad) supported on iOS 7 & iOS 8.
Here is my problem regarding size classes :
My navigation bar is defined into a XiB file (NavBarView.xib)
Inside this file, I have a UIButton that I want to display only on iPhone mode, and a UISearchBar only for iPad mode.
To handle that whitout any line code, I used the new feature "Use size classes" available for views since iOS 8. I defined "size classes" for these two elements inside my XiB file.
UISearch for Ipad : Installed for all layouts except Compact Width / Any Height (wC hAny)
UIButton fo Iphone : Not installed for all layouts but with Compact Width / Any Height (wC hAny)
This mechanism works pretty fine on iOS 8 for iphone and ipad, but not on iOS 7. However, if I apply these size classes direclty into views contained into the storyboard, it works for iOS 7.
Could anyone explain me why my size classes are not working when they are defined into XiB files on iOS 7 ?
Best Regards and many thanks,
Lorenzo.
Barely anything to do with size classes is supported under iOS 7. Some good answers here: How can Xcode 6 adaptive UIs be backwards-compatible with iOS 7 and iOS 6?
Adding as an answer since saadnib's comment on the original question helped me a lot.
Size classes on XIB files not being backwards compatible is a bug that has been fixed on xCode 6.1.1. Strangely it's not on the patch notes but I can confirm I'm using a single xib to provide 2 different layouts for a cell on iPad and iPhone. This only started working once I updated from 6.0.1 to 6.1.1.
Limitations on backwards compatibility for classes on storyboards still apply, but they can be worked around.
Figured another option. Size classes will not work, if you add xibs view as subview to UIApplication.shared.keyWindow.
View must be in UIViewController view hierarchy to support size classes.

My application is in iOS7 compatible, Xcode 5. Now, I have to make it iOS 6 compatible, so when I set deployment target iOS 6.1, all frame changes, what is solution for this?
I have attached screenshot for reference.
One thing to notice, I have used storyboard and have not used autoLayout.
First of all of you should understand new iOS 7 UI. Check it here: link
There are few differences in UI that are connected to status bar new visualization and etc.
I have noticed that some elements have different y offset positions for iOS 6 and iOS 7.
So if you use storyboard or xib you can find
So if you can find iOS 6/7 Deltas option. I've attache screenshot for you:
Just modify delta Y position for all of view using -20 value because of status bar issue.
Hope it will help you.
Select each ViewController in your Storyboard and, tick both options "Under top bars" , "Under bottm bars"
Programmatically you'd set your view controller's wantsFullScreenLayout to YES. It defaults to NO under iOS 6 but both defaults to YES and is deprecated as of 7. Or set the "Use Full Screen (Deprecated)" tick box in the interface builder.
Look Size Inspector at 4th position in the utilities area at right side and change value of delta Y in IOS 6/7 to -20 and delta Height to 20. I hope it will work
I Have Developed an Application. In that one i Added a GMSMapView and also Two Buttons at the Bottom. If i run this Application on iOS Simulator Version 7.0 all the outlets on the XiB are Visible. But If i run this Application on iOS Simulator Version 6.1 one of the Button is not Visible. Can any one please tell what is the Reason why it is hiding one button if the Height of the Device is Same.
You can use delta value that will effect the layout for the ios 6 not to the ios7
if you are set view as ios 7 in interface buinder you need to decrease you y position show image below
-64 delta y because you use navigationbar at top so it's size 44 and +20 for status bar
I am experience a rendering bug when using the default progress view. Rather than being 9px tall, the view is clipped to about 4px when using the default progress view. My app is built with the iOS6 SDK, and the issue appear when running on a iOS7 device. The interface is built with interface builder.
Is there a simple fix for this issue? Switching the style from "Default" to "Bar" in interface builder fixes the problem, but that changes the appearance.
Setting the frame in code helped me solve this.
#iPP 's answer is not the best. Setting the frame in code will cause your code to be riddled with iOS version checks, and that code tends to get very complicated when supporting multiple device orientations.
I think the best way is to use new feature "iOS 6/7 Deltas" in Xcode 5.
And "iOS 6/7 Deltas" key usage is:
When Auto Layout is turned off, you will notice an area in the sizing tab of the utility area (right pane) of Interface Builder that allows you to set iOS 6/7 Deltas. Deltas can be set individually for each view and work as you would expect. If your storyboard or nib is set to view as iOS 6, then setting the deltas will cause that view to be shifted and/or resized by the set delta amount when run in iOS 7. Alternately, if your storyboard or nib is set to view in iOS 7, then the deltas will be applied when run in iOS 6. Both of these tools help you to support older versions of iOS alongside iOS 7
for UIProgressView, here you can try to set "delta Y" to be -7px, because iOS 7 just reduce the Y origin of UIProgressView by 7 px, so when running in iOS7, we should give it back the 7px.
It's like the iOS7 cut the progress view use the iOS7 Style's frame.
You have two ways.
1. set the progress view style ---bar, you can do this in the nib file or code.
2. use the code to set the frame. Something like:
progressView.frame = CGRectMake(x,y,w,h);
The second will face the layout issue when you rotate or change the layout.
So the easiest way is set the progress view's style.
