I have coded the app using XIB of 4.0 inch, when I run it in iphone with 3.5 inch the UI gets bad.
I am not using auto layout. So Now I want to know what should I Do to fix this issue ??
you can use auto resizing or u can make separate xibs for both

I'm creating an app using xcode 4.5 that is meant to support only the 3.5 inch retina display. Thus, in the attributes inspector for the view controller I have set the size to be 3.5 inches. However, I'm testing my app on a iphone 5 and the app auto-resizes to fit the whole screen. Do you know why this is happening? How can i make the app remain in 3.5 inches of size even when viewed off of a iphone 5?
Thanks
If you remove the default 568h#2x icon from your project the app will run the way you want. On the iPhone 5, you will get black bars on top and bottom to show what it would look like on the 4. Hope this helps.
The answer is - you can't do that :) But you can download ios5 simulator and set it's device property to 3.5 screen device
i was making an application is ios6 but i have to make it compatible for ios5 too. i made weak link to the libraries and they are working fine but one issue arises and i still not solve it. the problem is regarding iphone 5 and iphone 4 sizes. i had some questions:
in view under xib what i should pick view size iphone 3.5 or iphone 4?
if i place in buttons and other controls according to 4 size than they goes out when i run it on iphone 4 and vice versa?
should i need to make two xibs to overcome it?
or is there any other method which will resize my view and make it compatible for iphone 4 and 5?
EDIT
iam making application on ios6 and i want my application to run on both iphone 4 and 5.
thanks .
Generally you don't have to worry about this because iOS can move your controls around for you using either:
Auto sizing: If supporting iOS versions prior to 6, use the auto sizing masks (sometimes affectionately called "springs and struts", and when accessing programmatically, it's called the autoresizingMask) so that everything moves arounds appropriately. So select the "size inspector" and adjust the "autosizing" masks:
Autolayout: If you're developing an iOS 6 and above app, you can also use the new the "autolayout". See Cocoa Auto Layout Guide which has tons of relevant links. Also see the Xcode 4 Users Guide.
Turn autolayout on and off: If you want to develop an iOS 4/5 compatible app, you may need to turn off "autolayout". If so, go to Interface Builder, click somewhere on the background, select the "file inspector" in the right panel, and examine/change the "Use Autolayout" flag.
I'd suggest designing for the 3.5" screen. And let it resize or move your controls for the 4" screen.
I have an application in iphone market which works for iPhone 4s and lower version. So now iPhone 5 has been launched which bigger size screen, my question is what all changes i have to do in my application so that it will be compatible with iPhone 5 also.
1) Do i have to rebuild my app for iPhone 5?
2) Do i have to make changes only in UI ?
3) Will the iPhone 5 will its make it compatible?
Your valuable replies will help me a lot. Thanks in advance.
Here is my answers,
1) Do i have to rebuild my app for iPhone 5?
If you want to utilize the complete screen space, you can add Default-568h#2x.png and rebuild the app and release it.
2) Do i have to make changes only in UI ?
You can utilize the complete screen space for iphone 5. You can code for screen modifications in case of other iPhones.
3) Will the iPhone 5 will its make it compatible?
Yes. It will make it automatically compatible. It will add a black strip on top and bottom to compensate for the extra space in the screen unless you add Default-568h#2x.png.
If your app uses the standard UIKit provided by Apple, you only need to add a 4 inch launch image to your app, and it will automatically resized itself. But if your app using custom controls or graphics-heavy like in games, you might want to adjust the images and take advantage of the larger screen.
You also have to make sure the methods you used do not deprecated on iOS6 to prevent the app from crashing. Some references if you need further reading.
To make older app compatible with iPhone 5 You need to look for Following things.
Latest Xcode version 4.5.
Open your project and select Upgrade settings for new version.
Add Default-568h#2x.png for new resolution .
For UI you have to change your xib's object autoresizing property.When you select View Go to
inspector and select size property It will show you None, Full Screen, Retina 4 options . Set autoresize property for all your Buttons , labels and check xib for retina 4 and None both.It is same like you set it for Landscape and portrait .
5.Some other changed will be in code because some method has been depreciated for ios 6.0.
6. After doing all this .You can run it on iphone 5 simulator for testing.
I have an app that was using GLKMatrix3 and its supporting functions. I found that the GLKMatrix3Multiply function would always crash on iPhone 5 hardware. Easy to workaround using GLKMatrix4 instead, but the point is that I would never have found the problem without actually trying my app on iPhone 5 hardware.
I was told to file a bug for the GLKMatrix3 problem, so maybe this will be fixed. But the code runs just fine in the iOS 6 simulator.
I learned from this that, whether or not you need to rebuild your app for iPhone 5, you do need to at least run your app on a device before advertising support for that device.
Enabling Autolayout in .xib or .storyboard and adding a splash screen of 640px by 1136px enables iPhone 5 resolution support for the taller screen.
However, doing so, my app started to display some funny things where I assume autolayout is not a great idea.
I am wondering if there is a way to enable iPhone 5 device support, i.e. fix app's resolution without using Autolayout? Maybe I can set in the code?
If yes, then I will have no need to create 2 storyboards or nibs to support iOS5- and iOS6.
If you weren't using Autolayout before, you won't need to use it for iPhone 5 support.
When you're putting your interface together, you just need to check your bindings, and toggle between the taller phone size, and the regular phone size, as described here:
Xcode Storyboard displaying the new iPhone 5 screen size?
If your screens look fine in both screen sizes then you're done.
If you are doing a lot of coding to show your UI, then you'll have more work to do.
I found a great answer a couple weeks ago (link below). You will copy and paste your older iPhone Storyboard, rename it to reflect the iPhone 5, and press the button that expands the screen size, found on the bottom of the layout grid. Some minor coding adjustments might be needed, but this sample code is used in the AppDelegate to detect which device is running, and hence, which Storyboard to use. You'll just have to duplicate your interfaces, but these GUI changes can be made without code and without AutoLayout (also good to note that AutoLayout removes iOS 5--and lower--compatibility)
xcode 4.5 how to pick storyboards at launch
Have anyone figured out how to support both screen resolution iPhone4 and iPhone 5 ?
In iOS6 we have support of Autolayout. Can that be used for iPhone4-iPhone5 screen i.e. 320x480 and 320x568.
If we use auto layout feature for that we will have to keep deployment target minimum to iOS6. What about iOS5 than ?
What about iOS5 than ? Do we have to handle it programatically for different screen size ?
I searched web and could not find exact answer for that so posting this question though having doubt of having downvotes. Please bear with me for that. I guess this question is very basic to support new device in applications and is applicable to all developers.
If you want to support iOS 4.3 or 5 then turn off the Autolayout.Then you have to set the UIViewAutoresizing correctly either in code or interface builder.
With the autoresizingMask on UIView you can make the view stick to aside and grow with the size of the superview.
One other approach can be to design separate views for iPhone 5 and iPhone 4S.
Check screensize and load views accordingly, as in the case of universal apps.
