My problem is that I have skipped support for the Iphone 6P screen size due to time constraints. In other words, the app that is to be released will work on Iphone 4-6, but not 6P. What I want is either to not release the app for Iphone 6P (is that possible?) or, in the best case, make the autoresizing work for Iphone 6P like it did before I added the launchscreen for Iphone 6 (note: no launchscreen for iphone 6P).
tl;dr:
How do I make the auto appresizing work for Iphone 6P but not Iphone 6? Alternatively, if that is not possible, how do I skip support for Iphone 6P altogether, i.e. so that it does not appear in App Store for those devices?
Unfortunately, I'm afraid it can't be done. As long as you support iPhone 6 you have to support iPhone 6+. And you cannot tell the app to resize just for the 6+.
I'm sorry, you'll have to work all night long. :) But with autolayout and size classes, it can be achieved quite easily: https://developer.apple.com/design/adaptivity/

Yesterday I had to change my iphone 4S to 5C and now something is wrong in my xcode app. When I run the app in my iPhone 5C it shows some top and bottom black borders. I have search some on Google and here, but they are talking about put the 3 image launch (and I need help with that).
Any help will be much appreciated, because I'm stuck at the moment and I want to work it for 4 and 5.
Thanks in advance.
Apparently your app was built prior to iPhone 5 release (which was back in 2012), so the app is quite outdated. The reason for the black bars on top and bottom is that you do not have a iPhone 5 launch image in the app and your app is not optimised for iPhone 5 (and newer).
My recommendation is to take a look at iOS 8 and rebuild your user interface to support adaptive layouts, because you will also need to support iPhone 6 and 6+.
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.
Sorry, perhaps because I'm not English, I don't know, but I cannot find any resource to a couple of questions; maybe I'm using not the correct words..
I would like to know something more about the different resolutions of the iPhone 4 and 5.
First of all: how can I tell my iPhone Simulator to simulate the "letterbox" graphics if I develop an app optimized for iPhone 4 resolution??
I would like to see how it appears but I have not the iPhone 5 yet
Second: what happens on the iPhone 4 if I design an app for the iPhone 5 resolution?
I mean, what does an iPhone 4 user see??
Can you please recommend me something article or similar to learn something more about these problematics?
Thanks
EDIT
I was making right!
The only things that makes the app running in letterbox mode with IOS 6 + iPhone 5 is the presence of the Default-568h#2x.png file for the splash screen.
I restar both the iPhone5 and Xcode, clean the project and compile it again. It works.
First: There are different simulators for each iPhone type. To change between them, open the simulator. Go to the Hardware menu bar item, then change which you want under device.
Second: You should be designing interfaces that scale however you can determine if you have a larger screen and change how it looks on the iPhone 5. If you are using standard components Xcode will try and upscale everything to look proper. However you should test to make sure it looks how you want on each device.
I'm looking at the iPhone 5 specs, and see that the screen resolution is 640x1132 or so, which would break some of my manual+storyboard interface layouts. I'm wandering how to make an app so it would either show on iPhone 5 in 640x960 screen (with black bars), or exclude my app from sale to iPhone 5 at all, as I do not want to worry about the interface breaking. Is this possible for existing apps?
Thank you for your input!
Unless you include a Default-568h#2x.png image in your application, it will not run at full iPhone 5 resolution.
In the Apple keynote on the 12th Sept 2012, they said all current applications in the app store would run on the iPhone 5 with without a problem using the black letterbox at the top and bottom.
The way to remove the letterbox is by providing a Default-568h#2x.png image, like duskwuff mentioned. If its not there, the device will run the application will run at 640x960.
So I'm currently making an app that supports both iphone 3gs and ipad (this is a universal binary app).
What I'm wondering is how will iphone 4 users view my app, will they see it pixelated? will they not see it full screen since my iphone 3gs is on a smaller resolution?
I don't have an iphone 4 yet but I'd rather just release this app as is - just for 3gs and ipad. Is there anything that I must know / any precautions etc? Oh (i just thought of this) is there an iphone 4.0 simulator so i can check out if my app works okay?
Thanks!
Basically any bitmap graphics (PNG files) will look a little blurry on the iPhone 4's Retina display.
The easiest way to fix this is to make double scaled versions (100x100 becomes 200x200) of all your PNG files and add them to your project suffixed with "#2x.png". In other words, MyBitmap.png will become MyBitmap#2x.png. Luckily your code doesn't have to change. On the iPhone 4 the OS will automatically choose a #2x.png instead of the regular one when you do:
UIImage *myBitmap = [UIImage imageNamed:#”MyBitmap.png”];
Xib files will also use the #2x.png if there is one available.
Other than that there's also launch images and Application Icons to worry about. This blog has a good summary.
Yes you can change your device type, by in the simulator pressing: Hardware->Device->iPhone 4 If you don't have it you might want download the latest devevloper tools.
Also you might have to press Window->Scale->100%
