I my application i'm trying to set images in imageView pragmatically. i'm using separate images for iPhone 5 and iPhone 6. What would be the suffix iPhone 6 images? as #2x is for iPhone 5 images.
It is the same, there is #3x for Iphone 6+.
Please refer https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/MobileHIG/IconMatrix.html#//apple_ref/doc/uid/TP40006556-CH27-SW1
#2x is not a suffix exactly for iphone5 - it's reprepresent of how much real pixel in one point in this image, so it can be used in any numbers of devices (available and new) what will have display with double density. As for iPhone 6+ (exactly 6+ for now) it use triple density display, so it used now #3x suffix.
You can do what you want programmatically - detect device and use the name you want. But #2x and #3x will be used (if available) dependently of device.

I've a question about resolution of Iphone 6 and Iphone 6 Plus.
I would like to know something about #x2 and #x3, i really need to be sure !
If i've a fullscreen UIImageView, display on a Iphone 6(667x375 points) the size of the containing UIImage have to be 1334x750 because the size in points are 667(#x2)x375(#x2), right?
So if i understand, the UIImageView on Iphone 6Plus in fullscreen is 736x414 but the resolution is #x3 then the UIImage in the UIImageView have to be 2208x1242 because the size in points is 736(#x3)x414(#x3), no ?
Then in a general case, i only need to know what is the size of my UIImageView and if the resolution is #x2 i multiply the size x2 and if the resolution is #x3 multiply the size x3?
Guys i really need a confirmation and if i'm wrong, please, explain me why !
I'm sorry if you think my question is really stupid but i need to understand how it works.
Cordially :)
Lets go for a ride of #1x, #2x and #3x image scaling and content viewer size according to different resolutions in iPhone.
Let understand some basics first
Device Resolution
================================
iPhone 4 & 4S 640×960
iPhone 5, 5C & 5S 640×1136
iPhone 6s 750×1334
iPhone 6P 1242×2208
Resolution reference from this site.
Now if how to use images with #1x, #2x & #3x.
Lets say you have an imageView in with size of 100W x 100H, to display images properly on all the devices with appropriate resolution without stretching or pixelation your image, one need to create 3 set of images as below according to device.
iPad 2, iPad mini supports #1x images, required image of size 100x100(WxH)
iPad, iPad mini supports #2x images, required image of size 200x200(WxH)
iPhone 4S, 5 & 6 supports #2x images, required image of size 200x200(WxH)
iPhone 6P supports #3x images, required image of size 300x300(WxH)
Though your UIImageView size is 100x100 for all the devices, but image displayed in different devices is different according to their resolutions.
Following size Table will give you more clarification, read more about it in apple documentation here
I hope it clears confusion about different resolution images for different devices :)
I apologise if this has been answered but I can't seem to understand no matter where I look. I have been trying to make a Chess game using SpriteKit in Xcode. I don't understand the 1x, 2x and 3x options in the assets folder.
It seems like the image is the smallest when I put it in 3x, which seems counter-intuitive. Also, what resolution is best to design for? It doesn't seem like the actual iPhone resolutions are used in the iOS simulator.
Thanks
You get a great overview from apples docs:
https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/MobileHIG/IconMatrix.html
Basically, you need images with higher resolution for devices with higher resolution. If an icon is 32x32 pixel for iphone 3, you add an 64x64 image for iphone 4 (retina, #2x) and an 96x96 image for iphone 6 (even higher resolution, #3x).
1x , 2x , 3x is different size of images according to different phone's resolution.
You can find imagesize according to device resolution in below link.
IconMatrix
Basically,
#1x images are for the iPhone 3GS - 'standard' resolution devices (3.5" screens)
#2x images are for the iPhone 4 and 4S which contain 3.5" Retina screens and also used for the iPhone 6.
Retina 4 #2x are for the iPhone 5 and 5s (4" Retina screens)
#3x images are for the new iPhone 6+,iPhone 6S+ (5.5" super-Retina [3x] screen)
Note :- As describe by apple in document
For all images and icons, the PNG format is recommended
Also, what resolution is best to design for?
The biggest resolution you will need. In most cases, #3x. So if the image "is" 10x10, design it being 30x30 for the #3x files, and scale down to smaller resolutions.
• 30x30 is the pic#3x.png
• 20x20 is the pic#2x.png
• 10x10 is the pic.png
The simulator uses the image according to the device it is simulating. So the iPhone 6S+ will use #3x if available.
PNG is the recommended extension, and you can use http://tinypng.com to reduce the file size, including splash screens.
I am using three versions of image:
abc.png
abc#2x.png
abc#3x.png
I just want to know that if I use abc.png wherever this image is used, does all the versions are automatically picked according to iPhone resolution or I have to make an image asset for this.
I did a Google search but nothing satisfactory found.
When we use any image in your app it pick the image according to the device resolution which set constraint by the APPle Inc.
The Asset is listed below for more clarity:
iPad 2 and iPad mini (#1x)
iPad (Air) and iPad mini (Retina) (#2x)
iPhone 4s (#2x)
iPhone 6 and iPhone 5 (#2x)
iPhone 6 Plus (#3x)
For all images and icons, the PNG format is recommended. You should avoid using interlaced PNGs.
I wish it'll help you.Let me know if further more concern.
only write #"abc".
it selects the desired image automatically
We are trying to make an app for all devices ,designing it on code only.
I could see that the suffix are :
#2x~ipad for ipad retina
#2x for iphone5 and iphone6
#3x for iphone6+
But there is something that i dont get, how is that the files for iPhone5 and 6 have the same suffix and the same name ? these images should be in a different size, and so you cant give them the same name ?
We have created images for iPhone6 with #2x and they seems great on the iPhone6 simulator, but on iPhone5 things dont look good and cover each other .
Cant you separate these files with a different suffix?
I have read this :
Image resolution for new iPhone 6 and 6+, #3x support added?
It is because iphone 5 and iphone 6 (not including the plus) have the same pixel density.
So basically a 40x40 image will look the same on both screens and will take the same space. You will just have to adjust positions to cover for the extra space on the iphone 6 screen.
Images for the iPhone 5 and iPhone 6 are the same size, and the same DPI. So they share the same suffix (#2x). They don't need to be separated.
#3x is for the iPhone 6+ because it has a higher DPI and a larger size than the other phones. Please refer to the Human Interface Guidelines for Images.
You should be using layout to determine how your UI elements are laid out on the screen, and you should be using Auto Layout to make sure they look right on all devices, independent of aspect ratio.
The #2x, #3x image sizes refer to device families grouped by resolution. iPhone 5 and 6 are in the same family, and iOS will use the #2x image for both. The size and placement of the UI element which uses that image, however, has nothing to do with the size of the image itself.
I want to support a variety of devices from iPhone 4S to iPhone 6+. Previously, when adding supporting for iPhone 5, we followed the following steps.
Add the launch Default-568h#2x.png
Use the same #2x images (640x960) which are resized automatically for iPhone 5.
Now, iPhone 6 and 6+ are introduced with varying sizes and it is written on most blogs that we will use #2x for iPhone 6 and #3x identifier for iPhone 6+. It is also written that:
iPhone 6+ (#3x) images will have resolution of 1242x2208 (I am using portrait mode), and it is automatically downsized.
iPhone 6 will use #2x images.However,I am not sure what the size of these images should be. Should they be 640x960 or 640x1136 or 750 x 1334. In case of using the first two sizes, won't the images be distorted?
I think what you are after is detailed in the HIG under "Icon and Image Sizes"
