I am working on a template for an iPhone App and was wondering what dpi resolution is used for it ? 300 or 72 ?
I am not sure and I hope somebody can answer me that question.
iPhones
iPhone 1/3G/3GS 320 x 480 163 ppi
iPhone 4/4S 640 x 940 326 ppi
iPhone 5/5C/5S 640 x 1136 326 ppi
iPhone 6/6S 750 x 1334 326 ppi
iPhone 6 Plus/6S Plus 1080 x 1920 401 ppi
Without downsampling: 1242 x 2208 461 ppi
Except for the 6th generation (= 5th) iPod touch,
all the models are equal to their iPhone counterparts
iPads
iPad 1/2 768 x 1024 132 ppi
iPad 3/4/Air/Air 2 1536 x 2048 264 ppi
iPad Mini 1 768 x 1024 163 ppi
iPad Mini 2/3/4 1536 x 2048 326 ppi
iPad Pro 2737 x 2048 264 ppi
Apple Watches
Apple Watch 38 mm 272 x 340 326 ppi
Apple Watch 42 mm 312 x 390 326 ppi
The original iPhone screen has a resolution of 163dpi - use that in your template if you want to be able to print your screen designs at actual size .
72是图像的dpi
鉴于iPhone和模拟器之间的dpi不同,您可能希望在iPhone屏幕上使用480x320的原始像素值。
The iPhone screen has 163 DPI, but I've found that images at that resolution appear too small in Xcode and Interface Builder. I recommend pretending that the screen has 72 DPI when making bitmap images for the iPhone, but remember that the screen has 163 DPI if you're drawing a ruler.
