I am trying to create a mobile ios app for photo sharing similar to instagram
Notice 2 things:
Original image aspect ratio of the square photo is preserved (nothing is cropped out)
Link "Instagram" points to the instagram page of the photo https://instagram.com/p/72U--QKh5EDiTeBDvqSpKqltAkgog3HwaWqGI0/
I am really not clear and based on the documentation from here (checkout point no.4):https://developers.facebook.com/docs/sharing/best-practices#images
"We've also redesigned link page posts so that the aspect ratio for images is the same across desktop and mobile News Feed. Try to keep your images as close to 1.91:1 aspect ratio as possible to display the full image in News Feed without any cropping."
I have searched many blogs and ios developer forum to get best answer of my problem but I am not unable to find it, make sure that shared image is 1.91:1 to prevent anything cropped out. Can anyone provide me a clear guideline/doc on how to share a "square" photo and preserving the aspect ratio displayed in facebook timeline (and provide a specific link to the photo page)?
