Linking canon 70dto ipad

I use an Eyefi memory card. You can only use them if you have an SD slot. I am not familiar with the 70D so not sure if you have that but the cards work well once set up.

I have the Canon 6D and use the wifi with Canon app to transfer them to both my iPhone and iPad. You can use the iPhone app for your iPad too.

Otherwise, to get them directly to the iPad, get the Lightning to SD card reader and just put in your memory card.
