My app has a cover photo feature and I have no idea on how to do it after taking a picture/upload from photo library.
How do I allow user to pick a portion of their photo to be their cover photo(example from the screenshot below)?

Yes but I'm still unsure how to have a box to drag and crop that portion out only – Happiehappie Nov 30 '15 at 07:12

Off the top of my head, you can take a photo then present it in a VC like this and then use gestures to drag the box around while performing the action on choose to crop the image within those bounds. I am sure there must be some thirdparty resource for this. Like this https://github.com/heitorfr/ios-image-editor . You can translate it to swift I assume – NSNoob Nov 30 '15 at 07:15
