I'm personally of the opinion that all we're doing with iOS 7 is taking something which is badly designed (and lets face it - had it been submitted anonymously to dribbble before the reveal, it'd be seen as below par).

Here, I've taken the viewpoint of "I accept that this terrible new design is going ahead", but still noticed an inconsistency, so thought I'd point out my improvement to it. But that's hard to put into 140 characters (including a link).

I absolutely agree that the iOS 6 share button is better.

Often times I'll share something I hate, but feel passionately about. Example: I wouldn't 'Love' an article about a tragedy, but I might want to share it to increase its visibility. In this case, tapping a heart shaped icon would be very inappropriate.

It doesn't make sense in static screenshots but when you actually use it I think it's far easier to understand than the previous icon. The new one indicates that when you press it that a menu will slide up from the bottom, which it does. The old one didn't really have any relevance. To me it looked like some kind of 'open in new window' button.

That being said, it doesn't work as well on the iPad as the menu doesn't slide up.

And honestly does anyone really think Apple would just change the icon for the sake of it? They could of easily made the edges thinner to fit in with iOS 7 but they didn't because they think every change through and choose the best one.
