In which way the ios7 interface works differently than iOS6?
In a nutshell, most everything.
That was Jony's supposed driving force for the rework. Otherwise it would be rather odd for Apple/Jony to say that iOS7 works the same as before but is just nicer/newer looking (in their opinion).
The wholesale reinvention across the UI of moving to "text as buttons" is a huge functional change. To this day I have yet to read a solid explanation of what was broken before, and how the change is better and fixed/improved things. I’ve only sensed that the change was for something different and new. But it was a very poor decision for several reasons, and is much more than just an appearance change. First it's a step backwards for easy/quick cognition -- text as buttons removes the prior ability to clearly differentiate actionable items from info-only items, as well as for indicating "state," as in, enabled or not enabled. Secondly, it adds complexity that was previously necessary -- in the initial version of iPhone/iPad OS's, I thought it was wonderfully elegant and obvious how, when you opened a contact after a call or text, the number just used to contact you was highlighted blue. That stuck out for me since whatever phone I was using prior (Palm Treo?) did not have that feature that felt so "obviously" needed. With iOS7, blue text no longer could be used so they had to add a RECENT type of indicator, much less elegant.
The imagined strategy of using colored font to different actionable from info-only black font then removed the option to use different colored text in an app for indicating different states/info/options. Last, and maybe most importantly, the tap/contact area of a single word is much smaller than a button shape such that it's often hard to connect and get an action the first time, and secondly your fingertip covers the text so you lose the benefit of seeing a color change to indicate "pressed." Poor execution of a reinvention in iOS 7.
The forced-use of circles as an theme for indications and controls was (and remains) just dumb. 5 circles for signal strength indicators in place of the industry-standard bars was quickly fixed. The entire clock/stopwatch/timer app interface was wholesale unnecessarily reinvented from something that looked obvious for use instantaneously, to a minimalist space-age interface that took some thought to initially use. When apps got updated in iOS7, the entire icon was clouded out and a circular clock/circle would advance until it was updated. The shading was so dark, it was not possible to see what the app icon stood for, and depending upon the icon color, you couldn't see the update status circle itself. This replaced the blue bar that would advance across the bottom of the icon; nothing there was broken and in need of reinvention. Same for how a webpage would load in safari; before, the entire address bar would advance in blue left to right as the page load; iOS 7 brought in a simple small underline that would advance, which was hard to see unless you focused on it. Change for the sake of seeing something now, and not without negative functional trade-offs.
In fact, and I don't know if Apple/iOS 7 or Google is to blame, but the shifting towards using underlines to indicate a "selected item" is also a to-this-day poor "improvement." Less obvious for function, less elegant for form.
iOS7's pervasive shift towards using faint, light-grey text throughout was a huge interface change that was not only more difficult to read than darker text of the prior 3 decades of computers and hundreds of decades of the printed word/symbols, but also completely obliterated the decades-old understanding that light grey text meant not-selectable or not-selected (depending upon the button shading). Huge change from prior interface norms. Not sure what someone thought was broken before.
iOS7's calendar was an initial fail in that it was not possible to easily look at calendar entries in list view.
iOS7's weather app was a major fail in that the flat-design outline-only weather icons were difficult to read quickly and required extra time and concentration to understand. A hollow sun looked like a hollow cloud looked like a hollow gusty wind icon. What was wrong with a yellow sun, white cloud, and blue wind that used to enable instant understanding.
Well those are just some of the major interface changes, all for the worse, some of which were rightfully corrected quickly, and some of which still unfortunately linger to today.
The only thing I can’t honk of is swiping left to go back, the rest pretty much works exactly like before, with the interaction changeling only because things look different.
I found that reinvented interaction to be a change for the worse.
Similar to how iOS 7's app update circle obscured the app icon, the "slide the entire message to the left" for acting on emails was disrupting. Much preferred sliding and seeing buttons to press while still being able to recognize the message. iOS 7 slide the entire message line offscreen to where you no longer could see the message, which again, was a fancy new animation that didn't fix anything wrong before but also reduced the ability to see what you were acting on. Life is full of interruptions and sometimes when you're working on a mobile device, your attention is called away just after a swipe. Then when I return minutes later, I often have to unswipe to see the message again in order to act on it. The new animation swipe was merely fun for the design studio to work on something different; in real life, it doesn't offer much more than you had before other than being something different and new.
iOS7's voicemail message screen was pure utter trash, where tapping on any message resulted in the screen shifting and morphing into a completely different state. Any follow-the-bouncing-ball screen changes are unsettling and distracting when you have to move your finger and refocus on what you were working on. This is a reason the Backstage in Microsoft Office 365 apps is a fail to many. Before iOS7, maintaining the voicemail controls in one location atop the screen made much more sense and was quicker and easier to use.
As for the control center, it already existed in the jailbreak world in 2008 or so, it was hardly “invented” with iOS 7.
I agree and in an earlier post stated that iOS7 should be given no credit as being better because of control center. Control center could have been an added refinement to the prior iOS easily.
iOS 7 thru today's interfaces rely too much on exploration and discovery instead of baking in near-instantaneous obviousness based on human nature and decades of user interface best practices. Jony and his designers had time in their studios to massage their chins while ruminating thoughtfully when coming up with new "reinvented here" breakthroughs, while the users would benefit more from interfaces remained focused on refinements for being intuitive, efficient, and preferably thoughtfully beautiful.
Oh, I see. Yes, it was much more intuitive in the older interface.
As was most everything else.
Well, they mostly changed the looks, so it's kinda of changing the colour of your car, it's not that the previous one was wrong, only different.
Equating "changing the color of your car" to "iOS 7's interface vs. prior interfaces" makes sense only if you're changing from a blue SUV to a light silver left-hand-drive Prius.
Back to apple, I remember that El Capitan, Sierra and High Sierra had been accused of being “boring” updates, as they looked identical to Yosemite; Mojave brought dark mode and got much more interest with that.
Users wanting "exciting" OS overhauls are so barking up the wrong tree. Once you have a well-established interface, it makes so zero sense to do a 180-turn redesign. When it comes to fashion, food, wall colors...it feels OK to want something fresh and different. Plus those not wanting to change really need not change. However, at no time do manufacturers force across-the-board changes like relocating zippers and buttons to our backsides, or changing from a 3 or 4 pronged fork to 1-prong for the sake of something new. Nobody tears down the walls in the house and replace them with drop ceiling panels. But a change to (or back to) bell-bottom pants, fine. Change the wall colors, fine. Or refine a wall by replacing wood paneling with drywall. Great. The point is, it's great to desire a fresh coat of paint here & there, or more significantly, a great new app that uses an already-great interface. But wholesale reworking of basic interface elements that were previously refined after decades of learning only make sense if you're Google or Windows circa-2010 who's competing with Apple and needing to make something safely different... Apple's reworking their interfaces from 10 years ago made zero sense then and we're still paying for it in certain respects to today.
