Apple launches iPhone 6 (4.7 inches,1334X750 pixels) and iPhone 6 Plus (5.5 inches,1920X1080 pixels).It means that developers will have to redo extra work to make their apps compatible on larger zscreens,right?.Now, there are 1.3 million apps on iOS, there's a good chance that developers are likely to look to update their apps to take advantage of extra resolution.
Phil Schiller, marketing chief of Apple, said the company's iOS 8 platform has a “desktop-class scaler” that allows apps to adjust to the various screen sizes. Schiller highlighted CNN's app without any code tweaks. "It just works," said Schiller.
Apple has cleverly kept the same 16:9 aspect ratio for its screen, which means current apps will automatically scale up to fit the device.It will just scale everything up and the aspect ratio is the same it shouldn't matter if you had hardcoded values or not.
In scaling up, however, these apps won't retain the same pixel density — which means some apps might look blurry and jaggy until you scale up all their image assets.
Now,Apple’s auto-scaling technique is a reasonable solution for you.
If You want to Update your Apps:
1.To support the new resolution,you need to deal with more available width and height
2.You need to redesign most of the images to be more flexible.
3.Icons and UI elements will need to be provided in @1x, @2x and @3x .
4.The iPhone 6 Plus even has a landscape version of the home screen, so you should be more anxious to see how our apps working in landscape mode.
