Developer James Thompson discovered the latest in the code iOS 8 beta mentions of a new resolution that could Apple use with the larger 5.5-inch iPhone, which will be presented alongside iPhone 6. In the code iOS 8 beta 5 is supposed to hide mentions of the new display mode _@3x, which suggests that iOS 8 beta 5 is ready for a completely new resolution, apparently based on the current resolutions. This code also confirms that Apple is actually working on a new one Retina format, which now increases the resolution to three times, while previous devices increased the resolution to two times.
With the arrival iOS 7, application developers can also count on slightly easier optimization of applications for the new one Retina display, since iOS 7 is mainly based on vector graphics. At times of release iPhone 4 was still in iOS the dominant element was raster graphics, which had to be converted to a higher resolution, otherwise the graphic elements could be displayed blurred. Mentions of the new Retina the displays are additionally proof that Apple maybe for a 5.5-inch iPhone offer a resolution of 1704 × 960 points, or 1242 × 2208 points. In the first case, it would Apple tripled the "native" resolution iPhone 5, which is 568 × 320 points. In the second case, it has Apple to experiment with a completely new resolution of 414 × 736 points, which in iOS 8 hide mentions.
The claim "iOS 7 works mainly on vector graphics" is not true.
