Working with iOS raises the bar for excellence in user interface design and offers great opportunities for you to deliver engaging and unique user experiences. Using the below common design concepts before you start coding you app to enhance the usability and appeal of your apps.
Always Format Content – When creating a layout that fits the screen of an iOS device. viewers should see primary content without zooming or scrolling horizontally.
When using Touch Controls – Use UI elements that are designed for touch gestures to make interaction with your app feel easy and natural.
Hit Targets – Create controls that measure at least 44 points x 44 points so they can be accurately tapped with a finger.
Text Size – Text should be at least 11 points so it’s legible at a typical viewing distance without having to zoom.
Contrast -Make sure there is plenty of contrast between the font colour and the background, so that the text is legible.
High Resolution – Provide high-resolution versions of all image assets. Images that are not @2x and @3x will appear blurry on the Hi res displays.
Distortion – Always display images at their intended aspect ratio to avoid any distortion.
Alignment – Align text, images, and buttons to show users how information is related.
