I want Show my own App icon in the lower-left corner of iPhone Lock screen? can please give me some Suggestions? Like this﻿
You can't control what app appears in the bottom-left corner of the lock screen.  Neither can you add code to your app to make your app appear there whenever you want.  These are called Suggested Apps and it's a feature of iOS.

iOS controls what app appears there based on several factors, including your location, the apps on your device, and your history of where &amp; when you use those apps.  Together, iOS trys to present you with the app you would most-likely use at a given time, location, and history.

If you don't like this feature, it can be turned off in Settings -&gt; General -&gt; Handoff &amp; Suggested Apps.
