[iOS base Control-4.1] App List

Requirements 1. Display app information in n Gongge 2.APP information including icon, name, download button 3. Use as little code as possible, read app information from plist, calculate location size information for each app icon a. Thinking 1.UI layout: N Gongge 2. Event monitoring 3. Dynamic Add (by plist) 4. Overall package, combining each application information, using the view's tiered wrapper help layout B. Implementation (using pure code)
