IOS TableView performance Optimization and analysis

1. The most common use is cell reuse, registration reuse identifier

Each time you swipe the cell, you need to go to the cache pool to find a cell that can be recycled, and if not, recreate the cell

2. Reduce the number of controls in the cell

The View object minimizes the number of controls, avoids the consumption of more resources, and affects the performance of the rendering, and does not apply to hide

3. Use opaque view to avoid consumption performance to render

4. Use local update if you only update a group, use reloadsection for local updates

5. Use less AddView to dynamically add view to the cell, add it when initialized, and then control whether it is displayed via hide.

6. Load network data, download images, use asynchronous load, and cache.
