There are design patterns in software design and design patterns in UI design. Because the application of table views is extremely extensive in iOS, this section describes two UI design patterns in Table view: Paging mode and Drop-down Refresh (pull-to-refresh) mode. These two models have become the standard of mobile platform development.
Paging mode
Paging mode regulates the processing of a large number of data requests by mobile platforms.
Pull down Refresh mode
A drop-down Refresh (Pull-to-refresh) is a refresh of the table view or list to reload the data, which is widely used for mobile platforms. The Drop-down refresh is the opposite of paging, when flipping the screen to the top, and then pulling down the screen to start requesting the data again, the table looks at the head of the chart to see a wait indicator, the request end table as the head of the diagram disappears. The Drop-down refresh mode has an arrow animation effect.
