Asynchronously loading data in iOS is more efficient

Asynchronously loading data in iOS is more efficient

In the development of some time although the data can also be returned from the server, but we need to speed up the display of data according to the actual situation, so we use asynchronous loading data.

Let's look at how to load data asynchronously

Dispatch_async (dispatch_get_global_queue (0, 0), ^{

Download data (this is written using afnetworking request data)

Dispatch_async (Dispatch_get_main_queue (), ^{

Update the view (what is written here is to show the data)

});

});
