, even if it was successful for a user in the past. There are multiple reasons why a connection fails. Maybe the User Agent rejects your access for security reasons, maybe the device storage is limited. In the face of active and rapidly evolving potential user agents, it is unwise to make assumptions about users' machines, software and capabilities. For example, when a user uses a handheld device, the data they can freely dispose of may only contain a few megabytes.

Ccsprite is the most commonly used class. It uses images to display the Sprite on the screen. There are three ways to create the sprite ):
// 1. Create a file directly through ccspriteGenie
Ccsprite * sprit = [ccsprite spritewithfile: @ "1.jpg"];
Cgsize size = [[ccdirector shareddire] winsize];
Sprit. Position = CCP (size. Width, size. Height );
Sprit. anchorpoint = CCP (1, 1 );

Although the above program code can run normally, there will be two records in the MERs table representing the same business entity, so they do
