CGFloat Debug Release, cgfloatdebug

The default values of uninitialized CGFloat variables are different in the debug and release environments. Today, people around me have called this bug for a long time and finally changed it, record the problem for your reference and initialize the alert variable .....

In the Debug environment, the CGFloat variable is initialized to 0 by default, and has not changed since then. However, in the Release environment, the CGFloat variable is initialized to 320 by default, but later changed to 568
