LGLAlertView prompt box and lglalertview prompt box

After iOS8 is used, the system's UIAlertController is encapsulated, saving a lot of code to be written every time you use it. After encapsulation, you only need a line of code, deome address: https://github.com/liguoliangiOS/LGLAlertView.git

Code LGLAlertView. h:
