iOS中 LGLAlertView 提示框的实例代码

使用与ios8 以后，只是把系统的uialertcontroller进行了封装，省的每次用的时候要写很多的代码。封装后只需要一句代码即可 , deome 地址

上代码lglalertview.h：

#import <foundation/foundation.h>
#import <uikit/uikit.h>

lglalertviewactionstyledefault = 0,
lglalertviewactionstylecancel,
lglalertviewactionstyledestructive
};
/** alertview的回调block */
typedef void (^callbackblock)(nsinteger btnindex);
/** alertview的回调block */
typedef void (^textfieldcallbackblock)(nsstring * text);
@interface lglalertview : nsobject
/**
