LGLAlertView 提示框

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：https://github.com/liguoliangiOS/LGLAlertView.git

上代码LGLAlertView.h：

#import <Foundation/Foundation.h>

    LGLAlertViewActionStyleDefault = ,

    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

/**
