iOS中 LGLAlertView 提示框的實例代碼

 更新時間：2016年09月30日 11:14:33   作者：ljmaque  
這篇文章主要介紹了iOS中 LGLAlertView 提示框的實例代碼非常不錯，具有參考借鑒價值，需要的朋友可以參考下

使用與iOS8 以后，只是把系統(tǒng)的UIAlertController進行了封裝，省的每次用的時候要寫很多的代碼。封裝后只需要一句代碼即可 , deome 地址

上代碼LGLAlertView.h：

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
typedef NS_ENUM(NSInteger, LGLAlertViewActionStyle) {
LGLAlertViewActionStyleDefault = 0,
LGLAlertViewActionStyleCancel,
LGLAlertViewActionStyleDestructive
};
/** alertView的回調(diào)block */
typedef void (^CallBackBlock)(NSInteger btnIndex);
/** alertView的回調(diào)block */
typedef void (^TextFieldCallBackBlock)(NSString * text);
@interface LGLAlertView : NSObject
/**
* 單個或者沒有按鈕 不執(zhí)行任何操作 只是提示總用
* @param title 提示的標題
* @param message 提示信息
* @param btnTitle 單個按鈕的標題名稱
*
*/
+ (void)showAlertViewWith:(UIViewController *)viewController title:(NSString *)title
message:(NSString *)message buttonTitle:(NSString *)btnTitle
buttonStyle:(LGLAlertViewActionStyle)buttonStyle;
/**

* @param title 提示的標題
* @param message 提示信息
* @param btnTitle 單個按鈕的標題名稱
* @param cancelButtonTitle 取消按鈕
* @param destructiveBtn destructiveBtn按鈕
* @param otherButtonTitles 確定按鈕
*/
+ (void)showAlertViewWith:(UIViewController *)viewController title:(NSString *)title message:(NSString *)message
CallBackBlock:(CallBackBlock)textBlock cancelButtonTitle:(NSString *)cancelBtnTitle
destructiveButtonTitle:(NSString *)destructiveBtnTitle
otherButtonTitles:(NSString *)otherBtnTitles,...NS_REQUIRES_NIL_TERMINATION;
/**

* @param title 提示的標題
* @param message 提示信息
* @param btnTitle 單個按鈕的標題名稱
* @param cancelButtonTitle 取消按鈕
* @param destructiveBtn destructiveBtn按鈕
* @param otherButtonTitles 確定按鈕
*/
+ (void)showAlertTextFieldViewWith:(UIViewController *)viewController title:(NSString *)title message:(NSString *)message
TextFeildCallBackBlock:(TextFieldCallBackBlock)block cancelButtonTitle:(NSString *)cancelBtnTitle
otherButtonTitles:(NSString *)otherBtnTitle;
/**

* @param title 提示的標題
* @param message 提示信息
* @param btnTitle 單個按鈕的標題名稱
*
*/
+ (void)showAlertActionSheetViewWith:(UIViewController *)viewController title:(NSString *)title message:(NSString *)message
buttonTitle:(NSString *)btnTitle buttonStyle:(LGLAlertViewActionStyle)buttonStyle;
/**
