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> #import <UIKit/UIKit.h> typedef NS_ENUM(NSInteger, LGLAlertViewActionStyle) { 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 /** * 单个或者没有按钮 不执行任何操作 只是提示总用 * @param title 提示的标题 * @param message 提示信息 * @param btnTitle 单个按钮的标题名称 * */ + (void)showAlertViewWith:(UIViewController *)viewController title:(NSString *)title message:(NSString *)message buttonTitle:(NSString *)btnTitle buttonStyle:(LGLAlertViewActionStyle)buttonStyle; /** * 有两个或者多个按钮 确定 取消 * @param title 提示的标题 * @param message 提示信息 * @param btnTitle 单个按钮的标题名称 * @param cancelButtonTitle 取消按钮 * @param destructiveBtn destructiveBtn按钮 * @param otherButtonTitles 确定按钮 */ + (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; /** * 有输入框 确定 取消 (注： 这里只做了有一个输入框) * @param title 提示的标题 * @param message 提示信息 * @param btnTitle 单个按钮的标题名称 * @param cancelButtonTitle 取消按钮 * @param destructiveBtn destructiveBtn按钮 * @param otherButtonTitles 确定按钮 */ + (void)showAlertTextFieldViewWith:(UIViewController *)viewController title:(NSString *)title message:(NSString *)message TextFeildCallBackBlock:(TextFieldCallBackBlock)block cancelButtonTitle:(NSString *)cancelBtnTitle otherButtonTitles:(NSString *)otherBtnTitle; /** * 单个或者没有按钮ActionSheet 仅仅只是提示作用 按钮没有响应事件 * @param title 提示的标题 * @param message 提示信息 * @param btnTitle 单个按钮的标题名称 * */ + (void)showAlertActionSheetViewWith:(UIViewController *)viewController title:(NSString *)title message:(NSString *)message buttonTitle:(NSString *)btnTitle buttonStyle:(LGLAlertViewActionStyle)buttonStyle; /** * 没有按钮ActionSheet 按钮有响应事件 * @param title 提示的标题 * @param message 提示信息 * @param btnTitle 单个按钮的标题名称 * */ + (void)showAlertActionSheetWith:(UIViewController *)viewController title:(NSString *)title message:(NSString *)message callbackBlock:(CallBackBlock)block destructiveButtonTitle:(NSString *)destructiveBtnTitle cancelButtonTitle:(NSString *)cancelBtnTitle otherButtonTitles:(NSString *)otherBtnTitles, ...NS_REQUIRES_NIL_TERMINATION; @end
