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block */typedef void (^CallBackBlock)(NSInteger btnIndex);/** alertView的回調block */typedef void (^TextFieldCallBackBlock)(NSString * text);@interface LGLAlertView : NSObject/*** 單個或者沒有按鈕 不執行任何操作 只是提示總用* @param title 提示的標題* @param message 提示資訊* @param btnTitle 單個按鈕的標題名稱**/+ (void)showAlertViewWith:(UIViewController *)viewController title:(NSString *)titlemessage:(NSString *)message buttonTitle:(NSString *)btnTitlebuttonStyle:(LGLAlertViewActionStyle)buttonStyle;/*** 有兩個或者多個按鈕 確定 取消* @param title 提示的標題* @param message 提示資訊* @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 *)messageCallBackBlock:(CallBackBlock)textBlock cancelButtonTitle:(NSString *)cancelBtnTitledestructiveButtonTitle:(NSString *)destructiveBtnTitleotherButtonTitles:(NSString *)otherBtnTitles,...NS_REQUIRES_NIL_TERMINATION;/*** 有輸入框 確定 取消 (註： 這裡只做了有一個輸入框)* @param title 提示的標題* @param message 提示資訊* @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 *)messageTextFeildCallBackBlock:(TextFieldCallBackBlock)block cancelButtonTitle:(NSString *)cancelBtnTitleotherButtonTitles:(NSString *)otherBtnTitle;/*** 單個或者沒有按鈕ActionSheet 僅僅只是提示作用 按鈕沒有響應事件* @param title 提示的標題* @param message 提示資訊* @param btnTitle 單個按鈕的標題名稱**/+ (void)showAlertActionSheetViewWith:(UIViewController *)viewController title:(NSString *)title message:(NSString *)messagebuttonTitle:(NSString *)btnTitle buttonStyle:(LGLAlertViewActionStyle)buttonStyle;/*** 沒有按鈕ActionSheet 按鈕有響應事件* @param title 提示的標題* @param message 提示資訊* @param btnTitle 單個按鈕的標題名稱**/+ (void)showAlertActionSheetWith:(UIViewController *)viewController title:(NSString *)title message:(NSString *)messagecallbackBlock:(CallBackBlock)block destructiveButtonTitle:(NSString *)destructiveBtnTitlecancelButtonTitle:(NSString *)cancelBtnTitleotherButtonTitles:(NSString *)otherBtnTitles, ...NS_REQUIRES_NIL_TERMINATION;@end
