实现对UIAlertController和UIAlertView判断系统后的简单封装

来源：互联网发布：escape the fate 知乎编辑：程序博客网时间：2024/05/23 15:28

iOS8之后用UIAlertController代替了UIAlertView,所以每次有需要弹窗的时候,都需要先判断系统,最近在做的项目中弹窗较多,如果每次都判断,真是太麻烦了,索性对UIAlertController和UIAlertView进行的封装了,封装在一个工具类中,在工具类中就对系统进行判断,然后在你需要弹窗的界面直接调用这个工具类的方法就可以了,减少了代码的耦合.

这个工具类其实也封装的特别简单,因为都是用的系统的,分享出来给大家参考下:

首先是.h文件

@interface UIAlertTool : NSObject-(void)showAlertView:(UIViewController *)viewController :(NSString *)title :(NSString *)message :(NSString *)cancelButtonTitle :(NSString *)otherButtonTitle :(void (^)())confirm :(void (^)())cancle;;@end

只有这么一个简单的方法把你需要在弹窗中显示的内容以参数的形式传入就可以了

然后是.m文件的实现

#define IAIOS8 ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)#import "UIAlertTool.h"typedef void (^confirm)();typedef void (^cancle)();@interface UIAlertTool(){    confirm confirmParam;    cancle  cancleParam;}@end@implementation UIAlertTool-(void)showAlertView:(UIViewController *)viewController :(NSString *)title :(NSString *)message :(NSString *)cancelButtonTitle :(NSString *)otherButtonTitle :(void (^)())confirm :(void (^)())cancle{    confirmParam=confirm;    cancleParam=cancle;    if (IAIOS8) {                UIAlertController *alertController = [UIAlertController alertControllerWithTitle:title message:message preferredStyle:UIAlertControllerStyleAlert];                // Create the actions.        UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:cancelButtonTitle style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) {             cancle();                  }];                UIAlertAction *otherAction = [UIAlertAction actionWithTitle:otherButtonTitle style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {            confirm();        }];                // Add the actions.        [alertController addAction:cancelAction];        [alertController addAction:otherAction];                [viewController presentViewController:alertController animated:YES completion:nil];        }    else{        UIAlertView *TitleAlert = [[UIAlertView alloc] initWithTitle:title message:message delegate:self cancelButtonTitle:otherButtonTitle otherButtonTitles:cancelButtonTitle,nil];        [TitleAlert show];    }    }-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{    if (buttonIndex==0) {        confirmParam();    }    else{        cancleParam();    }}@end

你在弹窗中点击确定或者取消要实现的功能写在block里面传入就OK了.SO easy吧!
