介绍 LBToAppStore 评价提醒封装，使用应用版本、间隔天数与用户上次选择控制弹窗时机，再根据选择跳转到商店或推迟提醒，展示早期评价入口的实现思路。

原文署名 Bison，保留原发布时的内容。

**阅读前** 这是 2015–2017 年间的技术记录，本次整理未重新运行验证示例。原文发表于 2016 年，采用 UIAlertView、UIAlertController 和跳转商店的旧式提醒流程。

> "由于我自己的App下载量少，评论也少，出于App的aso优化，想尽办法，而评论是aso里边比较重视的一块，前面的版本都没有诱导用户评论的这一功能，导致有些被动。"

由此自己简单的封装了该功能，下面我们先看看效果图：

弹出试图并没有做什么处理，就是系统的8.0以前用的`UIAlertView`8.0以上用的`UIAlertController`

具体的一些算法，都可以看代码，闲话不多说，直接贴码，😄

新建一个NSObject的类命名为`LBToAppStore` 具体代码如下

## .h文件

```
#import <Foundation/Foundation.h>

#import <UIKit/UIKit.h>



@interface LBToAppStore : NSObject<UIAlertViewDelegate>
{
    #if __IPHONE_OS_VERSION_MAX_ALLOWED < __IPHONE_8_0

    UIAlertView *alertViewTest;

    #else

    UIAlertController *alertController;

    #endif

}

@property (nonatomic,strong) NSString * myAppID;//appID



- (void)showGotoAppStore:(UIViewController *)VC;

@end
```

## .m文件

```
#import "LBToAppStore.h"

@implementation LBToAppStore


- (void)showGotoAppStore:(UIViewController *)VC{
    //当前版本号
    NSDictionary *infoDictionary = [[NSBundle mainBundle] infoDictionary];
    float appVersion = [[infoDictionary objectForKey:@"CFBundleShortVersionString"] floatValue];
    //userDefaults里的天数
    NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
    int udtheDays = [[userDefaults objectForKey:@"theDays"] intValue];
    //userDefaults里的版本号
    float udAppVersion = [[userDefaults objectForKey:@"appVersion"] intValue];
    //userDefaults里用户上次的选项
    int udUserChoose = [[userDefaults objectForKey:@"userOptChoose"] intValue];
    //时间戳的天数
    NSTimeInterval interval = [[NSDate date] timeIntervalSince1970];
    int daySeconds = 24 * 60 * 60;
    NSInteger theDays = interval / daySeconds;

    //版本升级之后的处理,全部规则清空,开始弹窗
    if (udAppVersion && appVersion>udAppVersion) {
        [userDefaults removeObjectForKey:@"theDays"];
        [userDefaults removeObjectForKey:@"appVersion"];
        [userDefaults removeObjectForKey:@"userOptChoose"];
        [self alertUserCommentView:VC];
    }
    //1,从来没弹出过的
    //2,用户选择😓我要吐槽，7天之后再弹出
    //3,用户选择😭残忍拒绝后，7天内，每过1天会弹一次
    //4,用户选择😭残忍拒绝的30天后，才会弹出
    else if (!udUserChoose ||
    (udUserChoose==2 && theDays-udtheDays>7) ||
    (udUserChoose>=3 && theDays-udtheDays<=7 && theDays-udtheDays>udUserChoose-3) ||
    (udUserChoose>=3 && theDays-udtheDays>30))
    {
        [self alertUserCommentView:VC];

    }

}

#endif


@end
```

具体使用方法如下：

```
#import "ViewController.h"
#import "LBToAppStore.h"
@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

-(void)viewDidAppear:(BOOL)animated{

    //用户好评系统
    LBToAppStore *toAppStore = [[LBToAppStore alloc]init];
    toAppStore.myAppID = @"1067787090";
    [toAppStore showGotoAppStore:self];

}


@end
```
