项目中添加一个应用评分功能,其实就是做一个弹出框,跳转到App Store 中我们的应用位置,需要在开发者平台上App信息找到我们的App的AppID,有这个我们就可以跳转到我们的应用了

创建一个类,提供两个接口,一个是appID,还有一个推出这个控制器方法,在.h文件中声明以下属性和方法:
UIAlertController *alertController;/// 这个是推出提示的控制器
@property (nonatomic,strong) NSString * myAppID;//appID

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

.m代码如下:

- (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"] floatValue];


NSLog(@"%.2lf",[[userDefaults objectForKey:@"appVersion"] floatValue]);

//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，5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10天后，才会弹出
else if (!udUserChoose ||
         (udUserChoose==2 && theDays-udtheDays>5) ||
         (udUserChoose>=3 && theDays-udtheDays<=7 && theDays-udtheDays>udUserChoose-3) ||
         (udUserChoose>=3 && theDays-udtheDays>10))
{
    [self alertUserCommentView:VC];
    
}

使用的方法:
在合适的位置:

   //用户好评系统
    DAppStore *toAppStore = [[DAppStore alloc]init];
    toAppStore.myAppID = @"你的应用的appID";
    [toAppStore showGotoAppStore:self];
