ios一天显示一次广告或弹窗

废话不说，直接上代码

//一天之内只能批量邀请一次
    NSUserDefaults *userDefault = [NSUserDefaults standardUserDefaults];
    //    NSLog(@"之前时间：%@", [userDefault objectForKey:@"nowDate"]);//之前存储的时间
    //    NSLog(@"现在时间%@",[NSDate date]);//现在的时间
    NSDate *now = [NSDate date];
    NSDate *agoDate = [userDefault objectForKey:@"nowDate"];
    
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setDateFormat:@"yyyy-MM-dd"];
    
    NSString *ageDateString = [dateFormatter stringFromDate:agoDate];
    NSString *nowDateString = [dateFormatter stringFromDate:now];
    //    NSLog(@"日期比较：之前：%@ 现在：%@",ageDateString,nowDateString);

[[BaseHttpRequest sharedInstance] getWithUrl:url_ad parameters:dic success:^(NSDictionary *responseDict, NSInteger code, NSString *message) {
        if (code == 1) {
                if ([ageDateString isEqualToString:nowDateString]) {
                    NSLog(@"一天就显示一次");
                }else{
               
                //创建视图
                [self creatLiBao];

                    NSDate *nowDate = [NSDate date];
                    NSUserDefaults *dataUser = [NSUserDefaults standardUserDefaults];
                    [dataUser setObject:nowDate forKey:@"nowDate"];
                    [dataUser synchronize];
                }
            
        }else{
            [SVProgressHUD showMessage:message];
        }
    } failur:^(NSError *error) {
