在该方法的起始插入以下代码:

-(void)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 

dispatch_async(dispatch_queue_create("APP_EXPIRE_KILL", 0), ^{
    // 检查程序是否过期
    NSTimeInterval now = [[NSDate date] timeIntervalSince1970];
    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    [formatter setDateFormat:@"MMM d yyyy"];
    [formatter setLocale:[[NSLocale alloc] initWithLocaleIdentifier:@"en_US"]];
    NSDate *expiresDate = [formatter dateFromString:[NSString stringWithFormat:@"%s", __DATE__]];
 
    // 一周过期
    if (now - [expiresDate timeIntervalSince1970] >= 7*24*3600) {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"您使用的程序是测试版本,目前已经过期,请更新到最新版本"
                                                        message:nil
                                                       delegate:self
                                              cancelButtonTitle:@"确定"
                                              otherButtonTitles:nil];
        [alert performSelectorOnMainThread:@selector(show) withObject:nil waitUntilDone:NO];
 
        sleep(10);
        kill(getpid(), 9);
    }
});
