一，原来的，
- (void)centerIn:(CGRect)_frame with:(int)numberOfStars {
CGSize size = self.frame.size;
float height = self.frame.size.height;
float frameHeight = _frame.size.height;
float newY = (frameHeight-height)/2;
float widthOfStars = self.frame.size.width * numberOfStars + 50;
float frameWidth = _frame.size.width + 15;
float gapToApply = (frameWidth-widthOfStars)/2;
self.frame = CGRectMake(size.width*self.tag + gapToApply , newY, size.width, size.height);
}

上次计算经纬度的时候，脑袋晕了，这次计算间距的时候 又晕了，好吧，必须承认自己很笨，copy 下来留个纪念吧，
补充一个：
NSURLRequest *request = [httpClient requestWithMethod:@"POST" path:FEED_BACK parameters:dic];，post小写的不行，
