计算 star 之间 距离,

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);

}

 

方法一， 

- (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;

float m_width ;

int a = self.tag;

        switch (a) {

            case 0:

                m_width = 0;

                break;

            case 1:

                m_width = 13;

                break;

            case 2:

                m_width = 37;

                break;

            case 3:

                m_width = 50;

                break;

            case 4:

                m_width = 76;

                break;

            case 5:

                m_width = 89;

                break;

            case 6:

                m_width = 116;

                break;

            case 7:

                m_width = 129;

                break;

            case 8:

                m_width = 155;

                break;

            default:

                m_width = 168;

                break;

        }

       self.frame = CGRectMake(m_width + gapToApply , newY, size.width, size.height);

}

 

方法二， 

- (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;

int temp = self.tag % 2;

int index = self.tag / 2;

float margin = 4;

self.frame = CGRectMake(temp * size.width + index*(size.width*2 + margin), 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，
