CGFloat sinf = sin((endPercentage - startPercentage) * M_PI + startPercentage * M_PI * 2 ) * self.itemSpacing;
CGFloat cosf = cos((endPercentage - startPercentage) * M_PI + startPercentage * M_PI * 2) * self.itemSpacing;

CGPoint center = CGPointMake(CGRectGetMidX(self.bounds) + sinf ,CGRectGetMidY(self.bounds) - cosf);

大意就是通过改变中心点的位置修改item的位置
