要用到的 就是坐标转换方法
- (CGRect)convertRect:(CGRect)rect toView:(**UIView** *)view;
#1:我这里演示的是 tableviewHeader上子view 里的一张图片，将其添加到新的view上，并且 由此图片相对于 手机坐标系的点开始放大（类似于微信朋友圈图片的点击放大）。
#因为是在项目中使用的， 所以只贴出部分代码， 如有需要可联系，Android的 随后更新
(1):获取所需要放大的 图片frame 在 目标视图 _headerView中的 react
CGRect rectInCell = [_headerViewconvertRect:_headerView.headerBgView.frametoView:_headerView];
(2):获取上一步得到的 react 在 tableview 中的 react
CGRect rectInTableView = [_headerViewconvertRect:rectInCelltoView:self.tv];
(3):同上，这样就一步一步的将 所需放大的 图片的 frame 转换到了 相对于屏幕的 位置
CGRect original = [self.tvconvertRect:rectInTableViewtoView:self.view];
#上边三行代码可以用一行来解决
#将_headerView.headerBgView.frame从_headerView转换到当前self.view中，并返回self.view中的位置
CGRect re2 = [self.viewconvertRect:_headerView.headerBgView.framefromView:_headerView];
#放大过程的思路，用一个容器来承载你所需放大的图片（ [.. addsubview] ），然后 [uiview animate…]动画，将图片移动到你所需的位置即可，具体情况根据你的需求来定，此时tableview 上的图片就被你 add到了新的view上边，然后就是点击缩小。
#缩小过程思路
#将第三步计算出的 react 保留下， 因为缩小图片要按照原轨迹返回，点击事件触发 [uiview animate…]动画，将图片缩小到目标大小 （第三步计算结果original），然后动画结束的时候， tableview 的headerview 重新 addsubview 放大的图片。
#swift 代码
func spreadAction() {
if Int(mapView.height) == Int(200 * SCALE_W) {
let rect = self.convertRect(mapView.frame, toView: self.window)
originalFrame = rect
mapView.frame = CGRectMake(originalFrame.origin.x, originalFrame.origin.y, originalFrame.width, originalFrame.height)
self.window?.addSubview(mapView)
#这里动画 换成 uiview.animate{} 就行
let popAnimation = POPSpringAnimation(propertyNamed: kPOPViewFrame)
popAnimation.toValue = NSValue(CGRect: (self.window?.frame)!)
popAnimation.springBounciness = 12.0
popAnimation.springSpeed = 8.0
mapView.pop_addAnimation(popAnimation, forKey: "")
popAnimation.completionBlock = {[weak self] anim, finished in
