设置map旋转缩放中心点，当手势操作时，设置map中心的为两指中心点

#pragma mark - 实时跟新地图手势中心点
- (void)recognizerUPdate:(id) recognizera andType:(int)type
{
    UIPinchGestureRecognizer *recognizer;
    if (type==1){
        recognizer = recognizera;
    }else{
        recognizer = recognizera;
    }
    if (recognizer.numberOfTouches==2) {
        CGPoint onoPoint = [recognizer locationOfTouch:0 inView:recognizer.view];
        CGPoint twoPoint = [recognizer locationOfTouch:1 inView:recognizer.view];
        CGPoint anchorPoint;
        anchorPoint.x = (onoPoint.x + twoPoint.x) / 2 / recognizer.view.bounds.size.width;
        anchorPoint.y = (onoPoint.y + twoPoint.y) / 2 / recognizer.view.bounds.size.height;
        [self setAnchorPoint:anchorPoint forView:recognizer.view];
    }
}
#pragma mark - 设立旋转中心点
- (void)setDefaultAnchorPointforView:(UIView *)view
{
    [self setAnchorPoint:CGPointMake(0.5f, 0.5f) forView:view];
}

#pragma mark -旋转中心点计算
- (void)setAnchorPoint:(CGPoint)anchorPoint forView:(UIView *)view
{
    CGPoint oldOrigin      = view.frame.origin;
    view.layer.anchorPoint = anchorPoint;
    CGPoint newOrigin      = view.frame.origin;
    CGPoint transition;
    transition.x = newOrigin.x - oldOrigin.x;
    transition.y = newOrigin.y - oldOrigin.y;
    view.center = CGPointMake (view.center.x - transition.x, view.center.y - transition.y);
}

多手势支持（同时支持旋转缩放）

//设置多手势支持
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer: (UIGestureRecognizer *)otherGestureRecognizer
{
    return YES;
}

效果如下：
