描述

TextureMapView

getMap()

获取地图控制器

ViewPager

onPageSelected(int position)

viewPage选中回调

ViewPager

canScroll(View v, boolean checkV, int dx, int x, int y)

用于判断viewPage页面是否可以切换

核心代码

1.判断viewPage是否可以切换

JAVA

protected boolean canScroll(View v, boolean checkV, int dx, int x, int y) {
    if (Math.abs(dx) > 30) {
        return super.canScroll(v, checkV, dx, x, y);
    } else {
        return true;
    }
}

BMKShotView

- (instancetype)init;

多个地图创建

UIPanGestureRecognizer

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer;

支持多种手势同时识别

核心代码

1.设置支持多手势同时识别

Objective-C

//多手势同时识别
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
    return YES;
}

2.处理新添加的手势的事件处理

Objective-C

- (void)panHandler:(UIPanGestureRecognizer *)gesture {
    // 当速度大于某个值时触发page切换
    if (fabs([gesture velocityInView:self.scrollView].x) > 2300)
    {
        // -1：左滑，1：右滑
        NSInteger direction = fabs([gesture velocityInView:self.scrollView].x) / [gesture velocityInView:self.scrollView].x;
        NSInteger index = self.currentIndex - direction;

        if (index >= 0 && index <= 2 &&!self.scrollView.isDecelerating)
        {
            CGFloat width = self.scrollView.frame.size.width * index;
            [self.scrollView setContentOffset:CGPointMake(width, 0) animated:YES];
        }
    }
}
