最近在寫百度地圖的時候發現地圖和scrollView和tableView的滑動手勢會沖突，這里以百度地圖作為示例寫一遍解決方法

首先遵循UIGestureRecognizerDelegate代理方法

然后在你需要禁止滑動的scrollView添加手勢

// 給第一個tableView添加手勢
UIGestureRecognizer *mainScrollVTap = [[UIGestureRecognizer alloc]init];
mainScrollVTap.delegate=self;
[scroAll addGestureRecognizer:mainScrollVTap];

// 給最底部的scrollview 添加手勢
UIGestureRecognizer *mainScrollVTap = [[UIGestureRecognizer alloc]init];
mainScrollVTap.delegate=self;
[scroAll addGestureRecognizer:mainScrollVTap];

在地圖上添加點擊手勢

_mapView = [[BMKMapView alloc]initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, PTTotalHeight/5*2)];
_mapView.userTrackingMode = BMKUserTrackingModeFollow;//設置定位的狀態
_mapView.delegate = self;
_mapView.showsUserLocation = YES;//顯示定位圖層
[scroRoute addSubview:_mapView];
//給地圖加手勢以解決滑動沖突
UITapGestureRecognizer *provinceMapTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(provinceMapTapped)];
provinceMapTap.delegate = self;
[_mapView addGestureRecognizer:provinceMapTap];

最后實現手勢代理方法判斷出需要觸發哪一個手勢

#pragma mark 手勢代理方法 ，判斷觸摸的是地圖還是外層的view
-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch{
    //判斷如果是百度地圖的view 既可以實現手勢拖動 scrollview 的滾動關閉
    if ([gestureRecognizer.view isKindOfClass:[BMKMapView class]] ){
        scroAll.scrollEnabled = NO;
        scroRoute.scrollEnabled = NO;
        return YES;
    }else{
        scroAll.scrollEnabled = YES;
        scroRoute.scrollEnabled = YES;
        return NO;
    }
}

需要注意的一點是給地圖添加了點擊手勢需要實現方法，不然會崩潰

-(void)provinceMapTapped{
}

順便整理一下如何判斷scrollView的滑動方向

聲明變量

@interface ViewController ()<UIScrollViewDelegate>
{
    UIScrollView *scro;
    float lastContentOffsetX;
    float lastContentOffsetY;
}

在scrollViewWillBeginDragging方法里記錄開始前的X、Y值

-(void)scrollViewWillBeginDragging:(UIScrollView *)scrollView {
    lastContentOffsetY = scrollView.contentOffset.y;
    lastContentOffsetX = scrollView.contentOffset.x;
}

在scrollViewDidScroll方法里判斷滑動方向

-(void)scrollViewDidScroll:(UIScrollView *)scrollView {
    if(scrollView.contentOffset.y>lastContentOffsetY){
        NSLog(@"向上滑動");
    }else if(scrollView.contentOffset.y<lastContentOffsetY){
        NSLog(@"向下滑動");
    }
    if(scrollView.contentOffset.x<lastContentOffsetX){
        NSLog(@"向左滑動");
    }else if(scrollView.contentOffset.x>lastContentOffsetX){
        NSLog(@"向右滑動");
    }
}
