2 自定义地图样式
控制器初始化时，设置地图样式，之后可随时控制打开/关闭个性化
+ (void)initialize {
//设置自定义地图样式，会影响所有地图实例
//注：必须在BMKMapView对象初始化之前调用
NSString* path = [[NSBundle mainBundle] pathForResource:@"custom_config_清新蓝" ofType:@""];
[BMKMapView customMapStyle:path];
}
//打开/关闭个性化地图
[BMKMapView enableCustomMapStyle:YES];
custom_config_清新蓝 样式文件：
[

"featureType": "land",
"elementType": "geometry",

3 手势
3.1 系统手势
地图手势通过 mapView 的代理 BMKMapViewDelegate 的代理方法回调
- 点中底图标注后会回调此接口
- (void)mapView:(BMKMapView *)mapView onClickedMapPoi:(BMKMapPoi*)mapPoi
{
NSLog(@"onClickedMapPoi-%@",mapPoi.text);
NSString* showmeg = [NSString stringWithFormat:@"您点击了底图标注:%@,\r\n当前经度:%f,当前纬度:%f,\r\nZoomLevel=%d;RotateAngle=%d;OverlookAngle=%d", mapPoi.text,mapPoi.pt.longitude,mapPoi.pt.latitude, (int)_mapView.zoomLevel,_mapView.rotation,_mapView.overlooking];
_showMsgLabel.text = showmeg;
}
- 点中底图空白处会回调此接口
- (void)mapView:(BMKMapView *)mapView onClickedMapBlank:(CLLocationCoordinate2D)coordinate
{
NSLog(@"onClickedMapBlank-latitude==%f,longitude==%f",coordinate.latitude,coordinate.longitude);
NSString* showmeg = [NSString stringWithFormat:@"您点击了地图空白处(blank click).\r\n当前经度:%f,当前纬度:%f,\r\nZoomLevel=%d;RotateAngle=%d;OverlookAngle=%d", coordinate.longitude,coordinate.latitude,
(int)_mapView.zoomLevel,_mapView.rotation,_mapView.overlooking];
_showMsgLabel.text = showmeg;
}
- 双击地图时会回调此接口
- (void)mapview:(BMKMapView *)mapView onDoubleClick:(CLLocationCoordinate2D)coordinate
{
NSLog(@"onDoubleClick-latitude==%f,longitude==%f",coordinate.latitude,coordinate.longitude);
NSString* showmeg = [NSString stringWithFormat:@"您双击了地图(double click).\r\n当前经度:%f,当前纬度:%f,\r\nZoomLevel=%d;RotateAngle=%d;OverlookAngle=%d", coordinate.longitude,coordinate.latitude,
(int)_mapView.zoomLevel,_mapView.rotation,_mapView.overlooking];
_showMsgLabel.text = showmeg;
}
- 长按地图时会回调此接口
- (void)mapview:(BMKMapView *)mapView onLongClick:(CLLocationCoordinate2D)coordinate
{
NSLog(@"onLongClick-latitude==%f,longitude==%f",coordinate.latitude,coordinate.longitude);
NSString* showmeg = [NSString stringWithFormat:@"您长按了地图(long pressed).\r\n当前经度:%f,当前纬度:%f,\r\nZoomLevel=%d;RotateAngle=%d;OverlookAngle=%d", coordinate.longitude,coordinate.latitude,
(int)_mapView.zoomLevel,_mapView.rotation,_mapView.overlooking];
_showMsgLabel.text = showmeg;
}
- 地图展示区域发生变化
- (void)mapView:(BMKMapView *)mapView regionDidChangeAnimated:(BOOL)animated
{
NSString* showmeg = [NSString stringWithFormat:@"地图区域发生了变化(x=%d,y=%d,\r\nwidth=%d,height=%d).\r\nZoomLevel=%d;RotateAngle=%d;OverlookAngle=%d",(int)_mapView.visibleMapRect.origin.x,(int)_mapView.visibleMapRect.origin.y,(int)_mapView.visibleMapRect.size.width,(int)_mapView.visibleMapRect.size.height,(int)_mapView.zoomLevel,_mapView.rotation,_mapView.overlooking];
_showMsgLabel.text = showmeg;
}
3.2 自定义手势
- (void)addCustomGestures {
/*
*注意：
*添加自定义手势时，必须设置UIGestureRecognizer的属性cancelsTouchesInView 和 delaysTouchesEnded 为NO,
*否则影响地图内部的手势处理
*/
UITapGestureRecognizer *doubleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleDoubleTap:)];
doubleTap.delegate = self;
doubleTap.numberOfTapsRequired = 2;
doubleTap.cancelsTouchesInView = NO;
doubleTap.delaysTouchesEnded = NO;
[self.view addGestureRecognizer:doubleTap];
/*
*注意：
*添加自定义手势时，必须设置UIGestureRecognizer的属性cancelsTouchesInView 和 delaysTouchesEnded 为NO,
*否则影响地图内部的手势处理
*/
UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];
singleTap.delegate = self;
singleTap.cancelsTouchesInView = NO;
singleTap.delaysTouchesEnded = NO;
[singleTap requireGestureRecognizerToFail:doubleTap];
[self.view addGestureRecognizer:singleTap];
}
- (void)handleSingleTap:(UITapGestureRecognizer *)theSingleTap {
/*
*do something
*/
NSLog(@"my handleSingleTap");
}
- (void)handleDoubleTap:(UITapGestureRecognizer *)theDoubleTap {
/*
*do something
*/
NSLog(@"my handleDoubleTap");
}
4 地图截图并保存
//截图
-(void)snapshot
_imgView.image = [_mapView takeSnapshot];
[self saveImageToPhotos:_imgView.image];
}
- (void)saveImageToPhotos:(UIImage*)savedImage
{
UIImageWriteToSavedPhotosAlbum(savedImage,self,@selector(image:didFinishSavingWithError:contextInfo:),NULL);
}
// 指定回调方法
- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo {
NSString *msg = nil ;
if(error != nil && image != nil) {
msg = @"保存图片失败" ;
} else {
msg = @"保存图片成功" ;
}
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"保存图片结果提示"
message:msg
delegate:self
cancelButtonTitle:@"确定"
otherButtonTitles:nil];
[alert show];
}
