iOS开发——项目中的地图跳转（苹果地图 百度地图 高德地图）

最近项目中遇到一个小需求，就是点击地图上的大头针进行导航，如果手机中装了多种地图软件，就用提示框显示出来，如果没有装地图软件，就默认跳转到苹果自带的地图进行导航，代码如下：

//导航按钮- (void)guideBtnAction:(UIButton *)button{//创建时不指定按钮UIActionSheet *sheet = [[UIActionSheet alloc]initWithTitle:nil delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil, nil];NSArray *mapArray = @[@"/",@"baidumap://map/",@"iosamap://"];NSArray *mapNameArray = @[@"苹果地图",@"百度地图",@"高德地图"];for (int i = 0; i < 3; i ++) {if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:mapArray[i]]]) {[sheet addButtonWithTitle:mapNameArray[i]];}}//添加取消按钮[sheet addButtonWithTitle:@"取消"];sheet.delegate = self;sheet.cancelButtonIndex = sheet.numberOfButtons - 1;[sheet showInView:self.view.window];}

接下来是响应提示框的按钮事件：

#pragma mark - UIActionSheetDelegate- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{if (buttonIndex == actionSheet.cancelButtonIndex) {[actionSheet dismissWithClickedButtonIndex:actionSheet.numberOfButtons - 1 animated:YES];return;}if (actionSheet.numberOfButtons == 4) {switch (buttonIndex) {case 0:[self openNativeAppleMapWithTag];break;case 1:[self openNativeNaviBaiDu];break;case 2:[self openNativiGaoDe];break;default:break;}}else if (actionSheet.numberOfButtons == 3){switch (buttonIndex) {case 0:[self openNativeAppleMapWithTag];break;case 1:{if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"iosamap://"]]) {[self openNativiGaoDe];}if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"baidumap://map/"]]) {[self openNativeNaviBaiDu];}}break;default:break;}}else{switch (buttonIndex) {case 0:[self openNativeAppleMapWithTag];break;default:break;}}}//调用高德地图客户端- (void)openNativiGaoDe{//起点CLLocation *location = [[CLLocation alloc]initWithLatitude:[_latitude floatValue] longitude:[_longitude floatValue]];CLLocationCoordinate2D coor = location.coordinate;//终点CLLocation *location2 = [[CLLocation alloc]initWithLatitude:[self.pointModel.lat floatValue] longitude:[self.pointModel.lng floatValue]];CLLocationCoordinate2D coor2 = location2.coordinate;NSString *url = [[NSString stringWithFormat:@"iosamap://path?sourceApplication=applicationName&sid=BGVIS1&slat=%lf&slon=%lf&sname=我的位置&did=BGVIS2&dlat=%lf&dlon=%lf&dname=%@&dev=0&m=0",coor.latitude,coor.longitude, coor2.latitude - 0.00328,coor2.longitude - 0.01185,self.pointModel.stationname] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];[[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];}//调用百度地图客户端导航- (void)openNativeNaviBaiDu{NSString *baiduParameterFormat = @"baidumap://map/direction?origin=latlng:%f,%f|name:我的位置&destination=latlng:%f,%f|name:终点&mode=driving";NSString *urlString = [[NSString stringWithFormat:baiduParameterFormat,[_latitude floatValue],[_longitude floatValue],[self.pointModel.lat floatValue],[self.pointModel.lng floatValue]]stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];[[UIApplication sharedApplication]openURL:[NSURL URLWithString:urlString]];}//调用苹果地图- (void)openNativeAppleMapWithTag{//起点MKMapItem *currentLocation = [MKMapItem mapItemForCurrentLocation];;CLLocationCoordinate2D desCorrdinate = CLLocationCoordinate2DMake([self.pointModel.lat floatValue] - 0.00328, [self.pointModel.lng floatValue] - 0.01185);//终点MKMapItem *toLocation = [[MKMapItem alloc] initWithPlacemark:[[MKPlacemark alloc] initWithCoordinate:desCorrdinate addressDictionary:nil]];toLocation.name = [NSString stringWithFormat:@"%@",self.pointModel.stationname];//默认驾车[MKMapItem openMapsWithItems:@[currentLocation,toLocation] launchOptions:@{MKLaunchOptionsDirectionsModeKey:MKLaunchOptionsDirectionsModeDriving,MKLaunchOptionsShowsTrafficKey:[NSNumber numberWithBool:YES]}];}
