iOS 调用地图导航
注意:本文章下的代码有个别变量未知,所以是不能直接跑通的,我也是转别人的
在IOS6.0系统后,兼容iOS5.0与iOS6.0地图导航,需要分两个步骤
#define SYSTEM_VERSION_LESS_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)//用来获取手机的系统,判断系统是多少
- CLLocationCoordinate2D startCoor = self.mapView.userLocation.location.coordinate;
- CLLocationCoordinate2D endCoor = CLLocationCoordinate2DMake(startCoor.latitude+0.01, startCoor.longitude+0.01);
- if (SYSTEM_VERSION_LESS_THAN(@"6.0")) { // ios6以下,调用google map
- NSString *urlString = [[NSString alloc] initWithFormat:@"http://maps.google.com/maps?saddr=%f,%f&daddr=%f,%f&dirfl=d",startCoor.latitude,startCoor.longitude,endCoor.latitude,endCoor.longitude];
- // @"http://maps.apple.com/?saddr=%f,%f&daddr=%f,%f",startCoor.latitude,startCoor.longitude,endCoor.latitude,endCoor.longitude
- urlString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
- NSURL *aURL = [NSURL URLWithString:urlString];
- [[UIApplication sharedApplication] openURL:aURL];
- } else { // 直接调用ios自己带的apple map
- MKMapItem *currentLocation = [MKMapItem mapItemForCurrentLocation];
- MKMapItem *toLocation = [[MKMapItem alloc] initWithPlacemark:[[MKPlacemark alloc] initWithCoordinate:endCoor addressDictionary:nil]];
- toLocation.name = @"to name";
- [MKMapItem openMapsWithItems:@[currentLocation, toLocation]
- launchOptions:@{MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeDriving,MKLaunchOptionsShowsTrafficKey: [NSNumber numberWithBool:YES]}];
- }
如果不想使用苹果自带的地图的话,也可以使用第三方的地图,如百度、Google Maps、高德等
使用前,先判断设备上是否已安装应用
百度地图:
if ([[UIApplicationsharedApplication]canOpenURL:[NSURLURLWithString:@"baidumap://map/"]])
高德地图:
if ([[UIApplicationsharedApplication]canOpenURL:[NSURLURLWithString:@"iosamap://"]])
Google Maps:
if ([[UIApplicationsharedApplication]canOpenURL:[NSURLURLWithString:@"comgooglemaps://"]])
示例代码
- - (void)availableMapsApps {
- [self.availableMaps removeAllObjects];
- CLLocationCoordinate2D startCoor = self.mapView.userLocation.location.coordinate;
- CLLocationCoordinate2D endCoor = CLLocationCoordinate2DMake(startCoor.latitude+0.01, startCoor.longitude+0.01);
- NSString *toName = @"to name";
- if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"baidumap://map/"]]){
- NSString *urlString = [NSString stringWithFormat:@"baidumap://map/direction?origin=latlng:%f,%f|name:我的位置&destination=latlng:%f,%f|name:%@&mode=transit",
- startCoor.latitude, startCoor.longitude, endCoor.latitude, endCoor.longitude, toName];
- NSDictionary *dic = @{@"name": @"百度地图",
- @"url": urlString};
- [self.availableMaps addObject:dic];
- }
- if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"iosamap://"]]) {
- NSString *urlString = [NSString stringWithFormat:@"iosamap://navi?sourceApplication=%@&backScheme=applicationScheme&poiname=fangheng&poiid=BGVIS&lat=%f&lon=%f&dev=0&style=3",
- @"云华时代", endCoor.latitude, endCoor.longitude];
- NSDictionary *dic = @{@"name": @"高德地图",
- @"url": urlString};
- [self.availableMaps addObject:dic];
- }
- if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"comgooglemaps://"]]) {
- NSString *urlString = [NSString stringWithFormat:@"comgooglemaps://?saddr=&daddr=%f,%f¢er=%f,%f&directionsmode=transit", endCoor.latitude, endCoor.longitude, startCoor.latitude, startCoor.longitude];
- NSDictionary *dic = @{@"name": @"Google Maps",
- @"url": urlString};
- [self.availableMaps addObject:dic];
- }
- }
显示一个ActionSheet
- [self availableMapsApps];
- UIActionSheet *action = [[UIActionSheet alloc] init];
- [action addButtonWithTitle:@"使用系统自带地图导航"];
- for (NSDictionary *dic in self.availableMaps) {
- [action addButtonWithTitle:[NSString stringWithFormat:@"使用%@导航", dic[@"name"]]];
- }
- [action addButtonWithTitle:@"取消"];
- action.cancelButtonIndex = self.availableMaps.count + 1;
- action.delegate = self;
- [action showInView:self.view];
实现delegate
- - (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
- if (buttonIndex == 0) {
- CLLocationCoordinate2D startCoor = self.mapView.userLocation.location.coordinate;
- CLLocationCoordinate2D endCoor = CLLocationCoordinate2DMake(startCoor.latitude+0.01, startCoor.longitude+0.01);
- if (SYSTEM_VERSION_LESS_THAN(@"6.0")) { // ios6以下,调用google map
- NSString *urlString = [[NSString alloc] initWithFormat:@"http://maps.google.com/maps?saddr=%f,%f&daddr=%f,%f&dirfl=d",startCoor.latitude,startCoor.longitude,endCoor.latitude,endCoor.longitude];
- // @"http://maps.apple.com/?saddr=%f,%f&daddr=%f,%f",startCoor.latitude,startCoor.longitude,endCoor.latitude,endCoor.longitude
- urlString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
- NSURL *aURL = [NSURL URLWithString:urlString];
- [[UIApplication sharedApplication] openURL:aURL];
- } else{// 直接调用ios自己带的apple map
- MKMapItem *currentLocation = [MKMapItem mapItemForCurrentLocation];
- MKPlacemark *placemark = [[MKPlacemark alloc] initWithCoordinate:endCoor addressDictionary:nil];
- MKMapItem *toLocation = [[MKMapItem alloc] initWithPlacemark:placemark];
- toLocation.name = @"to name";
- [MKMapItem openMapsWithItems:@[currentLocation, toLocation]
- launchOptions:@{MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeDriving,MKLaunchOptionsShowsTrafficKey: [NSNumber numberWithBool:YES]}];
- }
- }else if (buttonIndex < self.availableMaps.count+1) {
- NSDictionary *mapDic = self.availableMaps[buttonIndex-1];
- NSString *urlString = mapDic[@"url"];
- urlString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
- NSURL *url = [NSURL URLWithString:urlString];
- DEBUG_LOG(@"\n%@\n%@\n%@", mapDic[@"name"], mapDic[@"url"], urlString);
- [[UIApplication sharedApplication] openURL:url];
- }
- }
