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

[cpp]  view plain copy

1. CLLocationCoordinate2D startCoor = self.mapView.userLocation.location.coordinate;  
2. CLLocationCoordinate2D endCoor = CLLocationCoordinate2DMake(startCoor.latitude+0.01, startCoor.longitude+0.01);  
3.   
4. if (SYSTEM_VERSION_LESS_THAN(@"6.0")) { // ios6以下，调用google map  
5.       
6.     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];  
7.     //        @"http://maps.apple.com/?saddr=%f,%f&daddr=%f,%f",startCoor.latitude,startCoor.longitude,endCoor.latitude,endCoor.longitude  
8.     urlString =  [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];  
9.     NSURL *aURL = [NSURL URLWithString:urlString];  
10.     [[UIApplication sharedApplication] openURL:aURL];  
11. } else { // 直接调用ios自己带的apple map  
12.       
13.     MKMapItem *currentLocation = [MKMapItem mapItemForCurrentLocation];  
14.     MKMapItem *toLocation = [[MKMapItem alloc] initWithPlacemark:[[MKPlacemark alloc] initWithCoordinate:endCoor addressDictionary:nil]];  
15.     toLocation.name = @"to name";  
16.       
17.     [MKMapItem openMapsWithItems:@[currentLocation, toLocation]  
18.                    launchOptions:@{MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeDriving,MKLaunchOptionsShowsTrafficKey: [NSNumber numberWithBool:YES]}];  
19.       
20. }  

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/"]])

参考

高德地图：

 

if ([[UIApplicationsharedApplication]canOpenURL:[NSURLURLWithString:@"iosamap://"]])

参考

Google Maps：

 

if ([[UIApplicationsharedApplication]canOpenURL:[NSURLURLWithString:@"comgooglemaps://"]])

参考

示例代码

 

[cpp]  view plain copy

1. - (void)availableMapsApps {  
2.     [self.availableMaps removeAllObjects];  
3.       
4.     CLLocationCoordinate2D startCoor = self.mapView.userLocation.location.coordinate;  
5.     CLLocationCoordinate2D endCoor = CLLocationCoordinate2DMake(startCoor.latitude+0.01, startCoor.longitude+0.01);  
6.     NSString *toName = @"to name";  
7.       
8.     if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"baidumap://map/"]]){  
9.         NSString *urlString = [NSString stringWithFormat:@"baidumap://map/direction?origin=latlng:%f,%f|name:我的位置&destination=latlng:%f,%f|name:%@&mode=transit",  
10.                                startCoor.latitude, startCoor.longitude, endCoor.latitude, endCoor.longitude, toName];  
11.           
12.         NSDictionary *dic = @{@"name": @"百度地图",  
13.                               @"url": urlString};  
14.         [self.availableMaps addObject:dic];  
15.     }  
16.     if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"iosamap://"]]) {  
17.         NSString *urlString = [NSString stringWithFormat:@"iosamap://navi?sourceApplication=%@&backScheme=applicationScheme&poiname=fangheng&poiid=BGVIS&lat=%f&lon=%f&dev=0&style=3",  
18.                                @"云华时代", endCoor.latitude, endCoor.longitude];  
19.           
20.         NSDictionary *dic = @{@"name": @"高德地图",  
21.                               @"url": urlString};  
22.         [self.availableMaps addObject:dic];  
23.     }  
24.     if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"comgooglemaps://"]]) {  
25.         NSString *urlString = [NSString stringWithFormat:@"comgooglemaps://?saddr=&daddr=%f,%f?er=%f,%f&directionsmode=transit", endCoor.latitude, endCoor.longitude, startCoor.latitude, startCoor.longitude];  
26.           
27.         NSDictionary *dic = @{@"name": @"Google Maps",  
28.                               @"url": urlString};  
29.         [self.availableMaps addObject:dic];  
30.     }  
31. }  

显示一个ActionSheet

 

[cpp]  view plain copy

1. [self availableMapsApps];  
2.     UIActionSheet *action = [[UIActionSheet alloc] init];  
3.       
4.     [action addButtonWithTitle:@"使用系统自带地图导航"];  
5.     for (NSDictionary *dic in self.availableMaps) {  
6.         [action addButtonWithTitle:[NSString stringWithFormat:@"使用%@导航", dic[@"name"]]];  
7.     }  
8.     [action addButtonWithTitle:@"取消"];  
9.     action.cancelButtonIndex = self.availableMaps.count + 1;  
10.     action.delegate = self;  
11.     [action showInView:self.view];  

实现delegate

 

 

[cpp]  view plain copy

1. - (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {  
2.     if (buttonIndex == 0) {  
3.         CLLocationCoordinate2D startCoor = self.mapView.userLocation.location.coordinate;  
4.         CLLocationCoordinate2D endCoor = CLLocationCoordinate2DMake(startCoor.latitude+0.01, startCoor.longitude+0.01);  
5.           
6.         if (SYSTEM_VERSION_LESS_THAN(@"6.0")) { // ios6以下，调用google map  
7.               
8.             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];  
9.             //        @"http://maps.apple.com/?saddr=%f,%f&daddr=%f,%f",startCoor.latitude,startCoor.longitude,endCoor.latitude,endCoor.longitude  
10.             urlString =  [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];  
11.             NSURL *aURL = [NSURL URLWithString:urlString];  
12.             [[UIApplication sharedApplication] openURL:aURL];  
13.         } else{// 直接调用ios自己带的apple map  
14.               
15.             MKMapItem *currentLocation = [MKMapItem mapItemForCurrentLocation];  
16.             MKPlacemark *placemark = [[MKPlacemark alloc] initWithCoordinate:endCoor addressDictionary:nil];  
17.             MKMapItem *toLocation = [[MKMapItem alloc] initWithPlacemark:placemark];  
18.             toLocation.name = @"to name";  
19.               
20.             [MKMapItem openMapsWithItems:@[currentLocation, toLocation]  
21.                            launchOptions:@{MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeDriving,MKLaunchOptionsShowsTrafficKey: [NSNumber numberWithBool:YES]}];  
22.               
23.         }  
24.     }else if (buttonIndex < self.availableMaps.count+1) {  
25.         NSDictionary *mapDic = self.availableMaps[buttonIndex-1];  
26.         NSString *urlString = mapDic[@"url"];  
27.         urlString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];  
28.         NSURL *url = [NSURL URLWithString:urlString];  
29.         DEBUG_LOG(@"\n%@\n%@\n%@", mapDic[@"name"], mapDic[@"url"], urlString);  
30.         [[UIApplication sharedApplication] openURL:url];  
31.     }  
32. }
