iOS 调用地图导航

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 plaincopy

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/"]])

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 plaincopy

- (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

[cpp] view plaincopy

[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

[cpp] view plaincopy

- (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];

}

}
