iOS开发----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/"]])

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

- (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];
}
}
