项目中用到点击店家地址跳到地图导航，app本身没有其他地图相关功能，所以没有必要去集成那些sdk，文件大还很麻烦。直接调用多简单方便，还不用占用自己app。最可贵的是苹果还有自带地图呢
在调用地图之前，先啰嗦一下，由于项目中只返回了店家地址，没有经纬度，所以这里，我要先记录一下，用苹果自带方法，将地址转换成经纬度
1、引入头文件 #import<CoreLocation/CoreLocation.h>
2、声明属性
{
CLGeocoder*_geocoder;
}
@property(nonatomic,assign)CLLocationCoordinate2D coordinate;
3、在你需要调用的地方
_geocoder= [[CLGeocoderalloc]init];
[self getCoordinateByAddress:_address];
#pragma mark根据地名确定地理坐标
-(void)getCoordinateByAddress:(NSString *)address{
//地理编码
[_geocodergeocodeAddressString:addresscompletionHandler:^(NSArray*placemarks,NSError*error) {
//取得第一个地标，地标中存储了详细的地址信息，注意：一个地名可能搜索出多个地址
CLPlacemark*placemark=[placemarksfirstObject];
CLLocation*location=placemark.location;//位置
CLRegion*region=placemark.region;//区域
NSDictionary*addressDic= placemark.addressDictionary;//详细地址信息字典,包含以下部分信息
// NSString *name=placemark.name;//地名
// NSString *thoroughfare=placemark.thoroughfare;//街道
// NSString *subThoroughfare=placemark.subThoroughfare; //街道相关信息，例如门牌等
// NSString *locality=placemark.locality; // 城市
// NSString *subLocality=placemark.subLocality; // 城市相关信息，例如标志性建筑
// NSString *administrativeArea=placemark.administrativeArea; // 州
// NSString *subAdministrativeArea=placemark.subAdministrativeArea; //其他行政区域信息
// NSString *postalCode=placemark.postalCode; //邮编
// NSString *ISOcountryCode=placemark.ISOcountryCode; //国家编码
// NSString *country=placemark.country; //国家
// NSString *inlandWater=placemark.inlandWater; //水源、湖泊
// NSString *ocean=placemark.ocean; // 海洋
// NSArray *areasOfInterest=placemark.areasOfInterest; //关联的或利益相关的地标
NSLog(@"位置:%@,区域:%@,详细信息:%@",location,region,addressDic);
CLLocationDegreeslatitude = location.coordinate.latitude;
CLLocationDegreeslongitude = location.coordinate.longitude;
self.coordinate = CLLocationCoordinate2DMake(latitude,longitude);
NSLog(@"纬度-->%lf,经度-->%lf",latitude,longitude);
//传给接口的纬度和经度
// self->_latitude = [NSString stringWithFormat:@"%lf",latitude];
// self->_longitude = [NSString stringWithFormat:@"%lf",longitude];
}];
}
以上就是先把地址转换成经纬度的过程。
接下来，就是将经纬度传给苹果，高德，百度地图进行跳转导航的过程啦~
1、调用苹果自带地图，记得引用头文件#import<MapKit/MapKit.h>
2、Info.plist文件中加入白名单
高德：iosamap
百度：baidumap
3、代码展示
#pragma mark-- 根据经纬度跳地图导航
-(void)tapAddressAction{
__weaktypeof(self) weakSelf =self;
UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"" message:@"选择地图" preferredStyle:UIAlertControllerStyleActionSheet];
UIAlertAction*action1 = [UIAlertActionactionWithTitle:@"苹果自带地图"style:UIAlertActionStyleDefaulthandler:^(UIAlertAction*_Nonnullaction) {
MKMapItem*currentLocation = [MKMapItemmapItemForCurrentLocation];
MKMapItem *tolocation = [[MKMapItem alloc] initWithPlacemark:[[MKPlacemark alloc] initWithCoordinate:weakSelf.coordinate addressDictionary:nil]];
tolocation.name= weakSelf.address;
[MKMapItem openMapsWithItems:@[currentLocation,tolocation]launchOptions:@{MKLaunchOptionsDirectionsModeKey:MKLaunchOptionsDirectionsModeDriving,
MKLaunchOptionsShowsTrafficKey:[NSNumber numberWithBool:YES]}];
}];
if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"iosamap://"]]) {
UIAlertAction*action2 = [UIAlertActionactionWithTitle:@"高德地图"style:UIAlertActionStyleDefaulthandler:^(UIAlertAction*_Nonnullaction) {
NSString *urlsting =[[NSString stringWithFormat:@"iosamap://navi?sourceApplication= &backScheme= &lat=%f&lon=%f&dev=0&style=2",weakSelf.coordinate.latitude,weakSelf.coordinate.longitude] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlsting]];
}];
[alertaddAction:action2];
}
if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"baidumap://"]]) {
UIAlertAction*action3 = [UIAlertActionactionWithTitle:@"百度地图"style:UIAlertActionStyleDefaulthandler:^(UIAlertAction*_Nonnullaction) {
NSString *urlsting =[[NSString stringWithFormat:@"baidumap://map/direction?origin={{我的位置}}&destination=latlng:%f,%f|name=目的地&mode=driving&coord_type=gcj02",weakSelf.coordinate.latitude,weakSelf.coordinate.longitude] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlsting]];
}];
[alertaddAction:action3];
}
UIAlertAction *action4 = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {
}];
[alertaddAction:action1];
[alertaddAction:action4];
[self.navigationController presentViewController:alert animated:YES completion:nil];
}
我这里会先判断是否安装了高德和百度地图，如果安装了，会在选择弹窗中显示，没安装就不显示，只显示一个苹果自带地图
