在调地图之前，先了解下不同地图使用的坐标系
API 坐标系
百度地图API 百度坐标
腾讯搜搜地图API 火星坐标
搜狐搜狗地图API 搜狗坐标
阿里云地图API 火星坐标
图吧MapBar地图API 图吧坐标
高德MapABC地图API 火星坐标
灵图51ditu地图API 火星坐标
openURL打开地图
打开本地地图，看用户安装了哪些地图APP
已经安装的，弹窗选择。没有安装，就调起苹果地图。
NSMutableArray *mapArr = [[NSMutableArray alloc]init];
if([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"baidumap://"]]){
[mapArr addObject:@"百度地图"];
}
if([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"iosamap://"]]){
[mapArr addObject:@"高德地图"];
}
if([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"qqmap://"]]){
[mapArr addObject:@"腾讯地图"];
}
[mapArr addObject:@"苹果地图"];
if (mapArr.count == 1) {
[self jumpToMap:mapArr[0]];
}
KWeakSelf(self);
WMZDialog *alert = Dialog();

}
- (void)jumpToMap:(NSString *)mapName{
if ([mapName isEqualToString:@"高德地图"])//高德地图
{
[self openMapGaoDe];
}
else if ([mapName isEqualToString:@"百度地图"])//百度地图
{
[self openMapBaiDu];
}
else if ([mapName isEqualToString:@"腾讯地图"])//腾讯地图
{
[self openMapQQ];
}

{
[self openMapApple];
}
}
百度地图
注意：我定位使用的是腾讯定位。腾讯用的是火星坐标 ，而百度用的是百度坐标 使用的时候需要转化
//百度地图
- (void)openMapBaiDu{
CLLocation *coor = [[CLLocation alloc]initWithLatitude:[self.model.lat doubleValue] longitude:[self.model.lng doubleValue]];
// 转为百度经纬度类型的坐标
CLLocation *location = [coor locationBaiduFromMars];
NSString *urlStr = [[NSString stringWithFormat:@"baidumap://map/direction?origin={{我的位置}}&destination=name:%@|latlng:%f,%f&coord_type=bd09ll&mode=walking&src=ios.wkbb.%@",self.model.simple_name,location.coordinate.latitude,location.coordinate.longitude,APP_NAME] stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLFragmentAllowedCharacterSet]];
[[UIApplication sharedApplication]openURL:[NSURL URLWithString:urlStr] options:@{} completionHandler:^(BOOL success) {
}];
高德地图
//高德地图
- (void)openMapGaoDe{
NSString *urlStr = [[NSString stringWithFormat:@"iosamap://path?sourceApplication=APPName&sid=&slat=&slon=&sname=我的位置&did=&dlat=%@&dlon=%@&dname=%@&dev=0&t=0",self.model.lat,self.model.lng,self.model.simple_name] stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLFragmentAllowedCharacterSet]];
if (@available(iOS 10.0, *)) {
[[UIApplication sharedApplication]openURL:[NSURL URLWithString:urlStr] options:@{} completionHandler:^(BOOL success) {
}];
} else {
// Fallback on earlier versions
[[UIApplication sharedApplication]openURL:[NSURL URLWithString:urlStr]];
}
}
腾讯地图
NSString *urlStr = [[NSString stringWithFormat:@"qqmap://map/routeplan?type=drive&from=我的位置&fromcoord=&to=%@&tocoord=%@,%@&referer=%@",self.model.simple_name,self.model.lat,self.model.lng,@"腾讯key"] stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLFragmentAllowedCharacterSet]];
if (@available(iOS 10.0, *)) {
[[UIApplication sharedApplication]openURL:[NSURL URLWithString:urlStr] options:@{} completionHandler:^(BOOL success) {
}];
} else {
// Fallback on earlier versions
[[UIApplication sharedApplication]openURL:[NSURL URLWithString:urlStr]];
}
苹果地图
1、添加库MapKit.framework
2、引入： #import <MapKit/MapKit.h>
//苹果地图
- (void)openMapApple{
//终点坐标
CLLocationCoordinate2D desCoordinate = CLLocationCoordinate2DMake([self.model.lat doubleValue], [self.model.lng doubleValue]);
//用户位置
MKMapItem *currentLocation = [MKMapItem mapItemForCurrentLocation];
currentLocation.name = @"我的位置";
//终点位置
MKMapItem *toLocation = [[MKMapItem alloc] initWithPlacemark:[[MKPlacemark alloc] initWithCoordinate:desCoordinate addressDictionary:nil]];
toLocation.name = self.model.address;
[MKMapItem openMapsWithItems:@[currentLocation, toLocation]
launchOptions:@{MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeTransit,MKLaunchOptionsShowsTrafficKey: [NSNumber numberWithBool:YES]}];
}
不同坐标转化
新建一个CLLocation的类别
CLLocation+JRLocation.h
// 火星坐标系转换扩展
/*
从 CLLocationManager 取出来的经纬度放到 mapView 上显示，是错误的!
从 CLLocationManager 取出来的经纬度去 Google Maps API 做逆地址解析，当然是错的！
从 MKMapView 取出来的经纬度去 Google Maps API 做逆地址解析终于对了。去百度地图API做逆地址解析，依旧是错的！
从上面两处取的经纬度放到百度地图上显示都是错的！错的！的！
分为 地球坐标，火星坐标（iOS mapView 高德 ， 国内google ,搜搜、阿里云 都是火星坐标），百度坐标(百度地图数据主要都是四维图新提供的)
火星坐标: MKMapView
地球坐标: CLLocationManager
当用到CLLocationManager 得到的数据转化为火星坐标, MKMapView不用处理
