地图

从自己的APP跳转到用户本地的APP进行导航。首先，要先查看用户都安装了哪些地图类APP.

下面分3种情况进行分析：

1、用户没有安装第三方的地图，只有苹果自带的地图应用。

2、用户安装一款第三方地图应用。

3、用户安装了超过一款地图应用。

遇到第1、2情况直接跳转应用。第三种情况，需要弹出选项，让用户自主选择。

代码：

//查看线路

- (void)clickLine:(UIButton *)sender{

NSMutableArray *mapArr = [NSMutableArray arrayWithCapacity:0];

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"];

}

if (mapArr.count == 1) {

[self JumpToMap:mapArr[0]];

}else if(mapArr.count > 0){

UIAlertController *mapAlert = [UIAlertController alertControllerWithTitle:nil message:nil preferredStyle:UIAlertControllerStyleActionSheet];

for (NSString *mapName in mapArr) {

UIAlertAction *Action = [UIAlertAction actionWithTitle:mapName style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {

[self JumpToMap:action.title];

}];

[mapAlert addAction:Action];

}

//取消

UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {

}];

[mapAlert addAction:cancelAction];

[self presentViewController:mapAlert animated:YES completion:^{

}];

}else{

//使用自带地图

[self JumpToMap:@"苹果地图"];

}

}

分流函数：

//选择地图

- (void)JumpToMap:(NSString *)mapName{

if ([mapName isEqualToString:@"苹果地图"]) {

[self appleMap];

}else if ([mapName isEqualToString:@"百度地图"]){

[self BaiduMap];

}else if ([mapName isEqualToString:@"高德地图"]){

[self iosMap];

}else if ([mapName isEqualToString:@"腾讯地图"]){

[self qqMap];

}

}

备注：如果兼容ios10以下的应用，跳转请做好适配，ios10以下系统请使用:

- openURL:(NSURL*)url

百度地图

//百度地图

- (void)BaiduMap{

float shopLat = 百度坐标;

float shoplng = 百度坐标;

NSString *urlString = [NSString stringWithFormat:@"baidumap://map/direction?origin=latlng:%f,%f|name:我的位置&mode=transit&coord_type= bd09ll",self.userLocation.location.coordinate.latitude, self.userLocation.location.coordinate.longitude];

if (shopLat != 0 && shoplng != 0) {

urlString = [NSString stringWithFormat:@"%@&destination=latlng:%f,%f|name:%@", urlString, shopLat, shoplng, @"目标地址,你可以自行替换"];

}else{

urlString = [NSString stringWithFormat:@"%@&destination=%@|name:%@",urlString, _orderModel.addressStr,_orderModel.addressStr];

}

urlString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString] options:@{} completionHandler:^(BOOL success) {

}];

}

高德地图

//高德地图

- (void)iosMap{

CLLocationCoordinate2D gcj02Coord = CLLocationCoordinate2DMake(百度坐标, 百度坐标);

float shopLat = gcj02Coord.latitude;

float shoplng = gcj02Coord.longitude;

NSString *urlString = [NSString stringWithFormat:@"iosamap://path?sourceApplication=jikexiue&backScheme=jkxe&slat=%f&slon=%f&sname=我的位置&dev=1&t=1",self.userLocation.location.coordinate.latitude, self.userLocation.location.coordinate.longitude];

if (shopLat != 0 && shoplng != 0) {

urlString = [NSString stringWithFormat:@"%@&dlat=%f&dlon=%f&dname=%@", urlString, shopLat, shoplng ,_orderModel.addressStr];

}else{

urlString = [NSString stringWithFormat:@"%@&dname=%@",urlString, _orderModel.addressStr];

}

urlString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString] options:@{} completionHandler:^(BOOL success) {

}];

}

腾讯地图

//腾讯地图

- (void)qqMap{

CLLocationCoordinate2D gcj02Coord = CLLocationCoordinate2DMake(百度坐标, 百度坐标);

float shopLat = gcj02Coord.latitude;

float shoplng = gcj02Coord.longitude;

NSString *urlString = [NSString stringWithFormat:@"qqmap://map/routeplan?type=bus&fromcoord=%f,%f&from=我的位置&referer=jikexiu",self.userLocation.location.coordinate.latitude, self.userLocation.location.coordinate.longitude];

urlString = [NSString stringWithFormat:@"%@&tocoord=%f,%f&to=%@",urlString, shopLat, shoplng, _orderModel.addressStr];

urlString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString] options:@{} completionHandler:^(BOOL success) {

}];

}

苹果原生地图

1、添加库MapKit.framework

2、引入： #import

//苹果原生地图

- (void)appleMap{

CLLocationCoordinate2D desCoordinate = CLLocationCoordinate2DMake(_orderModel.lat, _orderModel.lng);

MKMapItem *currentLocation = [MKMapItem mapItemForCurrentLocation];

currentLocation.name = @"我的位置";

MKMapItem *toLocation = [[MKMapItem alloc] initWithPlacemark:[[MKPlacemark alloc] initWithCoordinate:desCoordinate addressDictionary:nil]];

toLocation.name = [NSString stringWithFormat:@"%@",_orderModel.addressStr];

[MKMapItem openMapsWithItems:@[currentLocation, toLocation]

launchOptions:@{MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeTransit,MKLaunchOptionsShowsTrafficKey: [NSNumber numberWithBool:YES]}];

}
