iOS App內(nèi)部調(diào)起百度地圖、高德地圖、騰訊地圖

公司App集成的是百度地圖,然后調(diào)起百度地圖、高德地圖、騰訊地圖、蘋(píng)果地圖進(jìn)行導(dǎo)航的功能.

一.首先需要在info.plist文件中添加白名單如下:
<key>LSApplicationQueriesSchemes</key>
    <array>
        <string>baidumap</string> //百度
        <string>iosamap</string> //高德
        <string>qqmap</string> //騰訊
    </array>

使用: [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"白名單://"]] 判斷是否安裝白名單里面的App.

二.由于項(xiàng)目繼承的是百度地圖,調(diào)用其他導(dǎo)航會(huì)有地理偏差,我們要進(jìn)行坐標(biāo)轉(zhuǎn)換,可以使用這個(gè)轉(zhuǎn)換工具.
第一種:調(diào)起蘋(píng)果自帶的地圖進(jìn)行導(dǎo)航:

蘋(píng)果自帶的地圖不需要設(shè)置白名單,需要設(shè)置終點(diǎn)的經(jīng)緯度就行,需要導(dǎo)入#import <MapKit/MapKit.h>頭文件

//坐標(biāo)轉(zhuǎn)換
CLLocationCoordinate2D gcj02Coord = [JZLocationConverter bd09ToGcj02:loc];
    //用戶(hù)位置
    MKMapItem *currentLoc = [MKMapItem mapItemForCurrentLocation];
    //終點(diǎn)位置
    MKMapItem *toLocation = [[MKMapItem alloc]initWithPlacemark:[[MKPlacemark alloc]initWithCoordinate:gcj02Coord addressDictionary:nil] ];
    toLocation.name = title;
    
    NSArray *items = @[currentLoc,toLocation];
    NSDictionary *dic = @{
                          MKLaunchOptionsDirectionsModeKey : MKLaunchOptionsDirectionsModeDriving,
                          MKLaunchOptionsMapTypeKey : @(MKMapTypeStandard),
                          MKLaunchOptionsShowsTrafficKey : @(YES)
                          };
    [MKMapItem openMapsWithItems:items launchOptions:dic];
第二種:調(diào)起百度地圖進(jìn)行導(dǎo)航:

可以參考:百度地圖官方文檔 實(shí)現(xiàn)如下:

//百度地圖
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"baidumap://"]]) {
        NSString *urlString = [[NSString stringWithFormat:@"baidumap://map/direction?origin={{我的位置}}&destination=latlng:%f,%f|name:%@&mode=driving&coord_type=bd09ll",modelData.coordinate.latitude,modelData.coordinate.longitude, modelData.titleName] stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
       [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString: urlString]];
    }

參數(shù)設(shè)置可以參考文檔

第三種:調(diào)起高德地圖進(jìn)行導(dǎo)航:

可以參考:高德地圖官方文檔 實(shí)現(xiàn)如下:

CLLocationCoordinate2D gcj02Coord = [JZLocationConverter bd09ToGcj02:modelData.coordinate];

    float shopLat = gcj02Coord.latitude;
    float shoplng = gcj02Coord.longitude;
    
    //高德地圖
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"iosamap://"]]) {
        NSMutableDictionary *gaodeMapDic = [NSMutableDictionary dictionary];
        NSString *urlString = [[NSString stringWithFormat:@"iosamap://path?sourceApplication=%@&backScheme=%@&sname=我的位置&dev=1&t=0&dlat=%f&dlon=%f&dname=%@&dev=0",@"AppName",@"url schemes",shopLat,shoplng, modelData.titleName] stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
       [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString: urlString]];  
    }
第四種:調(diào)起騰訊地圖進(jìn)行導(dǎo)航:

可以參考:騰訊地圖官方文檔 實(shí)現(xiàn)如下:

//騰訊地圖
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"qqmap://"]]) {
        NSMutableDictionary *qqMapDic = [NSMutableDictionary dictionary];
        NSString *urlString = [[NSString stringWithFormat:@"qqmap://map/routeplan?from=我的位置&type=drive&tocoord=%f,%f&to=%@",shopLat,shoplng, modelData.titleName] stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
       [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString: urlString]]; 
    }
