專案裡面要求點擊發送的位置,  需要導航, 導航兩種實現方式 (整合第三方SDK、URL跳轉第三方應用)  專案要求實現直接跳轉 所以接下來做的是實現URL跳轉第三方地圖來導航了
專案實現如下的效果:

思路：傳入的目的地經緯度,再呼叫第三方的導航

第三方導航是指以URL跳轉的方式(在iOS中就是以URL Scheme的方式)，直接跳到對應的地圖APP中，直接利用對方的功能來導航。這樣的優點，一是接入方便，二是不增加自己APP的開銷。缺點就是如果使用者沒有裝這個地圖，應用就沒辦法使用這個地圖的服務。但是蘋果有個自帶的高德地圖，像流氓軟體一樣，刪也刪不掉，所以說這個跳轉是能實現的。

配置好白名單之後就要敲程式碼了  如果沒有安裝某個地圖App  那麼對應的選項就不應該出現
想要檢測手機是否安裝了某個地圖APP，只要呼叫下面這個方法就可以了：

[[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"XXX://"]];

下面開始擼程式碼:

第一：蘋果自帶地圖

蘋果提供了一種方式：MKMapItem（要使用記得匯入#import <MapKit/MapKit.h> 標頭檔案）

程式設計程式碼：

//蘋果地圖
- (void)navAppleMap
{
    CLLocationCoordinate2D gps = _currentLocationCoordinate;
    
    MKMapItem *currentLoc = [MKMapItem mapItemForCurrentLocation];
    MKMapItem *toLocation = [[MKMapItem alloc] initWithPlacemark:[[MKPlacemark alloc] initWithCoordinate:gps addressDictionary:nil]];
    NSArray *items = @[currentLoc,toLocation];
    NSDictionary *dic = @{
                          MKLaunchOptionsDirectionsModeKey : MKLaunchOptionsDirectionsModeWalking,
                          MKLaunchOptionsMapTypeKey : @(MKMapTypeStandard),
                          MKLaunchOptionsShowsTrafficKey : @(YES)
                          }; 
    
    [MKMapItem openMapsWithItems:items launchOptions:dic];
}
 

Demo如下:

#pragma mark ----導航方法-----------

- (NSArray *)getInstalledMapAppWithEndLocation:(CLLocationCoordinate2D)endLocation
{
    NSDictionary *infoDictionary = [[NSBundle mainBundle] infoDictionary];
    NSString *appName = [infoDictionary objectForKey:(NSString *)kCFBundleExecutableKey]; //獲取專案名稱
    NSMutableArray *maps = [NSMutableArray array];
    
    //蘋果地圖
    NSMutableDictionary *iosMapDic = [NSMutableDictionary dictionary];
    iosMapDic[@"title"] = @"蘋果地圖";
    [maps addObject:iosMapDic];
    
    //百度地圖
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"baidumap://"]]) {
        NSMutableDictionary *baiduMapDic = [NSMutableDictionary dictionary];
        baiduMapDic[@"title"] = @"百度地圖";
        NSString *urlString = [[NSString stringWithFormat:@"baidumap://map/direction?origin={{我的位置}}&destination=latlng:%f,%f|name=目的地&mode=walking&coord_type=gcj02",endLocation.latitude,endLocation.longitude] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
        baiduMapDic[@"url"] = urlString;
        [maps addObject:baiduMapDic];
    }
       //高德地圖
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"iosamap://"]]) {
        NSMutableDictionary *gaodeMapDic = [NSMutableDictionary dictionary];
        gaodeMapDic[@"title"] = @"高德地圖";
        NSString *urlString = [[NSString stringWithFormat:@"iosamap://navi?sourceApplication=%@&backScheme=%@&lat=%f&lon=%f&dev=0&style=2",appName,APP_SCHEMES,endLocation.latitude,endLocation.longitude] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
        gaodeMapDic[@"url"] = urlString;
        [maps addObject:gaodeMapDic];
    }
    
    //谷歌地圖
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"comgooglemaps://"]]) {
        NSMutableDictionary *googleMapDic = [NSMutableDictionary dictionary];
        googleMapDic[@"title"] = @"谷歌地圖";
        NSString *urlString = [[NSString stringWithFormat:@"comgooglemaps://?x-source=%@&x-success=%@&saddr=&daddr=%f,%f&directionsmode=walking",appName,@"nav123456",endLocation.latitude, endLocation.longitude] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
        googleMapDic[@"url"] = urlString;
        [maps addObject:googleMapDic];
    }
    
    //騰訊地圖
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"qqmap://"]]) {
        NSMutableDictionary *qqMapDic = [NSMutableDictionary dictionary];
        qqMapDic[@"title"] = @"騰訊地圖";
        NSString *urlString = [[NSString stringWithFormat:@"qqmap://map/routeplan?from=我的位置&type=walk&tocoord=%f,%f&to=終點&coord_type=1&policy=0",endLocation.latitude, endLocation.longitude] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
        qqMapDic[@"url"] = urlString;
        [maps addObject:qqMapDic];
    }
    
    return maps;
}

接著在點選導航呼叫的方法裡面,彈出提示框,設定代理方法:

- (void)navgationSender:(id)sender
{
    self.maps = [self getInstalledMapAppWithEndLocation:_currentLocationCoordinate];
    UIActionSheet *action = [[UIActionSheet alloc] init];
    for (NSDictionary *dic in self.maps) {
        [action addButtonWithTitle:[NSString stringWithFormat:@"%@", dic[@"title"]]];
    }
    [action addButtonWithTitle:@"取消"];
    action.cancelButtonIndex = self.maps.count;
    action.delegate = self;
    [action showInView:self.view];
    
}
#pragma mark UIActionSheetDelegate
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
    if (buttonIndex != -1 && buttonIndex < self.maps.count) {
        if (buttonIndex == 0) {
            [self navAppleMap];
            return;
        }
        NSDictionary *dic = self.maps[buttonIndex];
        NSString *urlString = dic[@"url"];
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];
    }
}

說一下注意事項:

1.引入標頭檔案

#import <CoreLocation/CoreLocation.h>

#import <MapKit/MapKit.h>

2.傳參

一：百度地圖

        NSString *urlString = [[NSString stringWithFormat:@"baidumap://map/direction?origin={{我的位置}}&destination=latlng:%f,%f|name=目的地&mode=walking&coord_type=gcj02",endLocation.latitude,endLocation.longitude] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

二：高德地圖

        NSString *urlString = [[NSString stringWithFormat:@"iosamap://navi?sourceApplication=%@&backScheme=%@&lat=%f&lon=%f&dev=0&style=2",appName,APP_SCHEMES,endLocation.latitude,endLocation.longitude] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

要注意幾點：

1. sourceApplication=%@&backScheme=%@
   sourceApplication代表你自己APP的名稱，會在之後跳回的時候顯示出來，所以必須填寫。backScheme是你APP的URL Scheme，不填是跳不回來的
2. dev=0
   這裡填0就行了，跟上面的gcj02一個意思 ，1代表wgs84， 也用不上。
