在app中有許多場景須要用到導航,好比我給你發了一個地理位置,你能夠打開這個位置而後經過位置導航找到我.ios

導航能夠經過內嵌三方SDK實現也能夠經過跳轉三方app實現,後者相對前者來講相對簡單並且也能有效的減少app體積.下面就爲你們介紹下後者實現.git

// 代碼以下 這裏只添加了三種地圖 (蘋果官方地圖,高德,百度),若有其它須要能夠本身添加,若是沒有安裝高德或者百度地圖 sheet的titles裏面是不會顯示的

UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:@"選擇地圖" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:nil otherButtonTitles:nil, nil];
 
    if ( [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"http://maps.apple.com/"]])
    {
        [sheet addButtonWithTitle:@"蘋果地圖"];
    }
    
    if ( [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"baidumap://"]])
    {
        [sheet addButtonWithTitle:@"百度地圖"];
    }

    if ( [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"iosamap://"]])
    {
        [sheet addButtonWithTitle:@"高德地圖"];
    }

    [sheet showInView:self.view];

下面實現actionSheet的代理方法app

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
    NSString *title = [actionSheet buttonTitleAtIndex:buttonIndex];
    
    if ([title isEqualToString:@"蘋果地圖"]) {
            MKMapItem *currentLocation = [MKMapItem mapItemForCurrentLocation];
        MKMapItem *toLocation = [[MKMapItem alloc] initWithPlacemark:[[MKPlacemark alloc] initWithCoordinate:_currentLocationCoordinate addressDictionary:nil]];
        // 目的地名字
        toLocation.name = self.addressString;
        
            [MKMapItem openMapsWithItems:@[currentLocation, toLocation]
                           launchOptions:@{MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeDriving,MKLaunchOptionsShowsTrafficKey: [NSNumber numberWithBool:YES]}];

    } else if ([title isEqualToString:@"高德地圖"]) {
            NSString *urlString = [[NSString stringWithFormat:@"iosamap://navi?sourceApplication=%@&backScheme=%@&lat=%f&lon=%f&dev=0&style=2",self.appName,self.urlScheme,
                                    _toLocationCoordinate.latitude,
                                    _toLocationCoordinate.longitude]
                                   stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];

    } else if ([title isEqualToString:@"百度地圖"]) {
            NSString *urlString = [[NSString stringWithFormat:@"baidumap://map/direction?origin=%f,%f&destination=latlng:%f,%f|name:%@&mode=driving&src=dangdang://&coord_type=gcj02",
                                    _myLocation.latitude,_myLocation.longitude,
                                    _toLocationCoordinate.latitude,
                                    _toLocationCoordinate.longitude,
                                    self.addressString] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

            NSLog(@"%@",urlString);

            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];
    }
}

// 通用參數
self.appName = app名稱 self.urlScheme = appUrlScheme _toLocationCoordinate = 目的地經緯度url

// 只有調用百度地圖才須要當前的經緯度
_myLocation = 當前經緯度 spa

具體這些URL以及參數的設置均可以在官方文檔查看
須要注意的是 iOS9.0以上的系統須要在info.plist文件設置白名單才能調起三方地圖代理
