最近在做導(dǎo)航混驰，所以把自己找到的資料總結(jié)一下攀隔！
無(wú)論是百度地圖、高德地圖栖榨、谷歌地圖還是騰訊地圖它們都有自己的SDK，我們只需要在自己的工程中導(dǎo)入SDK并查看相應(yīng)的官方文檔明刷，基本上就可以實(shí)現(xiàn)導(dǎo)航婴栽。但是這樣每個(gè)地圖的SDK都導(dǎo)入不但麻煩而且占用APP的內(nèi)存。最關(guān)鍵的是我們上傳到AppStore的包文件是有限制的辈末。所以我的原則是能不導(dǎo)入的SDK 就不導(dǎo)入愚争。

還有一種方式就是是以URI跳轉(zhuǎn)的方式(在iOS中就是以URL Scheme的方式)，直接跳到對(duì)應(yīng)的地圖APP中挤聘，直接利用對(duì)方的功能來(lái)導(dǎo)航轰枝。缺點(diǎn)是用戶(hù)沒(méi)有安裝對(duì)應(yīng)的APP就不能使用其進(jìn)行導(dǎo)航。 點(diǎn)擊導(dǎo)航按鈕會(huì)出現(xiàn)如下的彈窗组去， 當(dāng)然手機(jī)上未安裝的地圖 其名稱(chēng)就不會(huì)出現(xiàn)在彈窗上鞍陨。

在 iOS9之后 若想用URI方式跳轉(zhuǎn)到百度地圖、高德地圖从隆、騰訊地圖诚撵、谷歌地圖，需要你在info.plist加入這些東西键闺。（ps:LSApplicationQueriesSchemes寿烟，短的自己手打吧，另外注意類(lèi)型Ｐ猎铩）

以下出行的默認(rèn)方式都是駕車(chē)
一筛武、百度地圖
- 說(shuō)到百度地圖，就不得不說(shuō)它很坑爹挎塌。因?yàn)榘俣鹊貓D獲取的經(jīng)緯度徘六，是在GCJ-02(火星坐標(biāo))進(jìn)行偏移得到的經(jīng)緯度，而高德勃蜘、谷歌硕噩、騰訊都是使用GCJ-02坐標(biāo)體系得到的經(jīng)緯度。這樣使用百度地圖獲取到的經(jīng)緯度在高德缭贡、谷歌炉擅、騰訊上導(dǎo)航都會(huì)出現(xiàn)很大的偏差辉懒。所以自己做的APP中需要地圖功能最好不要導(dǎo)入百度地圖的SDK（使用上面三個(gè)中任何一個(gè)地圖獲取到的經(jīng)緯度都可以很容易的轉(zhuǎn)換成百度地圖需要的經(jīng)緯度），如果你是像我這樣中途接手的項(xiàng)目谍失，百度地圖的相應(yīng)功能已經(jīng)做好了眶俩，那你可以用下面的方式換算一下經(jīng)緯度（最下方）。
- 代碼如下 ：需傳入起點(diǎn)和終點(diǎn)的經(jīng)緯度
if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"baidumap://map/"]]) {
UIAlertAction *baiduMapAction = [UIAlertAction actionWithTitle:@"百度地圖" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
NSString *baiduParameterFormat = @"baidumap://map/direction?origin=latlng:%f,%f|name:我的位置&destination=latlng:%f,%f|name:終點(diǎn)&mode=driving";
NSString *urlString = [[NSString stringWithFormat:
baiduParameterFormat,
userLocation.location.coordinate.latitude,
userLocation.location.coordinate.longitude,
self.destinationCoordinate.latitude,
self.destinationCoordinate.longitude]
stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];
}];
[actionSheet addAction:baiduMapAction];
}

二颠印、高德地圖
- 只需傳入終點(diǎn)經(jīng)緯度 高德地圖能夠跳轉(zhuǎn)回你的APP，前提是backScheme=%@（你的APP的URL）要填寫(xiě)抹竹。代碼如下
if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"iosamap://map/"]]) {
UIAlertAction *gaodeMapAction = [UIAlertAction actionWithTitle:@"高德地圖" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
NSString *gaodeParameterFormat = @"iosamap://navi?sourceApplication=%@&backScheme=%@&poiname=%@&lat=%f&lon=%f&dev=1&style=2";
NSString *urlString = [[NSString stringWithFormat:
gaodeParameterFormat,
@"yourAppName",
@"yourAppUrlSchema",
@"終點(diǎn)",
self.destinationCoordinate.latitude,
self.destinationCoordinate.longitude]
stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];
}];
[actionSheet addAction:gaodeMapAction];
}

三线罕、蘋(píng)果地圖
- 需傳入起點(diǎn)和終點(diǎn)的經(jīng)緯度，并導(dǎo)入頭文件#import MapKit/MKMapItem.h>
[actionSheet addAction:[UIAlertAction actionWithTitle:@"蘋(píng)果地圖" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
//起點(diǎn)
MKMapItem *currentLocation = [MKMapItem mapItemForCurrentLocation];
CLLocationCoordinate2D desCorrdinate = CLLocationCoordinate2DMake(self.destinationCoordinate.latitude, self.destinationCoordinate.longitude);
//終點(diǎn)
MKMapItem *toLocation = [[MKMapItem alloc] initWithPlacemark:[[MKPlacemark alloc] initWithCoordinate:desCorrdinate addressDictionary:nil]];
//默認(rèn)駕車(chē)
[MKMapItem openMapsWithItems:@[currentLocation, toLocation]

MKLaunchOptionsMapTypeKey:[NSNumber numberWithInteger:MKMapTypeStandard],
MKLaunchOptionsShowsTrafficKey:[NSNumber numberWithBool:YES]}];
}]];

四窃判、谷歌地圖
- 只需傳入終點(diǎn)的經(jīng)緯度
if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"comgooglemaps://map/"]]) {
[actionSheet addAction:[UIAlertAction actionWithTitle:@"蘋(píng)果地圖"style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
NSString *urlString = [[NSString stringWithFormat:@"comgooglemaps://?x-source=%@&x-success=%@&saddr=&daddr=%f,%f&directionsmode=driving",

五钞楼、騰訊地圖
if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"qqmap://map/"]]) {
[actionSheet addAction:[UIAlertAction actionWithTitle:@"騰訊地圖" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
NSString *QQParameterFormat = @"qqmap://map/routeplan?type=drive&fromcoord=%f, %f&tocoord=%f,%f&coord_type=1&policy=0&refer=%@";
