App中如何打开百度或者高德地图
百度地图URI API地址
高德地图URI API地址
腾讯地图URI API地址
[[UIApplication sharedApplication]canOpenURL:[NSURL URLWithString:@"baidumap://map/"]]
[[UIApplication sharedApplication]canOpenURL:[NSURL URLWithString:@"iosamap://"]]
可以判读是否安装的百度地图与高德地图。而后通过
//打开百度地图导航
- (void)openBaiDuMap{
NSString *urlString =@"";
///打开百度地图app
urlString = [[NSString stringWithFormat:@"baidumap://map/direction?origin=latlng:%f,%f|name:%@&destination=latlng:%f,%f|name:%@&mode=driving®ion=%@&output=html",34.264642646862,108.95108518068,@"我的位置",39.98871,116.43234,@"天安门",@"吉林"] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding] ;
/////打开webapp（网页版）
//urlString = [[NSString stringWithFormat:@"https://api.map.baidu.com/direction?origin=latlng:%f,%f|name:%@&destination=latlng:%f,%f|name:%@&mode=driving®ion=%@&output=html",34.264642646862,108.95108518068,@"我的位置",39.98871,116.43234,@"天安门",@"吉林"] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding] ;
[[UIApplication sharedApplication]openURL:[NSURL URLWithString:urlString]];
}
//打开高德地图导航
- (void)openGaoDeMap{
NSString *urlString = [[NSString stringWithFormat:@"iosamap://navi?sourceApplication=%@&backScheme=%@&poiname=%@&lat=%f&lon=%f&dev=1&style=2",@"app name", @"YGche", @"终点", _shopLat, _shopLon] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
//urlString = [[NSString stringWithFormat:@"iosamap://path?sourceApplication=%@&sid=BGVIS1&slat=%f&slon=%f&sname=我的位置&did=BGVIS2&dlat=%f&dlon=%f&dname=%@&dev=0&m=0&t=0",@"点点吉林",39.92848272,116.39560823,39.98848272,116.47560823,@"终点"] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
// urlString = [[NSString stringWithFormat:@"http://m.amap.com/?from=%f,%f(我的位置)&to=%f,%f(终点)&type=0&opt=1",39.997361,116.478346,39.966577,116.3246] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
[[UIApplication sharedApplication]openURL:[NSURL URLWithString:urlString]];
}
//打开腾讯地图导航（暂不支持打开打开）
- (void)openBaiDuMap{
NSString *urlString =@"";
/////打开webapp（网页版）
NSString *urlString=@"";
urlString = [[NSString stringWithFormat:@"https://apis.map.qq.com/uri/v1/routeplan?type=drive&from=我的位置&fromcoord=39.980683,116.302&to=%@&tocoord=%f,%f&policy=1&referer=点点吉林",@"终点",latitude,longitude] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
[[UIApplication sharedApplication]openURL:[NSURL URLWithString:urlString]];
}
//打开苹果自带地图导航
- (void)openAppleMap{
//起点
CLLocationCoordinate2D coords1 = CLLocationCoordinate2DMake(currentLatitude,currentLongitude);
MKMapItem *currentLocation = [[MKMapItem alloc] initWithPlacemark:[[MKPlacemark alloc] initWithCoordinate:coords1 addressDictionary:nil]];
//目的地的位置
CLLocationCoordinate2D coords2 = CLLocationCoordinate2DMake(_shopLat,_shopLon);
MKMapItem *toLocation = [[MKMapItem alloc] initWithPlacemark:[[MKPlacemark alloc] initWithCoordinate:coords2 addressDictionary:nil]];
toLocation.name =address;
NSArray *items = [NSArray arrayWithObjects:currentLocation, toLocation, nil];
NSDictionary *options = @{ MKLaunchOptionsDirectionsModeKey:MKLaunchOptionsDirectionsModeDriving, MKLaunchOptionsMapTypeKey: [NSNumber numberWithInteger:MKMapTypeStandard], MKLaunchOptionsShowsTrafficKey:@YES };
//打开苹果自身地图应用，并呈现特定的item
[MKMapItem openMapsWithItems:items launchOptions:options];
}
在更新iOS9后原来的方法不起做用了。解决办法：
在info.plist添加白名单
LSApplicationQueriesSchemes
baidumap
iosamap
百度坐标、火星坐标、地球坐标间的转换
其中高德地图和腾讯地图用的是火星坐标
