iOS9以前的可以通過
[[UIApplication sharedApplication]canOpenURL:[NSURL URLWithString:@"baidumap://map/"]]
[[UIApplication sharedApplication]canOpenURL:[NSURL URLWithString:@"iosamap://"]]
可以判讀是否安裝的百度地圖與高德地圖。而后通過
//打開百度地圖導航
- (void)openBaiDuMap{
NSString *urlString = [[NSString stringWithFormat:@"baidumap://map/direction?origin=latlng:%f,%f|name:我的位置&destination=latlng:%f,%f|name:終點&mode=driving",currentLatitude, currentLongitude,_shopLat,_shopLon] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding] ;
[[UIApplication sharedApplication]openURL:[NSURL URLWithString:urlString]];
}
//打開高德地圖導航
- (void)openGaoDeMap{
NSString *urlString = [[NSString stringWithFormat:@"iosamap://navi?sourceApplication=%@&backScheme=%@&poiname=%@&lat=%f&lon=%f&dev=1&style=2",@"app name", @"YGche", @"終點", _shopLat, _shopLon] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
[[UIApplication sharedApplication]openURL:[NSURL URLWithString:urlString]];
}
//打開蘋果自帶地圖導航
- (void)openAppleMap{
//起點
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 };
//打開蘋果自身地圖應用，并呈現特定的item
[MKMapItem openMapsWithItems:items launchOptions:options];
}
在更新iOS9后原來的方法不起做用了。解決辦法：
在info.plist添加白名單
<key>LSApplicationQueriesSchemes</key>
<array>
? ? ?<string>baidumap</string>
? ? ?<string>iosamap</string>
</array>
