ios 跳转第三方App实现导航

释放双眼,带上耳机,听听看~!

要跳转第三方App实现导航就首先需要了解两个问题 1.怎么判断手机上是否安装了第三方导航App 2.怎么实现跳转到第三方App

问题1 比如你如果要检测是否有安装百度地图APP,那么就是:

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

常用的4个地图的 URL Scheme: 1.苹果自带地图(不需要检测,所以不需要URL Scheme) 2.百度地图 :baidumap:// 3.高德地图 :iosamap:// 4.谷歌地图 :comgooglemaps://

问题2 在 iOS 9 之后我们做跳转是需要有个白名单的

具体实现代码

#import <MapKit/MapKit.h>

@implementation ThirdAppNavigationManager

+ (void)thirdAppNavigation:(NSString *)lat lng:(NSString *)lng
{
    NSMutableArray *maps = [NSMutableArray array];
    
    //苹果原生地图-苹果原生地图方法和其他不一样

    [maps addObject:iosMapDic];
    
    //百度地图
