公司产品需要用到地图功能，不过由于只是展示地图上的位置信息，所以没有集成地图，改为跳转到高德或者百度地图，如果都没有就跳转到safari上的网页地图。

• 第一步. 首先配置infoPlist

info_plist.png

• 第二步. 找高德或者百度的API信息-高德文档 ，百度文档

• 第三步：代码部分

//ios10以后OpenURL要用新方法
if ([[UIDevice currentDevice].systemVersion integerValue] >= 10)
    {
        NSDictionary *options = @{UIApplicationOpenURLOptionsSourceApplicationKey:@YES};
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[self getAmapUrl:request]] options:options completionHandler:^(BOOL success) {
//这里的success不管有没有安装高德地图值都是YES, 所以是否打开成功不能用这个参数判断
//所以在appdelegate里面添加了参数openingExternalProgram判断是否有打开高德或者百度

            if (((AppDelegate *)[UIApplication sharedApplication].delegate).openingExternalProgram) {
