公司產(chǎn)品需要用到地圖功能舟铜，不過(guò)由于只是展示地圖上的位置信息，所以沒(méi)有集成地圖，改為跳轉(zhuǎn)到高德或者百度地圖屯曹，如果都沒(méi)有就跳轉(zhuǎn)到safari上的網(wǎng)頁(yè)地圖。

• 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-高德文檔 惊畏，百度文檔

• 第三步：代碼部分

//ios10以后OpenURL要用新方法

        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[self getAmapUrl:request]] options:options completionHandler:^(BOOL success) {
//這里的success不管有沒(méi)有安裝高德地圖值都是YES, 所以是否打開(kāi)成功不能用這個(gè)參數(shù)判斷
//所以在appdelegate里面添加了參數(shù)openingExternalProgram判斷是否有打開(kāi)高德或者百度
