前言
- App内根據手機上裝載的地圖App将其顯示在彈出的選擇框,選擇對應地圖跳轉進入地圖導航。需要用到
方法判斷手機是否已安裝相應地圖App。- (BOOL)canOpenURL:(NSURL *)url NS_AVAILABLE_IOS(3_0);
- 要進行跳轉需要先在xcode的plist檔案内将目标App的url Scheme加入白名單(LSApplicationQueriesSchemes)。
常見第三方地圖App的url Scheme
- 百度地圖:baidumap
- 高德地圖:iosamap
- 谷歌地圖:comgooglemaps
- 騰訊地圖:qqmap
plist檔案新增
LSApplicationQueriesSchemes
關鍵字,類型為NSArray,并在其下添加子目錄,類型為NSString,内容為各地圖對應的url Scheme。
白名單LSApplicationQueriesSchemes:
