iOS調用第三方地圖App進行導航方法

前言

• App內根據手機上裝載的地圖App將其顯示在彈出的選擇框，選擇對應地圖跳轉進入地圖導航。須要用到- (BOOL)canOpenURL:(NSURL *)url NS_AVAILABLE_IOS(3_0);方法判斷手機是否已安裝相應地圖App。
• 要進行跳轉須要先在xcode的plist文件內將目標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文件新增LSApplicationQueriesSchemes關鍵字，類型爲NSArray，並在其下添加子目錄，類型爲NSString，內容爲各地圖對應的url Scheme。

白名單LSApplicationQueriesSchemes:

//導航只須要目的地經緯度，endLocation爲緯度、經度的數組
-(void)doNavigationWithEndLocation:(NSArray *)endLocation
