demo中有两处这样的判断
if ([[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]])
// -- 使用 canOpenURL:[NSURL URLWithString:@"baidumap://"] 判断不明白为什么为否。
原因是如下
if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"baidumap://"]])
// -- 使用 canOpenURL 判断需要在info.plist 的 LSApplicationQueriesSchemes 添加 baidumap 。
