最简单快捷的方法使用高德地图uri，高德地图uri的具体使用可在高德地图官方网站看，使用非常简单
简单贴下部分代码
NSString *urlStr = [NSString stringWithFormat:@"http://uri.amap.com/navigation?from=%f,%f,我的位置&to=%@,%@,%@&mode=car&policy=1&src=mypage&coordinate=gaode&callnative=0",self.currentLocation.coordinate.longitude,self.currentLocation.coordinate.latitude,model.lng,model.lat,model.swjg_mc];
self.webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, ScreenWidth, ScreenHeight-64)];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:[NSString encodeToPercentEscapeString: urlStr]]];
[self.webView loadRequest:request];
self.webView.delegate = self;
[self.view addSubview:self.webView];

这种实现方式，点击导航的时候可以设置直接跳转到高德地图，但是如果用户没有安装高德地图的话，就直接跳转到App Store ，用户体验不是很好
所以后来需求改成，点击了立即导航让选择使用本地已经安装的地图

那么现在问题出现了，立即导航的按钮是高德web页面的方法，iOS 怎么监听事件呢，于是就搜索了各种方法，最后选择通过UIWebView 的代理方法监听
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
webview 每次加载都会调用这个方法，可以通过request.url 来判断用户是否点击了立即导航按钮
代码如下
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
NSURL *url = [request URL];
BOOL returnValue = YES;
if ([url.absoluteString containsString:@"iosamap"] || [url.absoluteString containsString:@"amapuri://route/plan/"]) {
NSLog(@"点击了导航======================%@",url.absoluteString);
[self showSheetView];
//注意不要直接 return NO;
returnValue = NO;
}
if ([url.absoluteString containsString:@"wap.amap.com"]) {
returnValue = NO;
}
return returnValue;
}
立即导航的点击事件截取到之后，然后，在通过[UIApplication sharedApplication] canOpenURL: 方法来判断本地安装了哪些地图
高德地图：iosamap://
百度地图：baidumap://
高德，百度 ，苹果地图的跳转方法：本文中跳转到地图显示效果是这样的，需要传入终点的经纬度
