最簡(jiǎn)單快捷的方法使用高德地圖uri格侯，高德地圖uri的具體使用可在高德地圖官方網(wǎng)站看啸罢，使用非常簡(jiǎn)單
簡(jiǎn)單貼下部分代碼
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];

這種實(shí)現(xiàn)方式柒室，點(diǎn)擊導(dǎo)航的時(shí)候可以設(shè)置直接跳轉(zhuǎn)到高德地圖履磨，但是如果用戶沒有安裝高德地圖的話蛉抓，就直接跳轉(zhuǎn)到App Store ，用戶體驗(yàn)不是很好
所以后來需求改成蹬耘，點(diǎn)擊了立即導(dǎo)航讓選擇使用本地已經(jīng)安裝的地圖

那么現(xiàn)在問題出現(xiàn)了芝雪，立即導(dǎo)航的按鈕是高德web頁面的方法，iOS 怎么監(jiān)聽事件呢综苔，于是就搜索了各種方法惩系，最后選擇通過UIWebView 的代理方法監(jiān)聽
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
webview 每次加載都會(huì)調(diào)用這個(gè)方法，可以通過request.url 來判斷用戶是否點(diǎn)擊了立即導(dǎo)航按鈕
代碼如下
- (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(@"點(diǎn)擊了導(dǎo)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;
}
立即導(dǎo)航的點(diǎn)擊事件截取到之后如筛，然后堡牡，在通過[UIApplication sharedApplication] canOpenURL: 方法來判斷本地安裝了哪些地圖
高德地圖：iosamap://
百度地圖：baidumap://
高德，百度 杨刨，蘋果地圖的跳轉(zhuǎn)方法：本文中跳轉(zhuǎn)到地圖顯示效果是這樣的晤柄，需要傳入終點(diǎn)的經(jīng)緯度
