Question

我已经审查了关于向谷歌地图应用发送用户的 Apple果文件(http://developer.apple.com/library/ios/#featuredarticles/iPhoneURLScheme_Reference/Articles/MapLinks.html),我有一个问题,即“我是否自动将用户目前地点的指示带到预定的排位/长地点?

The Apple Docs say to use "saddr=" and "daddr=" for the source and destination respectively, but it doesn t say how to acquire the user s current location. Is there some sort of keyword such as "saddr=Current" or "saddr=Here" that will get the user s location?

显然,这并不奏效:

[app openURL:[NSURL URLWithString:@"http://maps.google.com/maps?saddr=Here&daddr=Chicago"]];

如果我试图将用户送往芝加哥。任何想法?

Answer 1

我认为,saddr=Current%20Location&daddr=......是你想要的。

SOURCE: How to invoke iPhone Maps for Directions with Current Location as Start Address

你们需要利用核心位置来找到目前的位置,但随着时间的推移,你可以绘制地图,把你从那里前往街道地址。与此类似:

CLLocationCoordinate2D currentLocation = [self getCurrentLocation];
   NSString* address = @"123 Main St., New York, NY, 10001";
   NSString* url = [NSString stringWithFormat: @"http://maps.google.com/maps?saddr=%f,%f&daddr=%@",
                    currentLocation.latitude, currentLocation.longitude,
                    [address stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
   [[UIApplication sharedApplication] openURL: [NSURL URLWithString: url]];

Answer 3

我不认为你可以直接这样做。但是,通过使用<代码>saddr=lat,long(例如addr=53.453209,-0.32930)的方式,您可将坐标划入参数。因此,如果你向谷歌地图发送到你面前的用户目前的位置,你就获得了该功能的近似值。

Answer 4

你们只能使用目前加热器在ur中可悲的部分。这一工作在SiOS进行,但我找不到安乐团的工作。

Answer 5

谷歌地图只用daddr para amount set,使谷歌地图自动在From现场插入用户目前的位置。

Answer 6

您总是能够利用SiOS的逆向地名录来获取现有地点地址(即用户让你获得其位置),并在URL中加以使用,网址是:是指用于扭转地理编码的类别。

NSString* directionsURL = [NSString stringWithFormat:@"http://maps.apple.com/?saddr=%f,%f&daddr=%f,%f",self.mapView.userLocation.coordinate.latitude, self.mapView.userLocation.coordinate.longitude, mapPoint.coordinate.latitude, mapPoint.coordinate.longitude];
if ([[UIApplication sharedApplication] respondsToSelector:@selector(openURL:options:completionHandler:)]) {
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString: directionsURL] options:@{} completionHandler:^(BOOL success) {}];
} else {
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString: directionsURL]];
}
