Waze doesn't load navigation from Swift

问题:

I integrated Waze into my Swift app, but when I click on the button, Waze opens but nothing happens with the navigation. I juste see the app and that's all, instead of launching the navigation.

Here is the code:

@IBAction func openWazeAction(_ sender: Any) {
    // open waze
    if UIApplication.shared.canOpenURL(URL(string: "waze://")!) {
        let urlStr = String(format: "waze://ul?ll=%f,%f&navigate=yes", (selectedBorne?.location?.x)!, (selectedBorne?.location?.y)!)

        print(urlStr)

        UIApplication.shared.open(URL(string: urlStr)!)
    } else {
        UIApplication.shared.open(URL(string: "http://itunes.apple.com/us/app/id323229106")!)
    }
}

The print(urlStr) returns the right URL: waze://ul?ll=48.792914,2.366290&navigate=yes, but nothing happens in the Waze app.

(I put the LSApplicationQueriesSchemes in the Info.plist file.)

What is wrong here?

回答1:

I fixed the problem. The Waze documentation gives wrong information because their iOS example doesn't open the Waze app as it should be. It opens Safari on mobile and then we need to click on a link to open Waze.

The correct link is:

waze://?ll={latitude},{longitude}&navigate=yes

I needed to remove ul in the URL.

Swift

func navigateTo(latitude: Double, longitude: Double) {
    if UIApplication.shared.canOpenURL(URL(string: "waze://")!) {
        // Waze is installed. Launch Waze and start navigation
        let urlStr = String(format: "waze://?ll=%f,%f&navigate=yes", latitude, longitude)
        UIApplication.shared.open(URL(string: urlStr)!)
    } else {
        // Waze is not installed. Launch AppStore to install Waze app
        UIApplication.shared.open(URL(string: "http://itunes.apple.com/us/app/id323229106")!)
    }
}

Objective-C

(void) navigateToLatitude:(double)latitude longitude:(double)longitude
{
  if ([[UIApplication sharedApplication]
    canOpenURL:[NSURL URLWithString:@"waze://"]]) {
      // Waze is installed. Launch Waze and start navigation
      NSString *urlStr =
        [NSString stringWithFormat:@"waze://?ll=%f,%f&navigate=yes",
        latitude, longitude];
      [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlStr]];
  } else {
    // Waze is not installed. Launch AppStore to install Waze app
    [[UIApplication sharedApplication] openURL:[NSURL
      URLWithString:@"http://itunes.apple.com/us/app/id323229106"]];
  }
}
