在iPhone的谷歌地图上显示方向。

Posted 2021-02-25

Here is a peace of code from one of my project to show you how you to show directions on the Google Map application.

- (void)showDirections {
	if ([self.address length] == 0) return;
	//We create our link to the appDelegate
	ClubPlanetControllerAppDelegate * appDelegate = (ClubPlanetControllerAppDelegate *)[UIApplication sharedApplication].delegate;
 
 
	NSURL *myURL = [NSURL URLWithString:[NSString stringWithFormat:@"http://maps.google.com/maps?daddr==%@&saddr=%f,%f", [self.address stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding], [appDelegate.lat floatValue], [appDelegate.lon floatValue]]];
	[[UIApplication sharedApplication] openURL:myURL];
}
