Open maps with specific address iOS 7 - ios

Question

I am trying to make my application open the apple maps application and have the address be pulled up. I tried this :
- (IBAction)openInMaps:(id)sender {
NSString *addressString = #"http://maps.apple.com/?q=1 Infinite Loop, Cupertino, CA";
NSURL *url = [NSURL URLWithString:addressString];
[[UIApplication sharedApplication] openURL:url];
}
and this :
- (IBAction)openInMaps:(id)sender {
NSString *addressString = #"http://maps.apple.com/?q=1_Infinite_Loop,_Cupertino,_CA";
NSURL *url = [NSURL URLWithString:addressString];
[[UIApplication sharedApplication] openURL:url];
}
But the button just acts like its hooked to nothing. But this does work :
- (IBAction)openInMaps:(id)sender {
NSString *addressString = #"http://maps.apple.com/?q=Cupertino,CA";
NSURL *url = [NSURL URLWithString:addressString];
[[UIApplication sharedApplication] openURL:url];
}
So, whenever their is a space it doesn't work. How can I open this address?

Answer 1

You need to properly escape the spaces in the URL:
NSString *addressString = #"http://maps.apple.com/?q=1%20Infinite%20Loop,%20Cupertino,%20CA";
Edit - it seems using + instead of %20 for the spaces solves the problem.
So to get it to work properly you must use this :
NSString *addressString = #"http://maps.apple.com/?q=1+Infinite+Loop,+Cupertino,+CA";

Swift 2 version that is formatted nicely, safely handles optionals, and won't crash your app:
let baseUrl: String = "http://maps.apple.com/?q="
let encodedName = "address".stringByAddingPercentEncodingWithAllowedCharacters(.URLQueryAllowedCharacterSet()) ?? ""
let finalUrl = baseUrl + encodedName
if let url = NSURL(string: finalUrl) {
UIApplication.sharedApplication().openURL(url)
}

This is how I do it in Objective C...I always try the Waze Map first, because to be honest, it's awesome sauce, I added the PLIST file permissions at the end:
- (IBAction)getDirectionsAction:(id)sender {
NSURL *googleURL = [[NSURL alloc]
initWithString:[NSString stringWithFormat:#"comgooglemaps://?daddr=%#", #"44.294349,-70.326973"]];
NSURL *googleWebURL =
[[NSURL alloc] initWithString:[NSString stringWithFormat:#"http://www.maps.google.com/maps?daddr=%#",
#"44.294349,-70.326973"]];
NSURL *appleURL = [NSURL URLWithString:#"http://maps.apple.com/?daddr=311+East+Buckfield+Road+Buckfield+Maine"];
NSURL *wazeURL = [NSURL URLWithString:#"waze://?ll=44.294349,-70.326973&navigate=yes"];
// Lets try the Waze app first, cuz we like that one the most
if ([[UIApplication sharedApplication] canOpenURL:wazeURL]) {
[[UIApplication sharedApplication] openURL:wazeURL
options:#{}
completionHandler:^(BOOL success){
}];
return;
}
// Lets try the Apple Maps app second (great success rate)
if ([[UIApplication sharedApplication] canOpenURL:appleURL]) {
[[UIApplication sharedApplication] openURL:appleURL
options:#{}
completionHandler:^(BOOL success){
}];
return;
}
// If those 2 are unsuccessful, let's try the Google Maps app
if ([[UIApplication sharedApplication] canOpenURL:googleURL]) {
[[UIApplication sharedApplication] openURL:googleURL
options:#{}
completionHandler:^(BOOL success){
}];
return;
}
// Uh, oh...Well, then lets launch it from the web then.
else {
[[UIApplication sharedApplication] openURL:googleWebURL
options:#{}
completionHandler:^(BOOL success){
}];
}
}

Swift 3 version:
let baseUrl: String = "http://maps.apple.com/?q="
let encodedName = "yourAddress".addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)!
let finalUrl = baseUrl + encodedName
if let url = URL(string: finalUrl)
{
UIApplication.shared.open(url, options: [:], completionHandler: nil)
}

Swift 2
let baseUrl : String = "http://maps.google.com/?q="
let name : String = tableCellData[indexPath.row]
let encodedName = "address of yours"
name.stringByAddingPercentEncodingWithAllowedCharacters(.URLQueryAllowedCharacterSet())
let finalUrl = baseUrl + encodedName!
let url = NSURL(string: finalUrl)!
UIApplication.sharedApplication().openURL(url)
