打开带有特定地址 iOS 7 的地图答案

【问题标题】：Open maps with specific address iOS 7打开带有特定地址 iOS 7 的地图

【问题描述】：

我正在尝试让我的应用程序打开苹果地图应用程序并提取地址。我试过这个：

- (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];
}

还有这个：

- (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];
}

但按钮的行为就像它没有钩住一样。但这确实有效：

- (IBAction)openInMaps:(id)sender {
    NSString *addressString = @"http://maps.apple.com/?q=Cupertino,CA";
    NSURL *url = [NSURL URLWithString:addressString];
    [[UIApplication sharedApplication] openURL:url];
}

因此，只要它们是空间，它就不起作用。我怎样才能打开这个地址？

试一试文档developer.apple.com/library/ios/featuredarticles/…
谢谢，我什至不知道那里有...我去看看
我去吧：NSString *addressString = [NSString stringWithFormat:@"maps.apple.com/?q=1+Infinite+Loop,+Cupertino,+CA"];
不要不必要地使用stringWithFormat:。直接分配字符串即可。

【解决方案1】：

您需要正确转义 URL 中的空格：

NSString *addressString = @"http://maps.apple.com/?q=1%20Infinite%20Loop,%20Cupertino,%20CA";

编辑 - 似乎使用 + 而不是 %20 的空格可以解决问题。

所以要让它正常工作，你必须使用这个：

NSString *addressString = @"http://maps.apple.com/?q=1+Infinite+Loop,+Cupertino,+CA";

仍然像按钮什么都不做一样。但是，我收到错误消息：无效的转换说明符“I”。我知道这意味着什么，但你如何解决？

【解决方案2】：

Swift 2 版本的格式很好，可以安全地处理选项，并且不会让您的应用崩溃：

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)
}

这就是我在 Objective C 中的做法......我总是先尝试 Waze Map，因为老实说，它很棒，我在最后添加了 PLIST 文件权限：

- (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 版本：

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)
