Question

我无法获得＆＃34; prefs＆＃34;在iOS 10中工作的URL方案。
它设置正确，因为相同的应用程序在iOS 9上正常工作。

这是一个错误还是重命名/删除了？

代码：

NSURL *url = [NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"];
if (![[UIApplication sharedApplication]canOpenURL:url]) {
    [[UIApplication sharedApplication]openURL:url]; 
}

Answer 1

iOS 10中的新方法：

//Objective-C
- (void)openURL:(NSURL*)url options:(NSDictionary<NSString *, id> *)options
  completionHandler:(void (^ __nullable)(BOOL success))completion


// Swift
open func open(_ url: URL, options: [String : Any] = [:],
  completionHandler completion: (@escaping (Bool) -> Swift.Void)? = nil)

使用iOS 10打开网址

// Objective-C
UIApplication *application = [UIApplication sharedApplication];
[application openURL:URL options:@{} completionHandler:nil];

// Swift
UIApplication.shared.open(url, options: [:], completionHandler: nil)

要用prefs替换App-Prefs，这是我的Swift帮助方法，以支持iOS 10及更低版本，在iOS 9及更高版本上测试10

class Helper {

    static func openLocationSettings() {
        if #available(iOS 10.0, *) {
            openSettings(url: "App-Prefs:root=Privacy&path=LOCATION")
        } else {
            openSettings(url: "prefs:root=LOCATION_SERVICES")
        }
    }

    static func openSettings(url: String) {
        guard let settingsUrl = URL(string: url), UIApplication.shared.canOpenURL(settingsUrl) else { return }

        if #available(iOS 10.0, *) {
            UIApplication.shared.open(settingsUrl)
        } else {
            UIApplication.shared.openURL(settingsUrl)
        }
    }

}

示例1 打开位置设置：

Helper.openLocationSettings()

示例2 打开应用程序设置：

Helper.openSettings(url: UIApplicationOpenSettingsURLString)

Answer 3

我建议首先验证方法可用性，然后使用适当的方法。

   if ([application respondsToSelector:@selector(openURL:options:completionHandler:)]) 
   {
      [application openURL:URL options:@{}
         completionHandler:^(BOOL success) {

            NSLog(@"Open URL Scheme %@: %d",scheme,success);
      }];
   } 
   else 
   {
      BOOL success = [application openURL:URL];
      NSLog(@"Open URL Scheme %@: %d",scheme,success);
   }

希望这有帮助。

Answer 4

将您的方案添加到您的plist作为您的一个URLSchemes

Answer 5

b = [a[i:i+2] for i in range(0, len(a), 2)] # ['10', 'F8', '00', ... c = [int(i, 16) for i in b] # [16, 248, 0, ... d = 256 - sum(c) % 256 # 0x30 e = hex(d)[2:] # '30'适用于iOS 10以下...因此选中了prefs:root=LOCATION_SERVICES和UIApplicationOpenSettingsURLString。两者都在为我工作....得到了@Rajan Balan的暗示。

App-Prefs:root=Privacy&path=LOCATION

哪里

if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]]) {
     if(SYSTEM_VERSION_GREATER_THAN(@"10")) {
          [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"App-Prefs:root=Privacy&path=LOCATION"]];

          // Below code is also working in iOS 10 to open location services
          // [[UIApplication sharedApplication] openURL:[NSURL URLWithString: UIApplicationOpenSettingsURLString]];

     } else {
          [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"]];
     }
}

“prefs”URL方案在iOS 10中不起作用
