OpenURL in iOS10
提问by KSigWyatt
So apparently OpenURLhas been deprecated in iOS 10. Does anyone have any documentation on why or can explain what to do next? I looked on the Apple site already and found a few things pertaining to OpenURL and this is what they say to use now:
所以显然OpenURL在 iOS 10 中已被弃用。 有没有人有任何关于为什么或可以解释下一步做什么的文档？我已经查看了 Apple 网站，发现了一些与 OpenURL 相关的内容，这就是他们现在所说的：
UIApplication.shared().open(url: URL, options: [String: AnyObject], completionHandler: ((Bool) -> Void)?)
Does anyone have any evidence that this is the new way to use OpenURL in Swift 3.0? In addition what values are to be used in the options:and completionHandler:parameters respectively?
有没有人有任何证据表明这是在 Swift 3.0 中使用 OpenURL 的新方法？另外分别在options:和completionHandler:参数中使用什么值？

Swift 3+:
斯威夫特 3+：
func open(scheme: String) {
if let url = URL(string: scheme) {
if #available(iOS 10, *) {
UIApplication.shared.open(url, options: [:],
completionHandler: {
(success) in
print("Open \(scheme): \(success)")
})
} else {
let success = UIApplication.shared.openURL(url)
print("Open \(scheme): \(success)")
}
}
}

A quick fix:
快速修复：
// Objective-C
UIApplication *application = [UIApplication sharedApplication];
[application openURL:URL options:@{} completionHandler:nil];

An emptyoptions dictionary will result in the same behaviour as openUrl.
一个空的字典选项将导致相同的行为的OpenURL。
Otherwise:
除此以外：
+-------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------+
| UIApplicationOpenURLOptionsSourceApplicationKey | NSString containing the bundle ID of the originating application |
+-------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------+
| UIApplicationOpenURLOptionsAnnotationKey | property-list typed object corresponding to what the originating application passed in UIDocumentInteractionController's annotation property |
+-------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------+
| UIApplicationOpenURLOptionsOpenInPlaceKey | bool NSNumber, set to YES if the file needs to be copied before use |
+-------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------+
From UIApplication.h
来自 UIApplication.h
// Options are specified in the section below for openURL options. An empty options dictionary will result in the same
// behavior as the older openURL call, aside from the fact that this is asynchronous and calls the completion handler rather
// than returning a result.
// The completion handler is called on the main queue.
- (void)openURL:(NSURL*)url options:(NSDictionary<NSString *, id> *)options completionHandler:(void (^ __nullable)(BOOL success))completion NS_AVAILABLE_IOS(10_0) NS_EXTENSION_UNAVAILABLE_IOS("");
UIKIT_EXTERN UIApplicationOpenURLOptionsKey const UIApplicationOpenURLOptionsSourceApplicationKey NS_SWIFT_NAME(sourceApplication) NS_AVAILABLE_IOS(9_0); // value is an NSString containing the bundle ID of the originating application
UIKIT_EXTERN UIApplicationOpenURLOptionsKey const UIApplicationOpenURLOptionsAnnotationKey NS_SWIFT_NAME(annotation) NS_AVAILABLE_IOS(9_0); // value is a property-list typed object corresponding to what the originating application passed in UIDocumentInteractionController's annotation property
UIKIT_EXTERN UIApplicationOpenURLOptionsKey const UIApplicationOpenURLOptionsOpenInPlaceKey NS_SWIFT_NAME(openInPlace) NS_AVAILABLE_IOS(9_0); // value is a bool NSNumber, set to YES if the file needs to be copied before use

The new UIApplication method openURL:options:completionHandler:, which is executed asynchronously and calls the specified completion handler on the main queue (this method replaces openURL:).
新的 UIApplication 方法 openURL:options:completionHandler:，异步执行并调用主队列上指定的完成处理程序（此方法替换 openURL:）。

You need to do some checking first before loading the url. Please check the codes below.
在加载 url 之前，您需要先进行一些检查。请检查下面的代码。
if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"https://www.gmail.com"]]){
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"https://www.gmail.com"] options:@{} completionHandler:^(BOOL success) {
//completion codes here
}];
}
I hope this helps.
我希望这有帮助。

let actual:
让实际：
[String: AnyObject] = ["xxx key": "xxx value" as AnyObject, "yyy key": "yyy value" as AnyObject]
UIApplication.shared.open(URL(string: "http:google.com")!, options: actual, completionHandler: {(true) -> Swift.Void in
print("Refresh")
})
Where xxx and yyy are any string you want to print or leave them blank .
其中 xxx 和 yyy 是您想要打印或留空的任何字符串。

If your app still support iOS 9or lower, just keep using the old openURL. You should only move to the new one if your Deployment Target is iOS 10.
如果您的应用程序仍然支持iOS 9或更低，请继续使用旧的openURL. 如果您的部署目标是 ，您应该只移动到新的iOS 10。

you can use function to open settings:
您可以使用函数打开设置：
func showAlert(title:String, message:String){
let alert = UIAlertController(title: title,
message: message,
preferredStyle: UIAlertController.Style.alert)
let okAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alert.addAction(okAction)
let settingsAction = UIAlertAction(title: "Settings", style: .default, handler: { _ in
// Take the user to Settings app to possibly change permission.
guard let settingsUrl = URL(string: UIApplication.openSettingsURLString) else { return }
if UIApplication.shared.canOpenURL(settingsUrl) {
if #available(iOS 10.0, *) {
UIApplication.shared.open(settingsUrl, completionHandler: { (success) in
// Finished opening URL
})
} else {
// Fallback on earlier versions
UIApplication.shared.openURL(settingsUrl)
}
}
})
alert.addAction(settingsAction)
present(alert, animated: true, completion: nil)
}
Call this function like this given below
像下面这样调用这个函数
showAlert(title: "Unable to access the Photos", message: "To enable access, go to Settings > Privacy > Photos and turn on Photos access for this app.")
