OpenURL在iOS10
所以显然OpenURL已经在iOS 10中折旧了。有没有人有任何文档说明为什么或可以解释下一步该做什么？ 我已经查看了苹果网站，发现了一些与OpenURL有关的事情，这就是他们现在所说的：
UIApplication.shared().open(url: URL, options: [String: AnyObject], completionHandler: ((Bool) -> Void)?)
有没有人有任何证据certificate这是在Swift 3.0中使用OpenURL的新方法？ 另外在options:和completionHandler:参数中分别使用了什么值？
如果您使用iOS10兼容代码更新您的应用，还可以使用条件检查：
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)") } } }
用法：
open(scheme: "tweetbot://timeline")

快速修复：
// Objective-C UIApplication *application = [UIApplication sharedApplication]; [application openURL:URL options:@{} completionHandler:nil]; // Swift UIApplication.shared.open(url, options: [:], completionHandler: nil)

空的选项字典将导致与openUrl相同的行为。
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 | +-------------------------------------------------+----------------------------------------------------------------------------------------------------------------------------------------------+
从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
新的UIApplication方法openURL：options：completionHandler：，它是asynchronous执行的，并在主队列上调用指定的完成处理程序（此方法replaceopenURL :)。
这是在其他框架更改 > UIKit在： https : //developer.apple.com/library/prerelease/content/releasenotes/General/WhatsNewIniOS/Articles/iOS10.html
如果您的应用程序仍然支持iOS 9或更低版本，请继续使用旧的openURL 。 如果您的部署目标是iOS 10则只应移至新的目标。
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 }]; }
我希望这有帮助。
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") })
xxx和yyy是你想要打印的string，或者留空。
