切换无法从原生应用程序到网站 [英] Handoff not working from native app to website

问题描述

我的设备：

• iPad Mini（最新），iOS 8 dp5。


• Macbook Air，Yosemite dp5。

我在上述两个设备之间进行了Handoff工作。 Safari，邮件，消息，日历等都可以毫无问题地进行切换。

我甚至可以在我的Air on Air网站和iPad上的原生应用程序之间进行切换。 / p>

我还不能做的是从我在iPad上的原生应用程序转到我的Air上的Safari网站。

对于在我的原生应用中加载的第一个视图控制器，我有：

   - （void）viewDidLoad 
 
 {
 [super viewDidLoad]; 
 
 NSUserActivity * webHandoff = [[NSUserActivity alloc] initWithActivityType：@com.myApp.iphone.staging.webbrowsing]; 
 
 webHandoff.webpageURL = [NSURL URLWithString：@http://staging.myApp.com]; 
 
 [webHandoff becomeCurrent]; 
} 
  

在我的应用程序的Info.plist文件中，我有：

 < key> NSUserActivityTypes< / key> 
< array> 
< string> com.myApp.iphone.staging.webbrowsing< / string> 
< / array> 
  

我错过了什么或者我的配置错误了吗？

感谢您的帮助！

解决方案

我对我的代码做了两处重大修改：

1）配置/销毁并在viewDidAppear / disappear中设置NSUserActivity对象，而不是viewDidLoad：

   - （void）viewDidAppear：（BOOL）animated 
 {
 [super viewDidAppear：animated]; 
 
 NSUserActivity * webHandoff = [[NSUserActivity alloc] initWithActivityType：@com.myApp.iphone.staging.web-browsing]; 
 webHandoff.webpageURL = self.handoffWebpageURL; 
 [self setUserActivity：webHandoff]; 
} 
 
  - （void）viewDidDisappear：（BOOL）动画
 {
 [super viewDidDisappear：animated]; 
 
 [self.userActivity invalidate]; 
} 
  

2）由于UIViewController是UIResponder的子类，UIResponders具有userActivity属性，而不是调用 [webHandoff becomeCurrent] 我只是调用 [self setUserActivity：webHandoff];

不确定为什么将它从viewDidLoad中移出有任何影响，并且不确定为什么我需要将它设置为viewController的NSUserActivity实例，但上面的更改为我提供了一个稳定可靠的切换体验整个应用程序。

My devices:

• iPad Mini (latest), iOS 8 dp5.
• Macbook Air, Yosemite dp5.

I have Handoff working between the two above devices. Safari, Mail, Messages, Calendar, etc. all handoff with no problems.

I can even handoff between my website on the Air and my native app on the iPad.

What I can't do yet is go from my native app on the iPad to my website in Safari on my Air.

For the first view controller that loads in my native app, I have this:

- (void)viewDidLoad

{
    [super viewDidLoad];

    NSUserActivity *webHandoff = [[NSUserActivity alloc] initWithActivityType:@"com.myApp.iphone.staging.webbrowsing"];

    webHandoff.webpageURL = [NSURL URLWithString:@"http://staging.myApp.com"];

    [webHandoff becomeCurrent];
}

In my app's Info.plist file, I have this:

<key>NSUserActivityTypes</key>
<array>
      <string>com.myApp.iphone.staging.webbrowsing</string>
</array>

Am I missing something or do I have something configured incorrectly?

Thanks for any help!

解决方案

I made two significant changes to my code:

1) configure/destroy and set the NSUserActivity object in viewDidAppear/disappear as opposed to viewDidLoad:

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    NSUserActivity *webHandoff = [[NSUserActivity alloc] initWithActivityType:@"com.myApp.iphone.staging.web-browsing"];
    webHandoff.webpageURL = self.handoffWebpageURL;
    [self setUserActivity:webHandoff];
}

- (void)viewDidDisappear:(BOOL)animated
{
    [super viewDidDisappear:animated];

    [self.userActivity invalidate];
}

2) Since UIViewController is a subclass of UIResponder and UIResponders have a userActivity property, instead of calling [webHandoff becomeCurrent] I simply called [self setUserActivity:webHandoff];

Not sure why moving it out of viewDidLoad had any impact, and not sure why I need to set it to the viewController's instance of NSUserActivity, but the changes above give me a solid and reliable handoff experience throughout my entire app.
