c# - 没有设备注册 Parse Push 和 Xamarin IOS
<p><p>我正在尝试使用 Parse Push 和 Xamarin IOS 设置推送通知。我遵循了这些指南:</p>

<a href="https://groups.google.com/forum/#!topic/parse-developers/65WAfRIiEnA" rel="noreferrer noopener nofollow">https://groups.google.com/forum/#!topic/parse-developers/65WAfRIiEnA</a> </p>
<p>根据我对我的 AppDelegate 的修改的理解，</p>
<p>我在构造函数中添加了这个:</p>
<pre><code>ParseClient.Initialize("MY APP ID", "MY DOT NET KEY");
</code></pre>
<p>使用适当的键。</p>
<p>我将它添加到 FinishedLaunching 方法中</p>
<pre><code>if (Convert.ToInt16(UIDevice.CurrentDevice.SystemVersion.Split('.').ToString()) < 8) {
UIRemoteNotificationType notificationTypes = UIRemoteNotificationType.Alert | UIRemoteNotificationType.Badge | UIRemoteNotificationType.Sound;
UIApplication.SharedApplication.RegisterForRemoteNotificationTypes(notificationTypes);
} else {
UIUserNotificationType notificationTypes = UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound;
var settings = UIUserNotificationSettings.GetSettingsForTypes(notificationTypes, new NSSet(new string[] { }));
UIApplication.SharedApplication.RegisterUserNotificationSettings(settings);
UIApplication.SharedApplication.RegisterForRemoteNotifications();
}
// Handle Push Notifications
ParsePush.ParsePushNotificationReceived += (object sender, ParsePushNotificationEventArgs args) => {
Utils.Log("Push!");
};
</code></pre>
<p>然后我添加了适当的覆盖:</p>
<pre><code>public override void DidRegisterUserNotificationSettings(UIApplication application,
UIUserNotificationSettings notificationSettings) {
application.RegisterForRemoteNotifications();
}
public override void RegisteredForRemoteNotifications(UIApplication application,
NSData deviceToken) {
ParseInstallation installation = ParseInstallation.CurrentInstallation;
installation.SetDeviceTokenFromData(deviceToken);
installation.SaveAsync();
}
public override void FailedToRegisterForRemoteNotifications (UIApplication application , NSError error)
{
new UIAlertView("Error registering push notifications", error.LocalizedDescription, null, "OK", null).Show();
}
public override void ReceivedRemoteNotification(UIApplication application,
NSDictionary userInfo) {
// We need this to fire userInfo into ParsePushNotificationReceived.
ParsePush.HandlePush(userInfo);
}
</code></pre>
<p>但还是没有运气。</p>
<p>我在 RegisteredForRemoteNotifications 方法中添加了一个断点，它确实被调用了，所以我显然是在注册通知，但是当我尝试从 parse 发送推送通知时，它告诉我“没有注册设备”。</p>
<p>我尝试过的事情:</p>
<ul>
<li>检查配置文件是否已设置推送通知。</li>
<li>删除所有远程和本地配置文件，然后重新生成它们。</li>
<li>确保通过构建使用新的配置文件。</li>
<li>重新生成 .p12 文件并重新上传以进行解析。</li>
<li>在 Info.plist 和 prov 配置文件中检查我的包标识符是否一致。</li>
</ul>
<p>但我想这不是配置文件的问题，因为该应用正在注册通知，</p>
<p>Parse 为什么不同意？</p>
<p>我错过了什么？</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>我也遇到了同样的问题。我已经按照教程重新创建了配置文件、.p12 等，就像你一样。仍然没有运气。我按照这里的示例进行了手动操作 - <a href="https://www.parse.com/docs/rest/guide/#push-notifications-uploading-installation-data" rel="noreferrer noopener nofollow">https://www.parse.com/docs/rest/guide/#push-notifications-uploading-installation-data</a>并通过 curl 命令注册我的设备:</p>
<pre><code>curl -X POST \
-H "X-Parse-Application-Id: <Your Parse app ID> " \
-H "X-Parse-REST-API-Key: <Your parse REST API key>" \
-H "Content-Type: application/json" \
-d '{
"deviceType": "ios",
"deviceToken": "<Your device token>",
"channels": [
""
]
}' \
https://api.parse.com/1/installations
</code></pre>
<p>这样做后，我立即看到我的设备已注册。我尝试发送推送通知，但尚未收到。有些东西告诉我 Xamarin 安装或证书/配置文件存在问题。我还在努力解决这个问题，如果我解决了我会更新。</p>
<p>编辑 1:我发现如果您卸载正在使用的应用程序并重新安装，那么您的设备 token 会更改。无论如何，所以我再次尝试了一些不同的东西，我启动了我的应用程序并通过 xamarin 在 Debug模式下运行它。我捕获了新的设备 token 并再次发出了那个 curl 命令。 Parse 现在告诉我我注册了两个设备。我点击了我的应用程序上的主页按钮并告诉 parse 触发推送通知，我收到了它。所以现在我正在调查应用程序是否正确注册了 parse。它似乎试图进行通信，但某处可能出现错误，我不确定它可能是什么。</p>
<p>更新:所以我终于让我的设备注册了，但采用了完全不同的方式。这是我的 RegisteredForRemoteNotifications 现在的样子。 (注意:<em>我正在使用 Parse 1.5.5，因为在撰写本文时，新版本无法正常工作。目前最新版本是 1.6.2。</em>)</p>
<pre><code>public override void RegisteredForRemoteNotifications(UIApplication application, NSData deviceToken) {
ParseObject obj = ParseObject.Create ("_Installation");
string dt = deviceToken.ToString ().Replace ("<", "").Replace (">", "").Replace (" ", "");
obj["deviceToken"] = dt;
obj.SaveAsync ().ContinueWith (t => {
if (t.IsFaulted) {
using (IEnumerator<System.Exception> enumerator = t.Exception.InnerExceptions.GetEnumerator()) {
if (enumerator.MoveNext()) {
ParseException error = (ParseException) enumerator.Current;
Console.WriteLine ("ERROR!!!: " + error.Message);
}
}
} else {
Console.WriteLine("Saved/Retrieved Installation");
var data = NSUserDefaults.StandardUserDefaults;
data.SetString ("currentInstallation", obj.ObjectId);
Console.WriteLine("Installation ID = " + obj.ObjectId);
}
});
}
</code></pre>
<p>我还是想知道为什么我们不能这样做</p>
<pre><code>public override void RegisteredForRemoteNotifications(UIApplication application, NSData deviceToken) {
ParseInstallation installation = ParseInstallation.CurrentInstallation;
installation.SetDeviceTokenFromData(deviceToken);
installation.SaveAsync();
}
</code></pre>
<p>但现在我有一些可行的方法。</p></p>
