我第一次使用Parse和Cloud Code来更新使用Parse和Objective-C for iOS 8构建的照片共享应用程序。我已按照Parse的说明设置推送通知并且已成功启用在照片被评论时收到通知，但它只提供“某人已对您的照片发表评论”的“其他”声明（而不是提供用户的姓名）。除此之外，“喜欢”通知根本没有被推送。
这是我在Parse的AnyPic教程之后建模的我的云代码（JavaScript）。我还有一个安装文件和一个指向这个和安装的“主”文件。我在这里缺少什么？
Parse.Cloud.beforeSave('Activity', function(request, response) {
var currentUser = request.user;
var objectUser = request.object.get('fromUser');
if(!currentUser || !objectUser) {
response.error('An Activity should have a valid fromUser.');
} else if (currentUser.id === objectUser.id) {
response.success();
} else {
response.error('Cannot set fromUser on Activity to a user other than the current user.');
}
});
Parse.Cloud.afterSave('Activity', function(request) {
// Only sends push notifications for new activities.
if (request.object.existed()) {
return;
}
var toUser = request.object.get("toUser");
if (!toUser) {
throw "Undefined toUser. Skipping push for Activity " + request.object.get('type') + " : " + request.object.id;
return;
}
var query = new Parse.Query(Parse.Installation);
query.equalTo('user', toUser);
Parse.Push.send({
where: query, // Set our Installation query.
data: alertPayload(request)
}).then(function() {
// Push was successful
console.log('Sent push.');
}, function(error) {
throw "Push Error " + error.code + " : " + error.message;
});
});
var alertMessage = function(request) {
var message = "";
if (request.object.get("type") === "comment") {
if (request.user.get('displayName')) {
message = request.user.get('displayName') + ': ' + request.object.get('content').trim();
} else {
message = "Someone left a comment on your photo.";
}
} else if (request.object.get("type") === "like") {
if (request.user.get('displayName')) {
message = request.user.get('displayName') + ' likes your photo.';
} else {
message = 'Someone likes your photo.';
}
}
// Trim our message to 140 characters.
if (message.length > 140) {
message = message.substring(0, 140);
}
return message;
}
var alertPayload = function(request) {
var payload = {};
if (request.object.get("type") === "comment") {
return {
alert: alertMessage(request), // Sets the alert message.
badge: 'Increment', // Increments the target device's badge count.
// The following keys help Cosplace to load the photo corresponding to this push notification.
p: 'a', // Payload Type: Activity
t: 'c', // Activity Type: Comment
fu: request.object.get('fromUser').id, // From User
pid: request.object.id // Photo Id
};
} else if (request.object.get("type") === "like") {
return {
alert: alertMessage(request), // Sets the alert message.
// The following keys help Cosplace to load the photo corresponding to this push notification.
p: 'a', // Payload Type: Activity
t: 'l', // Activity Type: Like
fu: request.object.get('fromUser').id, // From User
pid: request.object.id // Photo Id
};
}
}
谢谢！
编辑：这是AppDelagate.m文件中的Objective-C代码（我拿出了Parse ID）：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[Parse setApplicationId: @""
clientKey:@""];
[PFAnalytics trackAppOpenedWithLaunchOptions:launchOptions];
// Reset application icon badge number when app is launched.
if (application.applicationIconBadgeNumber != 0) {
application.applicationIconBadgeNumber = 0;
[[PFInstallation currentInstallation] saveInBackground];
}
// Registers the current device for push notifications.
UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert |
UIUserNotificationTypeBadge |
UIUserNotificationTypeSound);
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNotificationTypes categories:nil];
[application registerUserNotificationSettings:settings];
[application registerForRemoteNotifications];
if (application.applicationState != UIApplicationStateBackground) {
// Track an app open here if we launch with a push, unless
// "content_available" was used to trigger a background push (introduced
// in iOS 7). In that case, we skip tracking here to avoid double
// counting the app-open.
BOOL preBackgroundPush = ![application respondsToSelector:@selector(backgroundRefreshStatus)];
BOOL oldPushHandlerOnly = ![self respondsToSelector:@selector(application:didReceiveRemoteNotification:fetchCompletionHandler:)];
BOOL noPushPayload = ![launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (preBackgroundPush || oldPushHandlerOnly || noPushPayload) {
[PFAnalytics trackAppOpenedWithLaunchOptions:launchOptions];
}
}
// If the registration is successful, this callback method will be executed. This method informs Parse about this new device.
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
// Reset application icon badge number when app is launched.
if (application.applicationIconBadgeNumber != 0) {
application.applicationIconBadgeNumber = 0;
// Store the deviceToken in the current installation and save it to Parse.
PFInstallation *currentInstallation = [PFInstallation currentInstallation];
// [PFInstallation.currentInstallation setObject:PFUser.currentUser forKey:@"user"];
[currentInstallation setDeviceTokenFromData:deviceToken];
// Associate the device with a user
PFInstallation *installation = [PFInstallation currentInstallation];
installation[@"user"] = [PFUser currentUser];
[installation saveInBackground];
[currentInstallation saveInBackground];
// Create Parse Installation query
PFQuery *pushQuery = [PFInstallation query];
[pushQuery whereKey:@"deviceType" equalTo:@"ios"];
}
}
// So when logged out notifications stop being received.
- (void)logOut {
// Unsubscribe from push notifications by removing the user association from the current installation.
[[PFInstallation currentInstallation] removeObjectForKey:@"user"];
[[PFInstallation currentInstallation] saveInBackground];
}
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
[PFPush handlePush:userInfo];
[[NSNotificationCenter defaultCenter] postNotificationName:@"AppDelegateApplicationDidReceiveRemoteNotification" object:nil userInfo:userInfo];
}
- (void)applicationDidBecomeActive:(UIApplication *)application {
// Clear badge and update installation for auto-incrementing badges.
if (application.applicationIconBadgeNumber != 0) {
application.applicationIconBadgeNumber = 0;
[[PFInstallation currentInstallation] saveInBackground];
}
