我老老实实地花了几个小时试图让它发挥作用.不幸的是
Facebook&
App Link’s documentation还不够清楚.甚至是
App Links video from F8.
应用要求：
>分享FB作为Open Graph故事的链接,用户可以点击该故事将其直接带入我的应用程序并执行特定任务(我的应用程序需要从链接接收特定参数)
>在没有FB登录的情况下将链接共享到FB(即通过共享对话框并切换到本机iOS FB应用程序而不是使用API调用).
迄今取得的进展：
我正在使用以下代码来创建托管的应用程序链接(因为我只有移动内容),根据FB developer’s website under Publishing iOS SDK.
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys: @"{My app name}",@"name",{custom URL},@"al:iphone:url",@"{app store ID}",@"al:iphone:app_store_id",@"{My app name}",@"al:iphone:app_name",@"{\"should_fallback\": false}",@"web",fbAccesstoken,@"access_token",nil ]; /* make the API call */ [FBRequestConnection startWithGraPHPath:@"/{FB app id}/app_link_hosts" parameters:params HTTPMethod:@"POST" completionHandler:^( FBRequestConnection *connection,id result,NSError *error ) { /* handle the result */ NSLog(@"Result = %@",result); if(error) NSLog(@"error = %@",error); }];
接下来我将OG故事发布到FB(这是很好但没有正确的网址)
// Create OG object
id<FBGraphObject> object =
[FBGraphObject openGraphObjectForPostWithType:@"{app name}:{FB object_name}"
title:@"Test Link"
image:@"https://cdn3.iconfinder.com/data/icons/picons-social/57/56-apple-512.png" // hosted wallpaper with unique id for background
url:nil // Assuming I need to put the url to the app link host object here??
description:@"Click to on this test link!"];
// Create an action
id<FBOpenGraphAction> action = (id<FBOpenGraphAction>)[FBGraphObject graphObject];
// Link the object to the action
[action setobject:object forKey:@"{FB object name}"];
// Check if the Facebook app is installed and we can present the share dialog
FBOpenGraphActionParams *params = [[FBOpenGraphActionParams alloc] init];
params.action = action;
params.actionType = @"{app name}:{FB action name}";
// If the Facebook app is installed and we can present the share dialog
if([FBDialogs canPresentShareDialogWithOpenGraphActionParams:params]) {
// Show the share dialog
[FBDialogs presentShareDialogWithOpenGraphAction:action
actionType:@"{app name}:{FB action name}"
previewPropertyName:@"{FB object name}"
handler:^(FBAppCall *call,NSDictionary *results,NSError *error) {
if(error) {
// An error occurred,we need to handle the error
// See: https://developers.facebook.com/docs/ios/errors
NSLog(@"Error publishing story: %@",error.description);
} else {
// Success
NSLog(@"result %@",results);
}
}];
}
要在有人点击FB OG故事中的链接时处理传入的URL,我已根据FB文档将以下代码添加到AppDelegate.m – 请参阅Handling incoming links
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(Nsstring *)sourceApplication
annotation:(id)annotation {
BOOL urlWasHandled =
[FBAppCall handleOpenURL:url
sourceApplication:sourceApplication
fallbackHandler:
^(FBAppCall *call) {
// Parse the incoming URL to look for a target_url parameter
Nsstring *query = [url query];
NSDictionary *params = [self parseURLParams:query];
// Check if target URL exists
Nsstring *appLinkDataString = [params valueForKey:@"al_applink_data"];
if (appLinkDataString) {
NSError *error = nil;
NSDictionary *applinkData =
[NSJSONSerialization JSONObjectWithData:[appLinkDataString dataUsingEncoding:NSUTF8StringEncoding]
options:0
error:&error];
if (!error &&
[applinkData isKindOfClass:[NSDictionary class]] &&
applinkData[@"target_url"]) {
Nsstring *targetURLString = applinkData[@"target_url"];
// Show the incoming link in an alert
// Your code to direct the user to the
// appropriate flow within your app goes here
[[[UIAlertView alloc] initWithTitle:@"Received link:"
message:targetURLString
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil] show];
}
}
}];
return urlWasHandled;
}
// A function for parsing URL parameters
- (NSDictionary*)parseURLParams:(Nsstring *)query {
NSArray *pairs = [query componentsSeparatedByString:@"&"];
NSMutableDictionary *params = [[NSMutableDictionary alloc] init];
for (Nsstring *pair in pairs) {
NSArray *kv = [pair componentsSeparatedByString:@"="];
Nsstring *val = [[kv objectAtIndex:1]
stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
[params setobject:val forKey:[kv objectAtIndex:0]];
}
return params;
}
有没有人能够使这个工作？我还不清楚托管的App Link如何工作以及放置它的位置(我假设在调用FBGraphObject openGraphObjectForPostWithType方法时它应该放在’url’参数中.
我真的不想创建一个网站来存储所有的网址并添加App Link元标记(我必须通过应用程序完成所有这些,因为每个App Link都将是动态的,并且对于生成它的每个用户都是唯一的来自应用程序).
请帮忙！
解决方法
在FB的MingLi的帮助下,我设法使用以下代码：
- (void)sharetoOpenGraphCountdownInvite { NSURL *url = [NSURL URLWithString:@"https://graph.facebook.com/oauth/access_token?grant_type=client_credentials&client_id={insert your FB app ID here}&client_secret={insert client secret here}"]; Nsstring *fullToken = [Nsstring stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:nil]; NSArray *components = [fullToken componentsSeparatedByString:@"="]; FBAppAccesstoken = [components objectAtIndex:1]; NSDictionary *paramsForAppLinksHost = [NSDictionary dictionaryWithObjectsAndKeys: FBAppAccesstoken,@"{your app name}",@"{your app's custom url}",@"al:ios:url",@"al:ios:app_store_id",@"al:ios:app_name",nil ]; [FBRequestConnection startWithGraPHPath:@"/{FB app ID}/app_link_hosts" parameters:paramsForAppLinksHost HTTPMethod:@"POST" completionHandler:^( FBRequestConnection *connection,NSError *error ) { AppLinksHostURL_ID = [result objectForKey:@"id"]; // store this ID in an Nsstring [self postOGStoryWithCustomURL]; if(error) NSLog(@"error = %@",error.description); }]; } - (void)postOGStoryWithCustomURL { Nsstring *urlString = [Nsstring stringWithFormat:@"https://fb.me/%@/%@",AppLinksHostURL_ID,customURL]; UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:[self pathForS3ObjectWithFilename:previewImageFilename]]]]; // Create OG object id<FBGraphObject> object = [FBGraphObject openGraphObjectForPostWithType:@"timeflyz:countdown_invite" title:eventBeingShared.eventName image:image url:urlString // fb.me app links hosted url here description:@"{insert description here}"]; // Create an action id<FBOpenGraphAction> action = (id<FBOpenGraphAction>)[FBGraphObject graphObject]; // Link the object to the action [action setobject:object forKey:@"countdown_invite"]; // Check if the Facebook app is installed and we can present the share dialog FBOpenGraphActionParams *params = [[FBOpenGraphActionParams alloc] init]; params.action = action; params.actionType = @"timeflyz:create"; // If the Facebook app is installed and we can present the share dialog if([FBDialogs canPresentShareDialogWithOpenGraphActionParams:params]) { // Show the share dialog [FBDialogs presentShareDialogWithOpenGraphAction:action actionType:@"timeflyz:create" previewPropertyName:@"countdown_invite" handler:^(FBAppCall *call,NSError *error) { if(error) { // An error occurred,we need to handle the error // See: https://developers.facebook.com/docs/ios/errors NSLog(@"Error publishing story: %@",error.description); } else { // NSLog(@"result %@",results); if([[results objectForKey:@"completionGesture"] isEqualToString:@"post"]) { NSLog(@"Posted successfully!"); [[NSNotificationCenter defaultCenter] postNotificationName:@"showShareSuccessfullMessage" object:self userInfo:nil]; } else NSLog(@"Something else happened - user didn't post"); } }]; }
请注意,“customURL”是一个遵循模式“？variable1 = result1& variable2 = result2 …”的Nsstring.
