示例Facebook目标代码。 [英] Example Facebook object code.
问题描述
这是从Facebook获取使用自定义对象的示例代码。我创建了一个自定义的动作来利用Facebook的故事。
Facebook文档：
https：/ /developers.facebook.com/docs/opengraph/overview/
This is the sample code i get from Facebook for the using custom objects. I created this with a custom action to make use of the Facebook story.
Facebook Documentation:
https://developers.facebook.com/docs/opengraph/overview/
NSMutableDictionary<FBGraphObject> *object =
[FBGraphObject openGraphObjectForPostWithType:@"sotd_facebook:new_zombie"
title:@"Sample New Zombie"
image:@"https://fbstatic-a.akamaihd.net/images/devsite/attachment_blank.png"
url:@"http://samples.ogp.me/191078581053171"
description:@""];;
[FBRequestConnection startForPostWithGraphPath:@"me/objects/sotd_facebook:new_zombie"
graphObject:object
completionHandler:^(FBRequestConnection *connection,
id result,
NSError *error) {
// handle the result
}];
我很好奇我如何使用这个对象在Facebook IOS sdk中的一个动作。
我尝试使用以下代码，并在创建FBRequestConnection时崩溃。
Im curious how can i use this object for an action in the Facebook IOS sdk. I have tried to use the following codes and it crash upon creating the FBRequestConnection.
[__NSCFBoolean dataUsingEncoding:]: unrecognized selector sent to instance 0x3af00530
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFBoolean dataUsingEncoding:]: unrecognized selector sent to instance 0x3af00530'
我已经创建了FBOpenGraphObject并使用FBRequestConnection方法startForPostOpenGraphObject：completionHandler。
在完成处理程序中，我从结果中检索id，并将其放在另一个带有id的FBOpenGraphObject中。
，它仍然崩溃。
[edit]
I have created FBOpenGraphObject and use FBRequestConnection method startForPostOpenGraphObject: completionHandler.
Within the completion handler, i retrieve the id from the result and put it in another FBOpenGraphObject with the id.
and it still crash.
NSMutableDictionary<FBOpenGraphObject> *object = [FBGraphObject
openGraphObjectForPostWithType:@"sotd_facebook:new_zombie"
title:@"Sample New Zombie"
image:@"https://fbstatic-a.akamaihd.net/images/devsite/attachment_blank.png"
url:@"http://samples.ogp.me/191078581053171"
description:@""];
[FBRequestConnection startForPostOpenGraphObject:object
completionHandler:^(FBRequestConnection *connection,
id result,
NSError *error) {
// handle the result
// handle the result
if (error)
{
NSLog(@"Error sharing story: %@", error.localizedDescription);
}
else if(result != nil)
{
NSLog(@"Result: %@", result);
NSString* resultID = [result objectForKey:@"id"];
NSMutableDictionary<FBOpenGraphObject> *newObject = [FBGraphObject openGraphObjectForPost];
newObject.id = resultID;
[FBRequestConnection startForPostWithGraphPath:@"me/objects/sotd_facebook:new_zombie"
graphObject:newObject completionHandler:^(FBRequestConnection *connection,
id result,
NSError *error) {
// handle the result
// handle the result
if (error)
{
NSLog(@"Error sharing story: %@", error.localizedDescription);
}
else
{
NSLog(@"Result: %@", result);
}
}];
}
}];

推荐答案
我在API调用之前添加了这些行，并且工作正常！
I just added these lines before API call and that works fine!
object[@"create_object"] = @"1";
object[@"fbsdk:create_object"] = @"1";
似乎这是Facebook SDK中的错误！它尝试编码布尔值
It seems this is a bug in Facebook SDK! it tries to encode Boolean value
示例代码应该是这样的
NSMutableDictionary<FBGraphObject> *object =
[FBGraphObject openGraphObjectForPostWithType:@"{YOUR NAMESPACE}:{YOUR OBJECT TYPE}"
title:@"title"
image:@"https://fbstatic-a.akamaihd.net/images/devsite/attachment_blank.png"
url:@"http://samples.ogp.me/192059197639963"
description:@"description"];
object[@"create_object"] = @"1";
object[@"fbsdk:create_object"] = @"1";
[FBRequestConnection startForPostWithGraphPath:@"me/objects/{YOUR NAMESPACE}:{YOUR OBJECT TYPE}"
graphObject:object
completionHandler:^(FBRequestConnection *connection,
id result,
NSError *error) {
NSLog(@"%@",result);
}];
}
