如何在iOS中将带有图像的位置发布到Facebook? [英] How to post location with image to facebook in IOS?

问题描述

我正在尝试将位置以及图片分享到Facebook.我已成功共享图像，但无法共享位置.下面是我分享图片的代码.

I am trying to share location along with image to facebook. I have successfully shared image but unable to share location. Below is my code of sharing image.

UIImage *facebookImage = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@%@",imagesURL,str]]]];
NSMutableDictionary* params = [[NSMutableDictionary alloc] init];
[params setObject:@"New Happening created on the HappenShare mobile app." forKey:@"message"];
[params setObject:facebookImage forKey:@"picture"];
[FBRequestConnection startWithGraphPath:@"me/photos" parameters:params HTTPMethod:@"POST" completionHandler:^(FBRequestConnection *connection,id result,NSError *error)
{
    if (error)
    {
        NSLog(@"error : %@",error);
    }
    else
    {
        NSLog(@"Result : %@",result);
    }
}];

现在要共享位置，我应该在上面的代码中添加什么参数.我还要附加一个图像，以更好地了解共享位置的样子.下图显示了带有文本的图像如何指示地图中的位置.请为我提出解决方案.

Now for sharing location what parameter should I add in above code. I am attaching an image also to understand better that how the shared location will look like.Below image shows that how the image with text will indicate a location into map. Please suggest me a solution for that.

推荐答案

连同消息"，您还需要地方" ID才能作为参数发布.

Along with "message" and you also need "place" ID to post as param.

请求发布动作"，以便您可以发布地点/位置.

Request for a "publish_actions" so that you can post a place/location.

以下是我使用的代码:

NSMutableDictionary *params = [NSMutableDictionary dictionary];
                    [params setObject:@"Hello World" forKey:@"message"];
                    [params setObject:@"110503255682430"/*sample place id*/ forKey:@"place"];
[[[FBSDKGraphRequest alloc] initWithGraphPath:@"/me/feed" parameters:params HTTPMethod:@"POST"] startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
                        NSLog(@"result %@",result);
                        NSLog(@"error %@",error);
 }];

您还可以使用开发者"页面->您的应用->角色中提供的管理员/测试者"帐户进行检查. 使用图资源管理器进行更好的练习: https://developers.facebook.com/tools/explorer/108895529478793?method=POST&path=me%2Ffeed%3F&version=v2.5&message=Hello%20world&place=110503255682430

You can also check this with the "administrator/tester" accounts given in Developer page -> your app -> Roles. Use Graph explorer for better practice: https://developers.facebook.com/tools/explorer/108895529478793?method=POST&path=me%2Ffeed%3F&version=v2.5&message=Hello%20world&place=110503255682430

以下代码可以帮助您获取您所在位置附近的地点ID:

Below code may help you in getting place id near your location:

NSMutableDictionary *params2 = [NSMutableDictionary dictionaryWithCapacity:4L];
  [params2 setObject:[NSString stringWithFormat:@"%@,%@",YourLocation latitude,YourLocation longitude] forKey:@"center"]; //Hard code coordinates for test
  [params2 setObject:@"place" forKey:@"type"];
  [params2 setObject:@"100"/*meters*/ forKey:@"distance"];

 [[[FBSDKGraphRequest alloc] initWithGraphPath:@"/search" parameters:params2 HTTPMethod:@"GET"] startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
                    NSLog(@"RESPONSE!!! /search");
}];

OR

[[[FBSDKGraphRequest alloc] initWithGraphPath:@"/search?type=place&center=YourLocationLat,YourLocationLong&distance=500" parameters:nil HTTPMethod:@"GET"] startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
                    NSLog(@"result %@",result);
}];
