iOS中的Facebook共享对话框

问题描述

我正在试图在示例应用程序中从Facebook实施

I am trying to implement the native Share dialog from Facebook in a sample application.

似乎有一些问题这样做。

Seem to have some problem in doing so.

到目前为止我已经做的事情：

Things I have done so far:

1. 包含最新的Facebook SDK


2. 包括AdSupport，Social，Account，Security和libsqlite3.dylib。 / li>
   
3. 从Facebook添加示例代码。


4. 将-lsqlite3.0 -ObjC添加到其他链接器标志


5. 将应用程序ID添加到plist


6. 将FBUserSettingsViewResources包和FacebookSDKResources.bundle添加到项目中

1. Included the latest Facebook SDK
2. Included the AdSupport, Social, Account, Security and libsqlite3.dylib.
3. Added the sample code from Facebook.
4. Added -lsqlite3.0 -ObjC to Other Linker Flags as well
5. Added the app id to the plist
6. Added the FBUserSettingsViewResources bundle and FacebookSDKResources.bundle to the project

但我似乎不能共享URL。共享对话框甚至不会出现。

But I can't seem to share the URL. The share dialog doesn't even appear.

我的代码如下所示：

Viewcontroller.h

Viewcontroller.h

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController
{
    IBOutlet UIButton *buttonShare;
}
- (IBAction)shareButtonClicked:(id)sender;
@end

ViewController.m

ViewController.m

#import "ViewController.h"
#import <FacebookSDK/FacebookSDK.h>

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}



- (IBAction)shareButtonClicked:(id)sender
{
    FBShareDialogParams *params = [[FBShareDialogParams alloc] init];
    params.link = [NSURL URLWithString:@"https://developers.facebook.com/ios"];
    params.picture = [NSURL URLWithString:@"https://raw.github.com/fbsamples/ios-3.x-howtos/master/Images/iossdk_logo.png"];
    params.name = @"Facebook SDK for iOS";
    params.caption = @"Build great apps";
    [FBDialogs presentShareDialogWithParams:params clientState:nil handler:^(FBAppCall *call, NSDictionary *results, NSError *error) {
        if(error) {
            NSLog(@"Error: %@", error.description);
        } else {
            NSLog(@"Success!");
        }
    }];
}
@end

无法共享网址。需要一些指导。

Not able to share the URL. Need some guidance on this.

- (IBAction)shareButtonClicked:(id)sender
{
    // if the session is closed, then we open it here, and establish a handler for state changes

    [FBSession openActiveSessionWithReadPermissions:nil allowLoginUI:YES completionHandler:^(FBSession *session,FBSessionState state, NSError *error)
     {
         if (error)
         {
             UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error" message:error.localizedDescription delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
             [alertView show];
         }
         else if(session.isOpen)
         {
             NSString *str_img = [NSString stringWithFormat:@"https://raw.github.com/fbsamples/ios-3.x-howtos/master/Images/iossdk_logo.png"];

             NSDictionary *params = @{
                                      @"name" :[NSString stringWithFormat:@"Facebook SDK for iOS"],
                                      @"caption" : @"Build great Apps",
                                      @"description" :@"Welcome to iOS world",
                                      @"picture" : str_img,
                                      @"link" : @"",
                                      };

             // Invoke the dialog
             [FBWebDialogs presentFeedDialogModallyWithSession:nil
                                                    parameters:params
                                                       handler:
              ^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
                  if (error) {
                      //NSLog(@"Error publishing story.");
                      [self.indicator stopAnimating];
                  } else {
                      if (result == FBWebDialogResultDialogNotCompleted) {
                          //NSLog(@"User canceled story publishing.");
                          [self.indicator stopAnimating];
                      } else {
                          //NSLog(@"Story published.");
                          [self.indicator stopAnimating];
                      }
                  }}];
         }

     }];

    return;
}
