Post an image on my own Facebook wall with Facebook SDK 3.0 (beta), Xcode 4.3.2
提问by Sébastien Xcode
I am using Facebook SDK 3.0 (with Xcode 4.3.2 also and with ARC disabled), I already wrote the codes for login and post a text message on my own Facebook wall (codes above), everything run perfectly :
我正在使用 Facebook SDK 3.0（也使用 Xcode 4.3.2 并且禁用了 ARC），我已经编写了登录代码并在我自己的 Facebook 墙上发布了一条短信（上面的代码），一切运行完美：
- (IBAction)loginFacebook:(id)sender {
// Initiate a Facebook instance
Facebook *facebook = [[Facebook alloc] initWithAppId:@"My_App_ID" andDelegate:nil];
// Set the session information for the Facebook instance
facebook.accessToken = self.session.accessToken;
facebook.expirationDate = self.session.expirationDate;
// Put together the dialog parameters
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
@"I'm using Emoji-Smileys", @"name",
@"Facebook for iOS", @"caption",
@"Check out the application Emoji-Smileys for iOS to enable emoji keyboard, and make fun messages! There are 460 smileys!", @"description",
@"http://m.facebook.com/apps/hackbookios/", @"link",
@"http://a365.phobos.apple.com/us/r30/Purple/v4/fa/96/4c/fa964c2a-3a48-4f6d-7789-d3105a392a9f/mzl.evuvwyjk.png?downloadKey=1343552764_471c078e9d07fde2b00bd3f1ee1d88a7", @"picture",
nil];
// Invoke the dialog
[facebook dialog:@"feed" andParams:params andDelegate:self];
}
- (FBSession *)createNewSession
{
self.session = [[FBSession alloc] init];
return self.session;
}
- (void)sessionStateChanged:(FBSession *)session
state:(FBSessionState) state
error:(NSError *)error
{
switch (state) {
case FBSessionStateOpen:
if (!error) {
// We have a valid session
NSLog(@"User session found");
}
break;
case FBSessionStateClosed:
case FBSessionStateClosedLoginFailed:
[session closeAndClearTokenInformation];
self.session = nil;
[self createNewSession];
break;
default:
break;
}
if (error) {
UIAlertView *errorAlert = [[UIAlertView alloc]
initWithTitle:@"Error"
message:error.localizedDescription
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[errorAlert show];
}
}
- (void) openSession {
[self.session openWithCompletionHandler:
^(FBSession *session, FBSessionState state, NSError *error) {
[self sessionStateChanged:session state:state error:error];
}];
}
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation
{
return [self.session handleOpenURL:url];
}
Okay, now, I'd like to know how to post an image that I give in my application, no need to use the UIImagePickerViewController, I don't want to select the image. I don't know if I need a publish_stream, read_stream or user_likes permission or other thing.
好的，现在，我想知道如何发布我在应用程序中提供的图像，不需要使用 UIImagePickerViewController，我不想选择图像。我不知道我是否需要 publish_stream、read_stream 或 user_likes 权限或其他东西。
Thanks in advance for your help.
在此先感谢您的帮助。
Cheers.
干杯。

You can use this code, which helped me:
您可以使用此代码，它对我有帮助：
[FBRequestConnection startForUploadPhoto:myImg.image
completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
if (!error) {
// is success do something...
} else {
// If some error , do something...
}
}];
myImgis your image which you can replace with:
myImg是您可以替换为的图像：
[UIImage imageNamed:@"image.jpg"]
