How to send text and images using Facebook API in iPhone SDK? - iphone

Question

In my iPhone app, I want to send text as well as images to facebook.
Currently the facebook API suggest that there are seperate user permissions that enable us to do so.
Is there a way out where in I can do both using only one API in my project?
If Yes, How can we do so?
References to any articles or tutorials would be very helpful
Please Help & Suggest.
Thanks

Answer 1

Yes you can do this.
Please have a look at all the methods as below:
- (IBAction)uploadPhoto:(id)sender {
[self postOnFacebook];
}
//Post Message and Photo on Facebook Function
-(void)postOnFacebook
{
NSString *strPostMessage = [self createMessageForPostOnFacebook:74.112 withLongitude:21.85];
//UIImage *img = [[UIImage alloc] initWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:objClsProductSearch.strProductImageURL]]];
//UIImage *img = [[UIImage alloc] initWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:#"http://www.facebook.com/images/devsite/iphone_connect_btn.jpg"]]];
UIImage *img = [[UIImage alloc] initWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:#"http://d1xzuxjlafny7l.cloudfront.net/wp-content/uploads/2011/08/HUDTutorial.jpg"]]];
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
strPostMessage,#"message",img, #"source",
nil];
[_facebook requestWithGraphPath:#"/me/photos"
andParams:params
andHttpMethod:#"POST"
andDelegate:self];
[img release];
}
//Create Message for posting on Facebook
-(NSString *)createMessageForPostOnFacebook:(double)pfltLatitude withLongitude:(double)pfltLongitude
{
//NSString *urlString = [NSString stringWithFormat:#"http://maps.google.com/maps/geo?q=%f,%f&output=csv",pfltLatitude, pfltLongitude];
//NSString *urlString = [NSString stringWithFormat:#"http://maps.google.com/maps/geo?q=%f,%f&output=csv",#"", #""];
//NSError* error;
//NSString *locationString = [NSString stringWithContentsOfURL:[NSURL URLWithString:urlString] encoding:NSASCIIStringEncoding error:&error];
//NSArray *listItems = [locationString componentsSeparatedByString:#","];
NSString *strMessage = nil;
/*if([[listItems objectAtIndex:0] isEqualToString:#"200"])
{
strMessage = [NSString stringWithFormat:#"I found a %# using BH for iPhone \n Location : %# \n Latitude : %f & Longitude : %f \n Product Rating : %d",objClsProductSearch.strCategoryname,[locationString substringFromIndex:6],appDelegate.dblLatitude,appDelegate.dblLongitude,btnTmp.tag];
}*/
strMessage = [NSString stringWithFormat:#"I found a %# using BH for iPhone \n Location : %# \n Latitude : %f & Longitude : %f \n Product Rating : %d", #"Cat Name", #"Location", 74.112, 21.85, 1];
return strMessage;
}
I hope you will have success using the above code.
Let me know in case of any difficulty.
In you app delegate, have a look at below methods whether it is implemented or not.
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
//return [[controller facebook] handleOpenURL:url];
//return [[objPage2ViewController facebook] handleOpenURL:url];
return [[[self.navigationController topViewController] facebook] handleOpenURL:url];
}
Cheers

I'm not sure that it is possible. I've post image with next solution:
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
takedPhoto, #"picture",
#"some text", #"message",
nil];
[facebook requestWithGraphPath:#"/me/photos" andParams:params
andHttpMethod:#"POST" andDelegate:self];
takedPhoto is UIImage.
But it is only loading photos in photo album (and approve it if you allow permissions when logging in).
I don't know how can I post message on wall with this uploaded image...
