I try to use Facebook’s Feed Dialog. According to the examples on the Facebook Developer’s web pages I coded two classes MyAppModelClass<\/em> and MyViewCntrl<\/em>, see below.<\/p>\n

Compilation runs without errors or warnings! And the iOS app hangs only the first time it is ran.<\/p>\n

When I call [MyViewCntrl aMethod]<\/em> the first time<\/strong> – The user has to login with eMail and password – After login posting to the users wall can be edited<\/p>\n

– After clicking “share” button on the feed dialog I get a grey view displayed and the iOS app hangs.<\/p>\n

The view shows text that says:<\/p>\n

\nwindow.location.href=\"fbconnect:\\\/\\\/success?\npost_id=_253268854729889#_=_\";\n\n<\/code><\/pre>\n
I thing the second number at post_id is a access token, but I am not sure.<\/p>\n
    \n
  • I do not<\/strong> get a NSLog from one of the FBDialofDelegate’s
    \nmethods, ([MyAppModelClass dialogDidComplete]<\/em>, [MyAppModelClass dialogDidNotComplete]<\/em>, .) at console!<\/li>\n
  • The posting appears at the users wall<\/li>\n<\/ul>\n
    If I stop the iOS app in the iphone simulator (home button) and i Xcode (stop button) and then restart the app on the iPhone simulator I do not get asked for authentication. And I do not<\/strong> get this javascript returned, everything works fine then.<\/p>\n
    What can I do to handle, avoid or get rid of the javascript returned during the first run?<\/p>\n
    See code outline below …<\/p>\n
    MyAppModelClass.h<\/strong><\/p>\n
    #import \"Facebook.h\"\n#import \"FBConnect.h\"\n#import \"FBDialog.h\"\n\n@interface MyAppModelClass :  NSObject   {\n\n@property (nonatomic, retain) Facebook* facebook;\n}\n<\/code><\/pre>\n
    MyAppModelClass.m<\/strong><\/p>\n
    #import \"MyAppModelClass.h\"\n\n@synthesize facebook;\n\n\n#pragma mark -\n#pragma mark FBDialogDelegate\n\n\n- (void) dialogDidComplete: (FBDialog*) dialog {\n   NSLog(@\".dialogDidComplete: %@\", dialog);\n}\n\n\n- (void) dialogCompleteWithUrl:(NSURL*) url {\n   NSLog(@\".dialogDidCompleteWithURL: %@\", url);\n}\n\n\n- (void) dialogDidNotComplete:(FBDialog*) dialog {\n   NSLog(@\".dialogDidNotComplete: %@\", dialog);\n}\n\n- (void)dialogDidNotCompleteWithUrl:(NSURL*) url {\n    NSLog(@\".dialogDidNotCompleteWithUrl: %@\", url);\n}\n\n\n- (void)dialog:(FBDialog*)dialog didFailWithError:(NSError*) error{\n    NSLog(@\".didFailWithError: %@\", dialog);\n\n}\n<\/code><\/pre>\n
    MyViewCntrl.h<\/strong><\/p>\n
    #import \"MyAppModelClass.h\"\n\n- (void) aMethod;\n<\/code><\/pre>\n
    MyViewCntrl.m<\/strong><\/p>\n
    #import \"MyViewCntrl.h\"\n\n\n- (void) aMethod {\nNSMutableDictionary* myParameters = [[NSMutableDictionary alloc];\n          initWithObjectsAndKeys: @\"1234567\", @\"app_id\",  \n                                    @\"touch\", @\"display\",\n     @\"http:\/\/myWebSite.de\/pics\/AppIcon.jpg\", @\"picture\",\n                      @\"http:\/\/myWebSite.de\", @\"link\",  \n                         @\"It's my web site\", @\"caption\",\n               @\"Visit my personal web site\", @\"description\",\n                                    @\"false\", @\"show_error\", nil];\n\n[ptrMyAppModelClass facebook] dialog: @\"feed\"\n                           andParams: myParameters\n                         andDelegate: ptrMyAppModelClass];\n}\n<\/code><\/pre>\n
