parse.com - Detect Facebook login failure -


i'm using pfloginviewcontroller subclass in app allow users login facebook works great, if user changes mind , denies app access facebook account, login stops working(as expected) loading indicator spins. never receive error telling me couldn't login, it's infinite loop.

any idea how detect failure , stop ui displaying loading indicator?

code below, straight subclassing visual tweaks.

 - (void)viewdidload {     [super viewdidload];      // customize default parse login view     [self setupui]; }  - (void)setupui {     [self.loginview setbackgroundcolor:[uicolor colorwithpatternimage:[uiimage imagenamed:@"bg"]]];     [self.loginview setlogo:[[uiimageview alloc] initwithimage:[uiimage imagenamed:@"fdbk_logo"]]];      // set buttons appearance     [self.loginview.facebookbutton setimage:nil forstate:uicontrolstatenormal];     [self.loginview.facebookbutton setimage:nil forstate:uicontrolstatehighlighted];     [self.loginview.facebookbutton setbackgroundimage:[uiimage imagenamed:@"fb_login_btn"] forstate:uicontrolstatenormal];     [self.loginview.facebookbutton settitle:@"" forstate:uicontrolstatenormal];     [self.loginview.facebookbutton settitle:@"" forstate:uicontrolstatehighlighted]; }

this isn't solution looking opinion:

i love parse stopped using built in controllers while ago (pflogin / signup, pfquerytableview etc) because whilst provide decent out-the-box functionality, they're bit incomplete use in production app. there many scenarios provide 90% of want (as in case now) , whilst save time compared rolling own, once make own have can customise want , re-use in future!
