POiOS delegate issues with KVO
text
Body
copied!<p>I have a method which sends out a request and has a delegate responder. The method is being called by a KVO responder. The code works fine when I call it from viewDidLoad, but when I make the request from the KVO method, it doesn't trigger the delegate method.</p> <p>here is my KVO responder:</p> <pre><code>//observe app delegates userdata to check for when user data is available or data is changed - (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { if ([keyPath isEqualToString:@"userData"] ) { //goto facebook logic [self FBFriendSuggester]; } } </code></pre> <p>and the method it calls:</p> <pre><code>-(void)FBFriendSuggester { NSDictionary * fb_credentials = nil; if([prefs objectForKey:@"facebookCredentials"]) { fb_credentials = [prefs objectForKey:@"facebookCredentials"]; if ([fb_credentials objectForKey:@"expiry"] && [fb_credentials objectForKey:@"fbtoken"]) { NSLog(@"found stored Facebook credentials."); ApplicationDelegate.facebook.accessToken = [fb_credentials objectForKey:@"fbtoken"]; ApplicationDelegate.facebook.expirationDate = [fb_credentials objectForKey:@"expiry"]; } } if ([ApplicationDelegate.facebook isSessionValid]) { printf("_valid facebook\n"); [ApplicationDelegate.facebook requestWithGraphPath:@"me/friends" andDelegate:self]; }else printf("_invalid facebook\n"); } </code></pre> <p>and the delegate method:</p> <pre><code>- (void)request:(FBRequest *)request didLoad:(id)result{ NSLog(@"result2:%@",result); NSDictionary * rawObject = result; NSArray * dataArray = [rawObject objectForKey:@"data"]; for (NSDictionary * f in dataArray) { [friends addObject:[[KNSelectorItem alloc] initWithDisplayValue:[f objectForKey:@"name"] selectValue:[f objectForKey:@"id"] imageUrl:[NSString stringWithFormat:@"http://graph.facebook.com/%@/picture?type=square", [f objectForKey:@"id"]]]]; } [friends sortUsingSelector:@selector(compareByDisplayValue:)]; [self pickerPopup:self]; } </code></pre> <p>the delegate method doesn't get called in this scenario, but it does work fine when i call -(void)FBFriendSuggester directly from the controller. I don't know what to do, i tried setting a notification to respond in hopes that it would trigger the delegate, but that didn't work either.</p>
