I'm playing with the object-c API (Gdata) of google to interact with youtube (in my case) but i'm running into a problem. I'm trying to search a youtube video with the query class:
NSURL *feedURL = [GDataServiceGoogleYouTube youTubeURLForFeedID:nil];
GDataQueryYouTube *query = [GDataQueryYouTube youTubeQueryWithFeedURL:feedURL];
[query setVideoQuery:#"\"Fred Flintstone\""];
ticket = [service fetchFeedWithQuery:query
delegate:self
didFinishSelector:#selector(entryListFetchTicket:finishedWithFeed:)];
[ticket setShouldFollowNextLinks:NO];
But when i execute it i have this error in the consol (the call back entryListFetchTicket is not even called)

I have no idea why...
But in the othr hand if i uses feed it works...
NSURL *feedURL;
feedURL = [GDataServiceGoogleYouTube youTubeURLForFeedID:kGDataYouTubeFeedIDMostPopular];
ticket = [service fetchFeedWithURL:feedURL
delegate:self
didFinishSelector:#selector(entryListFetchTicket:finishedWithFeed:error:)];
[ticket setShouldFollowNextLinks:NO]
Can somebdoy give me a hand ?
Thanks
Do you actually define a method entryListFetchTicket:finishedWithFeed: in your class that you are using as the delegate object?
The callbacks for GData fetches have three parameters, not two. The first code snippet is missing the error: at the end of the selector.
Be sure to define DEBUG=1 for your debug builds; the library will catch such issues.

}
}
Please help me fix the same. Thank you.
Basically you're calling bannerViewDidLoadAd: with the wrong object type. It appears that you're using some sort of dispatch mechanism to do this. Either you specified the wrong object when you set up the dispatch request for that method, or you failed to retain the object and it's been deleted and replaced with a NSType object.
So find where bannerViewDidLoadAd: is mentioned in your code and make sure the object being used with it is correct and is appropriately retained.
bannerViewDidLoad is getting called after it's delegate is released, hence the zombie message.
I would guess that this means your ad isn't being released and is sticking around after your controller is going away.
I have a table view in which Iam selecting a row of the table view and then it hits the web services, retrieves data and then displayed. Now this is my error log Iam getting.

Kindly suggest me what should i do.
You're sending the message setDownloadedLogoImage: to an NSData object, which has no idea what to do with it! One of two things has happened:
1) You have not retained something. Take a look at whatever object you expect to call setDownloadedLogoImage on and find out where you create it - you should probably be retaining it there ;)
2) (less likely) Your code is just wrong! Add it to your question and we can take a look.

The important line is :

It means you are calling count on a string. The object you think is an array is actually a string.
From looking at your code, tempArr could be either an array or a string. Try this:
if ([tempArr isKindOfClass:[NSArray class]])
{
// Handle array case
}
else if ([tempArr isKindOfClass:[NSString class]])
{
// Handle string case
}
It's probably a good idea to change the name of tempArr to something else, like tempResponse or similar.

this shows you are calling a function which is not a member function of NSXMLParser class.
actually in your code you are calling any method which can not be invoke on the obeject of NSXMLParser class.
chechk by debugging pointer.
I just suffered from this same issue. For me the problem was caused by this line of code:
operation.responseSerializer = [AFXMLParserResponseSerializer serializer];
This serialised the responseObject I was passing into the parser to XML but the parser expects an NSData object. Simply getting rid of that line solved the problem.
I also faced the similar problem.
Fixed by changing my line
self.xmlParser = [[NSXMLParser alloc] initWithData:data];
to
self.xmlParser = (NSXMLParser *)responseObject;
I found my solution from this blog
Raywanderlick Blog
Explanation for Error
This configuration of [AFXMLParserResponseSerializer serializer] already return an initialized object and I was initializing it again using already initialized parser by considering it data object.
Commenting following line didn't work for me as suggested by #Hodson answer above and it doesn't make sense as this is default configuration of AFTNetworking library.
operation.responseSerializer = [AFXMLParserResponseSerializer serializer];

terminate called after throwing an instance of 'NSException'
How would I fix this? Thanks.
Set a breakpoint on objc_exception_throw, then build the app for debug, run the app with breakpoints on and cause the crash again, then go up the stack to the relevant code.
Something inside SHKOAuthView webView:shouldStartLoadWithRequest:navigationType: is passing a nil argument to NSString rangeOfString. When you know what is passing the nil, it may be obvious what the problem is - failing that update your question with the relevant code and any extra information you've determined.
