Hi All,
I have got a very frustrating problem. I am trying to upload video to youtube
using GData APIs and am having significant issues. I am sure one of you will
have done this previously and I hope you can assist me.
I have copied the cocoa sample and just put it in my code to get something
working I can customise it later. When this code executes it fails with the
following error
*** Assertion failure in -[GDataServiceBase
fetchObjectWithURL:objectClass:objectToPost:ETag:httpMethod:delegate:didFinishSelector:completionHandler:retryInvocationValue:ticket:](),
/Users/damien/damien/projects/google/gdata-objectivec-client-read-only/Source/BaseClasses/GDataServiceBase.m:559
*** Terminating app due to uncaught exception
'NSInternalInconsistencyException', reason: 'GDataHTTPUploadFetcher needed'
Ok so I go to the source of the assertion failure
//
// now that we have all the request header info ready,
// create and set up the fetcher for this request
//
GDataHTTPFetcher* fetcher = nil;
if (isUploadingDataChunked) {
// hang on to the user's requested chunk size, and ensure it's not tiny
NSUInteger uploadChunkSize = [self serviceUploadChunkSize];
if (uploadChunkSize < kMinimumUploadChunkSize) {
uploadChunkSize = kMinimumUploadChunkSize;
}
Class uploadClass = NSClassFromString(@"GDataHTTPUploadFetcher");
GDATA_ASSERT(uploadClass != nil, @"GDataHTTPUploadFetcher needed");
NSString *uploadMIMEType = [objectToPost uploadMIMEType];
fetcher = [uploadClass uploadFetcherWithRequest:request
uploadData:uploadData
uploadMIMEType:uploadMIMEType
chunkSize:uploadChunkSize];
} else {
fetcher = [GDataHTTPFetcher httpFetcherWithRequest:request];
}
So it appears the Class uploadClass =
NSClassFromString(@"GDataHTTPUploadFetcher"); line fails. This tells me that
there is no instance of the GDataHTTPUploadFetcher class at this time.
Ok so what did I miss in my method I can not find any definition of a
GDataHTTPUploadFetcher in the sample project.
I have provided my method below hoping someone can assist me by comparing mine
to theirs and showing me where I have gone wrong. I really appreciate your
assistance.
here is a stack trace also
