我想實現評論與gdata-objectivec-client庫YouTube視頻,使用的代碼片段張貼在this thread;拷貝如下:發佈評論失敗
- (void)addCommentTitle:(NSString *)commentTitle
text:(NSString *)commentContent
toVideo:(GDataEntryYouTubeVideo *)entry {
GDataComment *commentObj = [entry comment];
GDataFeedLink *feedLink = [commentObj feedLink];
NSURL *feedURL = [feedLink URL];
if (feedURL) {
// fetch the comment feed for the video
GDataServiceGoogleYouTube *service = [self youTubeService];
[service fetchFeedWithURL:feedURL
completionHandler:^(GDataServiceTicket *ticket, GDataFeedBase *commentFeed, NSError *error) {
// callback
//
// insert a new comment into the comment feed
if (error == nil) {
GDataEntryYouTubeComment *newCommentEntry = [GDataEntryYouTubeComment commentEntry];
[newCommentEntry setTitleWithString:commentTitle];
[newCommentEntry setContentWithString:commentContent];
NSURL *postURL = [[commentFeed postLink] URL];
[service fetchEntryByInsertingEntry:newCommentEntry
forFeedURL:postURL
completionHandler:^(GDataServiceTicket *ticket, GDataEntryBase *entry, NSError *error) {
// callback
if (error == nil) {
// succeeded
}
}];
}
}];
}
}
,但我總是得到以下異常:
*** Assertion failure in -[GDataObject setContentStringValue:](), XXXXXXXX/GData/BaseClasses/GDataObject.m:2353
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'GDataEntryYouTubeComment setting undeclared content value'
幸運的是,我設法讓這個消失,加入一個新的呼叫發言內容設置前:
GDataEntryYouTubeComment* newCommentEntry = [GDataEntryYouTubeComment commentEntry];
[newCommentEntry addContentValueDeclaration]; // <--- this method does the trick
[newCommentEntry setTitleWithString:commentTitle];
[newCommentEntry setContentStringValue:commentContent];
,但它仍然是不正常的請求,現在從與此錯誤的服務器反彈:
serviceBase:<GDataServiceGoogleYouTube: 0x7a73eb0>
objectFetcher:GTMHTTPFetcher 0x7c75b20 (https://gdata.youtube.com/feeds/api/videos/XXXXXXXXXX/comments)
failedWithStatus:400
data:<errors xmlns='http://schemas.google.com/g/2005'><error><domain>GData</domain><code>ParseException</code><internalReason>[Line 2, Column 514, element entry] No converter for type class java.lang.Void</internalReason></error><error><domain>GData</domain><code>missingConverter</code><internalReason>No converter for type class java.lang.Void</internalReason></error></errors>
有沒有其他人遇到過這個問題?這是我的錯誤還是Google的錯誤?
非常感謝,官方文件真的讓我失望;-) – 2012-10-25 14:34:43
