最初我需要能夠使用twitter與搜索API。我用Matt Gemmell的偉大的MGTwitterEngine做了這個。該代碼是非常非常簡單,看起來是這樣的:在iPhone上使用Twitter上的Twitter + OAuth搜索
- (void)viewDidLoad {
[super viewDidLoad];
tweetArrays = nil;
tweetNameArray = nil;
NSString *username = @"<username>";
NSString *password = @"<password>";
NSString *consumerKey = @"<consumerKey>";
NSString *consumerSecret = @"<consumerSecret>";
// Most API calls require a name and password to be set...
if (! username || ! password || !consumerKey || !consumerSecret) {
NSLog(@"You forgot to specify your username/password/key/secret in AppController.m, things might not work!");
NSLog(@"And if things are mysteriously working without the username/password, it's because NSURLConnection is using a session cookie from another connection.");
}
// Create a TwitterEngine and set our login details.
twitterEngine = [[MGTwitterEngine alloc] initWithDelegate:self];
[twitterEngine setUsesSecureConnection:NO];
[twitterEngine setConsumerKey:consumerKey secret:consumerSecret];
// This has been undepreciated for the purposes of dealing with Lists.
// At present the list API calls require you to specify a user that owns the list.
[twitterEngine setUsername:username];
[twitterEngine getSearchResultsForQuery:@"#HelloWorld" sinceID:0 startingAtPage:1 count:100];
}
這最終會調用該函數:
- (void)searchResultsReceived:(NSArray *)searchResults forRequest:(NSString *)connectionIdentifier
然後,我可以做我想做與SearchResult所。這需要我包括yajl庫。
然後,我想擴展我的代碼,以允許用戶鳴叫。我下載了Ben Gottlieb的偉大代碼Twitter-OAuth-iPhone
所以只有一個問題。該getSearchResultsForQuery返回requestFailed,出現以下錯誤:
Error Domain=HTTP Code=400 "The operation couldn’t be completed. (HTTP error 400.)"
要調用這個代碼,我只是參加了Twitter的OAuth的iPhone示範項目,並添加到getSearchResultsForQuery呼叫如下所示:
- (void) viewDidAppear: (BOOL)animated {
if (_engine) return;
_engine = [[SA_OAuthTwitterEngine alloc] initOAuthWithDelegate: self];
_engine.consumerKey = kOAuthConsumerKey;
_engine.consumerSecret = kOAuthConsumerSecret;
UIViewController *controller = [SA_OAuthTwitterController controllerToEnterCredentialsWithTwitterEngine: _engine delegate: self];
if (controller)
[self presentModalViewController: controller animated: YES];
else {
[_engine getSearchResultsForQuery:@"HelloWorld"];
// [_engine sendUpdate: [NSString stringWithFormat: @"Already Updated. %@", [NSDate date]]];
}
}
如上所述,返回400錯誤。我在此處添加的每個其他Twitter API函數都會執行以下操作:
- (NSString *)getRepliesStartingAtPage:(int)pageNum;
我做錯了什麼?或者getSearchResultsForQuery不再有效?這兩個代碼庫似乎使用不同版本的MGTwitterEngine,可能會導致問題?
謝謝!
