Question

我正在使用AFNetworking 1.2来创建一个显示用户推文的应用程序。该应用已成功验证用户身份，但未显示推文。以下是我收到推文的内容。

- (void)fetchTweets
{
    self.twitterClient = [[AFOAuth1Client alloc] initWithBaseURL:[NSURL URLWithString:@"https://api.twitter.com/1.1/"] key:@"4oFCF0AjP4PQDUaCh5RQ" secret:@"NxAihESVsdUXSUxtHrml2VBHA0xKofYKmmGS01KaSs"];

    [self.twitterClient authorizeUsingOAuthWithRequestTokenPath:@"/oauth/request_token" userAuthorizationPath:@"/oauth/authorize" callbackURL:[NSURL URLWithString:@"floadt://success"] accessTokenPath:@"/oauth/access_token" accessMethod:@"POST" scope:nil success:^(AFOAuth1Token *accessToken, id responseObject) {
        [self.twitterClient registerHTTPOperationClass:[AFJSONRequestOperation class]];
        [self.twitterClient getPath:@"statuses/user_timeline.json" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
            NSArray *responseArray = (NSArray *)responseObject;
            tweets = responseArray;
            [responseArray enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
                NSLog(@"Success: %@", obj);
            }];
        } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
            NSLog(@"Error: %@", error);
        }];
    } failure:^(NSError *error) {
        NSLog(@"Error: %@", error);
    }];
}

以下是我尝试将收到的推文加载到UITableView中的方法：

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"TweetCell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }

    NSDictionary *tweet = [tweets objectAtIndex:indexPath.row];
    NSString *text = [tweet objectForKey:@"text"];
    NSString *name = [[tweet objectForKey:@"user"] objectForKey:@"name"];

    cell.textLabel.text = text;
    cell.detailTextLabel.text = [NSString stringWithFormat:@"by %@", name];

    return cell;
}

我已经在Storyboard中添加了Cell Identifier，所以这不是问题。

Answer 1

[tableView reloadData];

在获取所有推文并将其分配给数组

后重新加载表

装置

- (void)fetchTweets
{
    self.twitterClient = [[AFOAuth1Client alloc] initWithBaseURL:[NSURL URLWithString:@"https://api.twitter.com/1.1/"] key:@"4oFCF0AjP4PQDUaCh5RQ" secret:@"NxAihESVsdUXSUxtHrml2VBHA0xKofYKmmGS01KaSs"];

    [self.twitterClient authorizeUsingOAuthWithRequestTokenPath:@"/oauth/request_token" userAuthorizationPath:@"/oauth/authorize" callbackURL:[NSURL URLWithString:@"floadt://success"] accessTokenPath:@"/oauth/access_token" accessMethod:@"POST" scope:nil success:^(AFOAuth1Token *accessToken, id responseObject) {
        [self.twitterClient registerHTTPOperationClass:[AFJSONRequestOperation class]];
        [self.twitterClient getPath:@"statuses/user_timeline.json" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
            NSArray *responseArray = (NSArray *)responseObject;
            tweets = responseArray;
            [tableView reloadData];
            //^ Add this line
            [responseArray enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
                NSLog(@"Success: %@", obj);
            }];
        } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
            NSLog(@"Error: %@", error);
        }];
    } failure:^(NSError *error) {
        NSLog(@"Error: %@", error);
    }];
}

注意：tableView是您的桌面视图名称

将Twitter推文加载到带有AFNetworking 1.2的UITableView中
