自定义单元格 - 我怎样才能将推特分割成 由 String 分隔的组件?
原标题:Custom cells - how can I separate out tweets into componentsseparatedbyString

我在表格视图中有一个自定义单元格。 所有连接都已经建立。 我正在进行推特搜索。 此搜索的结果在表格View中传播自定义单元格。 我想将个人发来的推文用组件分隔成一个阵列, 这样我就可以在自定义单元格中指定4个标签。 任何帮助都会非常感激。 这是我的代码 。

    - (void)fetchTweets
    {
        dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
            NSData* data = [NSData dataWithContentsOfURL:
                            [NSURL URLWithString: @"https://api.twitter.com/1/statuses/public_timeline.json"]];

            NSError* error;

            tweets = [NSJSONSerialization JSONObjectWithData:data
                                                     options:kNilOptions
                                                       error:&error];

            dispatch_async(dispatch_get_main_queue(), ^{
                [self.tableView reloadData];
            });
        });
    }

    - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
    {
        return tweets.count;

    }

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

        customCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
        if (cell == nil) {
                // added this bit in
            cell = [[customCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];


        }

       // THIS IS THE BIT I M STRUGGLING WITH
// I M GUESSING THAT THIS LINE SEPARATES THE TWEETS INTO SINGLE TWEETS?
        NSDictionary *tweet = [tweets objectAtIndex:indexPath.row];
// I THEN CREATE AN ARRAY TO HOLD MY COMPONENTS OF THE TWEET SO THAT I CAN SPLIT FOR MY LABELS
        NSArray *arrayForCustomCell = [[NSArray alloc] init];

        arrayForCustomCell = [tweet componentsSeparatedByString:@":"];





        return cell;
    }
最佳回答

您已经在您的非同步调用中解析了结果 。 现在, 您有一系列推文字典, 您可以抓住任何这样的值 :

NSDictionary *tweet = [tweets objectAtIndex:indexPath.row];
NSString *tweetText = [tweet valueForKey:@"text"];
NSString *tweetCountry = [tweet valueForKeyPath:@"place.country"] //Nested property

然后设置您的 UILabels 。你明白...
