Question

我正在尝试将Twitter Feed显示到UITableView中。我能够获取feed和NSLog的信息。但是，我对如何显示信息而不是将其记录到控制台感到困惑。有人告诉我创建一个自定义对象，以便从feed中存储所需的数据，然后创建一个UITableVIew来显示信息，这就是我被卡住的地方。是否有任何建议或任何人都指出我正确的方向？以下是我的代码现在的样子。我感谢您的帮助，感谢您宝贵的时间。

以下代码：

#import "ViewController.h"
#import <Accounts/Accounts.h>
#import <Social/Social.h>

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad
{
    [self refreshTwitter];
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}



-(void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}




    -(void)refreshTwitter
    {
        ACAccountStore *accountStore = [[ACAccountStore alloc]init];

        if (accountStore != nil)
        {
            ACAccountType *accountType = [accountStore     accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
            if (accountType != nil)
            {
                [accountStore requestAccessToAccountsWithType:accountType options:nil completion:^(BOOL granted, NSError *error)
                 {
                     if (granted)
                     {
                         //Succesful Access
                         NSArray *twitterAccounts = [accountStore accountsWithAccountType:accountType];
                         if (twitterAccounts != nil)
                         {
                             ACAccount *currentAccount = [twitterAccounts objectAtIndex:0];
                             if (currentAccount != nil)
                             {
                                 NSString *requestString = @"https://api.twitter.com/1.1/statuses/user_timeline.json";
                                 SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodGET URL:[NSURL URLWithString:requestString] parameters:nil];
                                 [request setAccount:currentAccount];

                                 [request performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error)
                                 {
                                     if ((error == nil) && ([urlResponse statusCode] == 200))
                                     {
                                         NSArray *twitterFeed = [NSJSONSerialization JSONObjectWithData:responseData options:0 error:nil];
                                         NSDictionary *firstPost = [twitterFeed objectAtIndex:0];

                                         NSLog(@"firstPost = %@", [firstPost description]);
                                     }
                                 }];

                             }
                         }
                     }
                     else
                     {
                          //Access Denied
                     }

在类级别声明twitterFeed数组

<强> numberOfSectionsInTableView

-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
    return 1;
}

<强> numberOfRowsInSection

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

<强>的cellForRowAtIndexPath

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell" forIndexPath:indexPath];
    cell.textLabel = twitterFeed[indexPath.row][@"user"][@"screen_name"];
    return cell;
}
