Ios UITableViewCells不'；不接受自定义值

我正在尝试使用

UITableView

和一些JSON对象制作一个项目提要， 但是当我尝试用JSON数据填充自定义单元格的实例时，

UILabel

s不会更改它们的文本

JSON已经过测试，可以正常工作。它通过循环并创建适当数量的行。但是文本不会更改为JSON文件中的文本

这是我的密码：

feed.m

- (void)viewDidLoad {
    [super viewDidLoad];

    NSURL *FeedURL = [NSURL URLWithString:@"http://www.personeelsapp.jordivanderhek.com/company/bijcasper/nieuws.json"];
    NSData *jsonData = [NSData dataWithContentsOfURL:FeedURL];
    NSError *error = nil;
    NSDictionary *dataDictionary = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error:&error];

    NSLog(@"%@", dataDictionary);

    self.posts = [NSMutableArray array];
    PostsArray = [dataDictionary objectForKey:@"feed"];

    for (NSDictionary *bpdDictionary in PostsArray) {
        // make new post object
        FeedPosts *posts = [FeedPosts InitPost];
        NSLog(@"feed check %@" ,[bpdDictionary objectForKey:@"name"]);
        posts.postTitle = [bpdDictionary objectForKey:@"name"];
        posts.postProfilepic = [bpdDictionary objectForKey:@"profilePic"];
        posts.postDatum = [bpdDictionary objectForKey:@"timeStamp"];
        posts.postMessage = [bpdDictionary objectForKey:@"status"];
        posts.postImage = [bpdDictionary objectForKey:@"image"];
        [self.posts addObject:posts];
    }
}

已收到以下错误：

-[__NSCFString text]: unrecognized selector sent to instance

我做错了什么？

您在feedpost中声明了几个UILabel

在以下代码中，将NSString（文本）指定给label对象：

FeedPosts *posts = [FeedPosts InitPost];
NSLog(@"feed check %@" ,[bpdDictionary objectForKey:@"name"]);
posts.postTitle = [bpdDictionary objectForKey:@"name"];

相反，您应该设置这些标签的文本：

posts.postTitle.text = [bpdDictionary objectForKey:@"name"];

---

postMessage

和

postdatam

显示新文本单元格设置的代码在哪里？请将缺少的代码添加到

tableView:cellforrowatinexpath:

方法中。加载数据后，需要在表上调用

reloadData

，因为现在没有任何代码。因为我试图在

viewdidload

方法中的for循环中执行此操作@RoboticCat@JordivanderHek嗯？您需要在

cellforrowatinexpath

方法中创建、设置并返回一个单元格。显示该代码。@rmaddy我无法在cellForRowAtIndexPath中重新定义任何内容“单元格”没有任何可用于链接到我的标签的属性
