UITableview NSarray isEqualToString無法識別的選擇器發送到實例

我試圖在UITableview中顯示我的記錄。我可以得到json數據。問題開始於UITableViewCell。UITableview NSarray isEqualToString無法識別的選擇器發送到實例

-(void)getData { 
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; 
    manager.responseSerializer = [AFHTTPResponseSerializer serializer]; 
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; 
    [dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"]; 
    NSString *dateString; 
    dateString = [dateFormatter stringFromDate:[NSDate date]]; 
    NSDictionary *params = @{@"tarih":dateString,@"email":@"[email protected]",@"token":@"token",@"id":@"11"}; 
    NSString *url = [NSString stringWithFormat:@"http://crm.mywebsite.com/api/sync.php"]; 
    [manager POST:url parameters:params success:^(AFHTTPRequestOperation * _Nonnull operation, id _Nonnull responseObject) { 
     NSDictionary *dataDictionary = [NSJSONSerialization JSONObjectWithData:responseObject options:0 error:&testerror]; 
     NSLog(@"%@",dataDictionary); 
     _customerList = [NSMutableArray array]; 
     NSArray *customerArray = [dataDictionary valueForKey:@"kart"]; 
     for (NSDictionary *customerDictionary in customerArray) { 
      NKart *card = [NKart taskWithTitle:[customerDictionary valueForKey:@"adi"]]; 
      card.adres = [customerDictionary valueForKey:@"adres"]; 
      NSLog(@"%@",card.adres); 
      [self.customerList addObject:card]; 
      [self.tableView reloadData]; 
     } 

    } failure:^(AFHTTPRequestOperation * _Nonnull operation, NSError * _Nonnull error) { 
     NSLog(@"Error: %@",error); 
    }];

cellForRowAtIndexPath方法。

 NKart *card = [_customerList objectAtIndex:indexPath.row]; 
cell.textLabel.text= card.adi;

當我試圖在tableview中顯示它們時，我遇到了這個錯誤。

阿迪不是NSArray的

還有就是JSON

{ 
       adi = "TestFirm"; 
       adi2 = ""; 
       adi3 = ""; 
       adres = "\U0130STANBUL"; 
       email = ""; 
       email2 = ""; 
       facebook = ""; 
       fax = ""; 
       "fk_agent" = 2; 
       "fk_faaliyet_alani" = 0; 
       "fk_grubu" = 7; 
       "fk_il" = 34; 
       "fk_kaydi_yapan" = 0; 
       "fk_kaynagi" = 0; 
       id = 407; 
       "kayit_tipi" = 10; 
       ktar = "2014-10-30 16:28:00"; 
       linkedin = ""; 
       skype = ""; 
       tel1 = ""; 
       tel2 = ""; 
       twitter = ""; 
       vd = ""; 
       vn = ""; 
       www = ""; 
}

所以我'確保其未來的字符串給我。

這很容易解決。嘗試在完成解析後添加斷點。你會看到一個數組賦予一個字符串期望對象。在你實例化你的單元之前再檢查一下。 – erenkabakci

我已經在中做過了cell.textLabel.text = card.adi; 其崩潰。 –

有些東西一定是錯的card.adi –

您分配一個NSArray，而不是NSString，在這裏：

NKart *card = [NKart taskWithTitle:[customerDictionary valueForKey:@"adi"]];

你需要仔細檢查傳入的JSON，但它肯定是一個數組，而不是字符串。

你可能想：

NSArray *adi = customerDictionary[@"adi"]; 
if ([adi count] > 0) { 
    NKart *card = [NKart taskWithTitle:adi[0]]; 
    ... 
}

雖然我不知道究竟什麼是必需的;只有你做到。

那麼，日誌說這一切 - 你認爲是NSString類型的對象實際上是NSArray。由於NSArray不響應任何稱爲isEqualToString的方法，因此崩潰！

以下是可能發生的：

查看您所在NKart模型設置。雖然，您宣稱adi爲NSString，但您實際上正在鑄造NSArray至NSString。顯然你得到了一個NSArray，當你將這個對象設置爲你的標籤的文本屬性時，幕後會出現一些問題，詢問當前的字符串屬性是否與你正在設置的字符串屬性相同。這導致崩潰！

isEqualToString方法仍然在NSString類。但此方法不存在NSArray類。

提供的

NSLog(@"%@",dataDictionary);

值迅速解決您的問題。

第二次嘗試：你的代碼仍然是一些不必要的代碼。

NSDictionary *dataDictionary = [NSJSONSerialization JSONObjectWithData:responseObject options:0 error:&testerror]; 
NSLog(@"%@",dataDictionary); 
_customerList = [NSMutableArray array]; 
//NSArray *customerArray = [_customerList addObject:[dataDictionary valueForKey:@"kart"]]; 
//for (NSDictionary *customerDictionary in customerArray) { 
    NKart *card = [NKart taskWithTitle:[customerDictionary valueForKey:@"adi"]]; 
    card.adres = [customerDictionary valueForKey:@"adres"]; 
    NSLog(@"%@",card.adres); 
    [self.customerList addObject:card]; 
    [self.tableView reloadData]; 
//}

其實我編輯我的問題，並添加了json.So這是dataDictionary的日誌結果。 json返回一次？ –

或json返回頻繁？ – Jamil
