ここに再び ViewControllers があります。
ここに私のViewController.hがあります:
#import <UIKit/UIKit.h>
@interface ViewController : UIViewController<UITableViewDataSource, UITableViewDelegate>
@property (copy, nonatomic) NSDictionary *firstTableView;
@property (copy, nonatomic) NSArray *firstTableViewKey;
@property (weak, nonatomic) IBOutlet UILabel *norskLabel;
@property (weak, nonatomic) IBOutlet UILabel *infinitivLabel;
@property (weak, nonatomic) IBOutlet UILabel *presensLabel;
@property (weak, nonatomic) IBOutlet UILabel *preteritumLabel;
@property (weak, nonatomic) IBOutlet UILabel *perfektumLabel;
@end
これが私のViewController.mです：
#import "ViewController.h"
static NSString *SectionsTableIdentifier = @"SectionsTableIdentifier";
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
UITableView *tableView = (id)[self.view viewWithTag:1];
[tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:SectionsTableIdentifier];
NSString *path = [[NSBundle mainBundle] pathForResource:@"SterkeVerb" ofType:@"plist"];
self.firstTableView = [NSDictionary dictionaryWithContentsOfFile:path];
self.firstTableViewKey = [[self.firstTableView allKeys] sortedArrayUsingSelector:@selector(compare:)];
tableView.backgroundColor = [UIColor clearColor];
tableView.opaque = NO;
tableView.backgroundView = nil;
// Do any additional setup after loading the view, typically from a nib.
}

cell.textLabel.text = nameSection[indexPath.row];
return cell;
}

}
}
わかりましたので、テーブル ビューをセクション (AZ) に分割しました。コードを入力すると、最初のセクションで完全に機能しました。しかし、次のセクションのセルの 1 つを押すと、最初のセクションの最初のセルと同じ情報が表示されました。なぜ？
