xCode 4.2では、identifier
ストーリーボードのプロトタイプセルにプロパティを設定するUncategorized - Compilation Failed
と、プロジェクトをビルドしようとするとエラーが発生します。
あなたが必要とするすべての情報がわからないので、私が関連すると思うものを入れます...
まず、ストーリーボードの内部にテーブルビューを設定したビューコントローラがあります。テーブルビューに、プロトタイプセルを配置しました。プロトタイプセルに、UIImageViewと3つのラベルを配置しました。
DOR_SearchCustomCell
.hおよび.mファイルと呼ばれるカスタムセルクラスがあります。.hファイルは次のとおりです。
@interface DOR_SearchCustomCell : UITableViewCell {
__weak IBOutlet UIImageView *cellImage;
__weak IBOutlet UILabel *cellTitle;
__weak IBOutlet UILabel *cellText;
__weak IBOutlet UILabel *cellDistance;
}
@property (weak, nonatomic) IBOutlet UIImageView *cellImage;
@property (weak, nonatomic) IBOutlet UILabel *cellTitle;
@property (weak, nonatomic) IBOutlet UILabel *cellText;
@property (weak, nonatomic) IBOutlet UILabel *cellDistance;
@end
そして.mファイル:
#import "DOR_SearchCustomCell.h"
@implementation DOR_SearchCustomCell
@synthesize cellImage;
@synthesize cellTitle;
@synthesize cellText;
@synthesize cellDistance;
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
// Initialization code
}
return self;
}
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
[super setSelected:selected animated:animated];
// Configure the view for the selected state
}
@end
私のプロトタイプセルでは、このクラスがカスタムクラスとして設定され、スタイルがカスタムに設定され、識別子がに設定されspecialsCell
、画像とラベルがクラスファイルの変数に関連付けられています。
ビューコントローラを制御するクラスはDOR_SearchViewController
、.hファイルと.mファイルです。.hファイルは次のとおりです。

ストーリーボードにセル識別子名を入力しないと、プロジェクトがコンパイルされ、デフォルトのセルスタイル(いつ設定されるか)が取得されます。そのため、テスト目的で下部にパーツcell == nil
を追加しました。cell.textLabel.text
私はまだiPhoneのプログラミングについてあまりよく知りません。どんな助けでも大歓迎です。私が見つけたすべてのチュートリアルは、私のプロジェクトに適合していないようで(View Controller内にテーブルビューがある)、それらを実装しようとしたときに機能しませんでした。すべての回答をありがとう。さらに情報が必要な場合はお知らせください。
