他の 2 つのクラスによってサブクラス化されるUITableViewControllerサブクラスがあります。両方のテーブルの一部のセルには、ユーザーがクリックしてアクションを実行できる画像があります。それはすべて機能し、2 つのサブクラスの 1 つで、そのテーブルの最初の行に問題があることを除いて、私は満足しています。画像をクリックするには、画像の右端をクリックする必要があります。画像の本文をクリックすると、代わりにテーブルの didSelectRowAtIndexPath が呼び出されます。
私を悩ませているのは、それがすべての行の他のクラスで機能し、その画像が表示される他のすべての行で機能しないクラスでも機能することです。画像とジェスチャ認識エンジンをセルに追加するために使用しているコードは次のとおりです。
UIImageView *imgparent = [[UIImageView alloc] initWithFrame:CGRectMake(offsetleftmain, 24.0, 14.0, 16.0)];
imgparent.image = [UIImage imageNamed:@"item_open.png"];
imgparent.tag = ITEMOPENTAG;
// add listener
imgparent.userInteractionEnabled = YES;
UITapGestureRecognizer *singleFingerDTapParent = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(loadChildren:)];
[imgparent addGestureRecognizer:singleFingerDTapParent];
[singleFingerDTapParent release];
[cell.contentView addSubview:imgparent];
[imgparent release];
ちなみに、シミュレーターでテストしています。画像をボタンに置き換えてみましたが、それでも問題は解決しません。何か案は？
編集:これは、画像がクリックされたときに呼び出されるコードの始まりです。繰り返しますが、これは機能しますが、その 1 つの行の場合は、画像の右端をクリックした場合にのみ機能します。説明のためにスクリーンショットを添付しました。最初の円は、ジェスチャを呼び出すためにタップする必要がある場所を示しています。2 番目の例は、画像全体をクリックできる同じ表の例を示しています。私は当惑しています。

NSLog(@"loadChildren");

UITableViewCell *cell = (UITableViewCell *)gestureRecognizer.view.superview.superview;
UIImageView *imgvw = (UIImageView *)[cell viewWithTag:ITEMOPENTAG]; // open arrow

}
編集：これが完全tableView:cellForRowAtIndexPath:indexPathです。cellForRowAtIndexPathこのクラスの他の 2 つのサブクラスから呼び出され、それぞれが単に識別子を渡すことに注意してwithTypeください。
