全て。NSTableView を使用すると、この関数に到達する限り、次のエラーが発生します。

-(id)tableView:(NSTableView *)tableView viewForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row{

USBInfor* usbInfor = [_tableContent objectAtIndex:row];
NSString* identifier = [tableColumn identifier];

return [usbInfor valueForKey:identifier];
}

USB の名前、サイズ、パス、およびタイプを保存するための usbInfor クラスを作成しました。そして、これらの変数を _tableContent NSMutableArray に追加します。

 USBInfor *usbinfor = [[USBInfor alloc]init];
 usbinfor.name = [mountPath substringFromIndex:9];
 usbinfor.path = mountPath;
 usbinfor.size = formattingSize;
 usbinfor.type = type;

 [_tableContent addObject:usbinfor];

xib ファイルに 3 つの列を作成し、名前、パス、サイズである変数の名前と同じ名前を付けた識別子をそれぞれ作成しました。

エラーは次のとおりです。

メソッド tableView:viewForTableColumn:row: は、NSView または NSView のサブクラスを返す必要があります。[usbInfor valueForKey:identifier] のように見えます。ここで、識別子は "name" で、文字列 ([mountPath substringFromIndex:9]) を返します。あなたがそこで何をしようとしているのかわかりませんが、それは明らかに間違っています。

[テーブル列識別子] は、列名を識別するために使用されます。だから、それは次のようなものでなければなりません

NSString *filename = [[itemArray1 objectAtIndex:rowIndex] objectForKey:key1a];
NSString *path = [[itemArray1 objectAtIndex:rowIndex] objectForKey:key1b];

NSString *identifier = [tableColumn identifier];
if ([identifier] isEqualToString:@"whatever a column name is"]) {
    return filename;
}

else if ([identifier] isEqualToString:@"whatever a column name is"]) {
    return path;
}
