次の関数を実装しました。

- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row
forComponent:(NSInteger)component reusingView:(UIView *)view
{
    UIImage *img = [UIImage imageNamed:@"persona.jpeg"];
    UIImageView *temp = [[UIImageView alloc] initWithImage:img]; 
    temp.frame = CGRectMake(-70, 10, 60, 40);

    UILabel *channelLabel = [[UILabel alloc] initWithFrame:CGRectMake(50, -5, 80, 60)];
    channelLabel.text = @"persona y";
    channelLabel.textAlignment = UITextAlignmentLeft;
    channelLabel.backgroundColor = [UIColor clearColor];

    UIView *tmpView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 110, 60)];
    [tmpView insertSubview:temp atIndex:0];
    [tmpView insertSubview:channelLabel atIndex:1];

    return tmpView; 
}

結果は次のとおりです。

画面

画像とテキストを特定の行に挿入する必要がありますが、その方法はありますか？
ご助力ありがとうございます。

私のアイデアは、UIPickerViewを埋めるために写真と説明の配列を埋めることです

Arrayの時点でデータを取得してみてくださいNSDictionary。

辞書の構造：{Image:<imageName>, LabelText:<labelText>}

- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row
forComponent:(NSInteger)component reusingView:(UIView *)view
{
    NSDictionary *dict =  [datasourceArray objectAtIndex:row];
    UIImage *img = [UIImage imageNamed:[dict valueForKey:@"Image"]]; // get image path from the dictionary
    UIImageView *temp = [[UIImageView alloc] initWithImage:img]; 
    temp.frame = CGRectMake(-70, 10, 60, 40);

    UILabel *channelLabel = [[UILabel alloc] initWithFrame:CGRectMake(50, -5, 80, 60)];
    channelLabel.text = [dict valueForKey:@"LabelText"];
    channelLabel.textAlignment = UITextAlignmentLeft;
    channelLabel.backgroundColor = [UIColor clearColor];

    UIView *tmpView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 110, 60)];
    [tmpView insertSubview:temp atIndex:0];
    [tmpView insertSubview:channelLabel atIndex:1];

    return tmpView;
}
