将多个字符串添加到一个字符串中

Question

如何将多个字符串添加到一个字符串中？ 最简单的方法是什么？ 如果我不想每次向字符串添加内容时都创建新行代码，我想做这样的事情：

    NSString *recipeTitle = [@"<h5>Recipe name: " stringByAppendingFormat:recipe.name, @"</h5>"];
    NSLog(@"%@", recipeTitle);

    // This shows: <h5>Recipe name: myrecipe
    // Where's the </h5> closing that header ? It will only show up with the next line of code

    recipeTitle = [recipeTitle stringByAppendingFormat:@"</h5>"];

    //my problem is that will result in more than 1k lines of programming

我是否必须每次都添加一个新行附加附加内容？ 有没有更快/更高效的方法来做到这一点？

我正在尝试用我的表格视图来撰写电子邮件正文，这将导致大量的编程行。有没有人可以给我任何提示或任何比编写一个巨大的字符串更好的东西，这样我就可以用包含我的表视图数据的表格填充我的电子邮件正文？

任何有助于提高工作效率的帮助都将受到赞赏。谢谢 ！ 卡洛斯·法里尼.

// 经过一番研究后，我得到：

-(IBAction)sendmail{
MFMailComposeViewController *composer = [[MFMailComposeViewController alloc] init];
[composer setMailComposeDelegate:self];
NSString *recipeTitle = @"<h5>Recipe name: ";
recipeTitle = [recipeTitle stringByAppendingFormat:recipe.name];
recipeTitle = [recipeTitle stringByAppendingFormat:@"</h5>"];

NSString *ingredientAmount = @"";
NSString *ingredientAisle = @"";
NSString *ingredientTitle = @"";

NSString *tableFirstLine = @"<table width='90%' border='1'><tr><td>Ingredient</td><td>Amount</td><td>Aisle</td></tr>";
NSString *increments = @"";
int i=0;

for (i=0; i < [ingredients count]; i++) {
    Ingredient *ingredient = [ingredients objectAtIndex:i];
    ingredientTitle = ingredient.name;
    ingredientAmount = ingredient.amount;
    ingredientAisle = ingredient.aisle;

    increments = [increments stringByAppendingFormat:recipeTitle];
    increments = [tableFirstLine stringByAppendingFormat:@"<tr><td>"];
    increments = [increments stringByAppendingFormat:ingredientTitle];
    increments = [increments stringByAppendingFormat:@"</td><td>"];
    increments = [increments stringByAppendingFormat:ingredientAmount];
    increments = [increments stringByAppendingFormat:@"</td><td>"];
    increments = [increments stringByAppendingFormat:ingredientAisle];
    increments = [increments stringByAppendingFormat:@"</td></tr>"];
    if (i == ([ingredients count]-1)) {
        //IF THIS IS THE LAST INGREDIENT, CLOSE THE TABLE
        increments = [increments stringByAppendingFormat:@"</table>"];
    }
}

NSLog(@"CODE:: %@", increments);

if ([MFMailComposeViewController canSendMail]) {
    [composer setToRecipients:[NSArray arrayWithObjects:@"[email protected]", nil]];
    [composer setSubject:@"subject here"];
    [composer setMessageBody:increments isHTML:YES];
    [composer setModalTransitionStyle:UIModalTransitionStyleFlipHorizontal];
    [self presentModalViewController:composer animated:YES];
    [composer release];
}else {
    [composer release];
}

}

但话又说回来，它只在表中显示一行。我在这里做错了什么？

像这样的事情怎么样：

NSString *recipeTitle = [NSString stringWithFormat:@"<h5>Recipe name: %@ </h5>", recipe.name];
