Question

如何在字符串中添加多个字符串？这是最简单的方法吗？如果我不想在每次向字符串添加内容时创建新的代码行，我想做类似的事情：

    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

我是否必须每次添加附加附加的新行？是否有更快/更有效的方式来做到这一点？

我正在尝试使用我的tableview编写电子邮件正文，这将导致一组庞大的编程行。我是否有人可以给我任何提示或者比组成一个huuuge字符串更好的东西，这样我就可以使用包含我的tableview数据的表填充我的电子邮件正文？

任何有助于提高效率的帮助表示赞赏。谢谢！卡洛斯法里尼。

//在完成它之后我得到了一些：

-(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:@"123@abc.com", nil]];
    [composer setSubject:@"subject here"];
    [composer setMessageBody:increments isHTML:YES];
    [composer setModalTransitionStyle:UIModalTransitionStyleFlipHorizontal];
    [self presentModalViewController:composer animated:YES];
    [composer release];
}else {
    [composer release];
}

}

但话说回来，它只显示了表格中的一行。我在这里做错了什么？

这样的事情怎么样：

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