如何组合来自 NSMutablearray 的字符串

Question

我试图弄清楚如何将 NSMutable 数组中的数据组合成电子邮件正文的一部分。以下代码产生以下 NSLog 输出：

- (void)emailBody
{
    NSLog(@"Number of Songs: %@", profile.profileNumberOfSongs);
    NSLog(@"Profile Length:  %@", [self convertSecondstoMMSS:[profile.profileDuration intValue]]);

    for (ProfileItems *item in profileItemsNSMArray) 
    {
        NSLog(@"%@ %@ - %@ %@", item.profileItemsSongOrder, item.profileItemsMovementName, item.profileItemsArtist, item.profileItemsSong);
    }
}

NSLog 输出：

 Number of Songs: 9
 Profile Length:  40:07
 1 Seated Flat - Foo Fighters Home
 2 Seated Flat - Foo Fighters What If I Do?
 3 Standing Climb - Foo Fighters Tired Of You

将此数据存储到单个 NSString 以作为电子邮件正文传递的最佳方法是什么？

提前致谢

Answer 1

- (NSString *)emailBody
{
    NSMutableString *emailBodyString = [NSMutableString string];
    [emailBodyString appendFormat:@"Number of Songs: %@", profile.profileNumberOfSongs];
    [emailBodyString appendFormat:@"Profile Length: %@", [self convertSecondstoMMSS:[profile.profileDuration intValue]]];

    for (ProfileItems *item in profileItemsNSMArray) 
    {
        [emailBodyString appendFormat:@"%@ %@ - %@ %@", item.profileItemsSongOrder, item.profileItemsMovementName, item.profileItemsArtist, item.profileItemsSong];
    }

    return emailBodyString;
}
