我实现了下面的代码，并记录了

arrayPlainText

，但当我在模拟器和iPhone上运行它时，它只显示第一项，其他所有内容都消失了

NSMutableArray *xmlListContent;
    NSFileManager *fileManager = [NSFileManager defaultManager];
    if ([fileManager fileExistsAtPath:[self returnListPath]])
    {
        xmlListContent = [[NSMutableArray alloc] initWithContentsOfFile:[self returnListPath]];
        NSMutableArray *listContent = [[NSMutableArray alloc] init];
        int i;
        for(i = 0; i < [xmlListContent count]; i++)
        {
            MFMailComposeViewController *mailComposer = [[MFMailComposeViewController alloc] init];
            [mailComposer setMailComposeDelegate:self];
            if ([MFMailComposeViewController canSendMail]) {
                [mailComposer setSubject:editedListTitle];
                [mailComposer setModalTransitionStyle:UIModalTransitionStyleCoverVertical];
                NSString *item = [NSString stringWithString:[[xmlListContent objectAtIndex:i] objectForKey:@"label"]];
                NSString *tempString = [NSString stringWithFormat:@"-%@",item];
                [listContent addObject:tempString];

                NSString *arrayPlainText = [listContent componentsJoinedByString:@"<br>"];
                [mailComposer setMessageBody:[NSString stringWithFormat:@"<html>%@</html>",arrayPlainText] isHTML:YES];
                DLog(arrayPlainText);

                [self presentModalViewController:mailComposer animated:YES];
            }
        }
    }
    else
    {
        xmlListContent = [NSMutableArray array];
        DLog(@"failed to compose list via email");
    }

NSMutableArray*xmlListContent；
NSFileManager*fileManager=[NSFileManager defaultManager]；
如果（[fileManager fileExistsAtPath:[self returnListPath]]）
{
xmlListContent=[[NSMutableArray alloc]initWithContentsOfFile:[self returnListPath]]；
NSMutableArray*listContent=[[NSMutableArray alloc]init]；
int i；
对于（i=0；i<[xmlListContent count]；i++）
{
MFMailComposeViewController*mailComposer=[[MFMailComposeViewController alloc]init]；
[mailComposer setMailComposeDelegate:self]；
如果（[MFMailComposeViewController canSendMail]）{
[mailComposer设置主题：editedListTitle]；
[mailComposer SetModAltTransitionStyle:UIModAltTransitionStyleCoverVertical]；
NSString*item=[NSString stringWithString:[[xmlListContent objectAtIndex:i]objectForKey:@“标签”]；
NSString*tempString=[NSString stringWithFormat:@“-%@”，项]；
[listContent-addObject:tempString]；
NSString*arrayPlainText=[listContent组件通过字符串连接：@“
”；
[mailComposer setMessageBody:[NSString stringWithFormat:@“%@”，ArrayPlaintText]isHTML:是]；
DLog（arrayPlainText）；
[self-presentModalViewController:mailComposer动画：是]；
}
}
}
其他的
{
xmlListContent=[NSMutableArray]；
DLog（@“无法通过电子邮件撰写列表”）；
}

这个代码怎么样：

NSString *item = [NSString stringWithString:[[self.array objectAtIndex:i] objectForKey:@"label"]];
NSString *tempString = [NSString stringWithFormat:@"-%@",item];
[listContent addObject:tempString];

NSString *arrayPlainText = [listContent componentsJoinedByString:@"<br>"];
[mailComposer setMessageBody:[NSString stringWithFormat:@"<html>%@</html>",arrayPlainText] isHTML:YES];
DLog(arrayPlainText);

NSString*item=[NSString stringWithString:[[self.array objectAtIndex:i]objectForKey:@“label”]；
NSString*tempString=[NSString stringWithFormat:@“-%@”，项]；
[listContent-addObject:tempString]；
NSString*arrayPlainText=[listContent组件通过字符串连接：@“
”；
[mailComposer setMessageBody:[NSString stringWithFormat:@“%@”，ArrayPlaintText]isHTML:是]；
DLog（arrayPlainText）；

答案就在这里

NSMutableArray *xmlListContent;
NSFileManager *fileManager = [NSFileManager defaultManager];
if ([fileManager fileExistsAtPath:[self returnListPath]])
{
    xmlListContent = [[NSMutableArray alloc] initWithContentsOfFile:[self returnListPath]];
    NSMutableArray *listContent = [[NSMutableArray alloc] init];
    int i;
    for(i = 0; i < [xmlListContent count]; i++)
    {
        NSString *item = [[xmlListContent objectAtIndex:i] objectForKey:@"label"];
        NSString *tempString = [NSString stringWithFormat:@"-%@", item];
        [listContent addObject:tempString];
    }

    NSString *arrayPlainText = [listContent componentsJoinedByString:@"<br>\n"];
    DLog(arrayPlainText);

    if ([MFMailComposeViewController canSendMail]) {
        MFMailComposeViewController *mailComposer = [[MFMailComposeViewController alloc] init];
        [mailComposer setMailComposeDelegate:self];

        [mailComposer setSubject:editedListTitle];
        [mailComposer setModalTransitionStyle:UIModalTransitionStyleCoverVertical];

        [mailComposer setMessageBody:[NSString stringWithFormat:@"<html>%@</html>",arrayPlainText] isHTML:YES];

        [self presentModalViewController:mailComposer animated:YES];
    }
    else
    {
        xmlListContent = [NSMutableArray array];
        DLog(@"failed to compose list via email");
    }
}

NSMutableArray*xmlListContent；
NSFileManager*fileManager=[NSFileManager defaultManager]；
如果（[fileManager fileExistsAtPath:[self returnListPath]]）
{
xmlListContent=[[NSMutableArray alloc]initWithContentsOfFile:[self returnListPath]]；
NSMutableArray*listContent=[[NSMutableArray alloc]init]；
int i；
对于（i=0；i<[xmlListContent count]；i++）
{
NSString*item=[[xmlListContent对象索引：i]objectForKey:@“标签”]；
NSString*tempString=[NSString stringWithFormat:@“-%@”，项]；
[listContent-addObject:tempString]；
}
NSString*arrayPlainText=[listContent componentsJoinedByString:@“
\n”]；
DLog（arrayPlainText）；
如果（[MFMailComposeViewController canSendMail]）{
MFMailComposeViewController*mailComposer=[[MFMailComposeViewController alloc]init]；
[mailComposer setMailComposeDelegate:self]；
[mailComposer设置主题：editedListTitle]；
[mailComposer SetModAltTransitionStyle:UIModAltTransitionStyleCoverVertical]；
[mailComposer setMessageBody:[NSString stringWithFormat:@“%@”，ArrayPlaintText]isHTML:是]；
[self-presentModalViewController:mailComposer动画：是]；
}
其他的
{
xmlListContent=[NSMutableArray]；
DLog（@“无法通过电子邮件撰写列表”）；
}
}

如果打印arrayPlainText的内容，它是否包含所有的值？是的，它具有所有完整的输出，但是当它在composer中时，它没有。您能提供更多的代码吗？您使用的变量没有向我们显示它们的声明。
