iphone - UIPasteBoard 不粘贴音频文件？

Question

我正在开发一个应用程序，其中一个模块是一个简单的列表 TableView，显示音频文件列表。当用户选择任何音频文件时，操作表会附带选项 SMS 之一。我需要通过短信发送特定的音频文件。请让我知道如何处理这个问题。

如果这是不可能的，请向我提供苹果文档，以便它作为我展示的证据。

这是我尝试粘贴音频文件的方法...

第一种方法:

UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
NSString *path = [[NSBundle mainBundle] pathForResource:@"audiofilename" ofType:@"caf"];
NSData *myData = [NSData dataWithContentsOfFile:path];
[pasteboard setData:myData forPasteboardType:@"audiofile"];
NSString  *copyPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/audiofile.caf"];
NSURL *sndURL = [NSURL fileURLWithPath:copyPath];
[pasteboard setString:[NSString stringWithFormat:@"%@",sndURL]];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:@"sms:12345678"]]];

第二种方式:

Class messageClass = (NSClassFromString(@"MFMessageComposeViewController"));

if([messageClass canSendText])
{
    messagepicker = [[MFMessageComposeViewController alloc] init];
    messagepicker.messageComposeDelegate = self;
    UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
    NSString *path = [[NSBundle mainBundle] pathForResource:@"290912044119" ofType:@"caf"];
    NSData *myData = [NSData dataWithContentsOfFile:path];
    [pasteboard setData:myData forPasteboardType:@"audiofile"];
    NSString  *copyPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/audiofile.caf"];
    NSURL *sndURL = [NSURL fileURLWithPath:copyPath];
    [messagepicker setBody:[NSString stringWithFormat:@"%@",sndURL]];
    [self presentModalViewController:messagepicker animated:YES];
    [[UIApplication sharedApplication] setStatusBarHidden:YES];
}

我知道这可以通过发布到服务器并从那里检索来实现。但是，这不是要求。

任何帮助将不胜感激，如果不可能，请提供苹果文档。

It is not possible to send an audio file from message with current sdk....You can reach this requirement by upload that sound file to server and then send that url from message.
