我正在制作一个应用程序，用户可以在其中聊天并从该应用程序发送文件。但是我坚持用户可以通过附件将任何文件发送给其他用户，但我没有找到任何示例应用程序或帮助代码，所以任何人都可以帮助我解决我的问题。
告诉我一些示例应用程序链接以及通过使用应用程序从 iPhone 浏览文件来上传和发送文件的技术。

让我先给你一些建议，像这样从设备上传文件
1.
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
NSString *mediaType = info[UIImagePickerControllerMediaType];
if ([mediaType isEqualToString:(NSString *)kUTTypeImage])
{
// Media is an image
picImage = [info objectForKey:UIImagePickerControllerOriginalImage];
NSString *imagePath = [NSHomeDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:@"Documents/image.jpg"]];
filePath = imagePath;
[UIImageJPEGRepresentation(picImage, 1.0) writeToFile:imagePath atomically:YES];
arrayMute = (NSMutableArray*) [self sendData:filePath]
}
}
2 现在只需通过 ASIFormDataRequest 将媒体上传到网络服务，然后他们将生成链接并返回给链接。然后你可以通过 xmpp 将该链接发送给另一个用户。然后其他用户可以下载该媒体。
-(NSMutableArray*)sendData:(NSString*)multiMData
{
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:[NSURL URLWithString:@"http://194.158.1.25/IphoneVideoService/webservice.asmx/GetData1"]];
[request addRequestHeader: @"Content-Type" value:
@"application/x-www-form-urlencoded"];
[request setDelegate:self];
[request setDidFailSelector:@selector(uploadFailed:)];
[request setUploadProgressDelegate:progressToDownload];
[request setDidFinishSelector:@selector(uploadFinished:)];
[request setDidFinishSelector:@selector(requestFailed:)];
[request setDidFinishSelector:@selector(requestFinished:)];
[request setShouldContinueWhenAppEntersBackground:YES];
NSString *url = [[NSURL fileURLWithPath:multiMData] path];
[request setFile:url withFileName:[NSString stringWithFormat:@"Hello.jpeg"] andContentType:@"image/jpeg" forKey:@"file"];
[request setTimeOutSeconds:50000];
[request setRequestMethod:@"POST"];
[request startSynchronous];
SBJSON *sbJason = [[SBJSON alloc] init];
NSMutableArray *getUploadArray = [sbJason objectWithString:responseForMedia];
return getUploadArray;
}
