通过浏览iphone中的文件上传和发送文件

我正在制作一个应用程序，用户可以在其中聊天，也可以从该应用程序发送文件。但我坚持认为，用户可以通过附件向其他用户发送任何文件，但我没有找到任何示例应用程序或帮助代码，因此任何人都可以帮助我解决问题

---

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。

实现这一点的一些建议

---

首先让我给你一些建议，像这样从设备上传文件

一,

2现在只需通过ASIFormDataRequest将媒体上传到Web服务，然后他们将生成链接并返回给链接。然后，您可以通过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;


 }

与xmpp框架聊天？

-(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;
