通过iphone浏览文件上传和发送文件

Question

我正在制作一个应用程序，用户可以在其中聊天&也从该应用程序发送文件。但我被困在用户可以通过附件向其他用户发送任何文件的地方，但我没有找到任何示例应用程序或帮助代码，所以可以任何人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浏览上传和发送文件的技术。

Answer 1

实现这一目标的一些建议

浏览

上传聊天

Answer 2

让我给你一些建议首先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asformdatarequest将媒体上传到webservices，然后它们将生成链接并返回链接。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;

 }
