将文件上传到服务器以在iPhone中显示UIProgressView吗？

Question

I have upload a file through my server and its working fine, but i want to show a progressview for upload status, How to do this, Please help me

Thanks in Advance

I tried this:

        [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"file\"; filename=\"%@\"\r\n",file] dataUsingEncoding:NSUTF8StringEncoding]];
        [body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
        [body appendData:Filedata];
        [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
        [request setHTTPBody:body];


        NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:request delegate:self];
        if (theConnection)
            mutaebleData = [[NSMutableData data] retain];
        else
            NSLog(@"No Connection");

Using this delegate to Upload data status, but it wont help

- (void)request:(NSURLConnection *)request 
didSendBodyData:(NSInteger)bytesWritten totalBytesWritten:(NSInteger)totalBytesWritten totalBytesExpectedToWrite:(NSInteger)totalBytesExpectedToWrite
{
    NSLog(@"%d bytes out of %d sent.", totalBytesWritten, totalBytesExpectedToWrite);
}

Answer 2

This is the Best Custom controller for you.

It Custom UIActivityIndicator that you can found from this link

https://github.com/jdg/MBProgressHUD

These is not apple specific controls. This MBProgressHUD controls consist of Three controls that describe in below.

• Background UIImageView with the image.
• UIActivityIndicatory
• UILabel with whatever message you want to display.

MBProgressHUD is an iOS drop-in class that displays a translucent HUD with an indicator and/or labels while work is being done in a background thread. The HUD is meant as a replacement for the undocumented, private UIKit UIProgressHUD with some additional features.......

The simplest you can alert a UIProgressView and int the delegate you can set the value of progress for example:

- (void)request:(NSURLConnection *)request 
didSendBodyData:(NSInteger)bytesWritten totalBytesWritten:(NSInteger)totalBytesWritten totalBytesExpectedToWrite:(NSInteger)totalBytesExpectedToWrite
{
    NSLog(@"%d bytes out of %d sent.", totalBytesWritten, totalBytesExpectedToWrite);

    UIProgressView *progressView = [[UIProgressView alloc] initWithProgressViewStyle:UIProgressViewStyleDefault];
    [self.view addSubview:progressView];
    progressView.progress = (double) bytesWritten / totalBytesWritten;
}
