문제, 마지막 행만 업데이트됩니다.

Question

UITableViewCell 안에 UIPickerView을 만들려고하는데 제대로 작동합니다. UIProgressView에 대한 태그를 indexPath.row으로 설정했습니다. 현재 내가 connection:didReceiveData: 메소드를 호출 NSURLConnection 때 NSURLConnection

을 사용하여 파일을 다운로드 할 때 내가이 UIProgressView을 사용하고 3 행 을 가지고, 내가 왜 마지막 행 만 확실하지 오전의 indexPath.row 일치하여 진행 상황을 업데이트하려고하지만

를 업데이트되는

나를 아래와 같이 사용자 정의 클래스를 만들 수

- (void)download:(NSString*)rowId 
{ 
    NSURL *url; 

    if ([rowId intValue] == 0){ 
     url = [NSURL URLWithString:@"http://192.168.0.29/iphone/video/video_10.mov"]; 
    } 
    else if ([rowId intValue] == 1){ 
     url = [NSURL URLWithString:@"http://192.168.0.29/iphone/video/video_10.mov"]; 
    } 
    else if ([rowId intValue] == 2){ 
     url = [NSURL URLWithString:@"http://192.168.0.29/iphone/video/video_10.mov"]; 
    } 



    NSURLRequest *theRequest = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:10.0]; 
    NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; 
    connection = nil; 

} 
- (void)connection:(NSURLConnection *)theConnection didReceiveData:(NSData *)recievedData { 
    if (data==nil) { 
     data = [[NSMutableData alloc] initWithCapacity:2048]; 
    } 
    [data appendData:recievedData]; 
    NSNumber *resourceLength = [NSNumber numberWithUnsignedInteger:[data length]]; 
    float progress = [resourceLength floatValue]/[self.filesize floatValue]; 
    NSLog(@"%d inside ",myId); 
    UIProgressView* downPreView = (UIProgressView*)[self.view viewWithTag:myId]; 
    downPreView.progress = progress; 

} 


// Customize the appearance of table view cells. 
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath: 
(NSIndexPath *)indexPath 
//------------------------------------------------------------------------------- 
{ 
    static NSString *CellIdentifier = @"DownloadingCell"; 

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
    if (cell == nil) 
    { 
     cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease]; 
    } 

    self.progressView = [[[UIProgressView alloc]initWithFrame:CGRectMake(80,70,170,15)]autorelease]; 
    [self.progressView setProgressViewStyle:UIProgressViewStyleBar]; 
    self.progressView.tag = indexPath.row; 
    self.progressView.progress = 0.0f; 
    myId = indexPath.row; 
    NSString *aid = [NSString stringWithFormat:@"%d",myId]; 

    NSLog(@"%@",aid); 






    [cell.contentView addSubview:self.progressView]; 
    [self performSelectorOnMainThread:@selector(download:) withObject:aid waitUntilDone:NO]; 


    if (indexPath.row == 0) 
    { 
     cell.textLabel.text = @"Beautiful Dreamer"; 
     cell.detailTextLabel.text = @"David Lehman"; 
     cell.imageView.image = [UIImage imageNamed:@"download_poem_icon.png"]; 

    } 
    else if (indexPath.row == 1) 
    { 
     cell.textLabel.text = @"Friends a Friendship"; 
     cell.detailTextLabel.text = @"Denise Levertov"; 

     cell.imageView.image = [UIImage imageNamed:@"download_poem_icon.png"]; 

    } 
    else { 
     cell.textLabel.text = @"Love and Friendship"; 
     cell.detailTextLabel.text = @"Dorianne Laux"; 
     cell.imageView.image = [UIImage imageNamed:@"download_poem_icon.png"]; 

    } 

    cell.selectionStyle = UITableViewCellSelectionStyleNone; 

    return cell; 
}

시도를 알려 주시기 바랍니다 :

@protocol CustomConnectionDelegate 

- (void)connection:(CustomConnection *)theConnection didReceiveData:(NSData *)recievedData; 

@end 
@interface CustomConnection:NSURLConnection 
{ 
    int myId; 
    id<CustomConnectionDelegate>myDelegate; 
} 
@property(nonatomic, readwrite) int myId; 
@property(nonatomic, retain) id<CustomConnectionDelegate>myDelegate;
