下面的函数不从服务器下载内容,它给出ASIHTTPRequestErrorDomain代码= 4”请求被取消。ASIHTTPRequestErrorDomain代码= 4“请求被取消
这个函数是从viewdidload调用的,但是相同的url正常工作,并且它正在下载内容 - (void)downLoad:(id)发件人事件:(id)事件函数,但不在 - (void)startDownload函数。
请让我知道是什么问题/错误的事情在我的功能( - (无效)startDownload)
以下功能工作正常
-(void)downLoad:(id)sender event:(id)event{
self.tblViewDownload.userInteractionEnabled = NO;
IsRequestCompleted = NO;
CGPoint touchPosition = [[[event allTouches] anyObject] locationInView:self.tblViewDownload];
NSIndexPath *indexPath = [self.tblViewDownload indexPathForRowAtPoint:touchPosition];
UITableViewCell *Cell = [self.tblViewDownload cellForRowAtIndexPath:indexPath];
progress = [[UIProgressView alloc]initWithProgressViewStyle:UIProgressViewStyleBar];
progress.frame = CGRectMake(65, 55, 210, 25);
progress.progress = 0.0;
[Cell.contentView addSubview:progress];
UIButton* button = (UIButton*)sender;
button.hidden=YES;
if(!self.networkQueue)
self.networkQueue = [[[ASINetworkQueue alloc] init] autorelease];
[self.networkQueue cancelAllOperations];
[self.networkQueue setQueueDidFinishSelector:@selector(queueCompleted:)];
[self.networkQueue setShowAccurateProgress:YES];
[self.networkQueue setDownloadProgressDelegate:progress];
[self.networkQueue setDelegate:self];
NSDictionary *aDict =[self.myUrlArray objectAtIndex:[indexPath row]];
NSString *aImgUrl = [aDict objectForKey:@"IMG_URL"];
NSString *aVideoUrl = [aDict objectForKey:@"VIDEO_URL"];
NSString *aAudioUrl = [aDict objectForKey:@"AUDIO_URL"];
NSArray *aPoemArrayUrls = [NSArray arrayWithObjects:aImgUrl,aVideoUrl,aAudioUrl,nil];
for(NSString* urlString in aPoemArrayUrls)
{
NSURL *url = [NSURL URLWithString:urlString];
ASIHTTPRequest *downloadAFileRequest = [[ASIHTTPRequest requestWithURL:url]retain];
NSString *Filename = [urlString lastPathComponent];
NSLog(@"%@ filename",Filename);
[downloadAFileRequest setUserInfo:[NSDictionary dictionaryWithObject:@"request1" forKey:@"name"]];
[downloadAFileRequest setDownloadDestinationPath:[[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"] stringByAppendingPathComponent:Filename]];
[downloadAFileRequest setShouldContinueWhenAppEntersBackground:YES];
[downloadAFileRequest setDelegate:self];
[downloadAFileRequest setDidFinishSelector:@selector(requestDone:)];
[downloadAFileRequest setDidFailSelector:@selector(requestWentWrong:)];
[downloadAFileRequest setShowAccurateProgress:YES];
[self.networkQueue addOperation:downloadAFileRequest];
//----
}
[self.networkQueue go];
}
以下功能不工作并给出ASIHTTPRequestErrorDomain代码= 4“请求被取消
-(void)startDownload{

也不好主意直接添加到单元格[Cell.contentView addSubview:progress];重复使用会破坏你的逻辑 – NeverBe 2012-08-08 14:01:32
同意NeverBe,没有抓住那个。 – 2012-08-08 14:10:04
