Iphone ASIHTTPRequestErrorDomain代码=4“;请求被取消了
下面的函数没有从服务器下载内容,它给出了一个HttpRequestErrorDomain Code=4“请求被取消 此函数是从viewdidload调用的。但是相同的URL工作正常,它在-(void)downLoad:(id)sender event:(id)event函数中下载内容,但不在-(void)startDownload函数中。 请让我知道我的函数(((void)startDownload)中的问题/错误是什么 以下功能正常运行Iphone ASIHTTPRequestErrorDomain代码=4“;请求被取消了,iphone,ios,ios4,asihttprequest,Iphone,Ios,Ios4,Asihttprequest,下面的函数没有从服务器下载内容,它给出了一个HttpRequestErrorDomain Code=4“请求被取消 此函数是从viewdidload调用的。但是相同的URL工作正常,它在-(void)downLoad:(id)sender event:(id)event函数中下载内容,但不在-(void)startDownload函数中。 请让我知道我的函数(((void)startDownload)中的问题/错误是什么 以下功能正常运行 -(void)downLoad:(id)sender e

下面的函数不起作用,并给出HttpRequestErrorDomain Code=4“请求被取消”
-(void)startDownload{
if([self.myUrlArray count] > 0 ){
int count = [self.myUrlArray count];
int i = count - count;
NSLog(@"%d iiiiii",i);
NSIndexPath *myIP = [NSIndexPath indexPathForRow:i inSection:0];
UITableViewCell *Cell = [self.tblViewDownload cellForRowAtIndexPath:myIP];
progress = [[UIProgressView alloc]initWithProgressViewStyle:UIProgressViewStyleBar];

progress.progress = 0.0;
progress.backgroundColor = [UIColor redColor];

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];
}
}
我想你忘了设置
IsRequestCompleted=NO代码>在第二个函数中。还有,为什么要发送cancelAllOperations?这很有可能成为问题所在
此外,无需自动释放self.networkQueue并每次重新初始化它。只需为类设置一次,并在-dealoc
中发布,直接添加到单元格[cell.contentView addSubview:progress]也是个坏主意;重复使用会破坏你的逻辑,但我没听清楚。
