NSURLConnect只工作一次

Question

我正在尝试做一个请求，但它只在第一次工作....

这是我的代码：

NSArray *infos = [rows objectAtIndex:indexPath.row];
NSString *thumbPath = thePath;

NSURLRequest *thumbRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:thumbPath]cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:10];

self->thumbConnection = [[NSURLConnection alloc] initWithRequest:thumbRequest
                                                        delegate:self
                                                startImmediately:YES];

     self->thumbData = [[NSMutableData alloc]init];

收到回复时

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {

if (self->thumbData == nil) {
    self->thumbData = [[NSMutableData alloc]init];
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {

self.thumbImage.image = [UIImage imageWithData:self->thumbData];

self.thumbActivityView.hidden = YES;

self->thumbData = nil;
}

当didFinishDownloading：    - （void）connectionDidFinishLoading：（NSURLConnection *）connection {

self.thumbImage.image = [UIImage imageWithData:self->thumbData];

self.thumbActivityView.hidden = YES;

[self->thumbData release];

self->thumbData = nil;

}

超时或其他错误方法时：

   - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
[self->thumbData release];
self->thumbData = nil;
self.thumbActivityView.hidden = YES;
[thumbConnection release];
self->thumbConnection = nil;

}

如果非零，请不要再分配。最好还是在对象的init方法中分配它，并在对象的dealloc方法中释放它
