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];
收到响应时
- (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;
}
当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;
}
